Bug Description

Binary package hint: xorg

Doing cert testing on a Thinkpad T420 running Natty.

One test executes the following:

xset dpms force off

to test monitor powersaving. This works on the T420, but once you move the mouse, the screen comes back on, but Unity appears completely frozen. There IS still mouse movement, but that is all.

To recover, I had to drop to a shell and manually kill the X process.
