Summary of the thread: Asus U50 provide a keyboard backlight, I didn't know how to expose that to userspace. Matthew told me that in Apples, the SMC driver expose the keyboard backlight as a led. Then Alan found hald-addon-generic-kbd-backlight to plug the led subsystem and org.freedesktop.Hal.Device.KeyboardBacklight interface. What we want to do is change the brightness when KEY_KBDILLUM* is pressed. I believe that we need a keyboard backlight addon that respond to KEY_KBDILLUM* and update the corresponding /sys/class/vendor:color:kbd_backlight. -- Corentin Chary http://xf.iksaif.net - http://uffs.org -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
