VNC Remote Desktop Configuration Guide

1. Install VNC Server​

Use apt to install x11vnc:

sudo apt update
sudo apt install x11vnc

2. Set Access Password​

Create a VNC connection password:

x11vnc -storepasswd

A password file will be generated and saved by default at ~/.vnc/passwd.

3. Test VNC Service​

Start the VNC service:

x11vnc -usepw -display :0
export DISPLAY=:0
x11vnc -auth guess -once -loop -noxdamage -repeat -rfbauth /home/linaro/.vnc/passwd -rfbport 5900 -shared

Manually start the VNC service, set the connection port to 5900. If the port is occupied, you can use another port.

Use MobaXterm or VNC Viewer client to connect. The IP address is the board's LAN IP.

4. Configure Auto Start on Boot​

Create a new vnc.desktop in the ~/.config/autostart/ directory. Example content:

# For example, using the linaro user
mkdir /home/linaro/.config/autostart

# Create the configuration file
vim /home/linaro/.config/autostart/vnc.desktop
[Desktop Entry]

5. Disable Sleep Settings​

To avoid remote connection interruption due to sleep. Disable screensaver and power management:

xset s off
xset -dpms

You can write these commands into ~/.xprofile or startup scripts.
