This tutorial was adapted from self.

1. Remove the default Vino server:
sudo apt-get -y remove vino

2. Install x11vnc:
sudo apt-get -y install x11vnc

3. Create the directory for the password file:
sudo mkdir /etc/x11vnc

4. Create the encrypted password file:
sudo x11vnc –storepasswd /etc/x11vnc/vncpwd

You will be asked to enter and verify the password. Then press Y to save the password file.

5. Create the systemd service file for the x11vnc service:
sudo nano /lib/systemd/system/x11vnc.service

Copy/Paste this code into the empty file:

[Unit]
Description=Start x11vnc at startup.
After=multi-user.target

[Service]
Type=simple
ExecStart=/usr/bin/x11vnc -auth guess -forever -noxdamage -repeat -rfbauth /etc/x11vnc/vncpwd -rfbport 5900 -shared

[Install]
WantedBy=multi-user.target

6: Reload the services:
sudo systemctl daemon-reload

7. Enable the x11vnc service at boot time:
sudo systemctl enable x11vnc.service
sudo systemctl start x11vnc.service

Done.
