Peter T Hayward, if you have a problem in Fedora, it would be best to
file a report on their bug tracker ->
http://fedoraproject.org/wiki/How_to_file_a_bug_report

Regarding Ubuntu, it would be helpful if you booted into the live
environment of the latest release that currently boots (ex. Saucy,
Raring, or Quantal if either of the prior two didn't work) and checked
for this via http://releases.ubuntu.com/ .

Title:
  ubuntu 11.10b2 resumes on wrong iMac display port

Status in “linux” package in Ubuntu:
  Incomplete

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.
