Xauthority is not created, and x11vnc fails to start). The following instructions, however, only apply when using Xorg (else. Note: Newer GDM packages ship with Xwayland as the default display server backend. Replace the second ExecStart with the command you run interactively. etc/systemd/system//nf ĮxecStart=/usr/bin/x11vnc -many -display :0 -no6 -rfbport 5901 -auth /var/run/lightdm/root/:0 To run x11vnc when system boots, use a drop-in unit file for rvice. Server_args = -inetd -o /var/log/x11vnc.log -noxdamage -display :0 -auth guessĪfter reloading rvice, X11vnc will start once a client connects to port 5900.

X11vnc can be run using a xinetd service, which only starts X11vnc once a user connects.Ĭreate an xinetd service entry for x11vnc, for example: Where user is the username of the user who is running the X server. # x11vnc -display :0 -auth /home/ user/.Xauthority If that fails, you may have to run instead (as root): Start X $ x11vnc -display :0 -auth ~/.Xauthority Generally, assigning an X authority file requires running x11vnc as root. This is accomplished by using the -auth argument followed by the appropriate file, which will depend on how your X server was started. You may set an X authority file for the VNC server. Also note that /var/log/x11vnc.log needs to be created manually and its ownership needs to match that of the user who will run it.

Note: The password 'PASSWORD' above is not secured anyone who can run ps on the machine will see it. X11vnc -wait 50 -noxdamage -passwd PASSWORD -display :0 -forever -o /var/log/x11vnc.log -bg Then, run the following command, all available options are explained in x11vnc(1).Īnother option is to place the x11vnc command line in a script which is called at login, for example:

You may need to set up X to run headless too. TigerVNC's vncviewer is a recommended client.įirst, start X either by startx or through a display manager. Any VNC viewer should do the job and be compatible with the x11vnc server while not necessarily using all its functionalities. Instead, it shows in real time the existing X11 display, unlike Xvnc, part of TigerVNC, which is an alternative VNC server.Īlso note that x11vnc is not shipped with a client viewer. X11vnc does not create an extra display (or X desktop) for remote control. While it is not developed any longer by its original author Karl Runge, LibVNC and the GitHub community have taken over the development. a display corresponding to a physical monitor, keyboard, and mouse) with any VNC viewer. X11vnc is a VNC server, it allows one to view remotely and interact with real X displays (i.e.
