A VNC is a graphical desktop sharing system to access another computer remotely. When installed on a server with Ubuntu 24.04, it provides desktop access to the server.
Requirements:
Virtualization server with Ubuntu installed.
Root access via SSH.
1. Update the current package list and upgrade it:
sudo apt update
sudo apt upgrade
2. Install the selected desktop environment.
To install XFCE, enter:
sudo apt install xfce4 xfce4-goodies
3. Install and configure Virtual Network Computing (VNC)
Use the following command to install TightVNC:
apt install -y tightvncserver
Set the password:
vncpasswd
Start the VNC service:
vncserver
With the service startup, a default configuration directory at ~/.vnc/, with the file configuration xstartup is created.
We need to stop the VNC service to modify the configuration file:
vncserver -kill :1
nano ~/.vnc/xstartup
Replace the content with the following lines to start the XFCE desktop:
#!/bin/sh
xrdb $HOME/.Xresources
startxfce4 &
Make the
xstartupfile executable:
chmod +x ~/.vnc/xstartup
Use the following commands to restart the desktop process.
vncserver -kill :1
vncserver
3. Connect to the VNC Server
