Oh yeah, the ever-frustrating brightness, is it not? ._.
So I tried a BUNCH of topics to solve my issue - here are the links to each:
My PNLF device exists, and works, and changes brightness...without a kext. BUT. It stays incredibly dark. Only when my screen wakes, from sleep, it suddenly decides to work again...errrrm, yeah? >.>
So, in the second link, I just recently posted my DSDT, though I realized I have a duplicate of the _DSM method...I might reupload my DSDT at some point and put a link into my signature. Whatever.
Anybody who can give me a working solution would be a hero in my eyes.
Im not too dumb to work with scripts and learned to understand my DSDT. But I am still new on that one.
