I have a Dell C840 laptop with fedora core 2 installed and fully patched.
The system has BIOS version A13 on it.
I have a Dell 1900FP flat panel external monitor connected to the system. I need to be able to display the same data on both my laptop monitor and the external monitor. I've tried muddling with the xorg.conf extensively over the past 2 days, and the best I can do is get the display to come up on the external monitor at 1600x1200 and on my laptop screen at 640x480.

Ideally, I'd like the display on my laptop to come up at 1600x1200 and the display on the external monitor to come up at 1280x1024 (most projectors don't go higher than that).

If I can't get that to work, I'd be happy with 1280x1024 on both montiors.....

Here is my xorg.conf:
