CALIBRATION
If the touch of RPi LCD is not calibrated, you can calibrate the touch screen.
1. Copy and install calibrator tool
cp LCD-show/xinput-calibrator_0.7.5-1_armhf.deb ~/
sudo dpkg -i -B xinput-calibrator_0.7.5-1_armhf.deb
2. Install X service
sudo apt-get install xserver-xorg-input-evdev
sudo cp -rf /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf
sudo reboot
3. Running calibrator and finish calibration
DISPLAY=:0.0 xinput_calibrator
4. Saving the calibration data to 99-clibration.conf file
sudo mkdir /etc/X11/xorg.conf.d
sudo nano /etc/X11/xorg.conf.d./99-calibration.conf
The calibration data looks like；
