x11vnc -forever -viewonly

• Launch a VNC server on a specific display and screen (both starting at index zero):

x11vnc -display :{{display}}.{{screen}}

• Launch a VNC server on the third display's default screen:

x11vnc -display :{{2}}

• Launch a VNC server on the first display's second screen:

x11vnc -display :{{0}}.{{1}}
