I recently installed F11 x86_64 on my core duo box with an nvidia 7200GS video card
with no problems. However, I performed the installation with the VGA port on the
video card attached to the VGA port on my Dell 1905FP LCD monitor. When I removed
the the VGA cable and connected a DVI cable from the video card to the monitor
the screen went blank. On repeated reboots the screen goes blank just before it
would bring up the X windows login.
I've tried hacking xorg.conf without success.
I'm guessing if I had installed with the DVI connected initially I would be all set but
would prefer not to reinstall everything.
