Disable notebook with keyboard under Ubuntu

Want to disable the laptop with the keyboard (Ubuntu) as long as 2 commands.

1. Open the terminal and enter:

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)]

Unplug the external keyboard and use the exclusion method to find the notebook with its own keyboard. My notebook keyboard is an at translated Set 2 keyboard with ID 15.

2. Enter:

xinput set-prop 15 "Device Enabled" 0

The 15 in the code refers to the ID of my notebook keyboard, and you replace it with the ID of the device you want to disable.
