+++ This bug was initially created as a clone of Bug #680082 +++ Description of problem: While doing this test day: https://fedoraproject.org/wiki/Test_Day:2011-02-24_Intel https://fedoraproject.org/wiki/QA:Testcase_intelvideo_3D_tuxracer I discovered problems when running etracer. Before running this command, I had two displays attached (internal laptop LCD and external display through docking station). After running etracer, external display is turned off and internal LCD displays gnome shell in "expo" mode (bug 680082 concerns that problem). After quitting etracer, there is about 50% chance that Xserver crashes and restarts. I have also reproduces this behaviour with openarena. I believe this could be the same for most fullscreen OpenGL apps (games). Version-Release number of selected component (if applicable): xorg-x11-drv-intel-2.14.0-2.fc15.x86_64 xorg-x11-server-Xorg-1.9.99.1-4.20101201.fc15.x86_64 How reproducible: always Steps to Reproduce: 1. have two displays 2. run etracer 4. quit etracer 5. see Xserver crash (repeat if it doesn't crash) Expected results: Xserver doesn't crash. --- Additional comment from kparal on 2011-02-24 05:22:04 EST --- Created attachment 480706 [details] rpm -qa output --- Additional comment from kparal on 2011-02-24 05:23:41 EST --- Created attachment 480708 [details] dmesg --- Additional comment from kparal on 2011-02-24 05:23:56 EST --- Created attachment 480709 [details] messages --- Additional comment from kparal on 2011-02-24 05:24:11 EST --- Created attachment 480711 [details] Xorg.0.log

My assumption is - it's the same bug as my problem I could see when I quit Xsession: (gdb) bt #0 0x0000000000000000 in ?? () #1 0x00007fd95594fb31 in DrawableGone (glxPriv=0x3362d60, xid=<optimized out>) at glxext.c:171 #2 0x000000000044c4a5 in FreeClientResources (client=0x1372ca0) at resource.c:854 #3 0x000000000044c558 in FreeAllResources () at resource.c:871 #4 0x0000000000422d9c in main (argc=<optimized out>, argv=0x7fff2250b368, envp=<optimized out>) at main.c:301 (gdb) up #1 0x00007fd95594fb31 in DrawableGone (glxPriv=0x3362d60, xid=<optimized out>) at glxext.c:171 171 glxPriv->destroy(glxPriv); (gdb) print *glxPriv $1 = {destroy = 0, swapBuffers = 0, copySubBuffer = 0, waitX = 0x1, waitGL = 0x39527225, pDraw = 0x3440590, drawId = 0, type = 0, config = 0x0, target = 0, format = 0, eventMask = 1} Obviously 'destroy' pointer is NULL - so either the structure is improperly initialized - or damaged by some overwrite - I assume valgrind would show more details.
Note - as mutter is now opengl app - every user of gnome3 is affected.
Assuming it's duplication of Bug 674464.
