In this article, we'll walk you through the process of configuring a VNC server on Ubuntu 20.04, which allows remote access to your graphical desktop from other computers.

The Problem with Auto Logins

Auto logins are a convenient feature that can be set up to automatically log in to your Ubuntu machine without requiring user input. However, if you're experiencing issues with the video card driver, this feature may not work as expected. In such cases, simply configuring auto login will not solve the problem.

How Does VNC Work?

VNC (Virtual Network Computing) is a remote desktop protocol that allows users to access and control another computer's graphical desktop over a network connection. The `vino-server` application is responsible for handling logins, but it only starts after a user has logged in.

Setting Up VNC on the Login Screen

To set up VNC on the login screen of your Ubuntu 20.04 machine, you'll need to follow these steps:

1. Install the required gnome packages by running the command `sudo apt-get install vnc4server`.

2. Start by installing the necessary gnome packages using the following command: `sudo apt-get install -no-install-recommends ubuntu-desktop`. This will help keep your GUI minimal and avoid installing unnecessary tools and apps.

Step 1: Install Required Gnome Packages

To set up VNC, you'll need to install the required gnome packages. For this, run the following commands:

* `sudo apt-get install vnc4server` (installing VNC server package)

* `sudo apt-get install gnome-panel gnome-settings-daemon metacity nautilus gnome-terminal` (installing gnome packages)

Step 2: Edit the VNC Server File

Next, you'll need to edit the `/usr/bin/vncserver` file. Open this file in a text editor using `sudo nano /usr/bin/vncserver`. Find the line `# exec /etc/X11/xinit/xinitrc.nn` (line no 57) and comment it out.

Step 3: Start VNC Server

Now, start the VNC server by running the command `vnc4server`.

That's it! With these steps, you should now have a functional VNC server set up on your Ubuntu 20.04 machine. You can access your remote desktop using any VNC client software.
