How to Install and Configure TigerVNC on Ubuntu 20.04

When you start or restart the TigerVNC server, a series of commands are automatically executed. To execute these commands, you need permissions for the `~/.vnc/xstartup` file. Create this file by running `nano ~/.vnc/xstartup`.

The next step is to set up TigerVNC to use Xfce. The password file is stored in the `~/.vnc` directory, which is generated if it doesn't already exist. You will be asked whether you want to enter a view-only password (y/n). If you opt for this, the user won't be able to interact with the VNC instance using their mouse or keyboard.

You'll need to run the `vncpasswd` command without sudo to change your user's password. This command is used to build the initial user configuration and configure the password after the VNC server has been installed.

To install TigerVNC on Ubuntu 20.04, use the following command: `sudo apt install tigervnc-standalone-server`. This is a high-performance VNC server that is actively maintained.

Each VNC server has its own strengths and weaknesses when it comes to speed and security. TightVNC, TigerVNC, and x11vnc are just a few of the VNC servers available in the Ubuntu repository.

As a user with sudo capabilities, run the following command: `sudo apt update`. This may take some time depending on your system. It's a good idea to install Xfce packages first, as this will help you get started with using your remote server quickly and efficiently.

Xfce is a lightweight, fast, and stable desktop environment that's ideal for use on a remote server. You could also choose to install Gnome, which is Ubuntu 20.04's default desktop environment. There are many other desktop environments available in the Ubuntu repository.

If you're using Ubuntu on your desktop, you may skip this step. However, if you're using it on a server, you'll need to handle it via the command line and won't have a graphical environment pre-installed.

In this tutorial, we will install and configure TigerVNC on Ubuntu 20.04. VNC is a free and open-source alternative to Microsoft's RDP protocol (RDP). It allows you to operate another computer remotely using your keyboard and mouse. Virtual Network Computing (VNC) is a graphical desktop sharing technology that makes it possible.

Before we begin discussing how to install and configure TigerVNC on Ubuntu 20.04, let's briefly understand what VNC is.
