Description of problem:
X doesn't remember the appropriate resolution settings, and does not know what
to do when started without a monitor, so default to an "ugly" resolution.

Version-Release number of selected component (if applicable):
All version since F7, including those available in Centos 5.x

How reproducible:
Every time

Steps to Reproduce:
1. Turn on computer
2. Boot in to Fedora or Centos
3. Ensure monitor is off before X starts

Actual results:
X chooses some horrible resolution.

Expected results:
X uses last working resolution

Additional info:
1. Neither of the major desktop OSes seem to have this problem
2. There is no obvious solution (obvious meaning can't solve without
understanding  the problem)
3. This is happening on every install of Fedora or Centos where a monitor may
be off, including KVM setups
4. I can't imaging how this looks/seems to new users, I can't imagine that it
is good
5. Even for people like myself who know to Ctrl+Alt+Backspace it is very
annoying to always have to remember to put on my monitor, or have to restart X
6. I have set the severity to medium, but I've been enduring this since F7
hoping that it will be fixed eventually, but it hasn't
