I've since switched back to Arch Linux, but I ran into the same problem. It is a problem with the nvidia drivers. What you can do is install nouveau drivers and see if that helps. This may lead you on the right path http://nouveau.freedesktop.org/wiki/UbuntuPackages
It is unfortunate that this driver made it into 12.04 with such a serious problem. You might want to try downgrading to the 11.10 driver and see if that does any good. But I imagine that it might be dependency hell. -- 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/976383 Title: Periodic lockups or crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/976383/+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
