Dual LCD's?

Can anyone tell me how I can set up dual LCD's on Linux? I am using Gnome and have Nvidia drivers inatalled.

Both LCD's are identical & and am wondering if both can be connected to a AGP card that has dual output? The card has DVI and Analog connections and both LCD's support both.

Anyone know how I would go about hooking this up?

Doesn't look like it is a dual head card. Just able to connect to different types of monitors. If both ports are used then it will only display the same on both.

So I will need to use like another PCI card or will that even work?

Yes adding a pci video card will due. Or use a duel head video card.

If the card has dual outputs and dual-head capability (every Ti4600 I've seen does), then you can connect two monitors. Basically you just need another monitor section, another device section (one with "Screen 0", one with "Screen 1"), and add another line to the server layout. This should all be documented in the Nvidia README.

Here is what looks to be the relevant parts of my xorg.conf that I'm running my GF4 Ti 4600 with dual monitors. I'm running two CRTs at 1024x768 each by default. The desktop is a 2048x768 desktop spread over two monitors. When I play a game at 1024x768 or lower, with previous nvidia drivers, the left monitor would turn off, with the game on the right monitor, but with the newer drivers, both monitors display the same image. You might also just try using the nvidia config generator that comes with the drivers on their webpage.
