How do I set up Xfce to operate remotely?

I thought this was a command shell.  Like telnet only secure.
Am I missing something?

I have tried nomachine, but found it a mess.  When I exit,
one of my processors is (on the server) is max'ed out.

Tried using vncserver.  But, got the 100 % on one of my
processors on exit.  And twm really sucks.  If I run Xfce, it
spreads itself all over the place -- a real mess.

I have not had much luck with all this.

Is there a way just to run "X" windows with Xfce
as the GUI remotely?  I would love it if my first
screen was my gdm greeter.

Many thanks,
