When someone is sitting at their linux machine which is running gnome, 
and if that machine is running at 'init 5', and if they aren't yet 
logged in, they'll have something on their screen called the Greeter. 
If they successfully log in they'll have displayed on their monitor a 
'gnome desktop'.  If they've logged in before, normally gnome (or more 
properly 'gdm') will display those apps which were open that last time 
(at the time they logged out from gnome).  By 'remote display' I mean 
that all of that, beginning with the Greeter, can be seen and used, it 
functions, not on the machine which one is sitting at, at that moment 
called the local machine, but another machine, a remote machine.
