X not working with dual monitors
I'm trying to install Debian 3.0 on my system and run KDE (or any desktop manager for that matter), but it won't start X, KDE, Gnome, whatever. I have two monitors and two graphics cards (nVidia Riva 128 and S3 Trio 64, both old I know). The Riva displays nothing while the Trio has just text. When I try running xdm or gdm, the screen "flashes" all black and the text on the screen but nothing else happens; nothing happens with kdm period. I can't configure XFree86 (or at least I don't think I can) as the screen looks strange when I try to do so. Somehow I've managed to get a message say "No screen detected" (or something like that).
I'm guessing there is a problem with the driver, but I haven't been able to find what driver to use with the card (the Trio). I have the XF86Config file available if needed.
How do I get it to use both monitors (I know the driver for the Riva is available during install)? Also, when I tried to install RedHat 9 to see if my computer just didn't like Debian, the install just kinda died on me.
