[vrondena]

hi,  someone helps me, even to me brightness bar and key function present but it does not work. I read but I can not, please what to send for help

[onejay09]

What laptop do you have?

Post your dsdt

[vrondena]

Sony vaio vpcs13v9e , i5 - 460m , Nvidia 310m 

now I deleted AppleACPIBacklight from L/E and have AppleBacklightinject

i see bar on sys-pref-display and key show but won't work

 

Archivio.zip

[onejay09]

added correct pnlf and gfx dsm

added backlight level in config

Archivio.zip

for the script to work you need backlight working first with your other backlight method

make sure display is applebacklightdisplay under Display0, not appledisplay

ie:

IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/P0P2@1/IOPP/PEGP@0/NVDA,Display-A@0/NVDATesla/display0/AppleBacklightDisplay

put your applebacklight.kext in vanilla folder

create your applebacklightinjector.kext with this script, install kext

 

PatchAppleBacklight_v2.zip

[onejay09]

you could try this injector instead of making patch, modified for your displayproduct id

AppleBacklightInjector.kext.zip

[vrondena]

I use your dsdt and config.plist ,ioreg show display on applebacklightdisplay under Display0, not appledisplay.

I tried both methods but it does not work, I always have the bar and the key but it does not increase or decrease the brightness. you have other suggestions

[onejay09]

Did you run the patcher?

Did you install the injector?

Post kextstat log and another ioreg with injector

[vrondena]

 the create folder ,kexstat and ioreg,injector on L/E

ciao

Archivio.zip

[onejay09]

why dont you have nvidiagraphicsfixup.kext?

injector is working.

[vrondena]

add nvidiagraphicsfixup.kext on L/E , but not work

[onejay09]

Did you update lilu to latest

[vrondena]

lilu  2017-1207

[onejay09]

theres no such thing as 1207

update and install from here

then post kextstat

https://github.com/vit9696/Lilu/releases

https://github.com/lvs1974/NvidiaGraphicsFixup/releases

if your screen doesnt go black when brightness slider is at minimum then i dont think this will work for your laptop

[vrondena]

update with your link, no way. really strange with Yosemite and El Capitan bar and key work fine

Brightness by bergdesign work 

last try, thank you anyway for the time and help you gave me

kextstat

[onejay09]

all this time you were on el capitan? acpibacklight.kext would be better for you .

next time do your own research and read the forums before asking for help first.

[vrondena]

no, I'm sorry. maybe I have not translated correctly but, as you may have noticed, I am with high Sierra .siri is only on HS,see pictures.

ciao

[vrondena]

for those like me who have the bar / keys and does not work I found this. touch bar disabler. Increase or decrease brightness with the key. control 1 -, 2+ control. works well
now you have to associate with the f5 - f6 keys but I do not know how to do it, I tried karabiner but I can not find it. or with dsdt if someone capable.

yet i told you to install the latest lilu and nvidiagraphicsfixup and you said it wont work. 

if you have multiple installs of mac os then dont use clover/kexts use /S/L/E OR L/E FOR KEXTS

UPDATE THE KEXTS.

ACPIBACKLIGHT IS BROKEN IN SIERRA 10.12.4 AND NEWER YOU NEED DIFFERENT METHOD.
