I also get the same error:

Fatal Server Error:
no screens found
giving up.
xinit: Connection Reset by Peer (errno 104):   Unable to connect to X Server
xinit: No Such process (errno 3):  Server error
I get this error in all video modes (i.e. KDE, Flux, VESA, etc).

I have heard of several people having problems with my video card due to the fact that is somewhat new. I had hopes that since this is the new version of BackTrack that it may work. Looks like I may have been wrong.

Any help would be appreciated.

BTW, I am booting from a USB key and I have downloaded and added the nvidia.lmz module that is currently posted on the Main Page of the BackTrack Wiki.

Thanks in advance for any help!
