Linux VNC Remote Control¶

VNC (Virtual Network Computing) is a graphical desktop sharing system based on the Remote Framebuffer (RFB) protocol. It allows users to connect to a remote computer over a network and operate its desktop as if they were sitting in front of it locally.

Configuring the VNC Server on the Board¶

Environment setup

console$ sudo apt update
console$ sudo apt install x11-utils x11vnc -y

Create / change the VNC password

console$ x11vnc -storepasswd

Example:

Note

The password file path $(passwd_path) is /home/kickpi/.vnc/passwd.

kickpi@kickpi:~$ x11vnc -storepasswd
Enter VNC password:
Verify password:
Write password to /home/kickpi/.vnc/passwd?  [y]/n y
Password written to: /home/kickpi/.vnc/passwd

Start the VNC server

console$ export DISPLAY=:0
console$ x11vnc -display :0 -auth /home/kickpi/.Xauthority -rfbport 5900 -rfbauth $(passwd_path)

Example:

kickpi@kickpi:~$ export DISPLAY=:0
kickpi@kickpi:~$ x11vnc -display :0 -auth /home/kickpi/.Xauthority -rfbport 5900 -rfbauth /home/kickpi/.vnc/passwd
