Ubuntu is a popular operating system that offers a user-friendly interface and a wide range of features. If you are using a touchscreen device with Ubuntu, you might want to customize its behavior to suit your needs. In this article, we will guide you through the process of changing the behavior of the touchscreen in Ubuntu.
Step 1: Open the Terminal
The first step is to open the Terminal, which is a command-line interface in Ubuntu. You can do this by pressing Ctrl+Alt+T on your keyboard or by searching for "Terminal" in the Ubuntu Dash.
Step 2: Install the Required Packages
Once the Terminal is open, you need to install the necessary packages to modify the touchscreen behavior. Type the following command and press Enter:
sudo apt-get install xinput-calibrator
This command will install the xinput-calibrator package, which is a tool used to calibrate touchscreens in Ubuntu.
Step 3: Calibrate the Touchscreen
After the installation is complete, you can calibrate your touchscreen. Type the following command and press Enter:
xinput_calibrator
This will launch the touchscreen calibration tool. Follow the on-screen instructions to calibrate your touchscreen. The calibration process involves touching certain points on the screen to align them accurately.
Step 4: Create a Startup Script
To make the changes permanent, you need to create a startup script that will apply the touchscreen behavior settings every time you boot into Ubuntu. Type the following command and press Enter:
sudo nano /etc/X11/Xsession.d/99-touchscreen-settings
This command will open a text editor called Nano and create a new file named 99-touchscreen-settings in the specified directory.
Inside the Nano text editor, paste the following lines:
#!/bin/bash
xinput set-prop "Your Touchscreen Name" "Coordinate Transformation Matrix" 0.5 0 0 0 0.5 0 0 0 1
Replace "Your Touchscreen Name" with the actual name of your touchscreen device. You can find the device name by running the command xinput in the Terminal and looking for the touchscreen entry.
Once you have pasted the lines and replaced the device name, press Ctrl+O to save the file and Ctrl+X to exit Nano.
Step 5: Restart Ubuntu
Now that you have created the startup script, you need to restart Ubuntu for the changes to take effect. You can do this by clicking on the power icon in the top-right corner of the screen and selecting "Restart".
Once Ubuntu restarts, your touchscreen should now behave according to the settings you specified in the startup script.
Congratulations! You have successfully changed the behavior of the touchscreen in Ubuntu. If you want to make further adjustments, you can edit the startup script by repeating Step 4.
Conclusion
Customizing the behavior of the touchscreen in Ubuntu can greatly enhance your user experience. By following the steps outlined in this article, you can easily calibrate your touchscreen and create a startup script to apply the desired settings. Enjoy your personalized touchscreen experience in Ubuntu!
