Just booted with your EFI. Now it shows the option for automatically adjust brightness under the slider but brightness stay the same. ?

same as before. could it be something in my dsdt or my clover settings? I've been trying for a week now to fix brightness.

Still the same behaviour

Also in IORegistryExplorer> PNLF Apple Max brightness = 0x56 shouldn't it be 0x710 for Ivy? I tried Set Intel backlight options with same result

I added PNLF device into dsdt and removed PNLF-SSDT.aml Same behaviour. Hotkeys and slider work but brightness stay the same. One thing that changed is applepanel before it was FT14Txxxx now it is FT16Txxxx.

Hello MaLd0n, I've followed the guide you posted and now I can change brightness with fn+f5/f6 (I was able to do that before with f14+f15). But the problem is that brightness won't change neither from syspref>slider nor from hotkeys. I get this behaviour when I use the latest voodoops2controller ( this kext doesn't recognise my ALPS trackpad so I am using it as a mouse) When I use VoodooPS2Controller-R6RC2.kext (trackpad recognised) when I press fn+f6 I can see brightness icon but it also lowers my volume (fn+f8) In both cases I can't change brightness Bellow is my original Methods for Q11 and Q12 Method (_Q11, 0, NotSerialized) // _Qxx: EC Query { Store (0x11, P80H) If (LEqual (^^^GFX0.DD02._DCS (), 0x1D)) { Return (Zero) } Notify (^^^GFX0.DD02, 0x87) Store (One, ^^FJEX.BLLF) Notify (FJEX, 0x80) } Method (_Q12, 0, NotSerialized) // _Qxx: EC Query { Store (0x12, P80H) If (LEqual (^^^GFX0.DD02._DCS (), 0x1D)) { Return (Zero) } Notify (^^^GFX0.DD02, 0x86) Store (One, ^^FJEX.BLLF) Notify (FJEX, 0x80) }

Hello guys, i've installed Catalina 15.3 on my Fujitsu LH532 and i would like some help in order to finish my build. I'm having a hard time getting brightness to work.
