Merci pour l'info, je regarderai ça à l'occasion mais pour le moment je ne fais tourner ni dbus ni hal donc bon ^^
Une question néanmoins, est-ce que ça gère le démontage propre des disques durs externes ? J'entends par là avec démontage et mise en veille du disque. Actuellement j'utilise ce
script.
Bon, tu n'as toujours pas hal&Cie, mais au cas ou pour les autres, j'ai adapté le script pour pouvoir le mettre dans les options de ROX à la place de la commande umount : ( ROX -> Options -> Action Windows -> umount command : path/to/my-halevt-umount )

Unmount and suspend a usb device, so you can safely remove it.
Usage:
[VERBOSE=true ]$0 /mount/point

Use this script with your file manager:

It's safe to remove the USB device now but better can be done. The
power level control file $POWER_LEVEL_FILE
doesn't exist on the system so I have no way to put the USB device
into suspend mode, perhaps you don't have CONFIG_USB_SUSPEND enabled
in your running kernel.
