Powerbook5,6: keyboard's backlight



Hello!

I have a powerbook5,6 15" recently bought. Mi message is about keyboard backlight ilumination which does not like to work. I have installed pbbuttonsd | gtkpbbuttons-gnome | powerprefs. I have the kernel modules to run sensors (i2c-dev and some others). When running powerprefs, in the "bulb tab", the "keyboard"
and "Autoadjust" tabs appear in grey (not accesible). How can I do to run keyboard's backlight? I read about the daemon lmud but I don't know how to get and install it.

Can anybody help me? I enclose my /etc/pbbuttonsd.conf

Regards.
