Le script dans la règle udev ne s'exécute pas

2010-01-12 2 views

Je cours Ubuntu 9.10 (Karmic Koala) sur un ordinateur portable et voudrait que NumLock bascule automatiquement selon que mon clavier USB est branché (numlock activé) ou débranché (numlock désactivé) .Le script dans la règle udev ne s'exécute pas

Pour ce faire, j'ai d'abord installé le paquet "numlockx". numlockx on et numlockx off fonctionne très bien.

Pour accrocher dans le système de l'appareil, je pensais utiliser udev. J'ai regardé d'autres questions sur StackOverflow et j'ai lu "Writing udev rules". Mais j'ai du mal à faire fonctionner la règle d'udev.

Tout d'abord, voici un exemple de la sortie dmesg:

 
[20906.985102] usb 3-2: new low speed USB device using uhci_hcd and address 6

je udevadm info pour recueillir les informations de l'appareil:

Je crée un fichier appelé /etc/udev/rules.d/usb-keyboard.rules:

 
# Turn on NumLock when keyboard is plugged in. 
ACTION=="add", ATTRS{manufacturer}=="Microsoft", SUBSYSTEM=="input", RUN+="/usr/bin/numlockx on" 

# Turn off NumLock when keyboard is unplugged. 
ACTION=="remove", ATTRS{manufacturer}=="Microsoft", SUBSYSTEM=="input", RUN+="/usr/bin/numlockx off"

J'ai utilisé udevadm test pour vérifier que les règles sont correctes:

Le problème est que lorsque le clavier est branché ou débranché, le verrouillage du pavé numérique ne le fait pas changement. J'ai essayé de redémarrer le service d'udev, sans aucune chance. Mes règles udev sont-elles erronées? Est-ce que je vais à ce sujet dans le mauvais sens?

  1. Je ne suis pas très bien informé à ce sujet, mais je pense serait que l'état du clavier est géré par le X11 « plomberie », qui se trouve à un niveau supérieur à udev, donc ce que vous faites vers le bas il est en train de se substituer. Vous pouvez en savoir plus en explorant les fichiers de configuration au /etc/X11.

  2. Vous pouvez obtenir des réponses plus pertinentes à superuser.com (lien au bas de cette page). Je ne voterai pas pour fermer votre question ici, mais d'autres pourraient le faire.
