Bug#728606: general: Keyboard shortcuts for Volume, keyboard backlight no longer work. Shortcut for brightness works, but OSD does not

Title: general: Keyboard shortcuts for Volume, keyboard backlight no longer work. Shortcut for brightness works, but OSD does not

Package: general
Severity: normal

Dear Maintainer,

Since a couple of weeks, on my Asus Zenbook (UX32VD), running Testing, the keyboard shortcuts for the audio volume and keyboard backlight no longer work, and somewhere in the boot cyclus, the keyboard backlight gets disabled.
The keyboard shortcut for brightness does work, but it does no longer give OSD feedback.

Since I have no clue which package is responsible for this behavior, I've filed it against general. Please re-assign to the correct package (and educate me how to find out which package is responsible).

These keyboard shortcuts (Fn+f3, Fn+f4 for keyboard backlight, Fn+f11, Fn+f12 for volume and Fn+f5, Fn+f6 for brightness) used to work correctly until a few weeks ago, but stopped working, most likely because of an apt-get upgrade.
