I have experienced this bug a few times after upgrading to Xorg 1.15.0, but no idea about the cause. Sometimes it happens when the computer is locked, sometimes when I'm using it. I'm using up-to-date Arch Linux testing: xorg 1.15.0, xf86-video-intel 2.99.907, kernel 3.12.6, mesa 10.0.1 Intel HD 4000 graphics on i5-3570K. Gnome Shell 3.10.2.1 desktop. I found another report of this on openSUSE forums: http://forums.opensuse.org/english/get-technical-help-here/applications/492955-13-1-gnome-logs-out-itself.html (down currently, but here's a Google cached copy: http://webcache.googleusercontent.com/search?hl=en&num=50&q=cache%3Ahttp%3A%2F%2Fforums.opensuse.org%2Fenglish%2Fget-technical-help-here%2Fapplications%2F492955-13-1-gnome-logs-out-itself.html ) I caught this in gdb, but unfortunatley Arch doesn't ship debug symbols, so gdb "bt full" doesn't provide any more info. Full Xorg.0.log is attached.

You are not using 2.99.907, and 2.21.15 is incompatible with xorg-1.15.
(In reply to comment #2) > You are not using 2.99.907, and 2.21.15 is incompatible with xorg-1.15. The what? I just said in the report that I am using xf86-video-intel 2.99.907. I am pretty sure, because that upgrade fixed Bug 73224. Here's the packge source in Arch: https://projects.archlinux.org/svntogit/packages.git/tree/repos/testing-x86_64/PKGBUILD?h=packages/xf86-video-intel

Created attachment 91761 [details] Xorg.0.log Oh, sorry, I uploaded the wrong log file. Here's the new one with crash in memset().
Better, that looks like bug 73351.
Agreed, the backtrace looks quite similar. I'll mark this as duplicate. *** This bug has been marked as a duplicate of bug 73351 ***
