校准触摸屏

我在校准自助服务终端系统的触摸屏时遇到问题。我已经安装xinput_calibrator并执行：

$ xinput_calibrator -v
DEBUG: XInputExtension version is 2.3
DEBUG: Skipping virtual master devices and devices without axis valuators.
DEBUG: Skipping device 'Virtual core XTEST pointer' id=4, does not report Absolute events.
DEBUG: Skipping device 'PS/2 Generic Mouse' id=12, does not report Absolute events.

current calibration values: min_x=0, max_x=65535 and min_y=0, max_y=65535
If these values are estimated wrong, either supply it manually with the --precalib option, or run the 'get_precalib.sh' script to automatically get it (through HAL).

copy the snippet below into '/etc/X11/xorg.conf.d/99-calibration.conf' (/usr/share/X11/xorg.conf.d/ in some distro's)
Section "InputClass"
  Identifier    "calibration"
  MatchProduct  "MicroTouch Systems, Inc. MicroTouch USB Touchscreen - EX II"
  Option    "MinX"  "10961"
  Option    "MaxX"  "55163"
  Option    "MinY"  "54602"
  Option    "MaxY"  "10485"
  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

但这并不能改变屏幕的校准错误，我想我需要使用该xinput_calibrator --precalib选项，因为生成的值是错误的。

我怎样才能获得这些值并放入该命令中？

更新

根据评论，这里有更多详细信息：

  1. 上面的输出保存在/etc/X11/xorg.conf.d/99-calibration.conf
  2. .local/share/xorg/Xorg.0.log请查找应用上述配置前后文件内容的相关部分->这里<-

xinput_calibrator 用于使用 evdev 校准触摸屏。用于触摸屏的驱动程序是 libinput。所以你需要使用选项CalibrationMatrix或TransformationMatrix。
