- identify the input :
khadas@Khadas:~$ lsusb
…
Bus 001 Device 009: ID 222a:0001 ILI Technology Corp. Multi-Touch Screen
…
then create a udev.rules
khadas@Khadas:~$ sudo nano /etc/udev/rules.d/99-calibration.rules
ATTRS{idVendor}==“222a”, ATTRS{idProduct}==“0001”, ENV{LIBINPUT_CALIBRATION_MATRIX}=“0 -1 1 1 0 0 0 0 1”
reboot, and everything is fine
