[Bug 775060] Re: Random GUI "freezes" in Natty (can only move the cursor)

 

** Description changed:

  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.
  
  Note: I am not sure if it is a X.org issue, although I was told that it probably is on askubuntu.com...
- EDIT: 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).
