Description of problem: When enabling OpenGL desktop effects in KDE on my machine with an Intel GM965 graphics adapter, the X server SIGSEGVs. The restarted X server shows a garbled screen after login (when kwin starts). Version-Release number of selected component (if applicable): kernel-2.6.29.6-213.fc11.i586 mesa-dri-drivers-7.6-0.1.fc11.i586 mesa-libGL-7.6-0.1.fc11.i586 mesa-libGLU-7.6-0.1.fc11.i586 xorg-x11-server-Xorg-1.6.1.901-1.fc11.i586 xorg-x11-server-common-1.6.1.901-1.fc11.i586 How reproducible: Always. Steps to Reproduce: 1. Run systemsettings (KDE4). 2. Click "Desktop effects". 3. Click on the "Advanced" tab and make sure that "OpenGL" is selected as "Compositing type". 4. On the "General tab", select "Enable desktop effects". 5. Click "Apply". Actual results: The X server crashes and leaves this in its logfile: Backtrace: 0: /usr/bin/X(xorg_backtrace+0x3b) [0x812d07b] 1: /usr/bin/X(xf86SigHandler+0x9e) [0x80c061e] 2: [0x197400] 3: /usr/lib/dri/i965_dri.so(intelDestroyContext+0x139) [0x44b309] 4: /usr/lib/dri/i965_dri.so [0x443a66] 5: /usr/lib/xorg/modules/extensions//libglx.so [0x26be19] 6: /usr/lib/xorg/modules/extensions//libglx.so(__glXFreeContext+0x91) [0x260ff1] 7: /usr/lib/xorg/modules/extensions//libglx.so [0x25ebeb] 8: /usr/lib/xorg/modules/extensions//libglx.so [0x25ee05] 9: /usr/lib/xorg/modules/extensions//libglx.so [0x261340] 10: /usr/bin/X(Dispatch+0x347) [0x80864d7] 11: /usr/bin/X(main+0x395) [0x806baf5] 12: /lib/libc.so.6(__libc_start_main+0xe6) [0x66aa66] 13: /usr/bin/X [0x806afa1] Fatal server error: Caught signal 11. Server aborting When logging in again, the screen is garbled, but desktop effects seem to work (windows become transparent when you move them, although it's not that easy to see with the garbled screen). Expected results: Compositing should work. Additional info: * OpenGL desktop effects worked in Fedora 10 (but I experienced bug #486695). * Sometimes parts of the screen appear garbled also when not using desktop effects, e.g. when pulling up certain Qt applications.
I'm seeing this after the upgrade to mesa-7.6: Backtrace: 0: /usr/bin/Xorg(xorg_backtrace+0x26) [0x4e8c86] 1: /usr/bin/Xorg(xf86SigHandler+0x6f) [0x47d9df] 2: /lib64/libc.so.6 [0x3ebdc33370] 3: /usr/lib64/dri/i965_dri.so(intelDestroyContext+0x116) [0x7fa4da73a0a2] 4: /usr/lib64/dri/i965_dri.so [0x7fa4da732886] 5: /usr/lib64/xorg/modules/extensions//libglx.so [0x7fa4dbf06d79] 6: /usr/lib64/xorg/modules/extensions//libglx.so(__glXFreeContext+0x6c) [0x7fa4dbefc74c] 7: /usr/lib64/xorg/modules/extensions//libglx.so [0x7fa4dbefcacb] 8: /usr/bin/Xorg(CallCallbacks+0x4c) [0x44b5bc] 9: /usr/bin/Xorg(CloseDownClient+0x58) [0x441e68] 10: /usr/bin/Xorg(Dispatch+0x210) [0x446fa0] 11: /usr/bin/Xorg(main+0x3b5) [0x42d145] 12: /lib64/libc.so.6(__libc_start_main+0xfd) [0x3ebdc1ea2d] 13: /usr/bin/Xorg [0x42c5c9] Fatal server error: Caught signal 11.

In fact, could this be a dupe of bug #512693?
In Fedora 11 package is named xorg-x11-drv-intel. Changing bugs apropriately.
