How to calibrate touchscreen kiosk mode

Hi all!

I have a screen with a USB capacitive touch panel which is all working fine, except the locations are just a little out.

I wanted to calibrate it but I can figure out how. I searched and somewhere is said about xinput_calibrator but I couldn’t install that (maybe part of another package?)

Not sure if it is important but I am running the unit in kiosk mode with chromium loading my CCTV system.

The machine is a small X86 unit (I think an Intel N100)

The package name is xinput-calibrator:

apt-cache search xinput-calibrator
xinput-calibrator - Generic touchscreen calibration program for X.Org
