Details here, let me know if you need more info.

How do I start X on the server from a remote machine (via ssh, of course) so
that I can use graphical apps ?
When I google this problem, there is some talk about the DISPLAY variable
not being set. What should it be set to ? How should it be set ?
sshd sets it when you do an ssh -X/-Y. If it isn't getting set then
either ssh isn't seeing suitable environment variables (eg ssh'ing into a
box and forgetting which box you were on when you do the ssh -Y), or it
can be blocked in the sshd config.
