One other point relating to the fedora installation on iMac with two monitors. At boot time the login screen is always on the external monitor. During login the kde desktop starts up and the display switches to the internal monitor. I had previously used xrandr to force the display to be only on the internal monitor (external off). The display stays on the internal monitor until resume (from suspend), when the display and desktop then switches back to the external monitor permanently. Without two monitors it is impossible to use suspend and resume.

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.
