onejay09 66 Posted April 20, 2017 (edited) this post has been updated with the fix that works for my setup and a few others, my laptop is an asus gl702 but this has worked for others with dedicated nvidia graphics also. if your laptop is optimus then this will not work for you. fist find the _DSM method for your Graphics card, ignore any devices that are on PCI0 ie: PCI0.GFX0 your looking for graphics cards Under PCI0.PEG0 ie: PCI0.PEG0.GFX0._DSM or PCI0.PEG0.PEGP._DSM rename the _DSM Method to XDSM and insert this Below Method (_DSM, 4, NotSerialized) // _DSM: Device-Specific Method { If (LEqual (Arg2, Zero)) { Return (Buffer (One) { 0x03 }) } Return (Package (0x34) { "AAPL,backlight-control", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, "@0,backlight-control", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, "AAPL,aux-power-connected", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, "@0,AAPL,boot-display", Buffer (One) { 0x01 }, "@0,display-cfg", Buffer (0x04) { 0xFF, 0xFF, 0x36, 0x00 }, "@1,display-cfg", Buffer (0x04) { 0xFF, 0xFF, 0xFF, 0xFF }, "@0,connector-type", Buffer (0x04) { 0x00, 0x08, 0x00, 0x00 }, "@1,connector-type", Buffer (0x04) { 0x00, 0x08, 0x00, 0x00 }, "@0,built-in", Buffer (0x04) { 0x00, 0x00, 0x00, 0x01 }, "@0,use-backlight-blanking", Buffer (0x04) {}, "AAPL,gray-page", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, "AAPL00,inverter", Buffer (0x04) { 0x00, 0x00, 0x00, 0x00 }, "@1,can-hot-plug", Buffer (0x04) {}, "AAPL00,blackscreen.preferences", Buffer (0x04) { 0x00, 0x00, 0x00, 0x08 }, "AAPL01,blackscreen.preferences", Buffer (0x04) { 0x00, 0x00, 0x00, 0x08 }, "@0,pwm-info", Buffer (0x18) { /* 0000 */ 0x02, 0x18, 0x00, 0x64, 0x90, 0x59, 0x02, 0x00, /* 0008 */ 0x08, 0x52, 0x00, 0x00, 0xA5, 0x1C, 0x00, 0x00, /* 0010 */ 0x00, 0x04, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00 }, "@0,NVMT", Buffer (0x70) { /* 0000 */ 0x0E, 0x03, 0x7F, 0x20, 0x00, 0x00, 0x00, 0x00, /* 0008 */ 0x40, 0x0B, 0x08, 0x07, 0xE0, 0x0B, 0x70, 0x0B, /* 0010 */ 0x90, 0x0B, 0x00, 0x00, 0x3C, 0x07, 0x0B, 0x07, /* 0018 */ 0x11, 0x07, 0x00, 0x00, 0xF0, 0xA7, 0x21, 0x14, /* 0020 */ 0x00, 0x00, 0x00, 0x01, 0xAF, 0x00, 0x00, 0x00, /* 0028 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0030 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0038 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0040 */ 0x00, 0x00, 0x00, 0x00, 0xFF, 0xFF, 0x00, 0x00, /* 0048 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0050 */ 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xFF, /* 0058 */ 0x00, 0x00, 0x00, 0x00, 0xBC, 0x02, 0x01, 0x5A, /* 0060 */ 0x0A, 0x04, 0x00, 0x00, 0x00, 0x02, 0x00, 0x00, /* 0068 */ 0x40, 0x0B, 0x08, 0x07, 0x40, 0x0B, 0x08, 0x07 }, "NVPM", Buffer (0x1C) { /* 0000 */ 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0008 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0010 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0018 */ 0x00, 0x00, 0x00, 0x00 }, "@0,compatible", Buffer (0x0B) { "NVDA,NVMac" }, "@0,device_type", Buffer (0x08) { "display" }, "@0,display-type", Buffer (0x04) { "LCD" }, "@0,name", Buffer (0x0F) { "NVDA,Display-A" }, "@1,compatible", Buffer (0x0B) { "NVDA,NVMac" }, "@1,device_type", Buffer (0x08) { "display" }, "@1,name", Buffer (0x0F) { "NVDA,Display-B" }, "hda-gfx", Buffer (0x0A) { "onboard-1" } }) } we also need to add a pnlf patch to your DSDT Scope (_SB) { Device (PNLF) { Name (_ADR, Zero) // _ADR: Address Name (_HID, EisaId ("APP0002")) // _HID: Hardware ID Name (_CID, "backlight") // _CID: Compatible ID Name (_UID, 0x0A) // _UID: Unique ID Name (_STA, 0x0B) // _STA: Status } } thats all thats needed for the acpi files. we now need to create a backlight injector for your display, use the script below to make the injector and install it to System/Library/Extensions. https://github.com/onejay09/AppleBacklightInjector if your backlight still isnt working then post problem reporting files.

SavageAUS 697 Posted April 20, 2017 I just had to repatch my haswell laptop for this reason (non working backlight) intelbacklight and acpibacklight kexts no longer work nor do the normal dsdt ssdt patches. You need to use an additional kext, (AppleBacklightInjector.kext) a ssdt-pnlf and a config.plist patch. All previously used kexts need to be removed same as acpi patches. Either remove patches or repatch from start without pnlf patching. This is only based on what I did and that was for haswell with Intel graphics (Nvidia disabled via dsdt and ssdt).

onejay09 66 Posted April 20, 2017 I found this info about the PNLF'ish looking piece if code prompt: ACPI INT3406 display thermal driver type: tristate depends on: CONFIG_ACPI_VIDEO defined in drivers/thermal/int340x_thermal/Kconfig found in Linux kernels: 4.7–4.10, 4.11-rc+HEAD modules built: int3406_thermal Help text The display thermal device represents the LED/LCD display panel that may or may not include touch support.

onejay09 66 Posted April 20, 2017 anyone know if this would work?

qaz321xsw 0 Posted April 24, 2017 I've same prob too. brightness backlight work flawlessly on 10.10.5 (up/down FN Keys or slider on display pref). after Sierra 10.12.4 the slider won't work. I tried different version PNLF dsdt patch, and update to AsusACPIBacklight 1.7 kext by Dinesh but still same.

onejay09 66 Posted April 27, 2017 its strange that i cant apply an custom EDID with both clover and via dsdt like above, the display product/vendor id stay the same no matter what, it was an attempt to get the display recognised as built-in with backlight but it thinks its on a displayport, with PNLF in dsdt also. i cant figure it out, maybe its something with 10.12.4 thats stopping me Share this post Link to post Share on other sites

foskvs 485 Posted January 9, 2018 heres my ioreg, i uploaded to my github ioreg thanks mate Just sharing my experience with my desktop. These are the patches i added to my DSDT: PNLF patch taken from a real iMac14,2 DSDT (with GeForce GTX 775M): Scope (_SB) { Device (PNLF) { Name (_ADR, Zero) // _ADR: Address Name (_HID, EisaId ("APP0002")) // _HID: Hardware ID Name (_CID, "backlight") // _CID: Compatible ID Name (_UID, 0x0A) // _UID: Unique ID Name (_STA, 0x0B) // _STA: Status } } Changed _DSM method of Nvidia (PEG0.GFX0) to match iMac14,2 and iMac17,1 ioregs: Method (_DSM, 4, NotSerialized) // _DSM: Device-Specific Method { If (LEqual (Arg2, Zero)) { Return (Buffer (One) { 0x03 }) } Return (Package (0x18) { "@0,connector-type", Buffer (0x04) { 0x02, 0x00, 0x00, 0x00 }, "@0,AAPL,boot-display", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, "@0,built-in", Buffer (Zero) {}, "@0,display-connect-flags", Buffer (0x04) { 0x04, 0x00, 0x00, 0x00 }, "@0,use-backlight-blanking", Buffer (0x04) {}, "AAPL,backlight-control", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, "@0,backlight-control", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, "@0,display-type", "LCD", "@1,connector-type", Buffer (0x04) { 0x00, 0x04, 0x00, 0x00 }, "@2,connector-type", Buffer (0x04) { 0x00, 0x08, 0x00, 0x00 }, "@3,connector-type", Buffer (0x04) { 0x00, 0x02, 0x00, 0x00 }, "hda-gfx", Buffer (0x0A) { "onboard-1" } }) } On this particular patch, i changed connectors to match my actual ones, but i think that you can still have the slider with HDMI (00080000) connectors. On real iMacs with discrete graphics, dGPU is hda-gfx=onboard-1. But probably, the trick is to set the @0 port as "built-in". iMac14,2: This is the result on my desktop with GTX 950: Unfortunately, even on Windows i don't have brightness control, but you might be luckier than me. @onejay09, here's your DSDT (just added the two patches above). @xela, you're the next Edit: I forgot the DSDT...
