4850x2 - catalyst - disable - 3 monitors?

[Shannonb1]

I have a 4850x2, 3 monitors, and now I cant see the third monitor. In the driver catalyst it says that the third monitor is UNKNOWN. I see this as xfire is enabled therefore cutting the 3rd monitor off. Does anyone know how to disable xfire so I can see the third monitor?

I have a similar dual ati card 3 monitor system. I left my xorg.conf and instructions as to how I got it in post #9 on this thread.

try a new xorg.conf generated by

sudo aticonfig --adapter=all --initial

From your xorg.conf it appears to me that only one card is active.

should look more like
