Detecta teclas Fn-F1 e Fn-F2 no MacBook Pro

Question

Eu quero mapear fn-f1 para a execução de um comando no MacBook Pro 11,5. O problema é que atualmente o Fn-F1 não é detectado como nenhuma chave. Eu não sei como vinculá-los a (XF86MonBrightnessDown) e ((XF86MonBrightnessUp)

Eu tentei Algumas chaves não são detectadas no meu teclado (teclas multimídia?) pelo xev ou xbindkeys ou keytouch: como detectá-las? mas depois de instalar isso, o xev ainda não consegue detectar Fn-F1 e Fn- F2.

Eu segui o link para definir a tecla F1-F12 para funcionar como no laptop normal. Esta etapa faz o Fn-F1 em vez do F1 indetectável.

Add following line to /etc/modeprob.d/hid_apple.conf:
    options hid_apple fnmode=2

Run the following command:
    sudo update-initramfs -u -k all

Encontrei códigos de verificação para fn-f1 e fn-f2

1. mude para o console com alt-ctrl-f1.
2. showkey -s
3. pressione e solte fn-f1 e fn-f2. registrar scancodes

Resultado:

Fn-F1 pressed
    0xe0 0x4c
Fn-F1 released
    0xe0 0xcc
Fn-F2 pressed
    0xe0 0x54
Fn-F2 released
    0xe0 0xd4

setkeycodes não pode vincular nenhum scancode ao código da chave

Cannot bind numlock to key_A:
$ setkeycodes 45 30
setkeycodes: failed to set scancode 45 to keycode 30: ioctl KDSETKEYCODE: Invalid argument

xev não consegue distinguir Fn-F1 e Fn-F2
