I am getting just a black screen with a white cursor in VNC Viewer on Windows 10. I have tried many incantations of x11vnc command with Gnome on Ubuntu 17.10, currently:
sudo x11vnc -many -auth /run/user/130/gdm/Xauthority -ncache 10 -noxdamage -usepw -display :0 -forever
The behavior that changed recently, is that before I would get display :0 on 5900 when it was through. Now it says
rfbListenOnTCP6Port: error in bind IPv6 socket: Address already in use
29/12/2017 18:54:59 Autoprobing selected TCP6 port 5901
The VNC desktop is: ares:1
PORT=5901
