   So, we can infer that the vncserver does not use TCP/IP in it's interaction   
   with X11 clients (as it should use port 6000+ for those). That means that   
   vncserver must use an X11 "Local" connection to service that part of the   
   interaction. "Local" connections are often implemented as a Unix-domain   
   socket (akin to a pipe), and not a network connection.   
      
   This means that ssh X11 forwarding (which works by making the remote server   
   look like it exists on the X11 client system localhost.localnet) won't work   
   here.
