James Lownie, could you please capture the xorg backtrace following https://help.ubuntu.com/community/DebuggingSystemCrash ? The log must contain the word "backtrace" in order to be helpful.
** Description changed: - This is the same as bug 1161102 - (https://bugs.launchpad.net/bugs/1161102). - The initial symptoms are that Ubuntu will suddenly log me out of the session. This happens when using Thunderbird Mail and TrueCombat Elite. Looking at ~/.xsession-errors shows the error message "XIO: fatal IO error 11 (Resource temporarily unavailable) on X server" just before the crash. Running Glxgears will also cause this error message to be displayed. - It seems to be a problem that affects both NVIDIA and ATI cards, judging - by what I saw when googling the error message. - - My card is a Radeon X850 PRO AGP, I'm running Ubuntu 13.10. - ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: xorg 1:7.7+1ubuntu6 ProcVersionSignature: Ubuntu 3.11.0-15.25-generic 3.11.10 Uname: Linux 3.11.0-15-generic i686 .tmp.unity.support.test.0: - + ApportVersion: 2.12.5-0ubuntu2.2 Architecture: i386 CompizPlugins: [core,bailer,detection,composite,opengl,compiztoolbox,decor,resize,regex,snap,animation,imgpng,unitymtgrabhandles,vpswitch,mousepoll,gnomecompat,place,grid,move,expo,workarounds,ezoom,wall,session,fade,scale,unityshell] CompositorRunning: None Date: Mon Feb 17 08:08:23 2014 DistUpgraded: 2014-02-08 17:38:59,393 DEBUG enabling apt cron job DistroCodename: saucy DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: - Advanced Micro Devices, Inc.
