No meu laptop, a ativação da repetição automática ( xset r on ) não funciona. Ao verificar a saída de xev , parece que o motivo pelo qual o autorepeat falha é porque outra tecla está sendo pressionada intermitentemente (embora eu não esteja pressionando nada), o que cancela a repetição automática da tecla pressionada no momento. Quando nenhuma tecla está sendo pressionada, os seguintes eventos são gravados repetidamente de forma consistente:
KeyPress event, serial 33, synthetic NO, window 0x1200001,
root 0x123, subw 0x0, time 1652400, (-509,794), root:(455,814),
state 0x0, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
KeyRelease event, serial 33, synthetic NO, window 0x1200001,
root 0x123, subw 0x0, time 1652400, (-509,794), root:(455,814),
state 0x0, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
Parece que uma tecla com o código de tecla 221 está sendo pressionada, mesmo quando não está.
Assim, é possível desabilitar completamente um keycode de tal forma que o xorg não receba o sinal de keypress daquele keycode? Ou é possível tornar as teclas autorepeatadas quando pressionadas, independentemente de outra tecla ser pressionada?
Atualização:
Depois de executar sudo evtest , parece que quando a saída oculta está vindo de
/dev/input/event11 PEAQ WMI hotkeys
Nenhum outro dispositivo de entrada parece enviar eventos quando nada é pressionado. O Autorepeat funciona ao verificar eventos de teclado no evtest.
A saída completa de xev em execução por alguns segundos quando nada é pressionado:

Parece que este é um bug introduzido com o kernel 4.13, de acordo com o erro do bugzilla Redhat # 1497861 .
Descobri que descarregar o módulo peaq_wmi também serve como solução alternativa; parece que alguém já enviou um patch para corrigir o problema.
(Para descarregar o módulo peaq_wmi , pode-se emitir o comando sudo modprobe -r peaq_wmi .)
Acontece que desabilitar as teclas de atalho do PEAQ WMI corrige isso. Desativei as teclas de atalho do PEAQ WMI primeiro verificando xinput list , para encontrar o id:
[email protected]:~$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Dell Dell KM632 Wireless Keyboard and Mouse id=11 [slave pointer (2)]
⎜ ↳ Dell Dell KM632 Wireless Keyboard and Mouse id=12 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics 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)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ Dell Dell KM632 Wireless Keyboard and Mouse id=10 [slave keyboard (3)]
↳ Lenovo EasyCamera: Lenovo EasyC id=13 [slave keyboard (3)]
↳ Ideapad extra buttons id=14 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=15 [slave keyboard (3)]
↳ Dell Dell KM632 Wireless Keyboard and Mouse id=18 [slave keyboard (3)]
↳ PEAQ WMI hotkeys id=17 [slave keyboard (3)]
Nesse caso, o id é 17. Em seguida, no .xinitrc, adicionei xinput --disable 17 ou o ID que está causando problemas, o que corrige o problema.
Eu tenho o mesmo problema no elementaryOS após a última atualização do kernel. Eu postei sobre isso aqui . Usando uma das respostas, sudo modprobe -r peaq_wmi resolveu o problema para mim.
EDIT: Adicionando xinput --disable 17 em .xinitr fez não resolver o problema permanentemente para mim, então eu corro o comando acima após cada inicialização. Eu tenho o Lenovo Yoga 500-14IHW em elementaryOS.
Além disso, esse bug não é relacionado ao Arch linux, portanto, marque-o como tal, para que mais pessoas encontrem a solução para esse problema.
