As it turns out, the keyboard works perfectly fine everywhere else except on the Desktop. While some users are stuck with the keyboard not working on the login screen, there are also victims that aren’t able to use their mouse along with the keyboard. We’ve investigated the matter and have found the potential causes of the issue along with the workarounds that will get you back on the road. So, without further ado, let us get started with the possible causes of the problem. With all of that out of the way, we can now focus on the different workarounds that you can apply to get rid of the problem. Please follow through.

Method 1: Check Keyboard Layout

This is the most obvious thing that you should do whenever you face any issue regarding your keyboard. As it turns out, if you are not able to use your keyboard, it could be due to the keyboard layout being of a different language. If this case is applicable to you, the resolution is pretty simple. What you have to do is change the keyboard layout from the settings and you should be good to go. Follow the instructions below to change the keyboard layout:

Method 2: Turn off Slow Keys or Bounce Keys

Slow keys and bounce keys are features of the GNOME desktop environment. Slow keys is basically a feature that puts a delay between when the letter key is pressed on the keyboard and when that letter is displayed on the screen. If the slow keys feature is enabled, you will have to hold each key that you wish to press before it is registered. Bounce keys is almost a similar feature. Intended for users with physical disabilities, bounce keys is a feature that tells the system to ignore repeated and rapid presses of the same key based on its configuration. You need to turn these features off to restore the input to the default state. Here’s how to do it:

Method 3: Update your System

If you are not able to use the keyboard only on the desktop screen and it works perfectly fine everywhere else, then it is probably because of the bug with the gnome desktop icons. If this case is applicable to you, it is evident that your system is not up-to-date and needs to be updated as this bug has been fixed. To update your system, do the following: In case the issue is still not fixed, what you can do is install different desktop icons and uninstall the gnome-desktop-icons for the time being. To remove the gnome desktop icons package, use the sudo apt purge gnome-desktop-icons command. Once removed, you can install another file manager and you’ll be good to go.

Method 4: Reinstall Ubuntu

As it turns out, if you installed a fresh copy of the Ubuntu 20.04 version, and you have other external media connected to the system, the problem of keyboard and mouse not working could be because of that. If this case is applicable to you, what you have to do is reinstall Ubuntu while making sure that no other external USB devices or other media are connected to the system except the USB drive that has the installation media. If you have some important information, you can either back it up or don’t partition the home directory during the installation.
