1.查看触摸屏驱动

bash 复制代码

root@xyy:~# xinput list
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Windows pointer                           id=6    [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Windows keyboard                          id=7    [slave  keyboard (3)]

2.修改/etc/X11/xorg.conf.d/40-libinput.conf配置文件：

旋转270° （右转）添加

bash 复制代码

 Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"

旋转90° （左转）添加

bash 复制代码

 Option "CalibrationMatrix" "0 -1 1 1 0 0 0 0 1"

旋转180° （颠倒）添加

bash 复制代码

 Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"

y轴旋转添加

bash 复制代码

 Option "CalibrationMatrix" "-1 0 1 1 0 0 0 0 1"

修改后的配置如下：

bash 复制代码

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" "0 1 0 -1 0 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
