Linux 禁用笔记本触摸板

1. 查看有什么设备

xinput list

输出：

⎡ Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
⎜   ↳ PS/2 Logitech Wheel Mouse                   id=14    [slave  pointer  (2)]
⎜   ↳ USB OPTICAL MOUSE                           id=10    [slave  pointer  (2)]
⎣ Virtual core keyboard                       id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard                 id=5    [slave  keyboard (3)]
    ↳ Power Button                                id=6    [slave  keyboard (3)]
    ↳ Video Bus                                   id=7    [slave  keyboard (3)]
    ↳ Video Bus                                   id=8    [slave  keyboard (3)]
    ↳ Sleep Button                                id=9    [slave  keyboard (3)]
    ↳ USB2.0 HD UVC WebCam                        id=11    [slave  keyboard (3)]
    ↳ Asus WMI hotkeys                            id=12    [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard                id=13    [slave  keyboard (3)]

那么PS/2 Logitech Wheel Mouse就是我的触摸板了. 设备id=14.
