then, use xinput –list to display the pointers list and find your touch device (retrieve the name and the ID)

use xinput list-props [YOUR DEVICE ID] to display the current parameters

In case you need to calibrate the new matrix, use xinput set-prop '[NAME OF YOUR TOUCH DEVICE]' 'coordinate transformation matrix' [YOUR MATRIX COORDONATE]
