Public bug reported:

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.
