I'm afraid I didn't explain myself very well; sorry about that. I
think a better way for me to put it might be that I believe that Xvnc
*is* an Xserver, so there is no reason for it to contact *another*
Xserver. I think (I haven't tried this yet) that if U want the
vncviewer to display what U see on the console, U have to start
Xvncserver *instead* of xdm. Only the Enterprise version of uses
native authentication; the Free version doesn't even use encryption,
which is why U'll read about people sending the RFB packets through an
SSH tunnel (see http://www.realvnc.com/vnc/features.html). If U use
Xvncserver as your Xserver, however, authentication by VNC doesn't
matter, because your system will do the authentication as the Xserver.
Authentication is not encryption, however, so U should still send the
connection through a tunnel, or it will be visible to anybody who takes
the trouble to look.
Of course, YMMV; as I warned in my previous post, I'm an X *user*, not
a guru. :) I use x86-64 Debian at home and Cygwin X on WinXP at work,
but I don't get a lot of time to play with my Linux box. The only
thing that I have done so far is to fix the screen resolutions available
(so that I'm not stuck with 640x480) by copying xorg.conf from Knoppix;
I couldn't even tell U why that works, because I haven't had time to
investigate.

So I gather that U have done this before?
