When I close the lid or leave the computer on for a bit the screen goes black and freezes that way. I have tried changing both screen and power settings as well as changing workspaces. Nothing seems to unfreeze or wake-up the computer.
I just installed 11.10 from 11.04, never had this problem with 11.04. Was able to close and open lid just fine.
Considering reinstalling...
Help?
It sounds like you're having trouble with hibernation, which is invoked by closing (and opening) the lid. Look at /var/log/pm-*.log, man pm-hibernate and the files in the pm-utils package (do dpkg -L pm-utils). When my Ubuntu 11.10 hibernates, it also locks the screen (I think this is good). Could your system be trying to lock the screen and getting confused?
