Why don't touchscreen calibration settings apply on lubuntu 17.10?

Question

linux

On the terminal (lubuntu 17.10 all packages are up to date) there is a touchpad "BeeTouch TouchSystems BeeTouch USB Touchscreen" (at least that's how the system defines it). It works, but all movements occur only in a small square in the upper left corner - a standard situation, not calibrated. I put xinput_calibrator and through it I start the calibration procedure, everything is ok. I get settings:

Section "InputClass"
  Identifier	"calibration"
  MatchProduct	"BeeTouch TouchSystems BeeTouch USB Touchscreen"
  Option	"MinX"	"-9"
  Option	"MaxX"	"2108"
  Option	"MinY"	"747"
  Option	"MaxY"	"2453"
  Option	"SwapXY"	"0" # unless it was already set to 1
  Option	"InvertX"	"0"  # unless it was already set
  Option	"InvertY"	"0"  # unless it was already set
EndSection

I save it to the /etc/X11/xorg.conf.d/99-calibration.conf folder and along the way to /usr/share/X11/xorg.conf.d/99-calibration.conf (perhaps the program itself created the files there, but the fact that the settings are prescribed).
Neither immediately after the calibration, nor after the reboot - nothing has changed, in the X11 logs it was written that no drivers were found for the device - I installed it from the office. site, the error has disappeared, but the settings are still not applied.

With a different touchpad on a different machine, everything worked right away.
