Description of problem:


With an Asus AT5NM10T-I motherboard (http://www.asus.com/Motherboards/Intel_CPU_on_Board/AT5NM10TI/), X thinks there is a display connected to LVDS when there isn't. This is then used as the primary display when booting the live CD, which means that the VGA display I really do have plugged in will display the background image but nothing else.


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


Fedora 16 RC1, but the symptoms appear with 15 as well (although I have not verified the cause).


How reproducible:


100%


Steps to Reproduce:
1. Boot into live CD
2. ...
3. Profit!
  
Actual results:


A very lice looking background image.


Expected results:


A very nice looking background image, plus the gnome-shell interface.


Additional info:


I worked around the issue by putting this in my xorg.conf then zapping X:

Section "Monitor"
  Identifier "LVDS1"
  Option "Ignore" "true"
EndSection

Here is what my xrandr output looks like VGA1 (really is connected, LVDS1 is not):
