Bug Description
My iMac 21.5 (11,2) has ubuntu 11.10b2 installed, dual boot with Osx Lion. Ubuntu uses the open source ATI drivers At boot the video is good: on main display, correct resolution, reasonable performance. Resuming from sleep the system switches to the external video port (nothing connected) and leaves the main screen unlit. If I plug second monitor onto the external port I can continue after resume. On external screen the X resolution is as if for the main screen (1920x1080); incorrect for external screen (should be 1280x1024). I have no way to relight the main display, except restart.
This issue of wrong display port used to affect ubuntu booting on iMac (see #542660 & #597070) but that problem seems to have been tamed in Oneiric. However not being able to resume without a second screen is a problem, especially since the higher power consumption in Oneiric (+15w compared with OSX) means you would like to sleep when possible. From earlier discussions this seems likely to be something fairly complex in KMS code.

Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.
We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.
If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.
Thank you for your help, we really do appreciate it.
