Introduction to Touch Screen on Linux

Touch screen technology is being increasingly adopted in various devices for its ease of use and intuitive interface. While Linux systems support touch screens, enabling and configuring these devices may require specific steps, varying according to hardware and software specifications.

Enabling Touch Screen on Linux

To use touch screen functionality on Linux, it is generally necessary to enable the device through the operating system's settings. The process involves identifying the device and configuring it using built-in tools and drivers specific to the Linux distribution.

Using the xinput Command

The xinput command is a straightforward method for enabling and managing touch screen devices on Linux systems. It provides comprehensive control over input devices, allowing users to list, enable, or disable them.

1. Open a terminal window.
2. Type xinput list to display a list of connected input devices.
3. Locate your touch screen device in the list. Note its ID number.
4. Enable the device using the command xinput enable [device ID].

Configuring Touchscreen Settings in xorg.conf

The xorg.conf file allows for advanced configuration of input devices, including touch screens. Users can manually edit this file to adjust settings for touch screen accuracy and responsiveness.

1. Navigate to /etc/X11/xorg.conf.d/.
2. Create or edit a file with a name like 99-touchscreen.conf.
3. Add the following configuration:

   Section InputClass
     Identifier touchscreen
     MatchProduct Your Touchscreen Device Name
     Driver evdev
     Option Calibration minx miny maxx maxy
     Option InvertX false
     Option InvertY false
     Option SwapAxes false
   EndSection
         

Applying Calibration Using xinput_calibrator

For precise touch input, calibrating your touch screen using xinput_calibrator is recommended. This tool provides an interactive method to determine the optimal calibration settings.

1. Install xinput_calibrator via the command sudo apt-get install xinput-calibrator.
2. Run the calibrator using xinput_calibrator command.
3. Follow on-screen instructions to complete calibration.
4. Save the output for permanent application on your system.
