With that DSDT the brightness slider appear in syspref. When I lower the slider nothing happend. Still can't control the brightness

[ref]FCU4ever[/ref], no idea since i never used asusFN kext. I had a working slider and Fn keys just by using voodoops2controller and dsdt patch for my old laptop with nvidia graphics http://Olarila.com/forum/viewtopic.php?f=28&t=8768

And with wich patch you’ve got the brightness slider?

[onemanosx]

[ref]FCU4ever[/ref], similar patch as in your dsdt

Add this patch to the latest DSDT that I had uploaded and remove AsusFN kext from your S/L/E or L/E or Clover/Kexts/Other. Rebuild permissions and reboot.

(might also need to rebuild permissions again and reboot 2nd time)

 

into method label _Q0E replace_content
begin
// Brightness Down\n
Notify(\_SB.PCI0.SBRG.PS2K, 0x0205)\n
Notify(\_SB.PCI0.SBRG.PS2K, 0x0285)\n
end;
into method label _Q0F replace_content
begin
// Brightness Up\n
Notify(\_SB.PCI0.SBRG.PS2K, 0x0206)\n
Notify(\_SB.PCI0.SBRG.PS2K, 0x0286)\n
end;

 

In some cases, slider wont adjust brightness. But working FNkeys will adjust the brightness accordingly.

If this doesnt work, then I dont know.

I've patched the DSDT you've send me. Copied the DSDT to Clover/ACPI/Patched. Removed AsusFN kext. Rebuild permissions, reboot -> Slider appear and the FN buttons let the slider go up and down but the brightness isn't going up or down. Rebuild permissions again and reboot. Still no luck. Also the other FN buttons don't work without Asus FNkeys kext.

[ref]FCU4ever[/ref], maybe you need to mod the AsusFN kext plist.

I cant help with that. Never used it. On a good note, the slider and brightness keys are working though it didnt change the brightness

That is true. Many thanks for your help and I will look further

I've got it working I only needed to generate an AppleBacklightInjector.kext with this guide https://www.tonycrapx86.com/threads/native-brightness-working-without-blinkscreen-using-patched-applebacklight-kext.121031/

After installing the generated kext I have full brightness control.
