[LUGSB] Remote desktop from SINC site?

[Michael]

As the subject explains, I'd like to be able to control my desktop, on the  
computer in dorm room, from a SINC site computer. I've been able to SSH in  
to my box
and that's all worked fine, but I haven't been able to use X-session
forwarding. For example, when I attempt to start my (graphical, not lynx)
web browser, I get a message along the lines of "display not found". Does
this indicate that I have not setup SSH or X correctly, or is there a
(artificial) limitation of the SINC site computers/network? If it's the
later, is there a solution anyone could suggest to me that they've gotten
working, such as VNC or RDP?
