I am having a problem configuring my system for a second display and I'm running out of ideas. I have recently added a second video adapter to the system and I cannot configure the system for dual display. I cannot find any problems with my xorg.conf file (reproduced below). I can edit said file and boot the system onto the other display with no problem, although I do need to switch the primary video controller setting in the system bios for this to work (otherwise, I get a screen full of garbage when X starts).

This is a dual boot system and Windows runs dual headedly with no problem.

The Xorg.log file has a couple of lines which would seem to be important. First, it contains a warning that "I810: No matching Device section for instance (BusID PCI:0:1:0) found." Then, it contains an error saying: "Screen 1 deleted because of no matching config section." There is, however, a Device section for the second video device which reads:

Section "Device"
Identifier "Videocard1"
Driver "i810"
VendorName "Videocard Vendor"
BoardName "Intel 810"
BusID "PCI:0:1:0"
Screen 1
EndSection

It seems as if this block of code is being completely ignored.

If anyone has any experience with this problem, I'd appreciate the input.
