Bug Description
Binary package hint: xorg
My screen "freezes" from time to time in Natty (didn't happen in Maverick). All I can do is move my cursor. I have tried going into the terminal and restarting the gdm, but
that doesn't do anything.
This occurs at random periods, it can happen multiple times in a day or once in a week.
This started when I installed a clean install of Natty. Maverick and Lucid work fine.
I haven't tested this without Unity.
Pidgin, Dropbox and Chrome(or Firefox, as it happened before I got Chrome too) are the apps that are running during the lockup. Sometimes accompanied by Minecraft (Java + native libraries for JOGL [Java OpenGL]).
Note: I am not sure if it is a X.org issue, although I was told that it probably is on askubuntu.com...
Tried service gdm restart. Gives black screen (some network related text on the 7th screen). Same with killall compiz. Even pskill X...
Okay. So now as I changed sync to VBlank to false and refresh rate to my screen's, instead of being all calm, everything starts flashing as if I was minimising and unminimising windows, commonly with colour issues (such as grey being displayed as a random colour).
Right, so I have output of unity 2>&1 | tee unity.log.

When it happens, log in from the console (ctrl-alt-F1) and run 'killall compiz' and change back to X (ctrl-alt- F7/F8/F9) . Does it revive the session?
