For the purpose of this discussion, the 'server' is the remote system the one
you are ssh-ing to. The 'client' is the one you are ssh-ing from.
1) Before you leave, go to the server and logon at the console so that you
have X running. Make a note of the 'DISPLAY' variable setting. Probably
$ echo $DISPLAY
Do NOT log out.
2) Use SSH to connect to the server as the same user that logged on.
3) Set the DISPLAY variable to the one indicated in step 1.
$ export DISPLAY=:0.0
4) Run the command you want (with nohup and in the background.
$ nohup xterm -sb &
That will run the command so that output is displayed on the server console
and let you log out of your ssh session.
If you want to learn more, you should read up on the xauth command. Also, try
to understand X toolkit basics.
Why do you want to do this anyway?
