Nvidia backlight control on HP OMEN ce003na

[Jacie950]

Hello all!

 

I have an HP OMEN ce003na here running macOS High Sierra, and I am trying to fix the Nvidia brightness controls. Since my laptop hasn't got Intel graphics, this is a tricky problem.

Also, my battery status doesn't work, so any help with that is very much appreciated.

 

My specs:

Motherboard: HP 8390 40.26

CPU: i7-7700HQ

GPU: NVIDIA 1060 6 GB GDDR5

Hi, you need to go here to find what you are looking for...

Same boat here. Have an Helios 500 with GTX 1070 only and unable to enable brightness control. I've also tried all the things mentioned in:

 

Sadly nothing works.

Hello!

 

If your display does not show up as an internal one, you dont get the Applebacklightdisplay, which you need to get the brightness slider showing up and working. Then you can look in your acpi tables for the brightness methods. For this you have to create a correct gfxstring with gfxutil and looking in the original ioregs of MBP 9,2/10,2, the last ones with nvda kepler mobile cards. Injecting your card wth clover option or Lilu + Weg (or even your card is without any injecting recognized) comes to late in the boot sequence to get it showing up as an interal card. Therefore you get only an AppleDisplay showing up in Ioreg as display, giving no brightness control.

 

To make mobile Nvda fermi cards working with an efistring, was not so hard til 10.10.x. Then Apple has changed some things in the gfx (display) management. With 10.11 up, i have gotten only kernel panics with the created efistring at loading of nvdastartup.kext. In additon to this the usb 3 ports on the XPS 17 L702X 3D refused correctly working because of NEC chipset. Therefore i have left the trail with NVDA mobile cards.

 

Have fun.

Maybe you can help if I provide the ACPI tables dump? I've tried to patch DSDT with PNLF and SSDT with the right _DSM method. Screen gets properly detected as AppleBacklightDisplay when checking with IOReg, but sadly screen remains black (good that I have working external display on DP). Is there anything I can provide to debug this issue further?

 

Acer Helios 500 has no IGPU and only GTX 1070 dGPU.

 

EDIT: i'm using latest Nvidia Web Drivers, so QE/CI is absolutely fine. Brightness control is the last thing which doesn't work, but it's also the most annoying non working feature since the backlight is at full blast. Attached my patched DSDT and SSDT.

Hello!

 

Is sleep on lid close working on your device? If yes, close lid and let device sleep. If you then open the lid, device should awake and turn on backlight on internal lcd. If lid sleep does not work, let your device with menue or powerbutton sleep, on wakeup it should also fire up backlight on internal display.

 

if this works, then the first to do, is to patch AGDP.kext.

Which smbios are you using?

Please report back.

 

Have fun.

I'm tried iMac14,2 and Macbook pro 15,1 as these hardware seem to be the most related to the Helios 500 hardware. I have already tried closing and reopening the lid, it has no effect. Here is my config.plist.

It's been almost 3 weeks since i'm fiddling with this without success, trying various ACPI patches. I'm sure the answer is not so far, but somehow I can't figure out what's wrong as i'm not an ACPI programming expert. Also attached:

 

- an IOReg export (when no ACPI patch applied);

- My ACPI work folder which contains a Makefile to easily decompile, edit and recompile ACPI files using maciasl from Rehabman.

Menu or powerbutton sleep have also no effect? You must reach the real sleep state.

[vanadium]

When trying to sleep the computer from the menu, it doesn't sleep and wakes up immediately to user logon screen. Closing the LID shuts off the internal screen, that's it. It doesn't do anything else. The computer is still running on my external display.

Are you on 13.6?

 

[vanadium]

Yes, High Sierra 10.13.6.

 

PNLF patch in DSDT:

I suspect either pwm-info or NVMT isn't right for my GTX 1070.

Tried so far:

 

- Various PNLF patches with or without _BCM, _BQC, _BCL and _DOS methods mapped,

- _DSM method patch in PCI0.PEG0.PEGP.

 

IOReg reports the screen as AppleBacklightDisplay, but no brightness slider is available. I have a patched AppleBacklightInject (patched with proper display id, double checked with IOReg) in /L/E but somehow doesn't seem to load when checking kextstat. (even when rebuilding cache with "sudo kextcache -I /")

 

The screenshot shows both screens. Please not the internal display is running on "Display-C" port with an internal eDisplayPort connector.

Here is an IOReg with ACPI being patched with patches mentioned above. Screen stays stuck on the Apple logo (mouse is visible). If I change resolution and/or refresh frequency it remains black after (no backlight). External display (Display Port) is fine. Internal display is properly recognized as internal, although with macbookpro 15,1 SMBios it strangely looks like an iMac.

Result of kextstat:

Altough AppleBacklightInjector.kext is present in /L/E. Rebuilding kext cache gives:

Hello!

 

I have removed the AGDP patch in your config.plist above with SMB MBP 15,1 and edited the confi.gplist of AGDP.kext with device ID of MBP 15,1.

 

Try with the attached files, if you get backlight on the lappy screen. Kext to install in S/L/E. Backup the vanilla one.

EDIT: installed the config.plist provided and booted on it. No brightness slider and screen is still stuck on the Apple logo with progress bar. Is there anything else I can provide you to help?

If you can easy  remove them and be able to boot without them.

[vanadium]

Wait, i've not installed the kext. Going to backup the existing one and install it, then reboot and let you know. Going to use kext wizard and clearing kext cache.

 

EDIT: Things have changed. Now it's no longer stuck on Apple logo but instead just a black screen on internal display on boot.

 

Modified AppleGraphicsControl Kext installed in /S/L/E with kext wizard and kext cache cleared. Kext is loading on boot:

No brightness control available.

Backlight kext being loaded:

My patched AppleBacklightInjector kext is s

till not loading somehow, even while being inside /S/L/E. It still complains about the kext signature.

 

EDIT:

 

I modified the ACPI patch mentioned in the topic to fit my needs. They map @0 and @1 displays, I changed @1 to @3 because my internal display runs on display-C.

Try this config.plist,with chaned values in rt-var and remove  backlightinjector.kext. At first we have to bypass the black screen.

config.plist.zip

[vanadium]

Done:

- Remove AppleBacklightInjector kext from /S/L/E,

- rebooted with your config.plist,

- AppleGraphicsControl kext still in /S/L/E.

 

We have made progress! Brightness slider appeared, internal screen stuck on Apple logo again. Brightness slider has no effect. Attached screenshot and IOReg.

EDIT: internal display, although being black, is on. Backlight is running but nothing is displayed. Not sure if it helps.

Okay, navitage in finder to S/L caches and put all files in this folder to trash. They all will be rebuild . Reboot, at clover bootscreen, press space and select with injected kexts. Are you using lilu + weg?

[vanadium]

Here is my entire EFI folder. Using Whatevergreen + lilu. Let's reboot with injected kexts! I would like you to thank you for taking the time to get this done. I hope this will lead to a working guide for the Acer Helios 500 once we're finished with fixing this issue.

When booting with "Injected Kexts" option:

 

- internal display only works (no external display),

- Nvidia Web Drivers report being on macOS driver (thus no QE/CI),

- Nvidia card reported as 8Mb card,

- No brightness control slider available,

- Display being detected as AppleDisplay only.

 

Attached screen and IOReg.

Have you switched off with boot argument the adgp patching by weg?

 

[vanadium]

No. Just remove the caches and used the config.plist you provided, as well as selecting "Injected Kexts" on boot. Now, even on reboot, the macOS driver is selected (instead of Nvidia WebDriver one).

 

EDIT: rebooted with "agdpmod=ignore" but internal display is stuck on apple logo and no external display works in that case. Rebooted again by removing this option, and Nvidia Web Drivers have kicked in again.

 

So we have:

- Nvidia web driver working,

- Brightness slider but no effect,

- Internal display stuck on Apple logo (but mouse can be moved on it),

- Any change to resolution / refresh rate on internal display renders it black forever.
