How to Install VNC Viewer on Ubuntu 20.04

VNC (Virtual Network Computing) is a remote desktop protocol that allows you to access and control another computer's desktop over a network. In this tutorial, we will show you how to install VNC viewer on Ubuntu 20.04.

To set up VNC, you need to create a password for your account. To do this, open the KDE System Settings and go to Sharing > Desktop Sharing > Configure. Here, you can set a hard-to-guess password for your account.

Another option is to use Krfb, which is the default VNC server in Kubuntu. You can configure Krfb by going to System Settings > Sharing > Desktop Sharing > Configure. To run Krfb automatically on startup, you need to add it to your upstart configuration file.

Alternatively, you can use x11vnc, a VNC server that is not dependent on any one particular graphical environment. You can start x11vnc while your computer is still showing a login screen, making it easy to test your connectivity.

To configure x11vnc, you need to specify the options you want to use. For example, you can set x11vnc to only allow local connections by including the -localhost option. You can also set it to continually listen for connections by including the -forever option.

Here are a few common settings that you may want to adjust depending on your environment:

* To set x11vnc to start automatically, add the following command to your upstart configuration file: `x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /home/USERNAME/.vnc/passwd -rfbport 5900 -shared`

* To create a password file, use the following command: `x11vnc -storepasswd`

It's also important to ensure that you have uninstalled any other VNC programs first so that they don't interfere with x11vnc.

To allow connections from anywhere, open a terminal and run the command: `gsettings reset network-interface`. To only allow local connections, run the command: `gsettings set network-interface lo`.

In conclusion, installing VNC viewer on Ubuntu 20.04 is a straightforward process that requires some basic configuration. By following these steps, you can easily access and control another computer's desktop over a network.
