Touchscreen calibration nonexistent? Ubuntu 18.04, toughbook cf-19 mk7

Asked by WarrenSensei on 2018-09-04

Moved my system's HD to a new body, a Toughbook CF-19 mk7, and most things are running beautifully after running updates.
One thing that is NOT running nicely is the touch screen.

My CF-19 came with the touch-only (no wacom) version, and it worked perfectly under the Windows 7 that the laptop shipped with.

What's wrong:
Touch works, but the calibration is off nadly enough to make it nearly useless. The touch area seems to think the screen is a good inch or so larger than it really is. I can do gross actions like scrolling, but poking buttons or other objects is literally hit or miss, increasingly useless as you go away from the center of the screen.

I have tried:
* Downloading, installing, and running "xinput_calibrator" (runs, produces output, does nothing)
* following instructions for xinput_calibrator to "make this permanant" by adding output to /usr/share/x11/xorg.conf.d/99-calibration.conf (no effect)
* following instructions for xinput_calibrator to "make this permanant" by adding output to /etc/x11/xorg.conf.d/99-calibration.conf (causes login loop in gnome, needed to log into Wayland session and delete)
* following instructions for xinput_calibrator to "make this permanant" by adding output to /usr/share/x11/xorg.conf.d/40-libinput.conf (no effect)

There are old instructions pertaining to libinput-calibration-matrix, but they don't seem to exist anymore?

Any help or suggestions or direction is appreciated!
