Redhat 8 dual head w/ MAtrox G550 & G450


I have a Matrox G550 AGP and a PCI G450 ina Gigabyte board running Redhat 8,..I have both video cards installed and am having a little trouble getting both LCD's to sync and work when x windows is started. Screen 0 initializes but when Screen 1 initializes,..it has alot of horizontal lines distorting the picture. I realize that either card would probably do it by itself but I need to get it working with both cards in there. It looks as if the refresh rate or driver or something is making it flakey,..I wish I knew. I have been to numerous sites and it seems everyone has their little way of editing their XF86Config file. I wanted to post my config file in hopes that some genious out there could pinpoint my error and give a little help. I havent been using Redhat long,..only @ 2 months daily. Im sorry if I have violated any rules by posting this big of a message... =( It was kind of thrown together by using others peoples posts and recommendations,..but something is not right. Thanks for your time.

Which driver?

I'm trying to get it to work on Fedora Core 2, and it's all kinda messed up too. Which driver were you using? The driver and powerdesk utility from the Matrox page didn't really work either.
