Created attachment 19183 [details] Xorg.0.log.old - the zipped X server log containing the crashed session Hi, enabling KDE4 desktop effects crash my X server based on Intel video drivers. After applying the setting "Enable desktop effects" from the systemsettings tool Xorg crashes and returns me to the KDM logon. After that, logon does no longer work, Xorg crashes immediately again. After disabling the above setting launching systemsettings from another window manager, as twm, and restarting KDE 4.1.1+, all works as before, without desktop effects. Hardware: - Intel 865 G I use the latest OpenSUSE 11.0 (x86) repositories for: - X.org - xorg 7.4 (with XAA acceleration), Intel video driver 2.4.97, Mesa 7.2 final - Qt - Qt 4.4.2 - KDE 4 stable desktop Let me know if I forgot something to tell here. Is this subject to the XAA acceleration, which you don't support any longer?

Yes, we only support EXA. So please use EXA (though it may not help in this case) by removing below line in xorg.conf: Option "AccelMethod" "XAA"
Created attachment 19192 [details] Xorg.0.log.old - the zipped X server log containing the crashed session (using EXA) Ok, I repeated this with the EXA acceleration, commenting out the XAA line in xorg.conf. The behaviour is the same, the Xorg Server crashes. The backtrace can be seen in the latest Xorg.0.log.old.

What is 'KDE4 desktop effects'? Compiz?
(In reply to comment #8) > What is 'KDE4 desktop effects'? Compiz? No, but it's built-in into the KWin windows manager - KWin Composite. It offers similar features as Compiz like window transparency, transition effects (windows can zoom open or closed, or explode as you minimize them, etc.). See http://www.kde.org/announcements/4.0/desktop.php - Section "KWin - The KDE window manager" - "Desktop Effects".
Initially, I reported this to KDE, see: http://bugs.kde.org/show_bug.cgi?id=171641 Another fact: On another hardware (Asus P5B, Intel Core 2 Duo E6300, NVidia GeForce 7 with native NVidia drivers), this feature works absolutely stable and performant.

The crash issue is fixed in mesa (master: b4bf9acc32ac8693b1fdf80f351523a468ba6bd1, mesa_7_2_branch:48c29b60a899877c76d643b9cd06d5277cd97b9c). But it always gets a black screen. And it also gets a black screen with VESA video driver.

If not, would you mind to include it so that I can verify whether this fixes the reported problem, please? Thank you
Thanks, René. I'll apply the patch to our Mesa package. The 'always gets a black screen' for any OpenGL application (Intel 855/865) is still remaining. It's tracked in Bug #17963.
@Stefan: Thanks, I checked it. In fact, that was the mentioned patch fixed this crash for me in OpenSUSE 11.0. BTW: Instead of the crash, I get now the "Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values. Check your X configuration. You may also consider changing advanced options, especially changing the compositing type." message from the KDE4 systemsettings tool. I still don't know why, because in the xorg.conf there seems to be compositing enabled, but that's another issue, not to be discussed in this thread. Thanks for the feedback and the fix.
