Bug Description
Apport thinks this is a GPU hang. It's definitely only happened since I updated to Quantal.
Nothing responds after this happens, I can't switch to other TTYs or back to Unity. Only REISUB does anything.
It's also happened a couple of times upon ejecting a USB drive, although in that case I can still move the mouse.
