this's just a virtual regulator like shades..... screen brightness doesn't decrease on the hardware...

Of course it won't work because driver is need for it. But brightnees can be controlled by keys such as Fn+->/<-.
Good driver just does not exist for ATY card.

Hey ivik,

 

I am working on a Dell XPS L702x with 3D.... I have attempted your kext several times over the past 2 years with close success (whereas I could get values and set values using the brightness cmd but nothing would change until the system was rebooted) but now I've finally got it!

 

At first I thought it was my weird modifications to my DSDT, but thank god it wasn't!

 

It turns out Enoch's revision of the Chameleon bootloader had a flag to "EnableBacklight=Yes"

 

Enoch is a bootloader dedicated to improving systems with Nvidia graphics.

 

So that magical flag allows your kext to work!! :D

 

Hope this helps other Nvidia users!

Many thanks to ivik for their work on this! I'm sure it's been helpful to many...just not for me :(
 
I'm in progress of getting most of my HP Envy 17t-j000 Quad working. I'm pretty sure I messed something up in my DSDT for this. Unfortunately though, I honestly don't know why it doesn't work. I haven't had much time to figure it out either. I'm a bit confused on the max brightness > 0 thing too. Can't find it in my ioreg and I looked everywhere I thought it would be. I had to assume I didn't have it but I wanted to try the kext anyway.
 
_BCM _BCQ & _BCL aren't listed anywhere in my DSDT. Again, at least I couldn't find them. I added them to my LID0 anyway, however, I get new compile warnings for leaving them blank {}. If I use this DSDT, it KPs on GenericBrightness for CPU6 or something (goes by too fast to read, then reboots)
 
I've since reverted my DSDT so I can use my system again. I haven't tried any of the other listed kexts or methods yet because i'd like to have some kind of "native" setup if possible. Would anyone be so kind as to check what I might have done wrong? My zip includes my current, working DSDT and the broken, edits above I attempted. Attached File  GenericBrightness_failure_HP_Envy_17t-j000_Quad.zip   64.91KB   1 downloads
 
Much appreciated! Thanks in advance. If any further info about my system is needed, please refer to my WIP thread here: http://www.insanelym...on-mlmavericks/

Hi,

Did you try to get native brightness control? For me three things did it: modifying DSDT (GPU section, PNLF), ApplePanelA legacy kext and compatible gfx. Read this, may'll help.

Thanks THe KiNG for a very instructive explanation.
Also as you i get ApplePanelTable under PNLF device but if i use LegacyAppleBacklight containing my lcd panel's productID key in ApplePanels dict. For the start copied into it values from MBP6,1 panel's key. Don't know how to get AppleGraphicsControlBacklight loaded instead of AppleBacklight like in real MBP6,1. Maybe changing/injecting panel's vendor/product IDs resolve it? But how/where? Flashing eeprom? Not prefer (don't know how).

i dont know if you are still here,

but i have been found the way's to use the ApplePanel and you can look what i've written

Hi,

I'm using this method from years. I don't remember if I described/posted it somewhere, may be here or there (Samsung R Series Notebooks) ;)

BTW nice tutorial.

To adjust brightnes levels I edited values in ApplePanelA table related to my LCD panel (inserted before). You must know that pwm-info entry (GPU section in DSTD) influences brightness levels, I think it's a InverterFrequency (same two bytes as in APPLE00,InverterFrequency). Be careful using/editing pwm-info key, you may mess your stuff up! You do this on you own risk!
