Bug description:
Binary package hint: gnome-power-manager

Many of the recent Apple MacBooks have a large number of LCD backlight levels. The GPM uses XRandR to modify the backlight. However, the gpm-brightness-xrandr smooth brightness function does not take the number of brightness levels into account. On recent Macbooks, this leads to some 20000 brightness-set calls on startup, an activity that takes about one and a half minute. During this time, GPM is not responsive. Attached is a patch that introduces scaled stepping, which fixes the problem.
