[FIX] Ubuntu 20.04 LTS Keyboard and Mouse not Working

Ubuntu 20.04 LTS (Long Term Support) is the latest major release of the popular Linux-based operating system. With a focus on stability and security, this version promises to be a reliable choice for users looking to upgrade. However, like any software, it is not without its issues. One common problem reported by Ubuntu users is the keyboard and mouse not working. This can be frustrating and prevent you from using your computer properly. In this article, we will discuss some possible solutions to fix this problem.

1. Check the Connections

The first thing you should check is the physical connection of your keyboard and mouse. Make sure they are properly connected to your computer. If you are using a wireless keyboard or mouse, check the batteries and ensure they are not dead. If they are, replace them and see if it solves the issue.

2. Check if your Keyboard and Mouse are Detected

It is possible that your Ubuntu system is not detecting your keyboard and mouse. To check this, you can use a command in the terminal. Open the terminal by pressing Ctrl + Alt + T and type in the following command:

sudo dmesg | grep keyboard

If your keyboard is detected, it will display a line with “keyboard” in it. If your mouse is not working, type in the following command:

sudo dmesg | grep mouse

If your mouse is detected, it will display a line with “mouse” in it. If nothing is displayed, it means that your keyboard and mouse are not recognized by the system.

3. Try a Different Keyboard and Mouse

If your keyboard and mouse are not detected, try using a different set of keyboard and mouse. This will help you determine if the issue is with your devices or your system.

4. Check the USB Ports

If your keyboard and mouse are connected via USB, make sure the ports are functioning properly. You can try plugging them into different USB ports to see if it makes a difference. If your ports are not working, you may need to replace them.

5. Update your System

Make sure your Ubuntu system is up to date. Sometimes, outdated software can cause compatibility issues with hardware. To update your system, open the terminal and type in the following command:

sudo apt update && sudo apt upgrade

This will update all the packages on your system to the latest version.

6. Check the Mouse and Keyboard Settings

Sometimes, the issue can be with the settings on your computer. To check this, go to “Settings” and click on “Universal Access.” Make sure the options for “Mouse” and “Keyboard” are turned on. You can also adjust the speed and sensitivity of your mouse and keyboard from here.

7. Reinstall the Input Drivers

If your keyboard and mouse are still not working, you can try reinstalling the input drivers. To do this, open the terminal and type in the following command:

sudo apt-get install xserver-xorg-input-all

This will install all the input drivers on your system.

8. Try a Different Desktop Environment

If none of the above solutions work, the issue may be with your desktop environment. Ubuntu comes with a default desktop environment called GNOME. You can try switching to a different desktop environment such as KDE or Xfce to see if it solves the problem. To do this, log out of your current session, click on the gear icon next to the “Sign In” button, and select a different desktop environment.
