Public bug reported:
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.
