Public bug reported:

Binary package hint: compiz

In a fresh Natty install, Compiz freezes after the screen goes blank
when I close the laptop lid. However, this ONLY occurs if in Screensaver
settings the option "Lock screen when screensaver is active" is
DISABLED. This is how to trigger it:

1. Untick "Lock screen when screensaver is active" in screensaver preferences dialog.
2. Close laptop lid.
3. Open laptop lid.
4. The screen reappears, all the applications are shown and the mouse cursor moves. However, there is no interaction possible between the user and the applications. The mouse cursor does not change shape when it is hovered over different parts of the applications windows. Everything is unresponsive. I tried to "blindly" enter my password, but this changes nothing.
5. Ctr+Alt+F1 works, and there I can kill compiz (with -9 kill switch) via the command line. Once killed, everything goes back to normal.

If the user enables "Lock screen when screensaver is active" option, the expected behavior is obtained:
1. Tick "Lock screen when screensaver is active" in screensaver preferences dialog.
2. Close laptop lid.
3. Open laptop lid.
4. A dialog asking for password appears. I enter my password and
5. The screen reappears, all the applications are responsive and everything works

This occurs with both Unity and Ubuntu Classic desktop.
