Display backlight Driver for Asus Notebooks

[hoanglan87]

hi EMlyDinEsH,

 

Could you please check why the brightness slider didn't work for me?

My hackintosh is ASUS K56C, cpu core i5 3317U with NVIDIA graphic (disabled) with Yosemite 10.10.

 

Thanks.

Your model does not work with DSDT patch as its not enabled in bios, so you don't need this driver. Use either default Apple driver with just regular PNLF patch or ACPIBacklight using rehabman kext and patch.

Thanks for your reply. I'll try PNLF patch.

Hi EMlyDinEsH,

 

Could You help me a bit - I have Asus G750JW - everything is working except display backlight. I know this laptop

is not on Your list but maybe You could give me some hint. I get keyboard backlight to work with RehabMan patch, only

with display I have problem and struggle with it for last 2 days.

Some spec:

i7-4700HQ

only NVIDIA GTX 765M

Should I look for PNLF patch, specific kext or something else ?

 

Thanks

Let me see your DSDT and IOreg file. 
 
PS: i'll won't be available until 20th as I'm traveling right now. I think i can help you with my kexts for both keyboard backlight and display brightness. So wait for some time and give me reminder then by PM.

Hi,
 I'm not sure if you're still able to support with this but I'm having some issues getting this working on a UX31A with 10.10.4
 Attached is my DSDT.
 I'm unable to adjust brightness with either the function key's or the slider in display preferences.
 

Thank you

Sorry for late reply and I'm still supporting this but took a long break very recently due to busy life. And I've checked your model and can confirm that my driver wont work with your model due to lack of native asus brightness controls in DSDT, so you have to try ACPIBacklight driver: https://github.com/RehabMan/OS-X-ACPI-Backlight using needed PNLF patch (google it).

Hi Guys,

 

How should I apply the ASUS Acpi Backlight PNLF NVIDIA Patch G50, when I do not have a GCBL Method in my DSDT?

 

    Method (_BCM, 1, NotSerialized)
    {
        Store (\_SB.PCI0.P0P1.VGA.GCBL (Arg0), Local0)
        Subtract (0x0F, Local0, LBTN)
        \_SB.PCI0.SBRG.EC0.STBR ()
    }
