Brightness problem - Fujitsu LH532 (10.15.3)

[skunkone]

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.  I've tried 2 methods both failed. 
1st method  Clover-> Add PNLF & Intel Backlight  - Intel Backlight Max. 
2nd method SSDT-PNLF & WEG

I can see slider in syspref but its not working

Working: 
Ethernet
USB
Sleep 
Graphics Accelaration 
Battery 
Trackpad
Camera (Disabled for now cause it breaks sleep)

Not working:

Backlight - brightness

Thanks in advance for your help.

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)
                    }

try this PNLF

into_all device label PNLF remove_entry;
into scope label _SB insert
begin
Device (PNLF)\n
        {\n
            Name (_HID, EisaId ("APP0002"))  // _HID: Hardware ID\n
            Name (_CID, "backlight")  // _CID: Compatible ID\n
            Name (_UID, 0x10)  // _UID: Unique ID\n
            Name (_STA, 0x0B)  // _STA: Status\n
        }\n
end

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. 

 

[skunkone]

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

[MaLd0n]

ye, try with 14 = 0x0E

Name (_UID, 0x0E) // _UID: Unique ID\n

[skunkone]

Still the same behaviour
