[pkg-nvidia-devel] Bug#455477: nvidia-kernel-2.6.23-1-amd64: LCD back-light brightness control not working

[Ronan Keryell]

Package: nvidia-kernel-2.6.23-1-amd64
Version: 100.14.19-1+2.6.23-1
Severity: normal

The nVidia driver does not seem to take into account the up and down
hotkeys to control the brightness of the LCD back-light on a Compaq nw9440.

The only action taken into account is the Fn-F11 hotkey that switch
between manual and automatic brightness control using the ambient light
sensor.

But in manual mode, the back-light is always on full brightness and this
cannot be changed with hotkeys Fn-F9 and Fn-F10.

This behaviour is in the nVidia drivers for 6 months at least.

If I use the free Xorg driver instead, it does work fine on this issue.
