[Bug 551436] Re: Can't turn keyboard backlight off

It works again in the sense that I seem to be back to the original
problem: I can dim the keyboard lights but I can't quite turn it off
(except by waiting for it to turn off of its own accord).  When I try to
dim further, it just goes back on full again.

Am running the apport-collect now.

** Tags added: apport-collected

** Description changed:

  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."
