Public bug reported:
The nvidia-current drivers that have recently become available in Natty
(270.29) work for me in general, but screen backlight adjustment does
not work anymore on my MacBook Pro. Other hardware seems also affected,
e.g an Nvidia GT330M in this thread:
http://ubuntuforums.org/showthread.php?p=10505235
Neither the keyboard keys nor the brightness applet slider works, the
applet icon showing a stop sign as usual when brightness adjustment is
not available.
Adding this to xorg.conf makes it somewhat work again after a reboot.
Option "RegistryDwords" "EnableBrightnessControl=1"
However, this makes only the adjustment work as such; I still don't get
the notification bubble that appeared with previous drivers, and which
still appears in Natty when I use the nouveau drivers.
