[Launchpad Bug Tracker <1035183@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

When I open the my laptop's lid and hit a key/move the mouse a bit to
show the lock screen, the lock screen will sometimes not appear, showing
only a black screen, though the mouse cursor is present and movable. The
machine does not lock up, however, and I can still CTRL-Alt-F1 to kill
compiz/restart the lightdm service.

This happens on both resuming from sleep and from simply reopening the
laptop's lid without having it go to sleep on closing the lid. This does
not appear to occur with gnome-shell. A few days ago, thinking that my
gnome-shell tinkering caused the problem, I reinstalled, and did not
install gnome-shell. The problem still occurred.

When the UI hang happens, though, the compiz process does not get killed
with just a "killall compiz", requiring a "killall -9 compiz" instead.

The laptop is a ThinkPad X200.
