please install also the debug symbols of Mesa. From what we have right now we only see that it crashes in the driver It's by 99.9% chance a dupe of bug #229796 According to a apparently related mozilla bug report[1] it might be because "Mesa versions up to 7.10 cause a BadLength error during the first GLX call when the server GLX version < 1.3." And a post suggests that it has been fixed upstream [2] but i don't know whether that is true and part of Mesa 10.3 (it's in the 7.10 branch and comitted before the 10.3 release at least - theoretically it should be in 10.1) @ Georg: does "glxinfo" segfault for you? (part of "mesa-demos") [1] https://bugzilla.mozilla.org/show_bug.cgi?id=632867 [2] http://cgit.freedesktop.org/mesa/mesa/commit/?id=cbe9fc12a64c3ae89fd1b20e9e165aa4b76293a5 Hi, and sorry for the late answer. Yes, glxinfo segfaults for me. I'll have to rebuild mesa here for debugging symbols, what can take some time (chakra build system needs some time to be set up). Will report back with a new backtrace as soon as I've done that. *sigh* Please try whether mesa from git master works for you. If not, exporting (best globally) LIBGL_ALWAYS_INDIRECT=1 will likely "workaround" this... Hi Thomas, I just recompiled mesa from the git master, and the effects work, the crash is not reproducable any longer. Thanks for the hint. Can be set on "solved" i guess, even though, most people won't have it solved :-). At least a bug which is _really_ "resolved upstream" then ;-) *** Bug 280263 has been marked as a duplicate of this bug. *** *** Bug 303534 has been marked as a duplicate of this bug. *** |
Application: systemsettings (1.0) KDE Platform Version: 4.7.00 (4.7.0) Qt Version: 4.7.3 Operating System: Linux 2.6.39-CHAKRA x86_64 Distribution (Platform): Chakra -- Information about the crash: First of all, KWin started with desktop effects the first time i logged in KDE 4.7.0. It immediately crashed, for the reason that my "graphics drivers probably have a bug". Every time i try to re-enable the desktop effects, this happens. Well, we all know the intel drivers, that's a very likely reason, allthough, with your help, and the help of the intel guys, we probably can get it fixed (ickle said that he wants the bugs occuring for KDE with the intel drivers fixed some time soon, so a little bit backtracing maybe). I installed the debug modules for KDE, probably it helps a little tracking down which effect crashed, where and why. System configuration (quite recent packages there): chakra-linux (testing) KDE 4.7.0 kernel 2.6.39.3 intel-dri 7.10.3 xf86-video-intel 2.15.0 mesa 7.10.3 Maybe somebody of you can give a hint what the Intel guys need to look into. I'm fine doing a bug report in the freedesktop bug tracker for that and/or talk to ickle myself doing the required backtraces for them. Best regards, Georg The crash can be reproduced every time. -- Backtrace: Application: System Settings (systemsettings), signal: Segmentation fault [KCrash Handler] #6 0x00007fcd98c8e8c0 in xcb_glx_query_server_string_string_length () from /usr/lib/libxcb-glx.so.0 #7 0x00007fcd994eeb44 in ??
