oldman20 Posted September 2, 2022 Share Posted September 2, 2022 Hello, I've been researching for days about Fn+F11 and Fn+F12 to control screen brightness on Monterey. I tried all my best followed these topics: But can't enable brightness hotkey, current here are all hotkey work native: Fn+Esc (Enable/ Disable Fn key) with On Screen Display OSD Fn+F1, F2, F3 for System Volume level with OSD Fn+F4, F5, F6 for Media control without OSD Fn+PrintScr for disconnect wifi (has no OSD) Firstly follow The Dortania Guide Brightness key work with Fn+S, B. But after tried fix it, it gone too. I tried BrightnessKey.Kext too but still nothing. Here my EFI, DSDT just removed errors, OSCheckFix, kind of keyboard and trackpad with dmesg | grep -i input in Linux and IOReg file with IORegistryExplorer.app v2.1, Could you give some directions on how to solve this, please? Many thank! EFI OC 0.8.3 HackBook Pro.ioreg DSDT.dsl.error.removed.fixOSCheck.zip dmesg_grep_input.rtf.zip Link to comment Share on other sites More sharing options...

Lorys89 Posted September 2, 2022 Share Posted September 2, 2022 add ssdt xosi, add rename osid to xsid and rename _osi to xosi, add kext https://github.com/acidanthera/BrightnessKeys use ssdt pnlf without rename gfx0 to igpu, use ssdt ec, plug. not use dsdt. and you have i2c trakpad, i2c1 - tpd1 add kext i2c and i2c hid put in this order : add bootarg -wegnoegpu if you have dgpu 1 Link to comment Share on other sites More sharing options...
