Apple Backlight Injector Brightness not saved

Status
Not open for further replies.
I have now flashed my BIOS back to an older Version and I can boot now again with OsxAptioFixDrv-64.efi successfully. I will then also do an CMOS reset again.
 
I did now again an CMOS reset and bootet my System with EmuVaribleUefi-64.efi from the begininng but the Brightness is still not saved and back to default when I do an restart. Do you any other solution for this?

No further ideas for you. Suggest you debug your situation to find the problem.
 
Could it be that something is wrong with the Kext File that the Brightness isn't loaded correctly from the NVRAM Values or that the Monitor isn't fully supported or could it also be that the Graphic Incection of Clover breaks something? I also tried to boot with the SSDT-IGPU but this wasn't successfull.

You didn't provide any "Problem Reporting" files, nor any details on the investigations you've done.
 
I have tried now to boot the Laptop without and without Inject Intel and IG-Platform if maybe this will overwrite some values from the Backlight but the boots failed with the Message "Graphics driver failed to load : could not register with framebuffer". It also failed with the SSDT-IGPU.aml from your Hotpatch Repository with the same error message.

When I Inject Intel and the ig-platform then I can boot successfully and without the SSDT-IGPU.aml.
I see also when I change the Brightness that the NVRAM Variable is different that it were before the Brightness Change but it still get reverted at every boot. I have now attached my current Clover Folder and also to Boot logs how they was before and after the reboot and the Values are changed for the backlight-level.

Can I maybe use the AppleBacklight Patch Script from you or do this not work in 10.12.5?

SSDT-IGPU from my hotpatch injects ig-platform-id 0x191b0000 for your device-id (0x191b).
It is different from what you're using here, 0x19260004.

According to ioreg (and kextcache output), you did not implement backlight control correctly.
See guide:
https://www.tonymacx86.com/threads/...rol-using-applebacklightinjector-kext.218222/

Also, all kexts you need should be installed to the system volume.
Read post #2 of the guide:
https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/
 
i have same issue.
first put 0xffff in SystemParameters-BacklightLevel

then tell me, you get max-brightness.

i suspect clover bug.
in nvram.plist, brightness value has brightness before restart.
but restart, always hold 80% brightness. nvram.plist is no problem. just clover can't properly read from latest nvram.plist.

it is not happen all laptop, some laptop has this issue. dell in my case.
 
When I inject the SSDT-IGPU.aml from you without any modification and also with the Inject with ig-platform 0x191b0000 I get no graphic acceleration and the Error Message "Graphics driver failed to load : could not register with framebuffer".

can you tell me what I did wrong by the Installation of the Backlight Control because I don't find any error what I have done wrong.

Is it not better to have the kexts in the Clover Folder that they will also work after an Upgrade or something?
