I don't see what you mean. It doesn't matter what who you are on the
terminal, what matters is who you are on the server. You'd script the
user on the terminal (root) to login to the server as some user and run
the su command to be whatever user you want on the server.
Hm... did you mean put the GUI login on the terminal and run ssh -X in
the background with the info provided? I guess that would probably be
safer.
