I have a new HP xw4200 workstaion with an Nvidia nvs 280 PCI vidoe card. This card allows you to connect 2 monitors to the one card (it has a split adapter, not seperate VGA and DVI outputs). SuSE 9.2 did not detect the two monitors, only one. After a scratch around the net I found some xorg.conf files and have feebly modified my file so in YAST I now see two monitors, however one is the mirror of the other. When I go into YAST>Hardware>Graphics Card and Monitor>MultiHead>Screen Layout, I only see one monitor in there, when I query the monitor ID both my monitors come out as <Screen (0)>. The hardware works fine under Windoze but I don't wnat to run it (use Vmware alot and it runs heaps better on Linux) but I really need two monitors going. Below is my xorg.conf file:

I had to add my second monitor. click monitor configure and add you second monitor... I think it's that simple, it was for me. Although, any time I click on "screen layout" my system goes out to lunch, freezes and the hard drive seems very very busy, but never comes back.

Landis.

Yeah been through all that. It doesn't pick up the second monitor automatically. Think I might try another card.

Well, I found my answer. DualHead is not supported in Linux, by Matrox on the G400 DH.
Here is the release notes from Matrox themselves:

Thanks for the effort,
Landis.
