I'in the process of writing here a detailed description of the manner in which brightness keys operate and how the patches apply and work. Hopefully it'll lit everyone's lantern though it'll be technical given that it's low-level ACPI stuff..

I have replaced also the display with an IPS one and the new one is very bright, so i use it with brightness below medium.

I think it is possible by injecting manual values to pnlf. Never bothered with that though.


How about the audio I was asking before ?

Do you use cocdecommander.kext?

If not , do you have audio working from external speakers after sleep?
