Comment 28 for bug 809956

The problem happened again this morning.

Am now running the kernel 2.6.38-11-generic #50-Ubuntu

This time the screen would go black when I put the mouse over the launcher, but if I moved the mouse away while screen was black everything would recover ok. However as soon as I put the mouse over the launcher or the global menu, the screen would lockup again. Eventually the whole system locked up and couldn't get to the command line via Ctr-Alt-F1.

There is another trace that happened after the GPU lockup that seemed to be related to the system lockup.
