Desativar o teclado externo de um script

Desativar o teclado externo de um script

Eu tenho uma regra do udev para o meu teclado externo. Posso capturar eventos e, ao executar um script, também posso acessar as variáveis do udev env. Posso desativar o teclado com o udev? Ou devo usar um script para desativar o teclado de outra maneira.

Existe uma maneira de desativar o teclado com o script para executar xinput , mas ele quer um "id". Como posso obter as informações de id para xinput do udev? ou existe outro caminho efetivo?

Rastreio completo ao monitorar o udev para o teclado:

Como ativar o Broadcom wireless BCM 4313 no OpenBSD? Como usar corretamente o Gentoo Linux como um complemento a uma distribuição existente?

score 3 · Answer 1

Usando um script

Um método seria através de um script que é invocado como um script da UDEV. O método que eu usaria seria meu, neste U & L Q & A intitulado: Como desativar o teclado? .

Há instruções muito boas sobre como habilitar / desabilitar um teclado aqui também, intitulado: Desabilitar / habilitar teclado e mouse no Linux .

Exemplo

Você pode listar os dispositivos com este comando.

$ xinput --list
"Virtual core pointer"  id=0    [XPointer]
"Virtual core keyboard" id=1    [XKeyboard]
"Keyboard2"     id=2    [XExtensionKeyboard]
"Mouse2"        id=3    [XExtensionKeyboard]

E desative o teclado com isto:

$ xinput set-int-prop 2 "Device Enabled" 8 0

E habilite-o com este:

$ xinput set-int-prop 2 "Device Enabled" 8 1

Então você poderia colocar os comandos acima em scripts que a UDEV poderia chamá-los.

NOTA: Isso só funciona para desabilitar o teclado através do X. Então, se você estiver em um sistema que não esteja rodando o X, isso não funcionará.

Usando o UDEV

Acho que você pode adaptar uma dessas regras para desativar um teclado baseado em USB usando uma regra semelhante a esta:

BUS=="usb", KERNEL=="hdb", OPTIONS+="ignore_device"

Você precisa determinar as identificações do seu teclado externo. Acredito que todas as informações que você precisa para criar uma dessas regras estão incluídas na saída que você incluiu na sua pergunta.

Bem, você pode desativar qualquer dispositivo USB, neste caso, o teclado. Navegue até o diretório /sys/bus/usb/drivers/usbhid

Listará todo o número do dispositivo USB HID. Para o seu teclado, descubra o número correto e execute o comando:

echo -n 2-1.4:1.0 > unbind

Desvinculará (desabilitará) o hardware USB subjacente Para habilitá-lo novamente, execute

echo -n 2-1.4:1.0 > bind

Aqui, o problema é descobrir o número correto. Mas isso pode ser resolvido sabendo o fornecedor e o id do produto
