Great, yes there have been a number of fixes to sandybridge in the drm- intel-fixes kernel. This targets the 3.3 kernel and so since Ubuntu precise targets 3.2, the fixes may not get into Precise automatically. Possibly Eugeni upstream will backport the fixes to 3.2, or else the Ubuntu kernel team may cherrypick some/all of the sandybridge fixes.
Moving to the kernel since last comment indicates a fix is available in the drm-intel-fixes kernel branch. They can follow up if they need to have you do git bisection to identify the patches, or if they just want to bulk import all the sandybridge fixes (which would probably make more sense). ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete => Triaged ** Package changed: xserver-xorg-video-intel (Ubuntu) => linux (Ubuntu) ** Tags added: kernel-handoff-graphics -- 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/924851 Title: [snb-m-gt2] Primary display is blank if external display is connected at boot-up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/924851/+subscriptions _______________________________________________ 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
