I have a problem on my kubuntu 12.04 installation using the backports repository. I'm using the fglrx-driver which was suggested by jockey, which is version 8.96.7 with Opengl 3.3.11627. I previously ran kde 4.10 without having any problems. After receiving the 4.11 Update my Desktop effects (Opengl) won't run anymore, telling me that it is not able to use Opengl (1.2,2.0,3.1). If I work without those effects I get periodically get lot of fractals inside the current window when I change size or position of the window. I can remove them by sliding over with the mouse. As intermediate solution I installed gnome shell and parts of unity. Wether Mutter nor Compiz does seem to have a problem with the fglrx driver due 3d is working as expected here. So I would say there is an incompatibility in Kwin with my driver? gllrxinfo says: andre@andre-Precision-T1500:~$ fglrxinfo display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: ATI FirePro 2260 OpenGL version string: 3.3.11627 Compatibility Profile Context I know that I could make use of the fglrx-update packages but my graphics card is AFAIK only supported to Version 8.98, so I am currently not willing to update, because I cannot break my work-System ( http://ubuntuforums.org/showthread.php?t=2075779 ). Any suggestions what I can do? Thanks Reproducible: Always Steps to Reproduce: 1. Install Kubuntu 12.04 with latest updates 2. Having my Graphics card ATI FirePro 2260 3. Use jockey suggested fglrx-driver which is 8.96.7 4. Add KDE backports PPA https://launchpad.net/~kubuntu-ppa/+archive/backports 5. Update KDE to Version 4.11.0 Actual Results: Not beeing able to use Composit-Type OpenGL anymore ( whilst in kde 4.10 in ran perfectly, so as Mutter or Compiz are doing currently ) it always falls back to Xrender. Expected Results: Worked as in 4.10 release, Including Desktop-Effects which are frequently used by my workflow
Created attachment 81875 [details] This is the (german) message which comes up when I try to switch composite type to opengl
you're likely running into bug #323553 and friends. Please run "kwin --replace" from konsole (ensure to have kwin debug output active) and compare the output about failing to initialize OpenGL1 Why (a very basic) indirect context (and OpenGL1) setup does not work, is atm. not clear. -> Just enforce direct rendering (and OpenGL2) but be aware that it was initially blacklisted for random crashes. There's also been reports that after "aticonfig --initial" things started to "mystically" work again, but there's no guarantee on that.
Hi Thomas, i could not find some options for debug or verbose mode for kwin-replace, but after doing kwin-replace commandline gave me some output. After kwin-replace I tried the following (just to compare with my output) 1. In system Settings Composite: Opengl version 2.0 native 2. In system Settings Composite: Opengl version 2.0 raster 3. Same with Opengl 3.1 in same order Heres what I got: andre@andre-Precision-T1500:~$ kwin --replace QDBusConnection: session D-Bus connection created before QCoreApplication.

I will consider the magic aticonfig --initial solution and will report about it. As said upgrading driver seems to be not good for me due ati is not supporting my card after version 8.98
Ok I tried the aticonfig --initial thing but it did not change anything for my situation :-(
ok, is same bug. export KWIN_DIRECT_GL=1 export KWIN_COMPOSE=O2 kwin --replace & if that works, put the two exports into an executable #!/bin/sh in ~/.kde/env *** This bug has been marked as a duplicate of bug 323527 ***
I can confirm, that this did the trick. But putting this into an executable in kde/env is not working wether with or without kwin --replace command. I will figure out a way that will automatically set the variables needed tomorrow and will report about it. Thanks for yourmquick help :-)
Try "kcmshell4 autostart" (gui to add env scripts) Notice that the script has to be executable and of course contain a usable shebang ------- snip ------------ #!/bin/sh export export KWIN_DIRECT_GL=1 export KWIN_COMPOSE=O2 # do *not* kwin --replace here! ------- /snip ------------ chmod +x /path/to/script
copy 'n paste is evil. ------- snip ------------ #!/bin/sh export KWIN_DIRECT_GL=1 export KWIN_COMPOSE=O2 # do *not* kwin --replace here! ------- /snip ------------
:-) Of course I made it executable (This is why I called it an executable) and gave it a shebang line. First I just put in the export commands and if this was not working, I added th kwin-replace. I consider putting those variables in a global scope or in rc.local. Currently I cannot try this due I'm not at work. I will report tommorow what I achieved. Best
