Description of problem:

I have a laptop (HP Compaq 8510p) and a 24" monitor (HP LP2465). When I connect the monitor to the DVI port on my laptop the monitor does not light up.



Version-Release number of selected component (if applicable):

$ rpm -q xorg-x11-drv-ati
xorg-x11-drv-ati-6.13.0-0.11.20091119git437113124.fc12.x86_64

How reproducible:

Everytime.

Steps to Reproduce:
1. Install F12
2. Connect DVI monitor to laptop
3. Boot
  
Actual results:

Laptop monitor lights up.
DVI monitor *doesn't* light up.
(GDM puts login prompt on DVI monitor regardless. Makes hard to log in!)


Expected results:

Laptop and DVI monitor to light up.


Additional info:

Connecting secondary monitor to VGA output on laptop works.
