How to Install Tigervnc on Ubuntu 20.04

Tigervnc is a popular and widely-used Virtual Network Computing (VNC) software that allows users to remotely access graphical desktop environments on a remote server. In this article, we will guide you through the process of installing Tigervnc on Ubuntu 20.04.

Before starting, make sure you have a VNC viewer installed on your system. You can create an SSH connection on your local computer that securely forwards to the localhost connection for VNC by running the following command:

`ssh -L 59000:localhost:5901 -C -N -l server_username server_ip_address`

This will allow you to access the remote desktop on the VNC server from your Windows system.

Once connected, restart the VNC server by running the following command:

`vncserver -localhost no :1`

Next, save and close the file, then make it executable by running the following command:

`chmod +x ~/.vnc/xstartup`

After that, edit the xstartup file by moving it to a backup location with the following command:

`mv ~/.vnc/xstartup ~/.vnc/xstartup.bak`

If you ever want to change your password or add a view-only password, you can do so with the vncpasswd command.

To stop the VNC server instance that is running on port 5901, run the following command:

`vncserver -kill :1`

Once stopped, use the following command to connect to the VNC server:

`tigervncviewer -SecurityTypes VncAuth -passwd /home/username/.vnc/passwd :1`

You can also view the log file by navigating to `/home/username/.vnc/username:1.log`.

Starting applications specified in `/etc/X11/Xvnc-session` will ensure that all necessary settings are loaded. You can also specify custom settings by editing the xstartup file.

Finally, make sure that anybody who accesses the VNC server with a view-only password cannot VNC desktop with either Mouse or Keyboard by answering 'N' to the prompt. Once set up, you will get a prompt to set a View-Only password.

This article assumes basic knowledge of Linux and shell usage. Additionally, it is recommended to run Tigervnc on your own Virtual Private Server (VPS).

Tigervnc uses the Remote Frame Buffer (RFB) protocol to transmit mouse movements and keyboard input over the network, making it a reliable and secure solution for remote desktop access.

For those who are new to VNC, it's worth noting that Virtual Network Computing is a connection system that allows users to use their keyboard and mouse to interact with a graphical desktop environment on a remote server. In this tutorial, we will show you how to install Tigervnc on Ubuntu 22.04 LTS, which can be applied to other Debian-based distributions like Linux Mint, Elementary OS, Pop!_OS, and more.

By following these steps, you should now have a fully functional VNC server up and running on your Ubuntu 20.04 system.
