Fwd: Manually, remotely starting X for a remote session. DISPLAY.

[linux guy]

$ ssh me@server
me@server's password:
Last login: Tue Sep 27 20:16:30 2011 from 192.168.1.120
[me@server ~]$ echo $DISPLAY

[me@server ~]$

What should it be set to ?

$ yum list openssh
Loaded plugins: langpacks, presto, refresh-packagekit

openssh.i686                          5.6p1-34.fc15.1

I'm not saying that I know the DISPLAY variable is the problem.  I'm just
providing information.
