Ubuntu 20.04 VNC Server

The Ultimate Guide to Setting Up Your VNC Server

Greetings, fellow tech enthusiasts! Ubuntu 20.04 is a popular operating system used by many, and one of its most useful features is the VNC server. In this article, we’ll show you how to set up your very own VNC server, its advantages and disadvantages, and answer some frequently asked questions about it. So, let’s dive in!

Introduction

VNC, or Virtual Network Computing, allows you to remotely access and control a computer over a network connection. With the Ubuntu 20.04 VNC Server, you can securely connect to your computer from any device with VNC viewer software installed. This is especially useful for developers and system administrators who need to access their Ubuntu machines while away from the office.

The Ubuntu 20.04 VNC server is open-source software, which means it is free to use and can be modified to suit your needs. It uses the Remote Frame Buffer (RFB) protocol to provide a graphical interface to a remote user. This enables users to remotely connect to their Ubuntu machine, just as if they were sitting in front of it.

When you use the Ubuntu 20.04 VNC server, you can access your Ubuntu machine’s desktop environment, files, and applications, as well as run commands through the terminal. You can even transfer files between the local and remote computers.

Before we dive deeper into the Ubuntu 20.04 VNC server, let’s get started by setting it up!

Setting Up Your VNC Server

First, you need to install the VNC server package on your Ubuntu machine. To do this, open the terminal and type the following command:

$ sudo apt-get install tigervnc-standalone-server

Once the installation process is complete, you will need to configure your VNC server. In the terminal, type the following command:

$ vncserver

This will bring up a prompt asking you to set a password for your VNC server. This is an important step, as it will secure your connection and prevent unauthorized access. After setting the password, you will be asked to verify it.

Next, you will need to configure your VNC server to start automatically when your Ubuntu machine boots up. To do this, open the terminal and type:

$ sudo systemctl enable vncserver@:1.service

This will enable the VNC server to run at boot time. Finally, restart your VNC server for the changes to take effect. Type:

$ sudo systemctl restart vncserver@:1.service

Disadvantages

Bandwidth: Remote desktop sessions can consume a significant amount of bandwidth, which can be a problem if you have a slow or unreliable internet connection.

Latency: Due to network latency, remote sessions can be slower and less responsive than working directly on your Ubuntu machine. This can be especially frustrating when performing tasks that require a high degree of precision.
