For a while, I've been using the nvidiabl drive for brightness control. I
noticed that it correctly detects the max and min values for my laptop and
video card. I was wondering if the nouveau code could somehow benefit from the
work done by the nvidiabl author. The code is present here -

The corresponding thread is here --

relevant updates/changes for my laptop model (VPCCW2) are here -
