hope it will minimize the freezes... changing to terminal is not working (Ctrl+Alt+F1), just moving the mouse... connecting through ssh is still working, showing Xorg process taking 100% CPU... -- 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/1033263 Title: Ubuntu 12.04 freezes with nvidia drivers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1033263/+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
