You are reading a sample chapter from Ubuntu 20.04 Essentials. This allows you to launch multiple desktop sessions in the background on the remote system and view and control those desktops over a network or internet connection.

The second option, covered in the next chapter entitled “Ubuntu Remote Desktop Access with VNC”, is intended for situations where you need to start and access one or more remote desktop sessions on a remote server-based system, regardless of whether the remote system has a graphical console attached. When configured, you will take over your desktop session and view and control it remotely. The approach covered in this chapter is useful if you primarily use Ubuntu as a desktop operating system and require remote access to your usual desktop session. 1.1 Remote Desktop Access Typesīefore starting it is important to understand that there are essentially two types of remote desktop access. The Ubuntu remote desktop functionality is based on technology known as Virtual Network Computing (VNC) and in this and the next chapter we will cover the key aspects of configuring and using remote desktops within Ubuntu. It is also useful in situations where a co-worker or IT support technician needs access to your desktop to resolve a problem. This is useful if you need to work on your computer when you are away from your desk such as while traveling. It enables you or another person, for example, to view and interact with your Ubuntu desktop environment from another computer system either on the same network or over the internet. Remote desktop access can be useful in a number of scenarios. In fact, there are even apps available for Android and iOS that will allow you to access your Ubuntu desktop from just about anywhere that a data signal is available. This can be achieved regardless of whether that system is running Linux, Windows or macOS. Although not enabled by default, it is relatively straightforward to display and access an Ubuntu desktop from a system anywhere else on a network or the internet. Ubuntu can be configured to provide remote access to the graphical desktop environment over a network or internet connection.
