As I said in my previous post, for what you are wanting to do,
vncserver is not the right tool. Use x11vnc instead (and also
remove the above copy).

This error is caused by display :0 alreading being in use
by the X server. Again, in your case you don't want to run
vncserver anyway.

If both your VNC server and client are on the same local network,
the following two commands should be all you need to get started:

  1. On the server, from within the X session you want to share:

       x11vnc -forever -shared

  2. Then, on the client:

       vncviewer your-vnc-server:0

You should also take a look at http://www.karlrunge.com/x11vnc/.
That site provides a ton of useful information on how to run
x11vnc in all different kinds of situations.
