[Bug 1274398] [NEW] Backlight brightness adjustment and Fn keys do not work on Asus G75VW series laptop on Ubuntu 12.04 LTS

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

The backlight brightness adjustment through the Brightness and Lock
settings and also through the use of the function keys on the Asus G75VW
model laptop do not function. Changing the brightness with the slider in
the Brightness and Lock settings yields no change in brightness, and
using fn+F5 and fn+F6, which are the buttons used as hotkeys for
brightness adjustment, also produce no change in brightness.
