Question Monitor resolution trouble under X (S3 Unichrome AGP OnBoard)

Here it is. I have seen this asked about many different items and I cannot seem to get any of them working.
Fedora Linux Core 3 - Xwindows System
I have an S3 Unichrome built on AGP Graphics Adapter... (VIA KN400 Chipset) 32MB Shared
I also have an S3 ViRGE/GX2 4MB PCI Card.

I tried Dual Heading and it worked.

Here is my problem. No matter what I do, I cannot get the Main Monitor (the S3 Unichrome) to display more than what seems to be 640x480. I can only get it to change the bit depth.

I have tried editing the "xorg.conf" file many times. No go. I have tried all of the X Windows configuration utilities. No Go. When I have Dual Head up I can change the old 4MB PCI card just fine. (Kinda' Tempted to run with it and shut down the onboard AGP... hehehe)

here is my "xorg.conf" minus all of the BS (# BlahBlahBlah)

I really do appreciate whatever anyone can do to help me out. I'm not a dummy (I don't think.. *grin*) and I have gone through forum after forum. Googled, and ASKed and whatever else... 5 hours later I am posting. So I'm not posting without having tried first.

By The Way... one time I did my "xorg.conf" file wrong and setup came up for X... funny thing... the SETUP was in 1024x768!!!!!!!!!

Go figure!

Thanks a bunch people!!!

Why do you repeat the Subsection "Display" section?

I checked your file and it looks almost letter for letter like my XF86Config (which works - I'm on Rh9 with a Winfast A350XT TDG with the latest Nvidia driver) except for the repeated SubSection Display...

I did delete the repetitive DISPLAY listings going on a hunch and it did not work. So far the only way to work the S3 UniChrome is to go to VGA mode.

Oh-Well for me.

I'll learn as time goes on. This guy doesn't give up too easy. Maybe I'll just slap a known, well working, video card in the thing.
