Plasma 5 and kdbus testing

Thanks to Mike Pagano who enabled kdbus support in Gentoo kernel sources almost 2 weeks ago. Which gives us the choice to test it. As described in Mikes blog post you will need to enable the use flags kdbus and experimental on sys-kernel/gentoo-sources and kdbus on sys-apps/systemd.

root # echo "sys-kernel/gentoo-sources kdbus experimental" >> /etc/portage/package.use/kdbus

If you are running >=sys-apps/systemd-221 kdbus is already enabled by default otherwise you have to enable it.

root # echo "sys-apps/systemd kdbus" >> /etc/portage/package.use/kdbus

Any packages affected by the change need to be rebuilt.

root # emerge -avuND @world

Enable kdbus option in kernel.

General setup --->
<*> kdbus interprocess communication

Build the kernel, install it and reboot. Now we can check if kdbus is enabled properly. systemd should automatically mask dbus.service and start systemd-bus-proxyd.service instead (Thanks to eliasp for the info).

root # systemctl status dbus
● dbus.service
Loaded: masked (/dev/null)
Active: inactive (dead)

root # systemctl status systemd-bus-proxyd
● systemd-bus-proxyd.service - Legacy D-Bus Protocol Compatibility Daemon
Loaded: loaded (/usr/lib64/systemd/system/systemd-bus-proxyd.service; static; vendor preset: enabled)
Active: active (running) since Fr 2015-07-10 22:42:16 CEST; 16min ago
Main PID: 317 (systemd-bus-pro)
CGroup: /system.slice/systemd-bus-proxyd.service
└─317 /usr/lib/systemd/systemd-bus-proxyd --address=kernel:path=/sys/fs/kdbus/0-system/bus

Plasma 5 starts fine here using sddm as login manager. On Plasma 4 you may be interested in Bug #553460.

Looking forward when Plasma 5 will get user session support.

Have fun!

KDE Plasma 5.3.1 testing

After several month of packaging in kde overlay and almost a month in tree, we have lifted the mask for KDE Plasma 5.3.1 today. If you want to test it out, now some infos how to get it.

For easy transition we provide two new profiles, one for OpenRC and the other for systemd.

root # eselect profile list
[8] default/linux/amd64/13.0/desktop/plasma
[9] default/linux/amd64/13.0/desktop/plasma/systemd

Following example activates the Plasma systemd profile:

root # eselect profile set 9

On stable systems you need to unmask the qt5 use flag:

root # echo "-qt5" >> /etc/portage/profile/use.stable.mask

Any packages affected by the profile change need to be rebuilt:

root # emerge -avuND @world

For stable users, you also need to keyword the required packages. You can let portage handle it with autokeyword feature or just grep the keyword files for KDE Frameworks 5.11 and KDE Plasma 5.3.1 from kde overlay.

Now just install it (this is full Plasma 5, the basic desktop would be kde-plasma/plasma-desktop):

root # emerge -av kde-plasma/plasma-meta

KDM is not supported for Plasma 5 anymore, so if you have installed it kill it with fire. Possible and tested login managers are SDDM and LightDM.

For detailed instructions read the full upgrade guide. Package bugs can be filed to and about the software to

Have fun,

Gentoo’s road to Wayland in KDE

KWin in KDE SC 4.11 will include experimental support for Wayland, as you can read in the official 4.11 Beta 1 announcement:

KWin and Path to Wayland—Intial experimental support for Wayland was added to KWin. KWin also got many OpenGL improvements including support being added for creating an OpenGL 3.1 core context and robustness from using the new functionality provided by the GL_ARB_robustness extension. Numerous KWin optimizations are aimed at reducing CPU and memory overhead in the OpenGL backend. Some desktop effects have been re-written in JavaScript to ease maintenance.

As the Beta 1 is already available in the gentoo kde overlay you may ask what the current state is. You are right it is time to talk about it. I will try to serve you the facts.

Current state

Wayland is already packaged in portage (dev-libs/wayland), thanks to the x11 herd.

johu@elia ~ $ eix -s wayland
[I] dev-libs/wayland
     Available versions:  (~)0.95.0 (~)1.0.6 (~)1.1.0 {doc static-libs}
     Installed versions:  1.1.0(21:54:08 05.06.2013)(-doc -static-libs)
     Description:         Wayland protocol libraries

KWin 4.11 Beta 1 + KWin master (4.8.10 + 9999 ) has already a build option (USE flag) for wayland.

johu@elia ~ $ eix -s kwin
[I] kde-base/kwin
     Available versions:  (4) 4.10.3 (~)4.10.4 **^m[1] [M](~)4.10.80^m[1] (**)9999^m[1]
       {aqua debug gles opengl wayland}
     Installed versions:  9999(4)^m[1](22:14:15 18.06.2013)(gles opengl wayland -aqua -debug)
     Description:         KDE window manager

It builds and links already successfully against it.

johu@elia ~ $ scan kwin

The USE flag is globally masked for stable systems. As a side note, i realy like the stable use mask feature in EAPI 5.

Next steps

1) We need to package the Wayland compositor aka Weston in portage tree, to start a full blown Wayland session.  This task is already in progress (bug #445736), an ebuild is available in the gentoo x11 overlay. Will be finished soon hopefully.

2) Add a wayland build option (USE flag) for the KDE start script (kde-base/startkde). The USE flag will allow us to ship a modified version of it, so that we can tell KWin to use weston/wayland when starting.

So I am realy sure you will be able to play around with Wayland in starting August when KDE SC 4.11.0 is released and hit the portage tree by simply enabling a USE flag. Are you excited? You should!

Have fun!

Disabling semantic-desktop at runtime

Today we bumped  KDE SC 4.11 beta 1 (4.10.80) in the gentoo kde overlay. The semantic-desktop use flag is dropped in >=kde-base/4.10.80, as you may already noticed or read in dilfridges blog post. So if your hardware is not powerful enough or you just don’t want to use the feature you can easily disable it at runtime.

1. Go to the “System Settings” and search for “Desktop Search”

System Settings


2. Uncheck at least the file and email indexer. You can also disable the “Nepomuk Semantic Desktop”.

Desktop Search Settings

Have fun!

Gentoo KDE Team March 2012 meeting

Date: 22 March 2012
Time: 2000 UTC
Place: #gentoo-meetings @freenode

The full meeting log can be found here. Meeting summary is written by dastergon.

1) Roll call

alexxy, dilfridge, johu, mschiff, scarabeus, tampakrap

2) Electing a new team leader


Accepted: dilfridge, johu
Refused: tampakrap, scarabeus

johu -> dilfridge
dilfridge -> johu
tampakrap -> dilfridge
alexxy -> dilfridge
mschiff -> dilfridge
scarabeus -> dilfridge
dilfridge:5 – johu:1
dilfridge is the new KDE team leader with the majority of votes.

3) Dropping RPATH from installed binaries

Add a RPATH entry for every library dir that is not in the system library
directories in ld.conf are not automatically considered as system library
dirs, but only some static list of dirs.
Everyone agreed on RPATH removal. We will introduce a patch with KDE SC 4.8.2
to remove the RPATH and move it to the main tree.

4) Bugs

* Remove hard dep on media-libs/phonon from kde-base/kdelibs
Upstream says “technically you can replace phonon with qt-phonon, but that’s
just stupid because you lose functionality”. Another argument against it, is
that qt-phonon will be removed with qt5. We wont fix the bug and keep phonon as
hard dep. johu will take care of the bug after meeting summary is available.

* Eclass problem with handbook without LINGUAS.
The handbook eclass code is pretty confusing for all in meeting present
members. It was written by reavertm. We decided that we will mail reveartm to
fix handbook eclass code, because he has the most knowledge in it. dilfridge
will take care of contacting him, it’s his first lead task.

* Revise the change “semantic-desktop? -> semantic-desktop=”.
Some packages rely on semantic-desktop capabilities in other ones. tampakrap
is volunteers to take care of the bug.

5) Open floor

* KDE 4.8 stabilization
KWin does not build anymore without opengl support. kde-base/kmail-4.8.1
crashes, but upstream patch can be backported. KDE SC 4.8.1 has tons of
bugfixes, compared to to 4.8.0. The majority votes for KDE 4.8.1 as stable
candidate. johu will prepare stabilization.

* Test failures
creffett brought up dbus-related test failures. johu recommended to get
virtual-dbus eclass running. dilfridge suggested if one or two test fails
or restrict. The problems with virtual-dbus is that you can’t run bash
commands in it’s environment. creffett will be responsible for this.

* New members
Welcome to three new members of the project: creffett, kensington and
dastergon. They are in the process to become gentoo developer and mentored by
tampakrap. creffett and kensington have already open ‘new developer’ bug.
dastergon doesn’t have an open bug yet.

* Comeback
scarabeus re-joined KDE herd. Welcome back!!!

* Reduced work time
mschiff mentioned that he will not have much time for the KDE herd due to
real life priorities, he will be back in may. tampakrap will spent most of his
time for gentoo infra team.

Meeting bits

Yesterday (2012/01/16 20:00 UTC) we had the first Gentoo KDE team meeting this year. The meeting happened in #gentoo-meetings on freenode.

  • Participants: alexxy, dilfridge, jmbsvicetto, johu, mschiff, tampakrap, Thev00d00
  • Agenda
  • Log
  • Lead election is delayed, because 12 months not over
  • We keep kdepim-4.4 in tree as long as it works and provide kdepim-l10n package
  • Kdeenablefinal build feature will be removed today
  • Phonon xine backend will be removed in 15 days
  • We expect no big issues with Qt 4.8,  only kdenlive is not building at the moment
  • eselect boost vs. latest boost is not a Gentoo KDE scope only issue, we will move the discussion to the gentoo-dev mailing list
  • … read log 😛 or wait for the full summary by tampakrap
  • My netbook had a kernel panic while the meeting  :-/
After the meeting i joined the Gentoo Qt team.

CMake picks always the latest boost.

As known as #335108. This is (was) a long term bug in Gentoo KDE scope. The problem is that if you have two or more different boost versions installed, the latest version will be used at build time, regardless which version is (e)selected. Real world example we have boost  1.46.1 and 1.47.0 installed selected the 1.46 slot, the 1.47 slot would be used at build:

$ eselect boost list
Available boost versions:
 [1]   boost-1.46/default *
 [2]   boost-1.47/default

Last night i patched dev-util/cmake-2.8.6 successfully and made the revision bump today in the kde-overlay. So please test =dev-util/cmake-2.8.6-r5, in the case your maintained package is cmake based and needs dev-util/boost at build time. You should test at least with two different boost versions and of course switch between those to check that the selected version is used.

I bumped dev-util/cmake-2.8.7 in the overlay too. The patch is also included in this version.

Start your engines…

From beginner to Gentoo developer

This is my first step in blogging universe. I did that never before and hope my english isn’t to bad. The reason, why i decided to blog from now on, is that i reached the Gentoo developer state. Which gives me the chance to get a central theme to write. My personal goal is at least one post per month, maybe a little bit more if there is something i want to share. For sure the content of this blog won’t be Gentoo only related.

Lets talk about the way i became a Gentoo developer. I get  in touch with Linux in the end  of 2001. The reason why i tried out linux was that i want to discover something new in the computer world. New in the meaning of gain experience. So the first distribution was SuSe linux. Followed up by Debian, Red Hat, Mandrake and some other that i forgot in the meantime. None of these really satisfyed me. In 2003 i heard about a Linux distribution with a very good package manager, a good written installation handbook and all packages build from source. The name of the distrubution was Gentoo, as you may have already guessed. I was really enthusiastic about it, started the installation and felt in love. In the first years of using it, i had tried out other distributions  on seperate partions from time to time. But whenever i have done this, the partion is faster deleted as you can count to three.

While my time as Gentoo user i tried out several window manager/desktop environments. First was Gnome which i had have no longer than 1 week. It was to slow (yeah my former pc was not that good) and i didn’t like the handling at all. So i decided to take a light weight window manager. I tested White-, Black-, Open- and Fluxbox, choosen the last mentioned finally. After several time and new hardware i wanted something new and found XFCE. I liked it very much and sticked with it a long time. A friend convinced me to have a look at KDE 3.5, but after short testing period i had the feeling that XFCE is much better and switched back. With one exception to the other window manager/desktop environments experiences: didn’t unmerge it, because i used a lot of KDE apps from this time on and wanted to give KDE a chance with newer versions. As KDE 4.0 was released, i know that this would be my next desktop environmet and finally switched over with KDE 4.1.

I used IRC all the time, but with KDE my old IRC client XChat felt not so integrated into the desktop, so i searched for a new one and found Quassel. After some time i started to contribute to this opensource project (bug triaging, wiki & code contributions) and got an core account, which gaves me the posibility to idle in several gentoo related channels and of course one them was #gentoo-kde. In July this year i made some contributions to the kde overlay. The Gentoo KDE project lead tampakrap gave me write access to the overlay and asked me very quickly, if I want to become a Gentoo developer and that he would mentor me. I was surprised and honored, so my fast answer was “why not?”. After some weeks i started the ebuild quiz and finished it in September and started with the end quiz in mid October. While the end quiz we decided to switch over to the Gentoo recruiters web application (the usability is not so good at the moment) and  he created the “New Developer” bug. In the start of November all questions were approved by him, so the waiting period for a recruiter started. On 2011-12-01 the Gentoo recruiter hwoarang picked me up. The recruiting process was finished on 2011-12-07, after the third & final review session.  The official mailing list announcement was done  one day later on 2011-12-08.

My special thank goes to my mentor Theo “tampakrap” Chatzimichos. He has done his job as mentor wonderful. I have no comparison to other mentors, but i can say that he is the best :). If he make the offer to mentor you, i can truly say, just do it™. And of course i want to thank  all the members out of the Gentoo KDE project for the support and my recruiter hwoarang for pick me up & recruiting me finally.
