How to disable and enable laptop keyboard. You can use xinput to float the input device under X.

1. Execute the command xinput list to list your input devices.
2. Locate AT Translated Set 2 keyboard and take note of its id number; this will be used to disable the keyboard. Also, take note of the number at the end, [slave keyboard (#)]; this is the id number of the master, which will be used to re-enable your keyboard.
3. To disable the keyboard, execute the command xinput float <id#>, where <id#> is your keyboard’s id number. For example, if the id was 10, then the command would be xinput float 10.
