Package: xinput-calibrator
Version: 0.7.5+git20140201-1+b2
Debian 11, Kernel 5.10.105
The output is broken in terms that the resulting file is not compatible anymore
with current libinput.
The effect is that the Touch sensor calibration is not applied.
Output of actual xinput_calibrator (broken):
Section "InputClass"
Identifier "calibration"
MatchProduct "1c25000.rtp"
Option "MinX" "117"
Option "MaxX" "65738"
Option "MinY" "1256"
Option "MaxY" "65043"
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
Output corrected (works):
Section "InputClass"
Identifier "calibration"
MatchProduct "1c25000.rtp"
Option "TransformationMatrix" "1.03995747179332561054 0
-.02581842994747449101 0 1.07016884940723080440 -.03731343283582089552 0 0 1"
EndSection
Unfortunately the package is very old and not maintained (last commit 9 yo).
This leaves Debian without a proper way to calibrate touch screens (checking on
sid the package is the same, so still broken).
There's a fork/derived project with added features:
https://github.com/kreijack/xlibinput_calibrator
There are a few other solutions:
- Use a wrapper script, which use Debian provided old xinput_calibrator but with the
newer "TransformationMatrix", available here:
https://wiki.archlinux.org/title/Talk:Calibrating_Touchscreen#Wrapper_around_xinput_calibrator
(tested, working, modified to write directly to conf file)
- use an alternative calibration program, which can deal with the newer
libinput, for example the fowllowing in python/tk:
https://github.com/reinderien/xcalibrate
(tested, working, modified to write directly to conf file)
I could help the maintainer in the process of having a calibration tool up and
running.
