Bug Description
I just upgraded my June 2009 MacBook Pro from Karmic to Lucid.
The keyboard backlight control now finally works (as it used to for a while when I first installed... Jaunty I guess—maybe it's the choice of drivers). But I can't turn it off. What I can do is dim the keyboard's internal lighting until it's almost completely gone. If I press the dim button once more after that, it goes back to full-on again.
I would guess that the driver may be confusing "manually disabled" with "automatically disabled because the keyboard isn't being used."

Hello
Is this problem present with the latest updated Lucid's or Maverick's packages?
Thanks in advance
