First I must say that I'm not sure if I selected the right component for the bug report, since I'm not sure where the problem is. I selectec lib/GLX as it is what stands out from backtrace in xorg.0.log.old file. Here is what happens: Sometimes when I use Alt+Tab to switch to another window X just crashes and I'm returned to KDM login screen. Ususally I have to use the laptop for a couple of hours before this happens. It appears that it happens sooner if I use more OpenGL apps. I can't see much of the info anywhere when this happens. nothing in dmesg or elsewhere, just the backtrace from xorg.0.log.old. Is there anything I can do for a more usefull report? My system is: eMachines E640G laptop with integrated ATI Mobility Radeon 5470 graphics. Software: Mesa, libdrm, xf86-video-ati from git, Xorg server 1.10.1, KDE SC 4.6.2, Linux kernel 2.6.39-rc4

I finally had the opportunity to connect over SSH to run Xorg in debug and this is what I got when it crashed: Program received signal SIGSEGV, Segmentation fault. 0x0000000004434930 in ??

I believe this was fixed by 6a433b67ca15fd1ea58334e607f867554f227451 which was in 1.10.1.901 and later. commit 6a433b67ca15fd1ea58334e607f867554f227451 Author: Adam Jackson <ajax@redhat.com> Date: Mon Mar 28 12:30:09 2011 -0400 glx: Fix lifetime tracking for pixmaps GLX pixmaps take a reference on the underlying pixmap; X and GLX pixmap IDs can be destroyed in either order with no error. Only windows need to be tracked under both XIDs. Fixes piglit/glx-pixmap-life. Reviewed-by: Michel Dänzer <michel@daenzer.net> Signed-off-by: Adam Jackson <ajax@redhat.com>
