Public bug reported:

Doing certification testing on the Lenovo W510.  During testing, I
closed the lid and re-opened.  The system suspended.  I pressed the
power button to resume and once it was awake again, the desktop was
present but not usable.

I can move the pointer around freely, but the pointer never changes from
the Text pointer to the arrow as it moves over various areas of hte
desktop.  Clicks to windows or launcher icons or panel icons do not
produce any results.  Right clicks do not produce any context menus.

There is no way out of this. Because CTRL-ALT-BKSP was decided to be
such a bad thing, a user in this position has only two options.  Reboot,
or drop to a console and kill X.

I reset X by dropping to a console and sending it a SIGHUP.
