Public bug reported: Binary package hint: xserver-xorg-video-intel
Since my upgrade to Ubuntu 11.04 with Unity, I sometimes have a GPU hung error in which case it seems the screen is 'dead' and does not show anything anymore. Here the error: May 26 13:02:42 ubuntu-server kernel: [22293.856048] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung May 26 13:02:42 ubuntu-server kernel: [22293.856069] [drm:kick_ring] *ERROR* Kicking stuck wait on render ring The system remains trying for every while to get control over the GPU, but without any effect. The lines above are repeated every couple of seconds in the logfile. If I do a Remote shell to my ubuntu machine it seems that the machine works without problems except for the videocard. If I do a reboot, everything works fine immediately again (including the videocard). In Windows7 (my system is dualboot) I have never experienced any problem with my videocard. I have a Intel® Desktop Board D945GSEJT motherboard with an ATOM 1.6 GHz processor on it and with an onboard i915 GPU chip. In an earlier version of Ubuntu I have had a problem with the videocard as well, after an upgrade to that version a strange problem occurred which caused my Xwindows to freeze completely. This was eventually fixed with upgrading to a higher version of the Linux kernel, but it seems related to not be able to get control over the GPU (that is at least what I remember). Info of my motherboard: http://www.intel.com/products/desktop/motherboards/D945GSEJT/D945GSEJT-overview.htm It has the latest available version of the BIOS inside. I have no clue how to continue and to get this issue solved. If I would have known on forehand I would not have upgraded to 11.04, because I want a stable system. Does anyone have any suggestions? Might be related to: #690201 and to #732304 but I don't think it is exactly the same. ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/792698 Title: GPU hung ERROR => nothing is displayed on screen anymore. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
