Can the title of the bug be changed to something more descriptive of the problem. It is not just a log-off, the Xserver is actually crashing!
I am experiencing the same problem on a 12.04 Ubuntu installation that was upgraded from previous. Running NVidia 8500GT graphics card. Here is my /var/log/log/Xorg.0.Log.old... [ 69085.061] 3: /usr/lib/i386-linux-gnu/xorg/extra-modules/nvidia_drv.so (0x6767000+0x63d38) [0x67cad38] [ 69085.061] Segmentation fault at address (nil) [ 69085.061] Caught signal 11 (Segmentation fault).
