I have two ATI 128 Cards. I can get two seperate desktops (you can not drag or copy between them) on two monitors. This one works for KDE. It works ok but freezes frequently. When I boot up in GNOME, my pci screen contains a desktop. My AGP screen is black and when I move my mouse over it becomes an X cursor. I would like it if GNOME had one single desktop that I can drag windows between them. I have a feeling the system will freeze less. Any help is appreciated. Until then I will be playing with it.

Here is my XF86Config:
