[Guide] Disabling discrete graphics in dual-GPU laptops

[ladeiko]

Yes... complete nonsense to have kext patches in config.plist/ACPI/DSDT/Patches.



Only from config.plist.



Already answered above.



It works just fine.



With no EC references in _OFF, no need to do anything to _REG.
Read the guide carefully.

Do you mean to use:

Partial hotpatch with patched SSDTs:
- RehabMan Clover required
- patched DSDT.aml in ACPI/patched
- select patched SSDTs in ACPI/patched (must be named as extracted to ACPI/origin)
- add-on SSDTs also placed in ACPI/patched
- renames can still be done with config.plist
- SortedOrder left unspecified
- config.plist/ACPI/AutoMerge=true
- DropOem=false

from post #1?

Should i use "RehabMan Clover"?
Are ACPI/DSDT/Patches applied to AML files placed in C/A/patched?

 

[ladeiko]

Took original DSDT, added calls to _ON/_OFF to _WAK/_PTS/_INI - DGPU is disabled, but still FAN/Wakeup problems.
I dont know what to do....

Yes/Yes/Yes.

Depends on the file...
For DSDT.aml and any AutoMerge SSDTs, yes.
For add-on SSDTs, no.

Read post #1. _OFF calling should happen from SSDT-9.

eg. add an _INI just before _OFF:

Method(_INI) { _OFF() }

Added - still the same result. (little note: after boot before FAN goes crazy i see CPU cores temp about 70-75 celsius - > then fans starts and temp goes down to ~35 celsius - maybe this is important info).

MacBookPro14,3 is a poor choice. Use MacBookPro14,1 or MacBookPro11,1.

Your USB configuration is wrong... see guide:
https://www.tonymacx86.com/threads/guide-creating-a-custom-ssdt-for-usbinjectall-kext.211311/

DSDT.aml has no patches... no idea why it is in ACPI/patched...

APFS not recommended... try installing to HFS+J instead.
And you might want to introduce kexts/etc one-by-one, such that you might determine what is causing your fan isseu.

FakeSMC sensor kexts not necessary... Try without.

Your kextcache output proves kexts are not installed correctly.
All kexts you need must be installed to the system volume.
Read post #2 of the Clover guide for details:
https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

Also, as per guide... you should try calling _PS3 instead of _OFF.

Guys, I'm having problems with my new laptop, Acer Aspire A515-51G-70PU.

It has the NVIDIA Optimus 940MX and I've tried everything to disable it. I'm stuck at the installer boot, It hangs on "Service only ran for 0 seconds".

I'm sure it's a discrete graphics card issue... Attached are my DSDT and SSDT files that I extracted using Clover. Please, help me!

Disabling the discrete device is something you should do post-install.
For install, you can use spoofing.

I have the following, any ideas on how to disable the AMD Graphics in my laptop I get stuck at the install screen for

.com.apple.WindowServer

Processor: Intel Core i7-3635QM (2.4GHZ Quad Core)
Chipset: Intel HM76

So the spoofing dsdt is mean for install only ? (Tonymac said this is the third alternative)

I already thru the post installation, so i still need to patch dsdt and ssdt with ini,off,reg patch?
And remove my spoofing ssdt on clover patched acpi folder , and changed with full dsdt and ssdt patched?
if using this threads methods then no need to use acpi hotpatch like ssdt-igpu.aml and ssdt-ptswak.aml ?

Where is better? patched using this threads, or So using full hotpatch clover here to disable nvidia optimus dsdt via config.plist and ssdt hotpatch https://www.tonymacx86.com/threads/guide-using-clover-to-hotpatch-acpi.200137


your ssdt-igpu.dsl is using 5916 for uhd 620, s410 uhd620 is 5917. it is ok using the ssdt-igpu? or i need to change it the dsl

there is a s510 asus thread using display overrides. what is for?

How to know qe ci enabled? Ioreg?
