How To Install VNC Server on Ubuntu 20.04 – TecAdmin

May 8, 2021

Introduction

Welcome to TecAdmin's comprehensive guide on how to install VNC Server on your Ubuntu 20.04 machine. With VNC Server, you can access your Ubuntu desktop remotely and perform tasks conveniently from anywhere in the world.

Prerequisites

Before we dive into the installation process, let's ensure that your system meets the necessary prerequisites:

  • Ubuntu 20.04 installed on your machine
  • Root access or a user account with sudo privileges
  • Stable internet connection

Step 1: Update System Packages

Before installing any new software, it is always recommended to update the system packages. Open a terminal and run the following commands:

sudo apt update sudo apt upgrade

Step 2: Install VNC Server

Now, let's proceed with the installation of VNC Server:

sudo apt install vncserver

Step 3: Configure VNC Server

After the installation, we need to configure VNC Server:

  1. Start the VNC Server setup by running the command:vncserver
  2. Set a password for VNC Server (minimum 6 characters) and verify it.
  3. Choose a view-only password (optional) if you wish to set one.
  4. Restart the VNC Server for the changes to take effect:sudo systemctl restart vncserver-x11-serviced.service

Step 4: Configure Firewall

In order to allow VNC traffic through the firewall, we need to open the necessary ports:

sudo ufw allow 5901 sudo ufw enable

Step 5: Connect to VNC Server

Now that we have installed and configured VNC Server, we can connect to it using a VNC viewer. Simply follow these steps:

  1. Launch your preferred VNC viewer application (RealVNC, TightVNC, etc.).
  2. Enter the IP address of your Ubuntu machine followed by the port number (e.g., 192.168.1.100:5901).
  3. Provide the password you set during the configuration process.
  4. Click "Connect" or a similar option to establish the connection.

Conclusion

Congratulations! You have successfully installed and configured VNC Server on your Ubuntu 20.04 machine. Now you can seamlessly access your Ubuntu desktop remotely using a VNC viewer. Enjoy the convenience of managing your server from anywhere in the world!

If you encounter any issues during the installation or have further questions, feel free to reach out to TecAdmin's support team for assistance.
