I'm affected as well. Running 12.04 final, installed from the scratch.
Happens randomly, sometimes multiple times in a few minutes. Tried various NVidia Driver versions to no avail. Log excerpt as follows: May 4 18:14:46 ech3lon kernel: [ 890.010392] Xorg[1480]: segfault at b4f85000 ip b48e1e66 sp bfd629b0 error 7 in nvidia_drv.so[b4809000+706000] May 4 18:14:46 ech3lon gnome-session[2911]: Gdk-WARNING: gnome-session: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.#012 May 4 18:14:46 ech3lon acpid: client 1480[0:0] has disconnected -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/980519 Title: Random log off in Ubuntu 12.04 LT Beta To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/980519/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
