Configure VNC Server on Ubuntu 20.04

In this tutorial, we will guide you step-by-step through setting up the VNC server on Ubuntu 20.04. We will install a Linux desktop XFCE on the server, then install and configure the VNC server using TightVNC.

To begin, make sure your Ubuntu repository is updated, then upgrade your system using the following commands:

```

sudo apt update

sudo apt full-upgrade

```

Next, create a new user named 'edward' for VNC access. Add this user to the sudo group for root privileges access:

```

usermod -a -G sudo edward

```

Now, install XFCE desktop including all dependencies using the following command:

```

sudo apt install xfce4 tightvncserver

```

Once the installation is complete, initiate the VNC configuration for the 'edward' user with the following command:

```

vncserver -geometry 1024x768 -depth 16

```

You will be asked for the VNC server password - type your password.

To configure the VNC server for using the XFCE desktop, navigate to the `.vnc` directory and run the `ls -lah ~/.vnc/` command. You should see a new configuration directory created automatically by the `vncserver` command.

You can also check the VNC server status using the following command:

```

vncserver -list

```

By default, the user who logs in to the server using the 'view-only' password will not be able to control the mouse and keyboard. However, you can enable or disable this feature as needed.

To connect to the VNC server through SSH tunneling, follow these steps:

* Install OpenSSH on your local machine if it's not already installed.

* Create an SSH tunnel using the following command: `ssh -L 5900:localhost:5900 edward@your-ubuntu-server-ip`

* Connect to the VNC server using the following command: `vncviewer localhost:5900`

For this tutorial, we will be using the XFCE desktop as our VNC desktop environment. Linux has several desktop environments such as Gnome, Unity, KDE, LXDE, and XFCE, among others.

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