Eu tenho um laptop Samsung np870z5e com o Numpad integrado com o Ubuntu 16.04 e o udev 229.
Eu tenho um botão 'Fn-lock', se eu pressioná-lo, o botão Numpad 0 (KP_0) torna-se 'Menu' (xev reporta), ou 'KEY_COMPOSE' (evtest reporta).
Portanto, gostaria de reescrever permanentemente KEY_COMPOSE para KP_0. Então, mesmo que eu pressione o botão FN-lock no teclado, a tecla 0 do numpad deve permanecer na tecla 0. (sem outros swaps de teclas, apenas a tecla 0 é problemática).
O teclado está em:

O arquivo hwdb é este:
$ cat /etc/udev/hwdb.d/10-my-modifiers.hw
evdev:input:b0011v0001*
KEYBOARD_KEY_3a=leftalt # bind capslock to leftalt
KEYBOARD_KEY_38=leftctrl # bind leftalt to leftctrl
KEYBOARD_KEY_1a=a
KEYBOARD_KEY_1b=b
atualizado via:
$ sudo udevadm hwdb --update && sudo udevadm trigger
Mas isso não funciona. Eu também tentei com evdev:name: , evdev:atkbd: , ainda sem sorte.
Como posso determinar qual é a linha correta de evdev:input:b0011v0001* ?

Tente algo assim:

No meu Thinkpad x240 no Ubuntu 16.04 funciona bem:
cat /etc/udev/hwdb.d/61-ThinkPad-X240-keyboard.hwdb
# ThinkPad X240: switch End and Insert keys (so that when Fn-Lock is enabled, End works without Fn).
