Decided I'd shake things up a bit this month, after keeping the same look for nearly three straight months. Thus, I present:

icons: Area o.43
gtk+: Rele (Rezlooks engine)
xfwm4: Rezlooks-gtk (yes, it is confusingly named)
background: rassilon

It's grungy, but rather sleek. Surprisingly easy on the eyes, too. The lighter elements of the Rele gtk+ theme aren't overpoweringly white, but are just light enough to provide a decent contrast to the generally darker Area icons.

There's also an uncluttered version here.

I've been looking to assemble themes that are grungy, and themes that are warmer-yet-wintry. I like winter. I still have some hope that these 80 degree weeks will come to an end soon. We're almost to the middle of November. Surely we'll see gray sky, cool breezes, and maybe even rain here in SoCal at some point, right? Right? Well, if not, I can at least put it on my desktop.

Gosh, just look at all the buzzwords in the title!

As you may have guessed, I'll be talking a bit about the recent developments on the FOSS drivers for RadeonHD cards, specifically for R700 cards. And some other hardware stuff.

Radeon

Yesterday, October 3, I made some big ol' changes to my workstation.

I decided to try out the new video driver stack that all the kids have been talking about. Kernel Mode Setting, git Mesa/xf86-video-ati/libdrm, git kernel 2.6.32_rc1-git3. All that jazz. I wanted to see if the 3D and KMS features were really working on my RadeonHD 4550 or not. I normally run a stable graphics stack, with ~arch Mesa/x86-video-ati/libdrm where necessary to keep up on 2D acceleration and features.

This was a big leap for me. So I first consulted some of the X11 team members, remi and nirbheek, who were quite helpful. I installed the latest git-sources kernel, which at the time was 2.6.32_rc1-git3. Mike Pagano has since added -git5. Next, I downloaded the individual -9999 ebuilds for the git master packages from the X11 overlay, stuck 'em in my local overlay, and merged 'em. Only thing left to do was reboot.

Lemme tell ya -- KMS in action is awesome. The console output is just beautiful, and there's no more flickering when SLiM and Xfce load.

I did notice some minor graphical corruption of the default mouse pointer. However, the corruption isn't present when using any pointer but the default "arrow", and it also isn't seen when hovering inside a Firefox window. I was told this is because Firefox uses its own cursors. Anyway, I reported the bug upstream.

Disclaimer: I know glxgears isn't a benchmark. But folks always want to know its results anyway. I tried running glxgears, which gave me a result of over 1300FPS with desktop compositing activated. My window manager is xfwm4, so all compositing is via Xrender, not OpenGL. Disabling compositing resulted in a 500FPS boost to over 1800FPS. What's this mean? Who knows. Probably nothing. Moving on.

I took the advice of my fellow developers on IRC and installed quake3-demo. Couldn't run it, though. It blanked the screen, then a message from my LCD firmware appeared, some kind of "input not supported" or "input not detected" error. It slowly repeated the window, drawiing it from center to the top right. I had to Ctrl-Alt-Bksp to get to the console. It also locked up SLiM in the background, pegging one of my CPU cores at 100%. At this point, I rebooted just to test that KMS was still working, then called it a night.

Today, I revisited my pointer corruption bug tried the workarounds posted by Alex Deucher. To my surprise, each one worked! Booting with radeon.modeset=0 removes the glitch, though it makes each boot extremely ugly, of course. Specifying EXANoDownloadFromScreen "true" in /etc/X11/xorg.conf also fixes the corrupted pointer, though it may also be slowing down all screen drawing operations by the tiniest bit. The jury's still out on that one; it may just be my imagination. I decided to keep this second fix, as KMS is just too glorious to throw out. I like pretty boots.

I also revisited quake3-demo, since I found some pointers on the Phoronix forums that had a workaround, which is to run OpenGL applications prefixed by LIBGL_ALWAYS_INDIRECT=1. To my surprise, this worked nicely. I tested resolution has high as 900-something by 720. My screen is 1440x900, but I haven't felt like pushing it that far, yet. The game is fluid and playable. I need to figure out how to display FPS so I can properly record what I'm seeing.

With the success of Q3demo, I remembered that QuakeLive has recently added Linux support. I installed the add-on for Firefox and tried it out. Works nicely, though I'm also running Firefox with LIBGL_ALWAYS_INDIRECT=1 just to be sure. As Alex Deucher and John Bridgman have pointed out on the Phoronix forums, that variable really isn't the safest thing to do, since if something crashes it can take down the whole X server, not just the application. However, it's also the only way I get working 3D games.

QuakeLive is pretty playable, though the framerates in a few places aren't smooth -- I can't tell if this is because of my card's capabilities, or the driver stack, or the whole weird idea of playing a 3D first-person shooter inside a web browser. The big problem with QuakeLive is that the sound is terribly distorted: the voices are greatly drawn-out and slowed down, like playing an old tape recorder at 1/4 speed. There are some solutions on the QL forums, but they're mainly for Ubuntu/Pulseaudio users. I haven't found anything that works for me, yet. The effects and music are okay; it's just the voices that lag horribly.

I've also installed the latest Nexuiz, version 2.5.2, in anticipation of future testing. One of these days I'll reinstall UT2004, but I haven't read any succesful reports of that game on R700 cards. There's a lot of testing to do in the future!

Overall, I'm thrilled with the new driver hotness for my ATI card. I bought it specifically because I knew the 2D support at the time was excellent, and because there would be so many good things coming down the way for other features, including 3D acceleration. (Yes, just like the latest XKCD strip. I swear, it's like that guy listens to everything I say and watches everything I do. It's really spooky!)

Hats off to all the developers for making it happen. Many thanks!

SSD

After August's fiasco with a defective SSD, I decided to use my refund from the RMA and order a different SSD a few days ago. This time I've settled on a SanDisk enterprise SSD from an HP blade server. Only cost $49, no shipping charges. Brand new. eBay for the win.

It packs 16GB of SLC flash, which makes it perfect for mounting /usr/portage and /var on it. This way I can feel free to sync whenever I want, instead of only once a week or more. My system drive uses MLC flash, so I've been trying to ease the write load on it, which means putting the high-write activity on a dedicated disk.

The SanDisk SSD "only" has sustained reads/writes at 60MB/sec, but that's plenty for syncing Portage, as the real limiter is not how fast data can be dumped to the disk, but how fast the rsync servers can send it to my box. Same for /var writes -- it's mostly just log files and some tiny temp things, as /var/tmp is already mounted on a RAMdisk. No large files that need >100MB/sec bandwidth. I'm lookin' forward to shovin' it in my box!

More hardware

Since September 28 was my birthday and all, I've been treating myself to various bits of cheap hardware. Like a replacement AC adapter for my DC PicoPSU. The current AC brick is rated at 102W, which is way more than I need, but the problem is that it spins up its tiny fan at only 50%-75% load. This means that opening up a bunch of tabs, compiling packages, playing Quake, watching large-sized Hulu videos and whatnot turns on the fan right away. And it's the world's most annoying fan. It's loud, whiny, it hisses, and it blows the bad smell of very hot electronics out into the room. Lemme tell you, hot plastic and PSU guts do not smell good.

I just ordered a replacement fanless adapter. This thing is high-quality, designed to run very cool. And it's rated at 150W output, meaning it can match my 150W PicoPSU. My max system draw is maybe 60W, but I'll have overhead room in case I ever feel like upgrading a key component somewhere.

I also bought a $40 wireless router, an Asus WL-520gU. I already have a WL-500gP v2, which I hacked and flashed with DD-WRT a long time ago. This new router is so that I can hook up my Xbox 360 to the network without having to run 50 feet of cable across the carpet. I chose the 520gU instead of the gC because the gU supports Xlink Kai, which seems prett cool to me, as I don't have a Gold Live account. Yay for tricky internets. Apparently it's pretty common to buy a cheap wireless router and put it into client mode, rather than buying the $100 official USB dongle . . . which doesn't even support WPA2-AES or any decent security. Asus routers are known for excellent open-source support, and I've had nary a complaint about my current one. Yay for Linux on routers! Yay for online gaming!

Oh yes, and before I forget, this month's Xfce desktop:

It's October, but my current desktop is so pretty (gallery link) I haven't felt the need to switch for the last couple of weeks. There's another clean version that just shows off the wallpaper in my devspace.

Six months ago I posted some benchmarks of popular gtk+ engines. It's time to revisit those benchmarks and test the engines again, this time using FOSS drivers for my new hardware.

Today I installed my brand-spankin' new graphics card, an ATI RadeonHD 4550, by Sapphire. Getting working 2D acceleration with EXA was a cinch, now that the 2.6.30 kernel is out. Doesn't require anything special in terms of packages; nothing from overlays or bleeding-edge git checkouts. Only needs three ~arch packages: gentoo-sources, libdrm, and mesa.

For this updated round of testing, I used the same gtk+ engines, but also added some new ones. These can all be obtained by installing the following packages: gtk-engines, gnome-themes, gtk-engines-aurora, gtk-engines-candido, gtk-engines-rezlooks, and gtk-engines-xfce. New to the testing list are the Crux, ThinIce, HighContrast, and Redmond95 engines.

Once again, gtkperf-0.40 was used to obtain these benchmarks. With the exception of the graphics hardware and driver, the testing environment is mostly the same. Xfce has been updated to 4.6.1.

Let's see how all these engines perform on my Xfce workstation, eh?

Notes on the hardware:

CPU: Athlon 64 X2 4600+
Graphics: ATI RadeonHD 4550, DVI 1440x900 @ 60Hz
RAM: 4GB DDR2-667
Mobo: ASUS M3N78-VM

Notes on the testing environment:

OS: Gentoo Linux (duh)
Kernel: Linux 2.6.30-gentoo-r1 #1 SMP PREEMPT x86_64
xf86-video-ati: 6.12.1-r1
CFLAGS: -march=athlon64-sse3 -O2 -fomit-frame-pointer
DE: Xfce 4.6.1
- Xfwm4 with Composite enabled, effects: drop shadows & transparency
- Open applications: 2 instances of x11-terms/terminal

Custom themes are noted with *. These are personal themes I've made, nothing more than simple color modifications of an existing freely available theme. No additional images are used, so rendering time should not be affected.

All tests were conducted 3 times, using a Test Round setting of 100. I picked the best score of the 3, as I was looking for best-case usage conditions. The results are ranked in order from fastest to slowest.

Interesting. Six months (and one new graphics card and driver) later, there's been a bit of a shuffle. All engines tested are clustered much closer together. There used to be a 12-second gap between the fastest and slowest engines. Now it's only 3 seconds. Part of that disparity comes from new versions of the engines. Aurora in particular has made phenomenal improvements since 1.4; the numbers you see here are from version 1.5.1. It's no longer at the back of the pack -- last place now belongs to Candido, which is still rather slow, especially in the ComboBox tests.

Curiously, although the completion times are stacked very closely, there seemed to be a general slowdown. While the older gtk+ engines still turn in respectable times, they're not always at the front of the pack. In particular, the Pixmap engine, which has historically had a speedy reputation, is now trailing most other engines. The theme used is extremely simple. I'm not sure what's causing the slowdown here. Perhaps its reputation for speed is no longer deserved; even six months ago it wasn't a standout.

There's no longer an engine that can turn in 3-second completion times; in fact, the four fastest engines all tied at 4.7 seconds. Of the four, Rezlooks is without a doubt the prettiest. Many of the screenshots in my devspace feature Rezlooks themes.

Two of the engines added for this round of benchmarks, Crux and Redmond95, end up in the middle of the pack. They're not particularly fast, nor are they pleasing to the eye. The other two newcomers, ThinIce and HighContrast, distinguish themselves by jumping to the very top of the charts. HighContrast is undoubtedly the ugliest engine presented here, while ThinIce's appearance rather resembles Mist. It's tolerable, but nothing I'd use, personally.

Once again, I'll stick with Rezlooks-based themes, as well as the occasional standout Pixmap or Clearlooks theme such as ClearLUX. ClearLUX in particular is extremely easy on the eyes when doing late-night computer work.

But where are the Xfce engine results? Let's take a look . . .

The Xfce engine results baffled me. The completion times varied wildly, everywhere from middle-of-the-road to flat-out fast to back-of-the-pack. So I intermittently benchmarked the Xfce engine for an hour, under varying degrees of desktop activity. Everything from lots of different applications open to a completely blank desktop. I couldn't generate consistent results. So, I decided to close down all applications and run a final series of three tests. Presented here are the slowest and fastest times logged for this series.

Look at that. A completion time of 4.63 seconds, well ahead of any other engine. That's best-case though; it can be almost as slow as the Aurora engine, which is notoriously heavy. The DrawingArea and TextView numbers are fairly static in both sets. Everything else tends to vary widely. No idea why. Perhaps the developers have made some changes under the hood between Xfce 4.4 and 4.6?

Note: this post was originally written a few weeks ago, shortly after the Siag Office experiment. Since the draft was written, an Abiword bug has been opened with a different ebuild. Guess I was too slow about finishing up my draft and publishing it. Ah, well. Now you can at least track the progress of the latest Abiword.

After the lengthy but fun entry on working with Siag Office, I've got s'more goodies. It's time to remove more Gnome packages, as I want to have as close to a pure Xfce desktop as possible. Abiword has always been my default word processor, but it has always been burdened with Gnome libraries and other dependencies. The 2.7 development series changes that, removing the need for many Gnome packages.

After reading a comment, I decided to hack up an ebuild for Abiword 2.7.1, the latest developmental release. This is not a stable release; the changes made to the 2.7 series will eventually become the stable 2.8 series. As upstream warns, don't run developmental releases on production servers.

The first step was to copy the latest ebuild, 2.6.8, to my local overlay in /usr/local/portage and renaming it to 2.7.1. The next step was to determine what's changed since 2.6.8.

I took a look through Abiword's ViewVC to see for myself whether or not the pesky Gnome dependencies have been removed or made optional. Seems they have.

I also discovered that there are several totally unnecessary dependencies present in our current ebuilds. Moreover, several configure switches have been renamed from --enable to --with. This means changing the $(use_enable) bits to $(use_with). Also, some switch options have been renamed or removed; there's no more gnomeui or symbol switches, and the printing switch was renamed to print. These were all simple, quick changes to make in the 2.7.1 ebuild. Removing a line here, deleting 3 letters there. Basic stuff.

Another change was getting rid of the xml and expat configure switches, since they're no longer used. While Abiword does use expat, it's already pulled in by libgsf, so we're safe there. Even the internal Abiword documentation notes this in the various configure files, which is why they don't have explicit configure switches any longer.

The longer changes involved studying configure.in to see what it says are the new optional dependencies and adding those as new USE flags within the ebuild. goffice is now optional, and requires an updated version (0.6). So I added an "office" flag to IUSE at the top of the ebuild, and a line to the pkg_setup function:

$(use_with office goffice)

This USE flag can always be renamed later. The important thing is getting the initial functionality in place. It's very easy to add new flags into the Abiword ebuild; it really just requires copying and adjusting the existing USE info.

Once the critical dependencies and versions were sorted out, it was time to update the internals of the ebuild itself.

One of the things that tends to happen when you have a package in the tree for a long time is that cruft from old ebuild versions tends to linger around for a few years. In this case, the ebuild has a few EAPI-1 tidbits like SLOT dependencies, but it also has a lot of leftover baggage from the pre-EAPI days. Part of that includes redundant numbering. There were a lot of specific minimum versions that are completely unnecessary, as the minimum version hasn't existed for a long, long time. So I went through the ebuild and stripped out all the unnecessary versions, leaving just the category/packagename.

Only one package now needs a specific minimum version, gtk+-2.14. Once gtk+-2.12 is removed, then the dependency can be simplified to a SLOT dependency on gtk+:2, to avoid pulling in gtk+-1.x. I did the same SLOT update for the new required version of goffice and for glib-2. All part of the process of updating to the good stuff present in the EAPIs.

With the EAPI-2 update, it's possible to include USE dependencies in ebuilds. This means that you can get rid of hacks like built_with_use, which require a dependency of Abiword (such as Pango) to have been built with the X flag. The whole function to abort the merge if Pango was not built with USE="X" took 4 lines:

if ! built_with_use --missing true x11-libs/pango X; then
eerror "You must rebuild x11-libs/pango with USE='X'"
die "You must rebuild x11-libs/pango with USE='X'"
fi

With EAPI-2, I was able to update the ebuild to this RDEPEND:

x11-libs/pango[X]

Pretty slick, huh?

The next step was to try a test-compile. Run emerge abiword and watch the results.

Hmm, the merge aborts right at the very end. Turns out that the sed scripts carried over from the 2.6.8 ebuild aren't working: they die because the files they worked with no longer exist. Time to figure out where that .desktop file and other stuff have gone.

The first sed script is looking to change some install directories in a nonexistent Makefile. A quick grep through the Makefiles shows that the old change is no longer necessary; nothing has the old incorrect path. This sed script can be commented out.

The second sed script wants to alter the lines in the .desktop file Abiword installs. However, Portage can't find the file to sed, so it aborts the merge. Turns out that Abiword wants to install the file to /usr/share/abiword-2.7/applications/abiword.desktop. That is a nonstandard location, so no wonder Portage can't find it. If it installs here, Abiword won't show up in your desktop menu. The trick is to get Abiword to install its .desktop file to the right location.

Let's review what's happened so far:

1. Create a copy of the latest ebuild to work on.
2. Visit the upstream homepage and changelogs.
3. View the various configure files to determine new dependencies, versions, unnecessary dependencies, optional dependencies, renamed arguments, and the like.
4. Go to work on the ebuild!
a) Hammer out the raw dependency changes.
b) Fix up the USE flags and related functions.
c) Fix up version and SLOT stuff.
5. Give it a test run.
a) Since a couple of minor errors were found, revisit the ebuild. Fix sed scripts.
b) Test it again.

Now Abiword is compiling, installing, and running. The next step is to tidy up the ebuild. This means putting the dependencies and USE flags back into alphabetical order, removing extraneous whitespace, fixing typos present in the original 2.6.8 ebuild, and deleting any unnecessary comments. There's also the small matter of getting the .desktop file to install to the right location . . . call it homework.

The final step (for me) is to upload the ebuild where you can view it. This ebuild is a working template for the 2.8 releases. I plan to keep tracking it, keeping up with the changes. No more forced Gnome dependencies! Yay!

Of course, I was only able to remove two packages: goffice and libgnomeprintui. Something is still pulling in libgnomecups, libgnomeprint, gnome-keyring, gnome-vfs, and several others. The next thing I'll investigate is all the gtk+ Bluetooth apps lying around. I won't rest in my quest to have a totally lightweight, Gnome-free, Xfce laptop.

* * *

This is a follow-up to my Siag Office experiment:

I've discovered that some of Siag's peripheral programs run in spite of the font errors. xedplus, tsiag, gvu, and xfiler all run. They still display the same font errors in the console output, but at least the application itself works. Though I'm not sure that xfiler is working correctly. It pops up a file browser window, but I can't click on an item to open it. I can select it with the mouse, but to open it I have to hit Enter. Annoying. But at least it does go to that folder, or open the document/picture in the appropriate Siag utility.

I still can't get the word processor or spreadsheet working, and those form the core of Siag Office. Any tips?

I was poking through the contents of my world file and USE flags the other day, trying to trim down the number of Gnome dependencies present on my Xfce laptop. Abiword is the application that requires all the Gnome stuff. If only it didn't need deprecated libraries like libgnomeprint, the rest of the Gnome desktop wouldn't get pulled in.

So, I started looking around at alternative word processors and office suites. There's always OpenOffice, but I don't really like using something as slow and bloated as OOo even at the best of times. There are some other office packages available, but they're for Qt/KDE. Or they're made of something really icky, like Java.

And then I found it: Siag Office. This office suite dates back a number of years. It used to be present in Gentoo, actually, but was removed five years ago.

I took a look at the upstream homepage; it still seems to be sporadically developed. Last release was in 2006. I poked around in the documentation, INSTALL, READMEs, and whatnot in the upstream CVS to get a better feel for what's required. Siag mostly relies on little-used X libraries, including old-school Athena widgets and their derivatives. It also has its own expanded widget kit, Mowitz. Siag ain't pretty, though at least it looks better than Motif-based apps. Most importantly, it's reputed to be very fast, needing very few dependencies.

The Portage CVS attic contained outdated ebuilds; the latest Siag release is 3.6.1, and the latest Mowitz release is .3.1. I used the outdated ebuilds as a foundation for creating my own ebuilds. And that's when the trouble, I mean fun, really began.

For starters, the old ebuilds had a lot of cruft leftover from the pre-modular X days. Stuff like virtual/x11, deprecated configure/make functions, unnecessary USE flags . . . even some bad configure switches from when the code did odd things, like --host=${CHOST}. These obvious mistakes required fixing. Then I checked the Getting Siag page to get more of an idea of the current dependencies.

Siag-3.6.1 has build dependencies on gmp, Mowitz, tcl, libXpm, and libXaw. It has optional runtime dependencies for Python, ccmath, and netpbm. The dependency on libXaw may be interchangeable with other Athena widget-compatible libraries. I sent an email upstream to verify this, as comments in the source code give the impression that while Xaw can be used, so can XawM (a variant created by the Siag folks), Xaw3d, and possibly even neXtaw. In my email, I asked specifically about neXtaw, as Mowitz relies on neXtaw. I figure it's best to just use one widget set if possible to give a more unified appearance. Perhaps neXtaw can be used as a drop-in replacement?

Anyway, once the dependencies were updated for the Siag ebuild, it was time to redo the configure/install section. This is actually still a work in progress; I haven't taken the time to really nail down the optional dependencies, add final USE flags, etc. I've been trying to get working ebuilds, not perfect ebuilds. Not yet.

Once the Siag ebuild was working, I moved on to the Mowitz ebuild. This required many of the same fixes that Siag did. The biggest headache, though, was trying to get the Xaw dependency hammered out.

The old version used to be able to use a number of Xaw varieties, same as Siag. However, the latest version seemed to have narrowed it down to either Xaw3d or neXtaw, default is neXtaw. The configure switch --with-xaw3d= should allow for either one, right? The source code comments in the INSTALL file say the same thing. Unfortunately, it doesn't hold up in reality. If neXtaw is not installed, the configure phase will fail, saying it can't find the Xaw implementation (aka neXtaw). I spent an hour throwing Xaw3d and Xaw name/path variants at it before giving in. How ironic that the --with-xaw3d= switch can't actually use Xaw3d. So I let it just run with the default neXtaw, updating the ebuild for this build dependency. Worked just fine. Good thing that neXtaw was never taken out of the Portage tree! The neXtaw ebuild, at least, is up to date.

In my email to the upstream maintainer, I mentioned that the configure and/or documentation is incorrect. Hopefully I'll get a response, but it has been a few years since the code was touched upstream.

Now that I'd hammered out the dependencies for Siag and its two required dependencies (Mowitz and neXtaw), it was time to merge the package. The sourcecode for Siag itself is only abou 1.5MB. That's right, a whole integrated office suite, with word processor, spreadsheet, animation app, file manager, text editor, and previewer . . . less than 2MB. That's quite an accomplishment! Only took a few minutes to compile.

I discovered that Siag is so old that it seems to predate the common .desktop files used to display an application in your program menu, or at least upstream hasn't bundled any. I'll have to write up my own .desktop entries and add in the accompanying installation function into the ebuilds. So I had to use the command line to launch 'em. That's when the biggest issue hit: Siag won't run.

None of the binaries installed can actually run; I have hit upon a rather famous error that dates back to 1998 or so, and has popped up here and there in the intervening decade:

$ siag
Warning: Cannot convert string "-*-helvetica-medium-r-*-*-12-*-*-*-*-*-iso8859-*" to type FontStruct
Warning: Missing charsets in String to FontSet conversion
Panic: can't load any fonts!

I'm not entirely positive what causes this; Google searching has widely disparate bug reports. It's probably something to do with the way pre-modular X did font handling. Siag seems to want to do stuff in certain ways that the old monolithic X did. It may be able to compile against more modern libraries, but whatever it wants to do is too old-school. There's probably some leftover cruft hardcoded somewhere. I just haven't found what, yet.

At least I can see the errors when running the main applications like siag and pw. The animation app, egon, won't even show that much. Just as in the linux.com review, egon simply would not run:

$ egon
Segmentation fault

I'm unable to perform any further diagnosis. I don't have any debug libraries or applications installed on the laptop, and at this point I'm not going to waste any more time on just this one application.

I'll still try to get the rest of Siag running -- there are a few solutions for the runtime font failure, but none of them have worked for me so far. I have not yet given up; I'm still trying to find ways to slim down my laptop, get rid of Gnome dependencies, and lighten up my Xfce environment.

I've put my work-in-progress ebuilds in my devspace. Once again, I should remind you that the Siag ebuild in particular is not yet finished. It'll do the most important things--compile and install Siag--but it's not finished. If you're looking to cut your teeth on some simple ebuild tasks, you're welcome to spend some time in our Gentoo Development Manual and send me a patch. Working with ebuilds really isn't intimidating the way it may appear at first. Mostly, the work just requires time to sort through issues as they turn up. Time, not arcane knowledge of the most secretive inner workings of code.

Also, if you've got any potential solutions to the font startup failure, I'd love to hear from you! This is the last remaining barrier that I know of to getting Siag working. Well, that and setting up Siag to print, as it doesn't have a graphical interface. Instead, Siag needs you to tell it the proper CUPS commandline stuff. Which, again, is just a bit more time and reading the manpage for lpr. Time and reading. That's most of the process. Time, effort, and persistence.

I'm hoping it'll pay off for Siag Office.

Man, it's been awhile since I blogged. I meant to keep putting up a monthly Xfce desktop, share some tips, talk about the latest Gentoo work, etc. And then real life got in the way.

Laptop

I killed yet another piece of hardware when updating my Thinkpad R61i on Friday. I've been sick this whole week, so I had some free time. The laptop hadn't been updated since early February, so there were 176 packages, including the big move to GCC 4.3, which necessitated a system rebuild. Unfortunately, I left the battery in while the system was on AC power for the compiling work. I guess the heat must have built up too much, because the battery got fried. Got the dreaded "battery light flashes amber rapidly" error. So now I only have the extended-life battery, which is heavier and bulkier.

Add that to the list of hardware that compiling Gentoo has killed over the years. The list includes another battery, an external power brick, an internal PSU, two motherboards, two RAM sticks, one RAM slot, two hard drives, and a fan. I'm really on a roll, here.

I still can't find a replacement battery for less than $90, even on eBay, so I may hold off. What I did do was order two more gigs of RAM, to bring the total up to 4GB. Only cost $40 at Amazon, free shipping. Why the RAM? While updating, I ran into the dreaded OOM-killer! The GCC 4.3 compile uses more than the 2GB available and it aborted the merge. This was with nothing else running, too. So be warned: if GCC dies when you move to 4.3, back off on your MAKEOPTS. I had to adjust mine from -j3 to -j2 while compiling GCC and glibc.

Also, while I was updating my whole system, I decided to move the rest of my X/kernel stack to ~arch, as I wanted the new Intel KMS/GEM/UXA hotness. This necessitated using ~arch xf86-video-intel and Mesa, as well as ~arch gentoo-sources, as 2.6.29 has some needed code not present in 2.6.28. I discovered that while this part of the graphical stack was just fine for KMS and fast graphical login, xorg-server-1.5.3 resulted in hard lockups as soon as I opened any windows. I had to grab xorg-server-1.6, libXfont, and randrproto from the X11 overlay in order to get a usable environment. It works great! No more lockups.

So, how much of an improvement is the new stack over what was available in February? I'll let the following numbers speak for themselves. These are the median-high numbers recorded. For the old stack, the numbers varied from 48FPS to 59FPS. For the new stack, from 489FPS to 504FPS. Sync to vblank and vsync have never been enabled.

xorg-server-1.5.3-r1, libdrm-2.4.4, xf86-video-intel-2.6.1, mesa-7.3, gentoo-sources-2.6.27-r8

$ glxgears 
Failed to initialize GEM.  Falling back to classic.
292 frames in 5.0 seconds = 58.272 FPS

xorg-server-1.6, libdrm-2.4.6, xf86-video-intel-2.6.3-r1, mesa-7.4, gentoo-sources-2.6.29-r1

$ glxgears 
2516 frames in 5.0 seconds = 503.174 FPS

Now, the usual caveat about glxgears not being a good benchmarking tool applies here. However, it is useful for relative comparison from one version to the next. And as you can see, it's an order of magnitude better. I notice that stuff is drawn much smoother; there's less flickering especially when shifting Terminal windows around. And I haven't hardly begun to tweak my system for best UXA performance. KMS is nice and smooth; it happens pretty quick in the boot process. No more flickering, just fast loading of SLiM and then Xfce.

My xorg.conf is pretty minimal; the only changes I've specified for the Intel driver section are these:

Option	    "FramebufferCompression" "false"
Option	    "AccelMethod" "UXA"
Option      "Tiling" "false"
Option      "EnablePageFlip" "true"

There are probably some other things I should add for maximum performance, so I'll have to spend several more days hunting for 'em. But out-of-the-box, I'm extremely impressed with the current X stack.

Now all I need is smooth full-screen Flash video performance . . .

Xfce 4.6

The other thing I put on the laptop was Xfce 4.6.1. Decided that as long as my core graphics stack is part ~arch, it wouldn't hurt to try out the latest and greatest Xfce hotness. Now that some outstanding bugs were fixed from 4.6.0 (including a remote security bug, and an icons issue), I thought it'd be worth it. It's pretty slick. The desktop environment is initialized a bit faster than even a fully tweaked 4.4.3.

About the only outstanding issue I have with it is that there is no graphical menu editor. At first, I couldn't get a satisfactory menu even editing the XML file by hand; it was just too different from the old one. So my menu was cluttered with useless toplevel entries, such as Web Browser, File Manager, and so on. Fortunately, Mike pointed me to the solution, so now all offending stuff has been cleared out. Right now my menu works just fine, so I only really need a graphical menu editor for convenience's sake.

I really like 4.6 a lot. The artwork packaged with it is outstanding; I'm using one of the stock backgrounds because it's just that sexy.

Xfce 4.6 is a smash hit, so well done, guys. Very well done. And there's even more good stuff planned for the future. There's a great interview on Planet Xfce with one of the core developers. He discusses some of the exciting stuff coming down the pipe for Thunar, so make sure to read it.

Gentoo

I've been rather quiet on the Gentoo front for the last three months, because life in the outside world has a way of unexpectedly intruding on me. I've been on devaway since February while I try to get stuff into some semblance of order. Sadly, however, I've had to do much more documentation work than I originally scheduled, which keeps cutting into my plans for other areas. I've made a bunch of bugfixes and commits over the last couple of weeks especially. One of the most visible changes is in the Get Gentoo page, putting the automated weekly builds at the top. The handbooks will be updated, too, but they require a tremendous overhaul, so I'll need all the resources of my fellow GDP members to accomplish that. If I can get 'em, that is.

One of the other things I like to do is find some interesting little-known application, determine its usefulness, then hack up an ebuild for it. It's really good practice, actually.

Out of all the applications I've written and updated ebuilds for, the only one that's got me stumped is WordGrinder. I've been in contact with WordGrinder's upstream author, who's a really helpful guy, but I still can't get the ebuild working. While compiling and installing by hand works great, something happens during the compile phase as run by Portage where it violates the sandbox, killing the merge.

Plus, given the pmfile used by the package, it doesn't really respect a user's CFLAGS/CHOST and related configuration. That has to be altered somehow, so I've been trying to work out a similar solution to the one used by our dev-lang/lua ebuilds. No real luck there, but it's not my first priority. What I really want to do is have the merge workin' with Portage. So it's an interesting, informative, occasionally frustrating learning process.

Anyway, take a look at all the stuff in there. I recently reorganized the ebuilds by category/package, instead of dumping everything into a single directory. Some of these have since moved into Portage sometime after I wrote the ebuild for 'em, and some (like Songbird and WordGrinder) are works in progress. I've run into quite a few nifty apps; places like GnomeFiles are excellent resources. Most of the stuff in here I discovered on GnomeFiles, and a lot of the packages on the website are simple enough that it's just a few minutes' work to hack up an ebuild.

I've just discovered two very interesting minimal word processors. They're designed by writers, for writers. They aim to get out of the way and let you just write, with no distractions.

PyRoom

First is PyRoom, which relies only on pygtk. It's really quite minimal and not distracting in the slightest, and easily themeable. I like it a lot. I created an ebuild, available here. Thank goodness for distutils!

WordGrinder

Second is WordGrinder, an even more minimal application that's entirely console-based. Unfortunately, it uses some weird freaky build system called PrimeMover, and it's scary. I asked one of my fellow developers who maintains the Lua package about it, but he's never heard of it. There aren't any eclasses for dealing with any Lua build system.

According to WordGrinder's Readme, the PrimeMover setup should be pretty simple. However, take a look at the pmfile itself. Man, that's ugly. It looks like three hours of judicious sed usage within the ebuild. I can't see any other way to alter it to something sanely installable to /usr.

If anyone has any tips, I'm all ears. I've got a skeleton ebuild for WordGrinder available in my repository, but it really needs fleshing out. So, who's willing to help?

Hardware: graphics shuffle redux

In other news, I had a really fun time getting my ATI X1950 Pro to work (again) with a silent aftermarket cooler (AC Accelero v1 rev2) and the latest bleeding-edge radeon, mesa, and libdrm packages. The hardware mods were fun, but the software . . . well, that's a long story for next time.

Desktop

Oh yes, and this month's Xfce desktop. Token uncluttered version here. All those artists in that Thunar window are amazing. You should be listening to them right now.

icons: Meliae-dust (needed something reddish)
gtk+: Rezlooks L & D
xfwm4: Rezlooks-gtk (yes, it is confusingly named)
background: The Empire (from pixelgirlpresents)

Here are some fast and dirty benchmarks of various gtk+ engines installed on my system, using app-benchmarks/gtkperf-0.40.

Notes on the hardware:

CPU: Athlon 64 X2 4600+
Graphics: nVidia 7600GT, DVI 1440x900 @ 60Hz
RAM: 4GB DDR2-667
Mobo: ASUS M3N78-VM

Notes on the testing environment:

OS: Gentoo Linux (duh)
Kernel: Linux 2.6.27-gentoo-r2 #3 SMP PREEMPT x86_64
nvidia-drivers: 177.82
CFLAGS: -march=athlon64 -O2 -msse3 -fomit-frame-pointer
DE: Xfce 4.4.3
- Xfwm4 with Composite enabled, effects: drop shadows & transparency
- Open applications: 1 instance each of www-client/mozilla-firefox, app-editors/gvim, xfce-extra/terminal
- Cairo: 1.6.4, compiled with glitz support. Not all engines use Cairo, but those that do should benefit from a small speed increase.

The gtk+ engines are all available in Portage. If you're not on Gentoo, look in your distribution's repositories or check here. Custom themes are noted with *. These are personal themes I've made, nothing more than simple color modifications of an existing freely available theme. No additional images are used, so rendering time should not be affected.

All tests were conducted 3 times, using a Test Round setting of 100. I picked the best score of the 3, as I was looking for best-case usage conditions. The results are ranked in order from fastest to slowest.

As you can see, the older engines are generally the fastest, with the more modern Rezlooks engine coming in close behind. Though they're generally not as attractive, the old Mist and Xfce engines turn in very respectable rendering times. The Pixmap engine actually doesn't score too well, coming in at the lower middle of the pack. This is despite many reports I found via Google that suggest it's one of the best-performing engines out there. Not so much; it's about average.

But by far the worst performing engine is Aurora. Now, to be fair, Aurora does many graphical tricks the other engines do not. It came along some time after old engines like Pixmap, Industrial, Mist, and Glider. It features animated scrollbars, gauges, and many possible styles of dropdowns and arrows. In short, it's fully loaded. Yet it also doesn't seem to be optimized; at 15.73 seconds, it's almost twice as slow as the nearest contender, Candido.

The results for the Aurora engine were so dismal that I re-ran gtkperf another 3 rounds, thinking something was amiss. Every result turned in times between 15 and 16 seconds. Clearly, Aurora isn't the engine to use if you're on old hardware.

Conclusion:

Remember, these are down and dirty benchmarks. Cherry-picking the best time out of 3 runs may not be the most fair way of measurement, but since no single result varied more than 2 seconds either way, it can be considered pretty well representative of the engine's overall capabilities.

If you're on less capable hardware, the Mist and Xfce engines will go far. If you want something prettier, stick with Rezlooks. I have several screenshots of Rezlooks-based environments in my devspace. It's quite flexible, and it's still in the top three fastest engines, despite including goodies like subtly animated progress bars and gauges.

But even on my fairly powerful workstation, newer engines like Candido and Aurora were noticeably slower, suggesting they might not be a good fit for older hardware. Clearlooks and Pixmap are middle-of-the-road choices; neither has much of an advantage. It comes down to which engine you think has prettier themes.

Me? I stick with Rezlooks. And occasionally Clearlooks (the Glossy theme makes for a good wintry desktop foundation), and very occasionally I'll find a decent Pixmap theme that's worth modding for my system. Otherwise, it's Rezlooks all the way.

I discovered a really nifty trick the other day, one that makes for a pleasant work environment and that fills the need for a launch area of some kind. It basically eliminates the need for iDesk, too.

While you may be aware that Xfce can draw the usual home, trash, and volume folders directly on the desktop, it can also do things with the icons on the desktop. Like . . . use them as application launchers.

Open up a browser, and drag a .desktop entry from /usr/share/applications onto the desktop. Presto, there's your application launcher. Much larger than the usual miniscule panel icon sizes, too. The downside is that you can't drag items directly from your Xfce menu, but as long as you know where they come from, you can add any launcher you want. A bit of tinkering results in the following:

Who needs a panel, when the desktop launchers, right-click desktop menu, and keyboard commands work just fine? Unless you really need one, of course. It's almost like the ever-popular spartan Openbox + iDesk combination. Xfce distilled to its finest essence. Thank goodness for flexibility.

Over a month since my last entry. Anyway.

The Work

I've been busy churning out the August issue of the Gentoo Monthly Newsletter, as well as a GMN Howto. This is a guide that details the process for creating the GMN, from start to finish. Over the last couple of months, it's gone from a simple 15-line cheat sheet to something a lot more useful for future GMN staff and any interested contributors.

A fair amount of documentation updates for the GDP, too. I was curiously unmotivated most of the month of August, though that's in part because of my health; I spent the first bit of it in the emergency room trying to figure out why my insides were coming apart. Still no idea.

And I've updated my devspace. Lots of changes. Lots of new stuff added and rearranged; I expect I broke some old links, but oh well. All that stuff in misc/ really needed organization.

I also poked aballier to get the new version of Decibel into the tree. Oh yeah. Upgrade to 0.11; it adds album cover art, among other things.

The Apps and the Machine

I've also been hacking up various ebuilds for packages not yet in the tree, such as tint2. This is all for my laptop, which I'm trying to slim down even more. Been removing various applications and making it much more of a minimal Xfce environment. Plus, I like pseudo-transparency. Apps like stalonetray, tint2 (ebuild available here), netwmpager, dzen2, and conky are all curiously appealing. I'm trying to find lightweight, useful, complementary apps to Xfce, in my perpetual quest to create the perfect Xfce environment.

I discovered many of these applications by reading urukrama's blog and kmandla's blog. Both are excellent sources of information on small, light apps, and setting up clean, minimal, functional environments. Quite tasty; be sure to give 'em a read. Especially urukrama's Openbox guide. It's loaded with configuration info, application tips, and much more.

The Environment

I've replaced most of my Xfce panel with stalonetray, conky, and a couple of instances of tint. I just installed dzen, and will be investigating it as a possible replacement for conky. Dzen, however, seems to need a lot of initial time-consuming configuration. And it doesn't seem to do transparency. And it doesn't look like it can even do useful fonts like Verdana.

What I'd really like to do is get rid of all but the start button on the panel, but first I need to find an icon launcher bar that does pseudo-transparency. Why not real transparency? Because compositing with the Intel X3100 graphics chip doesn't seem to be too friendly on my battery life. Actually, I'd be happy if tint had launcher capability now; I hear it's going to be in a future release. I'll just use it when that time comes.

Here's my current desktop: 1 and 2. I've managed to find a nice-looking level of transparency regardless of light or dark background, so everything's fairly clear. Too bad conky can't provide transparency and shade, similar to everything else. That left-hand panel will be going shortly; all I really need are the launchers and the start menu button. Must find a way to slim it down; it takes up too much space. Plus I don't care for vertical panel arrangements.

Since folks are always curious about what's what in any given screenshot:
Left to right: Xfce panel, stalonetray, tint, conky, and tint (just date/time). The wicd applet is anchored in the tray, and a few terminals and gtk+ apps are open in tint.
Background: (1) Liquid Crystal, (2) VSE Grass Flow.
Screen: 14.1", resolution of 1280x800. I notice that when viewing it on my 19" 1440x900 desktop monitor, the fonts look extra-large. Well, they're much smaller on the laptop. The laptop resolution is so high that I have to enlarge things considerably; my eyes aren't what they used to be.

What have I been doing lately?

Patching Drivel, that's what!

I like using Drivel. I never lose a blog entry with this thing, which is more than can be said when Planet Gentoo suddenly crashes when I'm submitting an entry. (Side note: are there any good graphical clients that work with b2evolution? I've yet to find anything in Portage.)

Even though Drivel upstream seems mostly dead, there are still patches to fix problems or add features floating around Bugzilla, so I've been grabbing them and testing, and if they check out, adding them to the ebuild I use in my local overlay.

So far, I've added patches & fixes to my ebuild that fix a memory leak, fix compiling with gtksourceview-2 (Thanks ecatmur! one fewer app that needs 1.x), update the Blogger login URL, and add tag support for LiveJournal. Upstream left a weird version in ltmain.sh; it was giving libtool version mismatch fits. Some judicious sed usage killed it. With extreme prejudice.

Anyway, Drivel's now much more usable. I haven't been through all the open bugs yet, but there's probably another patch or two that can be made presentable. One thing I discovered is that Drivel is using a few deprecated libraries and functions. It's got several deprecated uses of libegg (which has been replaced by equivalent functionality in gtk+), and it still relies on GnomeVFS.

Fortunately, the open bug for libegg has some info on porting to the appropriate gtk+ code, and there's also the guide to Migrating from GnomeVFS to GIO. I'm actually going to give it a shot. It's well documented, and it looks like it's nothing more than an long, intensive search-and-replace session. Right? Right? Guys? Guys?

Even if I fail utterly, well, it'll be fun to try it. Will follow up on this later.

In the meantime, you can get the updated Drivel ebuild and patches here. Just untar it in your ${PORTDIR_OVERLAY}/net-misc/ directory.

* * *

In other news, my new keyboard arrived in the mail a couple of days ago. It's much cleaner, slightly less resonant, and more interesting than the old keyboard. The Delete key got moved up near Backspace (what's the use in that?!?), so some judicious Xmodmap usage shoved the Insert key left, replacing Control_R, and I changed Ins to Del. I need my Del key right next to the arrowpad when working on documents.

The keyboard isn't as quiet as I'd hoped, but it's less squeaky than the old one, and it masses more, so it sponges up some of the resonance when hammering keys. Also, it's got 17 hotkeys, and every single one of them are correctly detected in Linux, no drivers needed (take that, included Windows XP driver CD!). More productivity, whoo!

Gnome's keyboard utility picked up the hotkeys and allowed me to assign them to various standard media key behaviors, but I chose to forgo that and use Xmodmap, since it works for both Gnome and Xfce. Xfce initially couldn't see the hotkeys, but it recognized them after I setup my /etc/X11/Xmodmap. Interestingly, Xfce correctly executes Xmodmap at login with no further setup needed, but Gnome doesn't. I had to go into the Sessions dialog and create an "Xmodmap" startup program entry.

This is weird, because GDM is supposed to execute any Xmodmaps found, whether in the user's home or systemwide in /etc/, and if it finds both, it's supposed to combine 'em. Poke around in /etc/X11, and you'll see that multiple files try to execute Xmodmap. However, GDM and Gnome have utterly failed here. They're weird like that sometimes. Fortunately, Xfce saves the day yet again.

SCALE

It's been a coupla weeks now since SCALE 6x, so it's about time for an after-action report.

My wife and I arrived Friday night after suffering a two-hour delay because of heavy traffic. The 405 was the worst. LA traffic always gives me nightmares.

Saturday morning came far too early, but at least we were already registered. We got there the same time as omp, who'd brought a Windows-using friend along as a booth slave--er, volunteer.

Our booth setup included a giant Gentoo poster, omp's desktop rig, and one (occasionally both) of my laptops, displaying Xfce. It was more popular than the extremely minimal openbox desktop, so HAH! We gave out lots of bribes--snacks--and even more LiveCDs. It's too bad we didn't have flyers, business cards, shirts, or other Gentoo swag this year. Lots of folks were asking for them. At least we gave out snacks'n'luv.

Wireless internet sucked throughout the weekend. Apparently it was the same for everyone. Spotty, minuscule bandwidth, and nameservers couldn't be reached. Made it hard to demo things that needed internet access, such as emerging packages, looking up our homepage, or highlighting documentation.

One of our users, calculus, was around much of the time to help out; was nice to see him at SCALE again this year. And wormo made an incognito appearance, too. To all the users and everyone else who stopped by and asked questions, gave feedback, or just chatted -- thank you. You're terrific. I'm always excited to meet a Gentoo user in person. It's like "Really? you use Gentoo? No way!" We were possibly the least-known distro there (tied with Foresight and Damn Small Linux?), certainly the least commercial one. The other distros were all heavyweights: Ubuntu, Red Hat, Suse, Fedora, etc.

Still, we had lots of traffic. Several people wanted to know what's up with Gentoo in regards to our recent legal status issues, so I provided the news in-person, and that seemed to go over well. Curiously, none of the enterprise-level folks were much interested in our legal status. They pretty much all said the same thing: "We're not worried. All the technical development is still there; nothing's changing." It was only the individual users who had all kinds of worries and needed the explanation. The corporate sector wasn't worried at all: "As long as it's still being developed."

There are plenty of pictures of our booth around the 'net in reviews and photo sites; you just have to look for 'em.

I had a blast at SCALE. I plan to attend next year, too.

ebuilds

Lately I've been poking random ebuilds from the tree, posting updates to Bugzilla, creating new local ebuilds, asking for keywords/stabling, and so on. It's a lot of fun. A fair amount of edgy experimentation, but that's what my new laptop is for. Things like wicd that I'd like to see in the tree, or the latest version of brasero.

burning apps

Speaking of burning software . . . brasero seems to be the only actively developed gtk+-based application. Everything else hasn't had a release in years. Xfburn, gnomebaker, graveman, xcdroast....you name it. That's not good news. Brasero is a good choice for my Gnome desktop workstation, but I wouldn't even think of putting Gnome on my laptop, which is a pure Xfce machine. And yet I hate the idea of putting K3B on my laptop even more, because of the ugly, ugly Qt and kdelibs dependencies.

I went ahead and installed brasero on my laptop anyway, since it's gtk+, and it can work with DVDs. None of the other apps I mentioned support 'em. That added 33 huge Gnome deps, including (ugh) nautilus. The irony? K3B only wanted 18 total packages. Still, it's uglier. That's what counts, right?

So thinking about this sad state of affairs for gtk+-based burning apps got me thinking . . . what would it take to create a new one? Something fast, with minimal dependencies, and gtk-based.

gtk

I've skimmed the gtk tutorial and the reference manual before, but only as a passing curiosity. Today I really took a shot at figuring 'em out. This is where I ran into the cliff known as "C programming."

I'm not a programmer. I can do markup languages, I can do some bash, some javascript, little things like that. But I've never been trained in OOP. Or any kind of programming, except some BASIC in elementary school and college. My degree is in theatre, not computer science!

Still, I'm determined to make what headway I can with these gtk+ guides. I've started to see what does what, and why. And some of the necessary parts of an app. Now I need to find out how to get that button press to do something, like . . . burn a CD. Copy a disc. Save an iso. And so on. For that, I've been poking at the source code for Xfburn, libburn, and brasero. This is all still just a bit over my head, but I'm trying, at least.

I've already partly answered my own question of "Why aren't there more up-to-date gtk+ burning apps available?" because I created a sample task list.

Writing a graphical app is a huge undertaking. What burning backend will be used? cdrtools, cdrkit, libburn/libisofs, dvd+rwtools are all possibilities. Same goes for the media types used in writing audio discs. The app has to handle notification (possibly via dbus), disc drive status/detection, set/get write speed, and a dozen other critical tasks. Oh, and it needs to be translatable (those pesky .po files that take up space), and it really should make use of autotools. What other libraries will it use? Will any of its features be optional compile-time switches? Got to add those too. Where will the project be hosted? What VCS? And so on.

Lots of stuff to do. No wonder brasero's the only active gtk+ burning app. And that's too bad, too. It has a ton of dependencies that folks using Xfce or just a WM don't care to install. I'd like to see the huge gap between "brasero" and "nothing" filled by a low-dependency, fast, capable application. I just don't think I'm up to the task of creating it all by myself.

Right, I'm almost done setting up the Thinkpad.

The keyboard is still taking some getting used to -- I hate having the Fn at the far left, where the Ctrl key should be, and I hate not having the Del/Home/End keys vertically aligned with the right edge of the keyboard. I also keep forgetting I have a working middle mouse button for Firefox. Too used to having to Ctrl-click tabs on the Toshiba. And . . . I love the scroll function on the synaptics touchpad. Love it. The pad itself I don't use much; I'm too used to trackpointers. Plus it's too easy to turn a drag motion into a sudden click. I do like the IBM trackpoint more than my Toshiba; the IBM one is more accurate and has a nicer surface.

Fingerprint use: for the time being, I've uninstalled fprint, and installed thinkfinger instead. Why the switch? Because thinkfinger works out-of-the-box with SLiM, and pam_fprint doesn't work with it at all. If it worked with SLiM, I'd switch back. Also, thinkfinger's enrollment seems to work better. I'm getting far fewer rejected scans. I'd like to file a feature request bug with fprint upstream to get SLiM supported, but its bugtracker mails aren't getting through to my devmail. dsd, you reading this?

I still haven't bothered playing with hdaps yet or finding out why it thinks my disk is unsupported. While on the subject of disks, it occurs to me that I really should have created a /usr/portage partition and formatted it as ReiserFS. ext3 is just too slow for Portage ops.

I at least solved my networking issues by adding a couple of required modules and undoing parallel startup. I also fixed a typo in conf.d/net. I don't plan on using NetworkManager any time soon, as it requires lots of Gnome dependencies. For now, I added a second network block to wpa_supplicant.conf:

network={
        key_mgmt=NONE
        priority=-9999999
}

I haven't tested it yet, but I think this should work for unsecured public access points. Actually, I think this was probably in wpa_supplicant.conf before I deleted everything and added my own config.

My desktop and development environment are just about complete; got my keys imported and my firewall setup and everything. Still haven't setup my system for Bluetooth or audio production yet. Or games.

As promised, I've made my working kernel config available. For all you Intel X3100 users, this may be of use in setting up uvesafb. Also, if you've got an IPW3945 ABG network card, this may be useful if you're using the in-kernel iwl driver. I've enabled the appropriate statistics options to use powerTOP, which is a very nice way to monitor power usage. I get about 2.8 hours doing basic wireless internet, docs work, etc. with my screen almost at full brightness. Not bad. I think I waited too long to get an Ultrabay battery; SCALE 6x is less than a week away!

Speaking of SCALE, I'm going. So I should probably get tickets & registration for me and my wife, yeah? Oh, and a hotel reservation. My new laptop has been such a distraction.

I've discovered a really unusual bug/behavior. I removed alsasound from the boot runlevel, in case I'm running on battery. Now, unless you blacklist them, your sound modules will still get loaded regardless, taking that much more power (even with aggressive soundcard power management enabled.) So what I had been doing was starting and stopping the ALSA initscript once my desktop was loaded. Here's the bug:

Starting and stopping ALSA this way actually kills all GTK theming in Xfce. The decorations revert to GTK defaults, the window colors go to their GTK defaults, the panel becomes ugly, you name it. All I have to do to re-apply the default (pretty) Xfce GTK theme is open one of Xfce's configuration utilities. Any of them. Isn't that bizarre? I have no idea why the hell that happens. Every time I stop ALSA. It's a minor nuisance, I guess.

On thinkpad_acpi and hotkeys:

It's a known bug that the brightness hotkeys don't work, but echoing values directly to /proc does. There won't be a fix for this any time soon, either. I've been in contact with upstream, submitting reports to their database, etc. Still have to go through and test the rest of my hardware (Bluetooth, etc.) and submit another report, but the outlook is not favorable for hotkeys. I still need to find a good program that will recognize the Fn-Home/Fn-End key command for brightness adjustments. xbacklight works, but I need keybinds to call it. Xfce has a built in keybind program, but it can't see Fn key combos. I'll have to find a sane xbindkeys setup (or similar app); there's probably something on ThinkWiki or the Gentoo Forums.

Signing off for now . . . maybe I'll see ya'll at SCALE? Come on by the Gentoo booth! Devs, users, groupies, etc. are all welcome.

Since my last entry, a several important things happened. A number of users and developers chose to engage in a flamewar on the mailing lists. A few developers chose to leave. Many chose to just ignore the problems and focus on their work. Meanwhile, the council has chosen to start doing something about it. Since that last entry ("It's not about choice"), many things have happened. Well, we're Gentoo. We're flexible. We choose when to do things and when to do nothing. We'll adapt, and hopefully we'll weather the storm.

This weekend I chose (there's that word again) to update my Xfce Guide for 4.4, which is now being stabilized. Kudos to the arch teams and the xfce team; you guys rock!

You'll find new package suggestions, new descriptions, tips, links, and even a chapter on migrating from 4.2 to 4.4.

Now, you can choose (that was the last one, I promise) to do many things, but I hope you'll choose (okay, maybe not; I'm such a tease) to read the updated guide and try out Xfce 4.4 yourself.

And now, I choose to go to bed, since the PST to PDT change means the clock just struck 3AM.

Edit: Who's this joker over here? Who chose to write up that kind of wackiness?!?

I added my new Xfce Configuration Guide to our documentation repository tonight. I hope it'll get some of you to try out the wonderful creamy goodness that is Xfce.

* It might take an hour or two to show up; the mirrors have to finish syncing first.

...And part of those new things include:

Time for a status update from my last post!

I finished editing flameeyes' autoepatch documents, just before he sent in his retirement announcement (it's still a ways off, though), and before all his troubles with the stupid BSD-4 licence.

Added random bits and fixes to several docs, including a blurb about branding to the Gnome Guide, prompted this forum topic.

Only the first few items on my TODO list have changed from my previous post:

1) VDR guide updates and autoepatch: Done. Massively overhauled the provided patch (Englishification!), and finished Diego's stuff thus far.
2) Other assigned bugs: Much more progress. I got vivo to send in some patches for some ancient mysql docs bugs just before his retirement, so I closed those old bugs. Love closing old bugs! I've thought of a few more things to do on the pcmciautils migration guide, so I'll get those in and email brix for feedback.
3) Ebuilds: Got some help from Diego on this in exchange for the autoepatch docs. Some progress.
5) SwifT's alternative handbook: added some more tidbits. Ended up using some material I recently added for...

X) Forgot to add this to the last post, but one thing I suddenly decided to do a few days ago was write an Xfce Guide similar to the Gnome/KDE/Fluxbox guides already available. Something randomly clicked in my mind: we've a huge hole in the docs! I love and use Xfce (4.4-rc2, even) on my laptop! I should write something! Originally I'd meant to have it done over the next few months, to coincide with an upstream release, but...

So it took me all day today (since I was sidetracked for a good 7 hours), but I finally cranked out an Xfce Configuration Guide. It's the first all-new standalone guide I've written in awhile. It's much longer than what you'd expect for a guide on a lightweight desktop, because my approach was threefold.

First, I wanted to show how to install & configure a basic, minimal Xfce, and second, I wanted to show how to go beyond that and create a powerful, full-featured desktop environment that still adheres to the Xfce principles: fast, lightweight, configurable, and modular. Finally, I wanted to write a forward-thinking guide. Xfce-4.4 will hit final release sometime in the coming few months, and eventually the stable Portage tree. Therefore, I tried to write it in a way that's immediately accessible and practical to those who will be installing 4.2 (currently stable), as well as requiring minimal rewriting once 4.4 and all its huge changes hit Portage. To that end, I think I've succeeded. I'm hoping that this will be a real resource to all the folks that come to the forums asking "which one?" and "what should I run on this old hardware?"

I did quite a bit of research these subjects, examining not only the applications used on my (quite underpowered) old laptop, but also what the forumites were suggesting. Alas, many of the threads were quite old (2005), and most packages were no longer available -- a good example would be any gtk-1 apps, such as webbrowsers and email clients -- or too heavyweight to warrant consideration. Firefox and firefox-bin are the heaviest packages by far recommended in the guide, and even they run nicely on 128MB memory, a slow hard disk, and abysmal system I/O.

On a final note, my ISP has been completely sucking tonight. Internet availability has been terribly spotty. It's making it impossible to shop online for a headset for Skype. I got my first taste of Skype a few days ago, though it was only listening in to a few of my fellow devs; I had to use IRC to talk. That was pretty cumbersome, but now I feel the pull of Skype...must use it! It's so much more fun to hang out with the guys in #-dev via VoIP.

All right, I finally did it. I went for the eyecandy. I've never set up any thing having to do with composite, transparency, etc., but I figured that since as long as I'm living on the p.masked Xfce edge anyway, I might as well use its built-in compositor. And...it's interesting. I don't particularly like how the panel automatically gets translucent whenever the mouse isn't on it, and it's actually distracting when I have a terminal superimposed on both Firefox and another terminal...I was surprised that the backgrounded Firefox itself becomes clear enough to see the other terminal underneath it.

And yet people dig this stuff? Or maybe they just dig the effects of more nifty compositing window managers like compiz. Anyway, I don't know if I'll stick with it or not. I'm pleased to say that after a little tweaking, it's a minimal resource hit even for my ancient integrated nVidia GeForce2 Go chip. (One of the very first dedicated mobile GPUs, a whole 16MB memory.)

Interestingly, I seem to be running only semi-hardware-accelerated, as I call it. running "glxinfo" gives a segfault, as it can't find the GLX extension to load, despite the visual results. Problem is, I can't enable "AllowGLXWithComposite", as that results in random hard lockups, which is the fault of being forced to use nvidia-legacy-drivers. These older 7xxx drivers are known to have such bugs, but the newer 8xxx drivers don't support my vintage 2001 hardware. Ah, well. At least adding "RenderAccel" to xorg.conf lets me run this stuff with very little noticeable slowdown. I suspect that I am getting hardware accel; it's just confused.

I think I'll bring along this composited laptop to SCALE and show off the wonders of unstable Xfce and the latest eyecandy. Which reminds me, now I need to see about getting all the effects of compiz, but without using that WM or unmerging yet more masked packages. I want to see what else this old graphics hardware is capable of.

...to Xfce4 4.4, that is. I've finally heeded the urgings of my fellow Xfce enthusiasts dostrow, nichoj, et al, and moved my laptop over to the latest Xfce 4.4 prerelease. Sometimes as a developer, you have to live somewhat on the bleeding edge, in this case, a couple of dozen entries in package.unmask. Yow! Hot stuff. The new Xfce has changed considerably since 4.2. It more resembles a traditional desktop environment, but it still retains the speed and ease of use that it had from the older days. That said, some configuration changes have been made. Configuring the panel is a little less intuitive; the same control works for both the icon strip at the bottom and the window list at the top. (So don't just kill the panel process entirely!) No more xftaskbar4 to kill.

There are still a few outstanding bugs, such as missing icons from things like the main configuration window, missing panel plugin icons (none for cpu-freq), and missing icons for mail and webbrowser in the terminal Applications menu. Also missing is the old ability to change the icon spacing in thunar. Though a host of other features have been added, folder views take up way too much space. Need the icons to be spaced about half as far apart as they currently are.

Also, the new battery applet is not nearly as helpful as the old one. For example, even though lm_sensors doesn't work on this laptop whatsoever, the basic thermal zone info from ACPI was parsed by the battstatus applet (don't ask me why, I'm just glad it did). It displayed temperature, battery charge, and an indicator whenever the fan turned on. Handy, right? Well, the fan indicator is still there, but there's no provision for temperature display anymore. WEAK. Grr. I'd downgrade, but the stable version blocks the masked version. Anyone know a fix-it for this?

Speaking of WEAK, my back has taken a sudden turn for the worse over the last couple of days. Earlier this week (i.e. before I started my new schedule on Wednesday), I was almost back to normal. I could walk without limping, at least most of the day. And now...now I'm not doing so hot. Some excrutiating twinges, and constant pain every step. It's a little better than it was yesterday, but I for sure need to get to the doctor's office and get that x-ray done. The doc said it'd take a minimum of six weeks to heal, and at the end of that time, I can say that I'm definitely not recovered. %$^&# sciatica. And at my age, too. I'd hoped to be well by my wife's birthday and Christmas, but doesn't look like that will happen.

Maybe I'll be fully healed in time for SCALE in February?

There were some good comments on my last journal entry, thanks to everyone who responded. I'm happy to say that some of the problems have been dealt with. I've been talking to several developers who are rather likeminded; just check Planet's entries for the last week or so.

Anyway, I've decided to give my trusty ol' lappy das boot, by which I mean "the boot" rather than "the boat."

It's had Gentoo (Jackass! 2005.1, yay for my old project) installed on it since August 31, 2005. And what with one thing or another, it's just been slowing down. It's got a strange partition layout on it, too. A whole unused 10GB ntfs partition (never got around to installing Windows), a smaller Linux test partition, and the main desktop stuff. Rather inefficient usage of the 60GB disk, considering its recent use. The slowness, combined with space issues, and the fact that I haven't updated it since before gcc-4.1.1 went stable on x86 means that I've decided to just reinstall. Why spend a week compiling when everything will likely break if I try to simultaneously migrate to modular Xorg and switch from gcc-3.4, as well as all the crazy kernel/udev/nvidia/madwifi updates?

Time to wipe the disk and move on to something more recent. I've spent today moving /home to my new USB key and dumping it to my AMD64 box. It really highlights the slow-as-molasses USB1.1 on the laptop, as well as the crappy I/0 and slow system bus. I'll be doing some smarter performance tuning this time around, as well as installing only Xfce. I've been running mostly in Gnome because of some weird Xfce/Fluxbox issues, but with only 128MB memory, any and all workloads are just about unbearable.

Of course, the simpler solution would have been to just plug the laptop drive straight into the IDE cables on the AMD64 box for the updates, but unfortunately, the drive uses some weird laptop-only ATA/power combo connector, not the standard IDE connector. Oh well. I don't mind trying out the Installer LiveCD, especially since I'll have nothing to lose.

Guess I have to go re-read all the changes I've been making to the installation handbooks.

First I have to say that Xfce upstream rocks. Benny is quick and responsive to bugs and requests, even though there's so much on his plate from Thunar alone. I asked for a small feature, and it was added in a very short time.

Xfce 4.4 and Thunar are shaping up to be an even better, speedy desktop environment. This is the most impressive release yet.

And on the Gentoo side of things, dostrow pushed out an excellent set of 4.4-beta ebuilds to package.mask within a couple of days of upstream's release. Thunar et al. are a joy to use.

Thanks for all your hard work!
