[wellylug] Dual Video cards with X

Greetings.

It is possible, I have it now in my box :)
1. AGP Nvidia RIVA TNT2 / "Total Periferals" monitor (generic piece of
junk
2. S3 Virge (PCI) / Philips 14C (ancient monstrocity, runs 1024
interlaced)

Here is XF86Config for both. Note that Philips is on the left side and
Total Periferals on the Right side of the table.

Also note - in PCI (s3) device section the parameter BusID "PCI:0:8:0" -
the number is determined from command "cat /proc/pci" and finding bus ID
of your second adapter. your hardware configuration may be different.

Also note - modelines probably would not suit your monitor. I'm not
responsible for any damage caused by incorrect modelines. Edit it before
using, according to your hardware.

Have a lot of fun :)

Ilia
