How To Fix Touchpad Not Working on Ubuntu 20.04

Ubuntu 1

If you’re running Ubuntu 20.04 and your touchpad suddenly stops working, it can be a frustrating experience. However, there are several possible solutions to this issue. In this article, we will walk you through these solutions step by step.

Solution 1: Reinstall the Touchpad Driver

The first solution you can try is to reinstall the touchpad driver. This can be done using the terminal, which can be accessed by pressing Ctrl + Alt + T. Once the terminal is open, run the following commands:

sudo apt purge xserver-xorg-input-synaptics
sudo apt autoremove
sudo apt update
sudo apt install xserver-xorg-input-synaptics

These commands will uninstall the xserver-xorg-input-synaptics package, remove any unused packages, update the package list, and then reinstall the xserver-xorg-input-synaptics package.

Once you have run these commands, restart your system and check if the touchpad is working.

Solution 2: Edit the Touchpad Configuration File

Another solution is to edit the touchpad configuration file. This can also be done from the terminal. Open the terminal and run the following command:

sudo gedit /etc/modprobe.d/psmouse.conf

This command opens the psmouse.conf file in the text editor. Add the following line to the file:

options psmouse synaptics_intertouch=1

This line tells the system to use the synaptics_intertouch driver for the touchpad.

After adding this line, save and close the file. Then, run the following command in the terminal:

sudo modprobe -r psmouse && sudo modprobe psmouse

This command unloads and then reloads the psmouse module, which should now use the new driver.

Solution 3: Disable and Enable the Touchpad in Settings

If the above solutions do not work, you can try disabling and then enabling the touchpad in the Settings. To do this, go to “Settings” and navigate to “Mouse & Touchpad”. Here, you will see an option for “Touchpad”. Toggle this option off and then on again.

Solution 4: Restart the System

If all else fails, you can try restarting the system. This can be done from the terminal using the following command:

shutdown -r now

This command immediately restarts the system. After the restart, check if the touchpad is working.

Conclusion

If none of these solutions work, it may be helpful to check for any error messages related to the touchpad driver by running dmesg | grep psmouse in the terminal. Additionally, trying different kernel versions or reporting the issue as a bug to Ubuntu may also help resolve the problem.

Remember, troubleshooting is a process of elimination. It might take a few tries to find the solution that works for you. We hope this guide has been helpful in resolving your touchpad issues on Ubuntu 20.04.
