multiple gdm

[Stephen Adler <adler stephenadler com>]

Guys,

I'm not sure if this is the right mailing list to ask this question so
forgive if I miss-posted...

I have a system with two video cards, quadro K2200 and a K620 and the
nvidia propriatary driver will not configure a single desktop (X server)
using both cards. It will configure two separate X servers or X
displays, one for each card. So I thought maybe I could run two versions
of gdm, one for each X server or X display (I'm not sure the terminology
here.) :0.0 and :0.1 would be the -display syntax to use. This way I
could have two separate sessions a bit like a KVM switch expect I'd have
two monitors with one keyboard and mouse, and I would move my mouse over
from one monitor to another to switch from one gnome session to another.

so... how would I configure gdm to run on two X displays or servers?

Thanks!

Steve.
