I'm hoping I have the right list here with my help question....

I have Fedora 2 and I've installed it on my Presario 2100 laptop. I'm trying to get the video out to my CRT to work but it only will mirror the laptop screen during non-X video output. The second X comes on, my NEC MultiSync 97F dies. Below is my xorg.conf file:

The laptop only has one video chip, and, I don't believe it will be
possible set up duel heads.

Most laptop BIOS's and videos are pretty limited for power and size
constraints.

Thanks for the response, but I forgot to say that dual monitors work fine on the XP side (I can even tell it to turn off the laptop screen and go 1600x1200 on the CRT), and it works on the Linux side during non-X (text-based boot scrolling, command line before startx, etc.) work. I can't see this as anything but an X issue.
