It keeps giving me a Failed to start x11vnc.service: Unit x11vnc.service has a bad unit file setting. I've checked re-checked... the file is exactly as is yours. Driving me nyts...

Thank you very much. What i not understand is that before you choosed lightdm the current display manager was gdm3 (the GNOME default display manager) and after you changed it to lightdm and after the reboot nothing changed. What happens here? Why lightdm and what happens if we let it to gdm3? could x11vnc not handle it?

Is there a way to change the port when x11vnc boots?
I tried sudo x11vnc -rfbport but this only works while I'm connected via vnc and stops working the second I disconnect.
I also tried setting up -rfbport in the .service file, but this broke vnc all together for some reason. Maybe I misplaced it?
I put it in the line with "ExecStart=/usr/bin/x11vnc -forever -display :0 -auth guess -passwd my-password -rfbport
Maybe you can help me. Thank you for the video!
