Public bug reported: Binary package hint: xorg
After upgrading to natty, the screen saver freezes frequently. Sometimes I can get a terminal with CTL-ALT-Fx, but other times it requires a power cycle to recover. Browsing the log files, I noticed the following 2 messages repeated every 1-2 seconds at the time of the hang: May 5 17:45:17 david-laptop kernel: [73747.356256] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung May 5 17:45:17 david-laptop kernel: [73747.356266] [drm:kick_ring] *ERROR* Kicking stuck wait on render ring Note that I was also having severe problems with Unity so have switched to Classic, which is mostly usable....
