cursor arrow clear, but nothing else

[Dougie]

I got up this morning after leaving my screen locked all night to find the 
screen image all scrambled up. I could move around my cursor arrow and it 
was clear as day, but the rest of my screen wasn't. It didn't matter if I 
was logged back in or running the screensaver. The only thing I could do is 
press Ctrl+Alt+Backspace which after a few moments brought me to a normal 
login screen. When I logged back in everything was fine. 
This is the only time Ubuntu has done this to me. Anybody seen this before? 
What is the deal?
