I have 2 video cards and 3 monitors. Earlier today, I connected my 3rd monitor. Nothing displayed on it and my other 2 screens worked GREAT. While tweaking, I modified my GeForce 8400GS so the "Configuration" was set to "Seperate X Screen" which was the only option available.

enter image description here

Now when I hook up the 3rd monitor I see this (ignore the laptop on the right):

enter image description here The 2 screens show an NVidia logo while the 3rd screen continues to be black. Can someone explain what is going on here?

An X Screen is basically a whole different "instance" of X. In other words, you can run Gnome on one X screen and KDE on another. What happens when you switch X screens (by pressing CTL ALT F[7-12])?

By the way, you may get more help on the forums for this complicated of an issue.
