Public bug reported:
Since February 1st's 0.15.1 update of the nvidia-bl-dkms package, the backlight
of the screen cannot be changed.
This happens on my Macbook Pro 5-3 but also happens to the 5-5 model according
to http://ubuntuforums.org/showthread.php?p=8756152 , so it doesn't seem very
far-fetched to say that might happen to all Macbook Pros.
Downgrading nvidia-bl-dkms to version 0.15 makes the screen backlight
slider "slidable" again but it has no impact on the screen's actual
backlight.
Using Kubuntu 9.10 64-bit on a Macbook Pro 5-3 with kernel
2.6.31-17-generic (but it does the same on the previous kernels as
well).
