Can't start an X Window

[David Abrahams]

Hi,

I just added a new account on a RedHat linux box.  Everything seems
to be working with X when I login remotely with ssh -X, i.e.

   xterm

brings up a new xterminal.  I can't get emacs (20.7.1 on this system)
to run in a new X window, though (it just comes up in the current
terminal), and there's no diagnostic output to tell me what's going
on.  Can anyone help?

TIA,
