KWin in KDE SC 4.11 will include experimental support for Wayland, as you can read in the official 4.11 Beta 1 announcement<\/a>:<\/p>\n

KWin and Path to Wayland<\/strong>\u2014Intial 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.<\/p><\/blockquote>\n

As the Beta 1 is already available in the gentoo kde overlay<\/a> 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.<\/p>\n

Current state<\/strong><\/p>\n

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

johu@elia ~ $ eix -s wayland\r\n[I] dev-libs\/wayland\r\n     Available versions:  (~)0.95.0 (~)1.0.6 (~)1.1.0 {doc static-libs}\r\n     Installed versions:  1.1.0(21:54:08 05.06.2013)(-doc -static-libs)\r\n     Homepage:            http:\/\/wayland.freedesktop.org\/\r\n     Description:         Wayland protocol libraries<\/pre>\n
KWin 4.11 Beta 1 + KWin master (4.8.10 + 9999 ) has already a build option (USE flag) for wayland.<\/p>\n

The USE flag is globally masked for stable systems. As a side note, i realy like the stable use mask feature in EAPI 5.<\/p>\n
Next steps<\/strong><\/p>\n
1) We need to package the Wayland compositor aka Weston in portage tree, to start a full blown Wayland session. \u00a0This task is already in progress (bug #445736<\/a>), an ebuild is available in the gentoo x11 overlay<\/a>. Will be finished soon hopefully.<\/p>\n
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<\/a> of it, so that we can tell KWin to use weston\/wayland when starting.<\/p>\n
<\/strong>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!<\/p>\n
Have fun!<\/p>\n
