I seem to be having problems getting my dual monitors to work in Fedora Core 1. The main monitor works fine, but the other one shows colored blocks that flash.... Its mystifying me. Below is a copy of my XF86Config file... maybe someone else can tell me what I'm doing wrong.

*note* most of this was created by the graphical configurator in X... except for the BusID "PCI:1:0:0" on the first entry of the graphics card.

Hi.

Are you actually using two video cards, or are you using two outputs from the same card?

Dave

I In Fedora Core 2 there a tool just for duel monitors but i have not try it.

I'm using one video card that has two outputs. That's why the busid is the same. oh, and after I posted, I downloaded and installed the nvidia drivers off their website. Below are some links to my new changed XF86Config file and the one that I created while in redhat 9 that worked.

Current:

RH9

never mind, I managed to get it working... I needed to have the "screen 1" line on my second video card settings. But thanks for the help anyway.
