Mario, just did some testing in order to verify everything. I completely removed pommed, so this deamon is not interfering anymore with gnome-power-manager.
The results: * The module correctly detects the version of my macbook * Without the option use_gmux, the 16 levels are back again. This provides the user with a stable, working solution. * With use_gmux=1 (and debugging enabled), the brightness of the backlight is adjusted by increments or decrements of size 1, just as you expected. So from a technical point of view it is working, from a user point of view it is alas not workable ;-) On Thu, 28 Oct 2010 15:41:50 -0000, Mario Schwalbe <[email protected]> wrote: > Actually it is a bit different: Version 0.25 of mbp-nvidia-bl added > (and enabled by default) a new approach of setting the backlight on > MacBook Pro 6,1 and 6,2, that has been reported to work.
