Sorry if this has been answered before, I've searched and didn't find anything that helped me.

I've been playing with Backtrack 2 final live CD on my desktop for a while now. I decided to install it instead of using the live version all of the time. The live install went smoothly. I set up lilo to dual boot backtrack with winXP and all seemed good.

Well, backtrack boots to the console. I can login as root, change my password, etc. I can xconfig without problem but when I try to startx I start running into problems.

It's odd because it runs fine on live.

The error I get is

Fatal server error:
AddScreen/ScreenInit failed for driver 0

XIO: fatal io error 104 (Connection reset by peer) on X server ":0.0"
after o requests (0 known processed) with 0 events remaining.

I have an ATI Radeon x800.
