If DISPLAY is not set by ssh, then the tunnel hasn't been created.
You'll never need to set it manually.

Look at:
sshd config on the server side -- is XForwarding allowed?
ssh client config -- is XForwarding turned on?

To manually turn on X forwarding, try:

ssh -X user at remote

and check for the existence of $DISPLAY.

Oh, if the server side does not have minimal Xlibs and apps, then X
forwarding won't work. Doesn't sound like that's the problem, but it
could be.

ssh -vvv turns on debugging info -- often useful.
