--- Comment #6 from Trey Ramsay <tramsay at linux.vnet.ibm.com> ---
There are two displays, one is a integrated display LVDS-1 and the other is
external, VGA-1. Clone mode would be ideal if we can get that to work.

I didn't have any luck with disabling LVDS1 using xrandr
# xrandr --output LVDS1 --off --output VGA1 --preferred
xrandr: cannot find crtc for output VGA1

# xrandr --output LVDS1 --preferred --output VGA1 --off
Had no effect

I was able to get Fedora to come up on external display VGA-1 by disabling
LVDS-1 in the kernel command line.  The integrated display acted strange though
with pixels being illuminated to look like a white fog on the screen.
video=LVDS-1:d

Disabling VGA-1 in the kernel command line had no effect.
