I have this bug at boot, mangled screen with partial purple colouring, message 'Input not Supported' from the monitor bouncing around the screen. When boot finishes, all is well. I think it's okay on shutdown, I only shutdown occassionally and don't hang around to watch. Ubuntu 12.04 (fresh install on bespoke desktop built on Gigabyte M68M-S2P Motherboard (Nvidia nForce 680s intergrated graphics).
