Hi Patrick, Thanks for you quickly answer. Yes, x11vnc was installed on my system. The problem is i not understand the “logic" of vnc connection, so i try to dark… I copy the /etc/systemd/system/vncserver@:1.service to /etc/systemd/system/vncserver@:0.service restart the vnc service and obtain Jul 18 11:17:16 systemd: vncserver@:0.service: control process exited, code=exited status=98 Jul 18 11:17:16 systemd: Failed to start Remote desktop service (VNC). Jul 18 11:17:16 systemd: Unit vncserver@:0.service entered failed state.
