Ubuntu with Xvnc to :1 with no window manager at :0

[Mike Miller]

Is it possible to boot Ubuntu, not load an X window manager and still run 
Xvnc on :1 for remote access?

If I'm actually sitting at the machine, I have to load a window manager to 
be able to see vncviewer, I assume?

Is that how it works?

What I've been doing is using IceWM in Xvnc and exclusively accessing the 
system through that, but I have Gnome running all the time on :0, mostly 
doing nothing but taking up space.
