My macbook air (intel HD3000 graphics) sometimes logs me out of the gnome session at suspend time. I used to blame gnome (who doesn't), but just noticed that it seems to be an X.org SIGSEGV. Here's the relevant part of my Xorg.0.log.old: [ 13108.565] Backtrace: [ 13108.568] 0: /usr/bin/Xorg (xorg_backtrace+0x36) [0x4652a6] [ 13108.568] 1: /usr/bin/Xorg (0x400000+0x6a289) [0x46a289] [ 13108.568] 2: /lib64/libpthread.so.0 (0x3b61800000+0xefe0) [0x3b6180efe0] [ 13108.568] 3: /usr/bin/Xorg (0x400000+0x5a080) [0x45a080] [ 13108.568] 4: /usr/bin/Xorg (0x400000+0x5a0da) [0x45a0da] [ 13108.568] 5: /usr/bin/Xorg (0x400000+0x10ab21) [0x50ab21] [ 13108.568] 6: /usr/bin/Xorg (0x400000+0x13297c) [0x53297c] [ 13108.568] 7: /usr/bin/Xorg (mieqProcessDeviceEvent+0x191) [0x5518b1] [ 13108.568] 8: /usr/bin/Xorg (mieqProcessInputEvents+0xf8) [0x5519f8] [ 13108.569] 9: /usr/bin/Xorg (ProcessInputEvents+0x9) [0x480809] [ 13108.569] 10: /usr/bin/Xorg (0x400000+0x34102) [0x434102] [ 13108.569] 11: /usr/bin/Xorg (0x400000+0x23485) [0x423485] [ 13108.569] 12: /lib64/libc.so.6 (__libc_start_main+0xf5) [0x3b61421735] [ 13108.569] 13: /usr/bin/Xorg (0x400000+0x2375d) [0x42375d] [ 13108.569] [ 13108.569] Segmentation fault at address 0xc [ 13108.569] Fatal server error: [ 13108.569] Caught signal 11 (Segmentation fault). Server aborting please tell me if there is something sane I can do to make that backtrace more readable. This is with up-to-date Fedora17, I have no idea what X version you call that (your version numbering is insane, and bugzilla has numbers like 7.6 etc, while the Xorg.0.log file contains numbers like 1.12.3)
Possible duplicate of Bug 52496 for which a patch was just submitted to xorg-devel yesterday.

Not sure its related to suspend, nor Bug 52496. Its just happened to me after a resume, but I've also had it minutes after a resume.
