Eu tenho um problema com o remapeamento das teclas Fn no meu Dell xps 9370. Software: Arch Linux + Wayland. Eu quero remapear as teclas de brilho para cima / baixo para paginar para cima / baixo, mas não consigo encontrar seus scancodes. Esta é a saída do showkey com a chave do brig up:
#>> showkey --scancodes
kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]
press any key (program terminates 10s after last keypress)...
0x9c
0xe0 0x54 0xe0 0xd4
Saída do evtest:
#>> evtest /dev/input/event13

Meu arquivo hwdb assim:
evdev:*
KEYBOARD_KEY_d4=pageup
Eu tentei 'd4, 53, oe54, 54d4' e outros scancodes, nada funciona. Com outras chaves tudo funciona bem, seu remapeado bem sucedido. Como eu posso encontrar scancodes reais dessas chaves?
