Title:
change from xorg evdev driver to libinput driver breaks touchscreen
calibration configuration
Status in xserver-xorg-input-libinput package in Ubuntu:
Confirmed
Bug description:
when using xorg evdev driver with a touchscreen, it is possible to
configure the touchscreen calibration with InputClass options, e.g.:
Option "MinX" "4128"
Option "MaxX" "62751"
Option "MinY" "4075"
Option "MaxY" "63636"
however, the move to the libinput xorg driver does not use this so
upgrades result in touchscreens that no longer are calibrated.
Additionally, the normal touchscreen calibration program in Ubuntu,
xinput_calibrator, does not work with the libinput xorg driver. This
results in a mis/un-calibrated touchscreen, and no way to calibrate
it.
