Bug Description
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://
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" "EnableBrightne
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.

status: | Confirmed → Fix Released |
I verified the "can't change backlight (without the xorg.conf option) both in a Unity session and a Classic session with effects. The 'still don't get a notification bubble" was verified only in the Classic session so far, Unity will have to wait.
