Picture of corrupted screen

Hello,

When booting Ubuntu Trusty daily the desktop and all further screens are
corrupt. The loading screen displays correctly. The mouse/pointer still works
and displays correctly. Switching to a tty also works and displays correctly.

Booting Ubuntu Precise (live) works correctly.

Regards,
Tim
