Alan Pope , as per http://www.asus.com/Motherboards/P5N32E_SLI/HelpDesk_Download/ an update to your computer's buggy and outdated BIOS is available (1903). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Once the BIOS is updated, and the information above is provided, then please mark this report Status New. Thank you for your understanding. ** Tags removed: 12.04 ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/949958 Title: Full screen video corruption on nvidia betwen lightdm and desktop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/949958/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
