Public bug reported:

Binary package hint: xorg

A second Thinkpad that experiences an X freeze when running the
following command during cert testing:

xset dpms force off

to test monitor powersaving.

The screen goes dark, then moving the mouse turns it back on.  However
at this point, Unity seems to be frozen completely.  The mouse pointer
moves but that is all that works.  The only way to get back to a usable
state was to restart X manually (I dropped to shell and killed X).
