Public bug reported: 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.
