Touch Screen Calibration

  1. If there's any deviations of the touch screen, you need to calibrate it. On the touch screen, use a mouse, to click Menu, -> Preference -> Calibrate Touchscreen. <img src="1.png" />
  2. Then the screen will show 4 points. You need to tap them one by one to calibrate. <img src="" />
  3. After calibration, you will get the following. Copy the contents in the red box. <img src="1.jpg" />
  4. In the terminal, type in

    <code>sudo nano /etc/X11/xorg.conf.d/99-calibration.conf
    </code>

    Paste what you have copied just now to the file

    Press Ctrl + X, select Y, and then press Enter to save the file

  5. In the terminal, type in

    <code>sudo reboot
    </code>

After rebooting, the calibration will be done. <img src="" />
