Apologies for the delay in replying. Here's a more exact description of the problem:
1) Try to use external monitor by plugging it in
2) Monitor gets enabled, but monitor layout is wrong
3) Open gnome-control center to the Displays section
4) Re-arrange monitors, hit "Apply"
5) Screens blink and flash for 5-10s, and end up back in the original (wrong) layout afterwards. I can't tell if it temporarily gets the right resolution or not.

I tried to run apport-collect, but I'm not sure it did anything:
bhearsum@voot ~ % apport-collect 888134

Title:
  automatic detection of plugged in / removed monitor is too aggressive

Status in “gnome-desktop3” package in Ubuntu:
  Incomplete

Bug description:
  I've found that the monitor detection in Ubuntu 11.10 is too aggressive. Sometimes it will get things wrong, and when I try to fix it with the GNOME Control Center, it automatically reverts back to what it thinks is correct. My configuration is as follows:
  * Nouveau Driver
  * GDM
  * Awesome WM

  The problem occurs with both the VGA and DVI ports. I can use xrandr
  to make changes without them getting reverted.
