kudos to d1saster on irc, http://quickgit.kde.org/index.php?p=clones%2Fkde-workspace%2Fknechtges%2Fpersonal.git&a=commit&h=c1cbbe012b86fb62f11a5e03dd4432adcde03abe %changelog * Mon Feb 13 2012 Rex Dieter <rdieter> 4.8.0-7 - kwin llvmpipe whitelist (#790142) - powerdevil verbosity++ (kde#289760) Had to backout, due to problems introduced in bug #794835 I'm taking this off F17Target: According to the people who know what they're talking about (ajax, mgraesslin, d1saster), KWin needs more magic from the llvmpipe than gnome-shell, and chances are it'll not be ready in time for Fedora 17. :-( Software rendering will have to stick with XRender or uncomposited mode for now. OK, retested today. with both kwin and kwin_gles kwin was very slow, windows would appear/disappear on a whim, not usable (I think I'll try testing again, with all effects disabled). kwin_gles unfortunately, failed to initialize compositing: $ kwin_gles --replace QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave. OpenGL vendor string: VMware, Inc. OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x300) OpenGL version string: OpenGL ES 2.0 Mesa 8.0.1 OpenGL shading language version string: OpenGL ES GLSL ES 1.0.16 Driver: LLVMpipe GPU class: Unknown OpenGL version: 2.0 GLSL version: 1.0.16 Mesa version: 8.0.1 Linux kernel version: 3.3 Direct rendering: yes Requires strict binding: no GLSL shaders: yes Texture NPOT support: yes kwin(20181): Required support for binding pixmaps to EGLImages not found, disabling compositing kwin(20181): Failed to initialize compositing, compositing disabled kwin(20181): Consult http://techbase.kde.org/Projects/KWin/4.0-release-notes#Setting_up Created attachment 573394 [details]

This was with all kwin compositing effects and features disabled, performance and display of active window was still very poor.
Just a question, any progress/improvement on this with KDE 4.9? Looks like Martin (upstream) officially recommends against this approach, http://blog.martin-graesslin.com/blog/2012/10/to-llvmpipe-or-not/ opting for xrender or non-compositing fallbacks instead. *** Bug 921593 has been marked as a duplicate of this bug. *** |
