7. Touch反转设置
7.1. xinput list
//情况如下，驱动为ILITEK Multi-Touch-V3000
? Virtual core pointer                       id=2   [master pointer (3)]
?   ? Virtual core XTEST pointer                 id=4   [slave pointer (2)]
?   ? ILITEK Multi-Touch-V3000                   id=9   [slave pointer (2)]
?   ? ILITEK Multi-Touch-V3000                   id=10   [slave pointer (2)]
?   ? A4Tech USB Mouse                           id=8   [slave pointer (2)]
? Virtual core keyboard                      id=3   [master keyboard (2)]
    ? Virtual core XTEST keyboard                id=5   [slave keyboard (3)]
    ? gpio-keys                                  id=11   [slave keyboard (3)]
    ? Logitech USB Keyboard                      id=6   [slave keyboard (3)]
    ? Logitech USB Keyboard                      id=7   [slave keyboard (3)]
7.2.配置文件
7.2.1.查看/usr/share/X11/xorg.conf.d/目录下是否有40-libinput.conf这个文件。
opt:           没有这个文件，则需要安装
sudo apt-get install xserver-xorg-input-libinput
安装完成后ls一下，就可以看到在/usr/share/X11/xorg.conf.d/目录下存在该文件

7.2.2.复制该文件到/etc/X11/xorg.conf.d/目录下。

    opt:           一开始xorg.conf.d这个目录在/etc/X11可能没有，需要自己创建。

    cd /etc/X11
    sudo mkdir xorg.conf.d

    sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/
    sudo gedit /etc/X11/xorg.conf.d/40-libinput.conf

7.2.3.进入/etc/X11/xorg.conf.d/目录下修改40-libinput.conf 文件

找到touchscreen section

在Identifier下添加一行 Option “CalibrationMatrix” “你的校准矩阵”

我这里板子上需要旋转270度，所以写 Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"

90度       "0 -1 1 1 0 0 0 0 1"

180度      "-1 0 1 0 -1 1 0 0 1"

x ,y对调 "-1 0 1 1 0 0 0 0 1"

添加完成后

# Match on all types of devices but joysticks
Section "InputClass"
        Identifier "libinput pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection

Section "InputClass"
        Identifier "libinput keyboard catchall"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection

Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection

Section "InputClass"
        Identifier "libinput touchscreen catchall"
      Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection

Section "InputClass"
        Identifier "libinput tablet catchall"
        MatchIsTablet "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection
