Hi all.
I've made a new video about x11vnc. With this you can control your Linux desktop from any other PC/SBC.
It even works for videos and games. Only there's no sound. I use lightdm as display manager. If you use another display manager, change the line "After=lightdm.service" with your display manager.
Here's my video,
To Install
sudo apt install x11vnc
To create a password file
x11vnc -storepasswd
The service script : /lib/systemd/system/x
