@Torsten Spindler: I'm pretty sure the original bug was a duplicate of bug #488328, which should have been fixed in the 2.6.32-15 kernel, then fixed again in 2.6.32-19. It looks like your bug might be more subtle, so this might not fix it for you.
If it doesn't, there have been a number of similar sounding bugs fixed upstream - the next step in useful testing would be to see if this behaviour still occurs in the Maverick kernel - there's a Lucid backport of the Maverick kernel available in the kernel-team PPA here: https://edge.launchpad.net/~kernel-ppa/+archive/ppa . If it's still reproducible there, testing the drm-intel-next kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/current/ would be the next step. If it's still reproducible there, booting the drm-intel-next kernel appending “drm.debug=0x04” to the kernel boot line (just after “quiet splash”, on the same line) and then attaching dmesg and /var/log/Xorg.0.log after reproducing the problem should give us enough information to start on. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Triaged => Incomplete -- Display error when returning from sleep after docking https://bugs.launchpad.net/bugs/531069 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. _______________________________________________ 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
