I've upgraded from Debian 8 to Debian 9, and they've gotten rid of evdev. I had been using evdev to calibrate the resistive touch screen on one of my weirder computers (actually a Fujitsu ScanSnap N1800 kiosk scanner).
Here's what I used to use to calibrate it:
Code:
xinput set-prop "Fujitsu Takamisawa USB Touch Panel" "Evdev Axis Calibration" 850 16083 1000 15853
But if I list the available properties now, obviously evdev properties no longer show up:
Code:
xinput list-props "Fujitsu Takamisawa USB Touch Panel"
Device 'Fujitsu Takamisawa USB Touch Panel':

I don't see any property which looks similar to the one I originally used, but I do see "libinput Calibration Matrix (518)".
Am I right in thinking I'm going to have to somehow translate my evdev corner calibration coordinates into a transformation matrix? Any idea how to do this other than trial and error? Thanks!
