draskostar Posted April 27, 2021 Share Posted April 27, 2021 My m6800 is Haswell with HD4600 and I lost brightness control. Before that I made clean install of 11.2.3. Right now I am on OC 0.6.4. I will try with update to OC 0.6.8... Quote Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 27, 2021 Moderators Share Posted April 27, 2021 No issue on my Real MacBook Pro. I also installed it on my HP 840 G3 and have no issue with Brightness Control. FYI, I'm using Lilu 1.5.2 and Whatevergreen 1.4.9 OC 0.6.8 Lilu&Whatevergreen.zip Quote Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 27, 2021 Moderators Share Posted April 27, 2021 Just update my E6430, no issue with brightness control. Using MBP11,1 and serial #, no_compat_check OC 0.6.8 Quote Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 27, 2021 Administrators Share Posted April 27, 2021 Lost brightness control too on my E6230. I have PNLF device built into the patched DSDT; it was something I had added years and years ago; need to remove that and opt for SSDT-PNLF table as posted on, say, Dortania. This may fix the brightness issue. Quote Link to comment Share on other sites More sharing options...
draskostar Posted April 27, 2021 Author Share Posted April 27, 2021 updating Opencore didn't solve problem in my case! brightness control still doesn't work:( Quote Link to comment Share on other sites More sharing options...

Administrators Hervé Posted April 28, 2021 Administrators Share Posted April 28, 2021 Brightness control restored in 11.3 on my E6230 after removing device PNLF from the patched DSDT (it was a very old patch of mine) and adding SSDT-PNLF table (from Dortania). @draskostar watch out with your ACPI settings with regards to iGPU: if you have renamed GFX0 to IGPU in your patched DSDT rather than through bootloader's ACPI device renaming, you'll also have to rename GFX0 to IGPU in SSDT-PNLF too.

draskostar Posted April 28, 2021 Author Share Posted April 28, 2021 @Jake Lo Please find enclosed ioreg + efi: https://drive.google.com/file/d/1nk66YT0EtCO9f8L_uJqXD7bQPY_-eYHs/view?usp=sharing @Hervé If I use my bios device name for HD4600 (PCI0.GFX0) no success; if I rename PCI0.GFX0 to PCI0.IGPU also no success. On 11.2.3 SSDT-PNLFCFL was enough for me (even thought I have Haswell). I also enclosed a file that worked for me before 11.3.

Administrators Hervé Posted April 28, 2021 Administrators Share Posted April 28, 2021 I don't think you should be using that SSDT-PNLFCFL on a Haswell laptop. Given that you rename GFX0 to iGPU in your OC config, I'd have used the regular SSDT-PNLF table, as is, i.e. with references to GFX0. NB: I note that you've not disabled the nVidia dGPU; is that normal? Quote Link to comment Share on other sites More sharing options...
draskostar Posted April 28, 2021 Author Share Posted April 28, 2021 @Hervé With regular you mean that one from opencore’s website? So I then put this SSDT-PNLF into folder ACPI. Should I also enable rename patch in ACPI settings? Why would I need to disable Nvidia? I generally use internal screen (hd4600) but If I connect to external monitor then k4100m is available.
