Sometimes if I lock my Ubuntu 11.04 screen, when I try to resume my work.. I see my PC hangs. The black screen does not go off. I can not even see the password prompt screen. I have to restart the PC. The same thing happens with my PC and my friends's PC.
My Sytem
Has anyone come across this problem?

Disable the Screensaver Lock in Ubuntu 11.04 (Natty Narwhal)
Yes I think you are probably experiencing this bug: Natty Screensaver freezes system after some period of inactivity
It is reported in the bug thread that it can be worked around by disabling "Sync to VBlank" in the OpenGL plug-in of CompizConfig Settings Manager (ccsm), but this may not work for everyone.
The bug is marked as a "High" so hopefully it will be fixed soon. Good luck!
I am running Ubuntu 11.04 Natty on a Dell laptop. I was unable to suspend and resume, the resume would wake the computer, but the computer did not respond. My solution was to remove the following packages:
acpi-support
acpid
Now suspend and resume work everytime, including just closing the lid and re-opening. :) Hope it helps.
