Estoy ejecutando Ubuntu 9.10 (Karmic Koala) en una computadora portátil y me gustaría que NumLock se active automáticamente dependiendo de si mi teclado USB está enchufado (bloqueo numérico activado) o desconectado (bloqueo numérico desactivado).
Para lograr esto, primero instalé el paquete "numlockx". numlockx on
y numlockx off
funciona bien
Para conectarme al sistema del dispositivo, pensé que usaría udev. He leído "Escribir reglas de udev" , pero tengo problemas para que la regla de udev funcione.
Primero, aquí hay un ejemplo de la dmesg
salida:

El problema es que cuando el teclado está enchufado o desenchufado, el estado de NumLock no cambia. He intentado reiniciar el servicio udev, sin suerte. ¿Están equivocadas mis reglas de udev? ¿Voy por esto de la manera incorrecta?
