multiple video cards question


Hi,

I am a total Linux newbie. In fact I just installed Linux (Red Hat 8.0) for the first time a couple days ago. Everything seems to be working fine, including the dual booting between Windows and Linux, I just need help configuring my video cards.

I have two video cards: GeForce 2 MX (AGP) and GeForce 4 (PCI). Currently my primary card is the GeForce 2, but the one the Linux automatically detects is the GeForce 4, so I manually set it to the GeForce 2. I can change the primary to the GeForce 4 in my bios if that will help.

Anyway, I am wanting to set up dual monitor in Linux but don't know how. I searched on this forum and found some stuff about Xinerama, but the how-to guides for that assume that you know how to do basic video card configuration stuff, which I don't. (I told you, I am a total Linux newbie.)

So, can someone please tell me what my options are and how to accomplish them, or at least point me in the right direction.

Thanks!

Ok, I've made some progress (I think). I've been editing the XF86Config file to use two video cards and two monitors. I changed the GeForce 4 (PCI) card to be the default card in the bios since it is the better card and all, but I don't really think that matters. Anyway, my second screen is still blank but I can move the mouse off the left side of the first screen like it is going over to the other screen. I just can't see anything on the other screen. Can anyone help? Here's my XF86Config if that helps.
