Linux 禁用笔记本自带键盘

# disable
xinput list | grep AT | egrep -o "id=[0-9]*" | egrep -o "[0-9]*" | xargs xinput disable

# enable
xinput list | grep AT | egrep -o "id=[0-9]*" | egrep -o "[0-9]*" | xargs xinput enable

• 原理：
  使用 xinput list 获取本机自带键盘的 id:

  xinput
  ⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
  ⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
  ⎜   ↳ 2.4G Mouse                              	id=8	[slave  pointer  (2)]
  ⎜   ↳ DELL09EC:00 27C6:01E0 Mouse             	id=10	[slave  pointer  (2)]
  ⎜   ↳ DELL09EC:00 27C6:01E0 Touchpad          	id=11	[slave  pointer  (2)]
  ⎜   ↳ PS/2 Generic Mouse                      	id=16	[slave  pointer  (2)]
  ⎜   ↳ HID 026d:0002 Consumer Control          	id=18	[slave  pointer  (2)]
  ⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
      ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
      ↳ Video Bus                               	id=6	[slave  keyboard (3)]
      ↳ Power Button                            	id=7	[slave  keyboard (3)]
      ↳ Integrated_Webcam_HD: Integrate         	id=9	[slave  keyboard (3)]
      ↳ Intel HID events                        	id=12	[slave  keyboard (3)]
      ↳ Intel HID 5 button array                	id=13	[slave  keyboard (3)]
      ↳ Dell WMI hotkeys                        	id=14	[slave  keyboard (3)]
      ↳ HID 026d:0002 Keyboard                  	id=17	[slave  keyboard (3)]
      ↳ HID 026d:0002 Consumer Control          	id=19	[slave  keyboard (3)]
      ↳ HID 026d:0002                           	id=20	[slave  keyboard (3)]
      ↳ AT Translated Set 2 keyboard            	id=15	[slave  keyboard (3)]
  

  使用 grep、egrep 获取对应的 ID，然后禁用
