通过xinput先查看一些都有哪些设备

$xinput     #或者 xinput list

显示结果如下:

查看设备属性,10为我的设备ID，也可直接使用设备名：

$xinput list-props 10

输出如下：

用过set-porp来设置设备的属性。

禁用触摸板

xinput set-prop 14 'Device Enabled' 0  #通过设备编号+属性名禁用触摸板

xinput set-prop 'Beijing Qltouch Tech Co.,LtD   USB TouchScreen' 'Device Enabled' 0 #通过设备名+属性名禁用触摸板

启用触摸板

xinput set-prop 14 132 1 #通过设备编号+属性编号来设置

xinput set-prop 'Beijing Qltouch Tech Co.,LtD   USB TouchScreen' 132 1 #通过设备名+属性编号启用

刚才说了在我的电脑设备“Beijing Qltouch Tech Co.,LtD USB TouchScreen”和14是等价的，Device Enabled和132是等价的，所以两者可以替代，于是敲命令的时候可以偷懒下。不过像这样看着比较直观这个命令到底是干什么。

xinput set-prop 'Beijing Qltouch Tech Co.,LtD   USB TouchScreen' 'Device Enabled' 0

通过脚本快速启用和禁用触摸板

每次如果都敲命令也是比较麻烦的，通过脚本就很快的切换了。

#!/bin/bash
if [ $1 == 'on' ]
then
    set-prop ' Beijing Qltouch Tech Co.,LtD   USB TouchScreen ' 1
    echo "触摸板开启成功！"
elif [ $1 == 'off' ]
then
    set-prop ' Beijing Qltouch Tech Co.,LtD   USB TouchScreen ' 0
    echo "触摸板关闭成功！"
else
    echo "请输入参数：on/off"
    echo "开启触摸板：touchpadEnable on"
    echo "禁用触摸板：touchpadEnable off"
fi

通过禁用触摸板，确实给我解决了不少的麻烦。
开机自动禁用触摸板

但是这样在开机重启后又恢复了，对有些同学喜欢关机而不是休眠的同学确实还要改进，就是让开机的时候自动运行禁用触摸板的命令。
在~/.config/autostart/下创建一个启动器xinput.desktop文件，内容如下

[Desktop Entry]
Type=Application
Exec=xinput set-prop ' Beijing Qltouch Tech Co.,LtD   USB TouchScreen ' 'Device Enabled' 0
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
Name[zh_CN]=touchpad enable
Name=touchpad enable
Comment[zh_CN]=禁用触摸板
Comment=禁用触摸板

这样在开机的时候就能自动禁用触摸板了。

触摸屏横屏变竖屏解决

• 交换x、y轴

  xinput --set-prop '7' 'Evdev Axes Swap' 1           // 7为我当时的端口id，会变化。  用名字代替也可以。

• 反转y轴

  xinput --set-prop '7' 'Evdev Axis Inversion' 0 1

目录: /usr/share/X11/xorg.conf.d/ 10-evdev.conf 界面显示的配置文件，可以通过这个文件调整触摸点。看清楚再改有风险。

校准命令 ： xinput_calibrator 然后开始点击确定触摸屏，完成后输出如下：

Setting calibration data: 0, 32767, 0, 32767
Calibrating EVDEV driver for "Touch Touch Device F47WH00U-CT-A1-2P" id=10
current calibration values (from XInput): min_x=0, max_x=32767 and min_y=0, max_y=32767


Doing dynamic recalibration:

如需更改在 Driver "evdev" 下面添加 矫正输出 Option "Calibration" "-23 32805 32710 -11" 。
