VNC Remote
Remote login refers to remotely controlling the motherboard through the network. This tutorial only covers VNC remote control methods within a local network.
Users without a display can use the Serial Port Debugging method to run the following commands to configure VNC remote login.
VNC remote control is suitable for systems with a graphical interface. If the system does not have a graphical desktop, we recommend using SSH remote control.
Using VNC (Windows / Linux)
Download VNC Viewer
We need to install VNC Viewer software on the remote device (PC) to control the motherboard.
Go to the RealVNC website to download the VNC Viewer installation package for your system platform.

- Linux
After downloading the Windows version of the *.exe installation package:
- Run the installer
Run the VNC-Viewer-xxx.exe installer as administrator.
- Software language
Select English language and click OK to proceed.
- Start installation
Click Next to start the installation program.
- Accept license
Check the I accept the terms in the License Agreement option and click Next to proceed.
- Installation path
It's recommended to use the default installation path. Click Next to proceed.
- Start installation
Click Install to begin the installation.
- Complete installation
Click Finish to complete the installation.
After downloading the Linux version of the *.deb package, run the following command in the terminal to install VNC Viewer:
sudo dpkg -i VNC-Viewer-xxx.deb
Run VNC Viewer
After installation, open the VNC Viewer software. Users can choose to use VNC Viewer without logging in.
VNC Viewer Interface
Using VNC (Radxa ROCK 4D)
Install VNC Server
Run the following commands in the Radxa ROCK 4D terminal to install the VNC server:
sudo apt update
sudo apt install tigervnc-standalone-server tigervnc-common -y
Set VNC Remote Password
Run the following command in the ROCK 4D terminal to set the VNC remote password:
vncpasswd
The password and confirmation will not be displayed on the screen. When prompted to create a view-only password, choose n (no).
After setting the password, the system will display similar information:
Password:
Verify:
Would you like to enter a view-only password (y/n)? n
A view-only password is not used
Configure VNC Startup File
Edit the ~/.vnc/xstartup file on ROCK 4D:
sudo vi ~/.vnc/xstartup
Modify the contents of the ~/.vnc/xstartup file to:
#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
export XDG_SESSION_TYPE=x11
export DESKTOP_SESSION=plasma
exec startplasma-x11
After editing the ~/.vnc/xstartup file, make it executable:
sudo chmod +x ~/.vnc/xstartup
Start VNC Server
Run the following command in the ROCK 4D terminal to start the VNC server. Use the -localhost no parameter to allow remote access.
vncserver -localhost no
After successful startup, the terminal will display information similar to this, indicating the VNC server's port number:
New Xtigervnc server 'rock-4d-spi:1 (radxa)' on port 5901 for display :1.
Use xtigervncviewer -SecurityTypes VncAuth -passwd /tmp/tigervnc.VQ4DfI/passwd :1 to connect to the VNC server.
Check VNC Server Status
To check the status of the VNC server, run the following command in the ROCK 4D terminal:
vncserver -list
The terminal will display output similar to:
TigerVNC server sessions:
X DISPLAY # RFB PORT # RFB UNIX PATH PROCESS ID # SERVER
1 5901 3283 Xtigervnc
Stop VNC Server
To stop the VNC server, run the following command in the ROCK 4D terminal. The :1 in the command represents the VNC server's display number.
vncserver -kill :1
After stopping the VNC server, the VNC Viewer software will automatically disconnect.
VNC Remote Login
Open the VNC Viewer software on another device and connect to the ROCK 4D using its IP address and port number.
① Enter the ROCK 4D's IP address and port number
② Click Connect to address ··· to connect to ROCK 4D
① Enter the VNC remote password
② Check the Remember password option to save the password for future logins
③ Click OK to connect
Successful VNC Remote Login
