I know that this question has been asked several times, however I haven't found anything that is quite what I am looking for. I have two video cards, on NVidia GeForce 2 (AGP), and one ATI Rage 128 (PCI) card. I would like to have multiple monitors going at the same time. Included is my XF86Config file. More than likely, I am missing something, please help!
