Re: Multiple Video Cards and Monitors - Dapper

Hi All

I've been trying to get a multiple monitor/video card setup working
on my Dapper box.

I have an nVidia GeForce 2 with SVGA out, and either a 3dfx Voodoo 3
or an SiS Virge card to work with. All of the three cards work fine
when installed and configured individually. Yes I know it's hardly
state of the art hardware, but it's what I've got to work with
currently.

I first attempted Xinerama (one big desktop) but X just crashes. I
took my problem to the Xorg mailing list but got zero response.
<http://marc.info/?l=freedesktop-xorg&m=118218324326044&w=1> If
anybody here has troubleshooting suggestions I'm all ears. (it is
Dapper not Feisty as posted there if that matters)

I've fallen back on the idea of using both cards simultaneously but
separately - i.e. run GDM on the 3dfx and then start a program like
Freevo (or whatever) directly on the nVidia card independent of the
GDM X session. How do I do that? I'm guessing I start X with a
separate xorg.conf file but the syntax to do so and point that X
session at the second card isn't obvious to me. Can someone point me
in the right direction?

Comments appreciated.

When I set up my dualhea system I found it was best to start at a low
resolution such as 640X480 utill I got both working and tehn increase
the resolution untill it stopped working.

Below is the currently working xorg.conf on my Dapper system run Xubuntu
if this of any help.
