FC3 dual head not working
Last modified: 2007-11-30 17:11:01 EST
Description of problem:
Can not get dual head working. Get this warning:
(WW) via: No matching Device section for instance (BusID PCI:1:0:0) found
followed (eventually) by this error:
(EE) Screen 0 deleted because of no matching config section. X then
starts with one monitor.
I have onboard S3 unichrome AGP (via km400), and nvidia GeForce FX
5200 PCI card. I can get either card working individually, but not
both at the same time.
Version-Release number of selected component (if applicable):
I am running x 6.8.2-7. I also tried System-Config-Display-1.0.25-1 to
try and see if that helped. It didn't.

I told the bios to boot the onboard (agp) video first. I then added this line to
the nvidia display entry, so they look like this:
VendorName "Videocard vendor"
BoardName "S3 UniChrome"
VendorName "Videocard Vendor"
BoardName "NVIDIA GeForce FX (generic)"
Option "useint10module" "1"
the useint10module option seems to be the key.
