I have 2 ATI rage pro's, AGP and PCI.
I ran xfree86setup and XF86Config looks like it should work, (to me atleast) and X will run on both screens with just the "X -screen screen# ", but when I run GDM or startx both screens change resolutions and go black and the system freezes completely.



Her is my XF86Config file:
