apt-get install vnc4server
Config for xfce to start with vncserver
vi /etc/vnc/xstartup //add in the following: startxfce4
Start VNC Session
The first time a user goes "vncserver" from the cli, they will be asked for a password. This will be saved in ~/.vnc/passwd There will also be other log files in ~/.vnc/ Note, you can edit on a per user basis xstartup, however in the Config above, I added startxfce4 to the global file.
