It's been my experience that if you do not have DISPLAY set before you 
ssh then you will not have it set after you ssh (usually to 
localhost:<n> where n is usually not 0).

BTW don't put the IP address in DISPLAY - just set it to DISPLAY=:0.

BTW2 X is an awful heavy process to run if your aim is merely to run 
ASCII terminals. Instead use mintty (or rxvt) and -e ssh <remote host> 
instead.
