想要禁用笔记本自带键盘(Ubuntu)只要2条命令。

1. 打开终端，输入：

xinput list

? Virtual core pointer                      id=2    [master pointer  (3)]
?   ? Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
?   ? HID Keyboard Device                       id=12   [slave  pointer  (2)]
?   ? G-Tech Wireless Dongle                    id=14   [slave  pointer  (2)]
?   ? ETPS/2 Elantech Touchpad                  id=16   [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)]
    ? Power Button                              id=9    [slave  keyboard (3)]
    ? Sleep Button                              id=10   [slave  keyboard (3)]
    ? HID Keyboard Device                       id=11   [slave  keyboard (3)]
    ? G-Tech Wireless Dongle                    id=13   [slave  keyboard (3)]
    ? AT Translated Set 2 keyboard              id=15   [slave  keyboard (3)]
    ? MSI WMI hotkeys                           id=17   [slave  keyboard (3)]

拔掉外接键盘，用排除法找到笔记本自带键盘。我的笔记本键盘是id为15的AT Translated Set 2 keyboard。

2. 输入：

xinput set-prop 15 "Device Enabled" 0

代码中的15指的是我的笔记本键盘的id，请自行根据自己想要禁用的装置的id替换。
