For me (on a Thinkpad x201), it appears that this commit causes the hang on resume:
drm/i915: Use ACPI OpRegion to determine lid status I'm using the current Natty kernel (v2.6.38-8.42) plus the drm/i915 changes from the Ubuntu git repo for 2.6.38-9 and -10, plus the patches in the branch Timo referred to above, EXCEPT for the above patch and those which don't apply cleanly without it: drm/i915: Move the lvds OpRegion lid detection code to panel and reuse for eDP drm/i915/lvds: Always return connected in the absence of better information Suspend/resume, all combinations of internal panel and external VGA, and Fn+F7 are now all working. -- 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/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/745112/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
