Xvnc is the Unix VNC server. Applications can display themselves on Xvnc as if it were a normal display, but they will appear on any connected VNC viewers rather than on a physical screen. The VNC protocol uses the TCP/IP ports 5900+N, where N is the display number.
+### Setup
+First of all check if a VNC server is already running or not. Depending on the results you have two options:
+1. Use an existing. (Note the Port/Display Number)
+2. Stop all and start a new VNC server

+```bash
+# Check VNC Server directly, lists available with DISPLAY/PORT
+vncserver -list
+
+# Check for processes:
+ps ux | grep Xvnc
+
+# Kill a VNC Display
+vncserver -kill :[DISPLAY]
+
+# Start a new VNC Server
+vncserver

+3. VNC passwort (`vncpasswd` allows to set this on the server)
The VNC server will automatically start a graphical window manager/desktop environment. Details are stored in `.vnc/xstartup`. Your default configuration will load GNOME, and `.vnc/xstartup` will be something like this:
