Public bug reported:
Binary package hint: gnome-screensaver
While using the Classic Ubuntu Desktop with effects, I've experienced
Xorg freezes when returning to my desktop after the screen has gone
blank.
If I move my mouse or hit the keyboard, the Floating Ubuntu screensaver
will come back up but it is frozen, with no animations.
I can move the mouse and, as I've enabled CTRL-ALT-Backspace, I can
restart X.
The problem DOES NOT appear to happen when using the screensaver by
itself. After looking through my power management settings, it looks
like the problem is partially related to the Power Management being set
to put the display to sleep after a set period of time.
I've changed the power management setting to NEVER put the display to
sleep and have thus far not had the same problem any more.
So, to my untrained eye, it looks like there may be some bad reactions
between power management and the screensaver.
