Guide to Disabling the Laptop Touchscreen on a Linux OS

Are you looking for a way to disable your laptop touchscreen on a Linux operating system? This guide will walk you through the process step-by-step. We'll explore different methods and configurations that can help you achieve this, ensuring your needs are met whether you're a casual user or a power user.

Why Disable Your Laptop Touchscreen?

There can be various reasons for wanting to disable your laptop touchscreen. Perhaps you have an accidental tap on the screen causing other applications to open or you might be dealing with a faulty touchscreen. Here are a few common scenarios why you might want to disable your laptop touchscreen:

Prevent accidental touches and taps that interfere with your work or daily usage.

Save battery life by reducing the power consumption of the touchscreen.

Install a new software or operating system that doesn't support your touchscreen properly.

Fixing a faulty touchscreen that is causing issues.

Preparation and Tools Needed

To disable your touchscreen, you need access to the command line interface in Linux. Most modern Linux distributions provide a terminal that you can open from the system menu or by pressing a combination of keys (such as Ctrl Alt T).

Method 1: Using xinput Command

The xinput command is a powerful tool for managing input devices in X Window System. Using the xinput command, you can inhibit your touchscreen to become non-responsive and effectively disable it.

Step 1: Identify Touchscreen Device

Open a terminal window and run the following command to list all input devices:

xinput list

The output will show you a list of all input devices, including your touchscreen. Note down the device ID number (e.g., ID12: ) of your touchscreen.

Step 2: Inhibit the Touchscreen

Once you have the ID, you can inhibit the touchscreen using the xinput command with the --enable and --disable options. Here's the command:

xinput --disable touchscreen_id

Replace touchscreen_id with the actual ID number of your touchscreen.

Note that this command only inhibits the touchscreen, and it will revert to its original state upon reboot or after you manually re-enable it. If you want to make it permanent, you need to add the command to a startup script or system configuration file.

Method 2: Modify Xorg Configuration

If you want a more permanent solution, you can modify the Xorg configuration to prevent the touchscreen from being activated. This method is more advanced and requires a deeper understanding of system configurations.

Step 1: Locate the File

Determine if your Linux distribution has an file. You can search for it in the following locations:

If you find an file, you can edit it. If you don't find it, you may need to create one.

Step 2: Edit the Xorg Configuration

If you are editing the main file, you can add a configuration section for your touchscreen. Here's an example of how to configure your touchscreen to be disabled:

Section "InputClass" Identifier Touchscreen Disable MatchIsTouchscreen on Option KeyboardLayout us Option SendCoreEvents off EndSection

If you are using a configuration file in the directory, the file could look something like this:

[Section "InputClass"] Identifier "Touchscreen Disable" MatchIsTouchscreen "on" Option "SendCoreEvents" "off"EndSection

Step 3: Restart X11

Once you have made the necessary modifications, restart your X11 server to apply the changes. If you are not using a graphical login, you can log out and log back in. If you are using a graphical login, you can usually restart X11 by pressing Ctrl Alt F1 to switch to a text login and then Ctrl Alt F7 to return to the graphical interface.

Conclusion

Disabling your laptop touchscreen in a Linux operating system can be done through various methods, and the best approach depends on your specific needs and level of technical expertise. Whether you opt for a temporary solution using the command line or a more permanent configuration in the Xorg settings, this guide should provide you with the knowledge to successfully disable your touchscreen on your Linux laptop.
