- Install it with the commands:
cd Elecrow-LCD4
sudo dpkg -i -B xinput-calibrator_0.7.5-1_armhf.deb
- Click the Men button on the task bar, choose Preference -> Calibrate Touchscreen.
- Finish the touch calibration following the prompts. Maybe rebooting is required to make calibration active.
- You can create a 99-calibration.conf file to save the touch parameters (not necessary if file exists).
