I'm another user affected by this with an 8800GT that has been rock solid stable in prior Ubuntu releases. I'm running the gnome shell fallback mode. The current, current-updates and x-swat repository versions all resulted in random crashes back to the login screen.
I've tried using the noveau driver instead but it increasingly loses its marbles over time. After about 8 hours of uptime it starts flickering random bits of random windows in random places on the screen, and gets progressively worse. It also hangs the X server inputs for a few seconds while doing this. Consequently neither binary nor noveau driver provide a usable desktop. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/973096 Title: Nvidia driver causes xorg crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/973096/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
