Linux xinput touchscreen - Shell-Bash

Introduction

The xinput command is a powerful tool for configuring and debugging input devices in Linux systems. In this article, we will focus on using xinput to configure a touchscreen device.

Prerequisites

Before we dive into configuring the touchscreen, make sure that your system has xinput installed. You can check this by running the following command in your terminal:

xinput --version

If you don't have xinput installed, you can install it by running the following command:

sudo apt-get install xinput

Finding the Touchscreen Device

To configure the touchscreen, we first need to find the device ID of the touchscreen. You can do this by running the following command:

xinput list

This will list all the input devices connected to your system. Look for a device labeled as a touchscreen or something similar. Take note of the device ID, which is a number within parentheses next to the device name.

Enabling and Disabling the Touchscreen

If you want to disable the touchscreen temporarily, you can run the following command:

xinput disable <device_id>

To enable the touchscreen, use the following command:

xinput enable <device_id>

Replace <device_id> with the actual ID of the touchscreen device.

Configuring Touchscreen Properties

You can use xinput to change various properties of the touchscreen, such as sensitivity, acceleration, and calibration. To see a list of properties that can be configured for a device, run the following command:

xinput list-props <device_id>

This will list all the configurable properties of the device, along with their current values. To change a property, use the following command:

xinput set-prop <device_id> <prop_id> <value>

Replace <prop_id> with the ID of the property you want to change, and <value> with the new value you want to set. Note that some properties may require specific values or ranges of values.

Conclusion

The xinput command is a powerful tool for configuring input devices in Linux systems. With this tool, you can easily enable or disable the touchscreen, and change various properties to suit your needs.
