Description RussianNeuroMancer 2012-05-10 04:47:56 UTC 
Application: systemsettings (1.0)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

System Setting crash every time for me when I try to open Effects settings. I doesn't get this crash before upgrade to KDE 4.8.3, but this may be unrelated.

The crash can be reproduced every time.

Comment 1 RussianNeuroMancer 2012-05-10 04:52:35 UTC 
This maybe related: I run KWin with KWIN_DIRECT_GL=1.
Comment 2 Jekyll Wu 2012-05-27 20:53:40 UTC 
*** Bug 300722 has been marked as a duplicate of this bug. ***
Comment 3 Thomas Lübking 2012-05-27 21:32:20 UTC 
CompositingPrefs (ie. all OpenGL testing) was dropped from the kcm for 4.9
crash was in fglrx dri code, so yes:  KWIN_DIRECT_GL=1 *is related*
Comment 4 Sergey Mescherin 2012-05-28 07:08:11 UTC 
Um, how can I fix this behaviour? Unfortunately, I don't know what does KWIN_DIRECT_GL=1 mean
Comment 5 Thomas Lübking 2012-05-28 07:19:04 UTC 
That is an environment variable forcing the usage of direct rendering (which was denied for fglrx for being far too crashy in the past) - iff you experience *precisely* this crash (with the same backtrace!) you only have to not export it, direct rendering should be disabled automatically then.
If it still crashes, try exporting LIBGL_ALWAYS_INDIRECT=1 instead (such can be done eg. by scripts in /etc/profile or ~/.kde/env - KWIN_DIRECT_GL is stronger than LIBGL_ALWAYS_INDIRECT so if it shows up with "env | grep KWIN_DIRECT_GL" and you don't find where it's set, you'd have to explicitly disable it by exporting KWIN_DIRECT_GL=0 later on)
Comment 6 Sergey Mescherin 2012-05-28 19:06:43 UTC 
Thank you, LIBGL_ALWAYS_INDIRECT=1 did the trick. Now Desktop Effects settings are opening well. Also, videos now run smoothly.
