Installing VNC Server on Ubuntu: A Step-by-Step Guide

Introduction

VNC (Virtual Network Computing) is a remote desktop protocol that allows users to access and control a remote computer over the internet. It is widely used in various industries, including education, research, and business. Ubuntu is a popular Linux distribution that offers a range of tools and software for managing and configuring remote desktop connections. In this article, we will guide you through the process of installing VNC Server on Ubuntu.

Prerequisites

Before installing VNC Server, ensure that your Ubuntu system meets the following requirements:

• Ubuntu version: 18.04 or later
• CPU: 64-bit processor
• Memory: 4 GB or more
• Storage: At least 10 GB of free disk space
• Internet connection: A stable internet connection is required for VNC Server to function

Step 1: Update and Upgrade Ubuntu

To ensure that your Ubuntu system is up-to-date, run the following command:

sudo apt update

sudo apt upgrade -y

Step 2: Install VNC Server

VNC Server is included in the Ubuntu package manager, so you don’t need to install it separately. However, if you want to install it from source, you can do so using the following command:

sudo apt install vnc-server

Step 3: Configure VNC Server

By default, VNC Server uses the vnc-server service, which is started automatically when you boot your system. However, you can configure VNC Server to start on boot by adding the following line to your /etc/default/vnc-server file:

start on boot

Then, restart your system to apply the changes:

sudo systemctl enable vnc-server

sudo systemctl start vnc-server

Step 4: Configure VNC Server Settings

To configure VNC Server settings, you can use the following command:

sudo vncconfig

This will open the VNC Server configuration file in your default text editor. You can edit the settings to suit your needs, such as changing the port number, username, and password.

Step 5: Start VNC Server

To start VNC Server, run the following command:

sudo service vnc-server start

Step 6: Configure VNC Client

To connect to VNC Server, you need to install a VNC client. Some popular VNC clients include:

• VNC Viewer: A free and open-source VNC client for Windows, macOS, and Linux.
• VNC4: A free and open-source VNC client for Windows, macOS, and Linux.
• Xvnc: A free and open-source VNC client for Windows, macOS, and Linux.

You can download and install the VNC client of your choice.
