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