edit the igpu patch, you should inject the device id as well, I see enable-backlight-smoother uses, but if you do not work the brightness does not make sense .. I were in you, I would make a new patch igpu. https://dortania.github.io/OpenCore-Install-Guide/config-laptop.plist/coffee-lake-plus.html#deviceproperties
yours is a problem of efi / config, this issue makes little sense, write on the forums if you want support.
my igpu dev id is 0x9BC4 so it is natively supported so I think I don't need to inject anther dev id even I tried it before and didn't made any changes on this situation
this notebook contain mux switch may be problem from this also anther person on this guide he complains from this problem also https://github.com/yusfklncc/Lenovo-Legion-5-Hackintosh
this is my ioreg dump and dsdt Archive.zip and this is method q11 and q12 `Method (_Q11, 0, NotSerialized) // _Qxx: EC Query, xx=0x00-0xFF { If (IGDS) { P80B = 0x11 Notify (^^^GFX0.DD1F, 0x87) // Device-Specific } Else { P80B = 0x11 Notify (^^^PEG0.PEGP.EDP0, 0x87) // Device-Specific }
Notify (VPC0, 0x80) // Status Change
}
Method (_Q12, 0, NotSerialized) // _Qxx: EC Query, xx=0x00-0xFF
{
If (IGDS)
{
P80B = 0x12
Notify (^^^GFX0.DD1F, 0x86) // Device-Specific
}
Else
{
P80B = 0x12
Notify (^^^PEG0.PEGP.EDP0, 0x86) // Device-Specific
}
Notify (VPC0, 0x80) // Status Change
}`
i see ioreg, and the pnlf is loaded correctly for cfl +
0xFF7B is correct and _UID is correct.
try this config.plist.zip
thanks for your reply tried it the same problem I think the problem at the level of acpi tables as the same problem on ubuntu also may be problem that Nvidia card control brightness don't know even tried this without disabling Nvidia card but nothing https://dortania.github.io/OpenCore-Install-Guide/troubleshooting/extended/post-issues.html#no-brightness-control-on-dual-gpu-laptops
If your screen is OLED then it's common problem. OLED Screen can't be adjust brightness. Slider and button is working but will no effect in screen. Make sure your internal screen is not OLED
