Now I made my nvidia injected via DSDT but still no brightness.
Please help.
This is my DSDS.dsl http://www.mediafire...1wsa99272kdb2np
I can't attach it here because of "Internal Server Error"

I tried to edit _BCM method but nothing. The brightness on max. Can't change it. (((

[Onishi]

Guys, there are my methods. How should I change it to make brightness control work ?

 Method (_BCL, 0, NotSerialized)
						{
							Return (Package (0x0A)
							{
								0x4B,
								0x23,
								0x0A,
								0x19,
								0x23,
								0x32,
								0x3C,
								0x4B,
								0x5A,
								0x64
							})
						}
						Method (_BCM, 1, NotSerialized)
						{
							Name (BRIT, Buffer (0x08)
							{
								/* 0000 */	0x0A, 0x19, 0x23, 0x32, 0x3C, 0x4B, 0x5A, 0x64
							})
							Store (0x07, Local0)
							While (Local0)
							{
								Store (DerefOf (Index (BRIT, Local0)), Local1)
								If (LEqual (Arg0, Local1))
								{
									Break
								}
								Decrement (Local0)
							}
							Acquire (MUTS, 0xFFFF)
							LSMI (0xA2, Local0)
							Release (MUTS)
						}
						Method (_BQC, 0, NotSerialized)
						{
							Name (BRIT, Buffer (0x08)
							{
								/* 0000 */	0x0A, 0x19, 0x23, 0x32, 0x3C, 0x4B, 0x5A, 0x64
							})
							Acquire (MUTS, 0xFFFF)
							Store (LSMI (0xA3, Zero), Local1)
							Release (MUTS)
							Store (DerefOf (Index (BRIT, And (Local1, 0x07))), Local0)
							Return (Local0)
						}

^^^in that same thread the OP posted a fix for the brightness that works great
i used it and had no problems
try it
it's an executable. run it and reboot. no need to edit the DSDT
that's it

I have the slider but the brightness changes in a non linear manner! Has anyone else had this issue?

Maybe some of you guy faced the problem when no BCM BQC methods defined in dsdt? only BCL method. my desktop all-in-one pc have internal lcd and as i understand device named JAN0100 ( HP ACPI AND OSD Buttons) controlling brightness. is there a slightest chance to get methods from JAN0100 and adopt them for traditional BCM BQC? with fake/blank methods added to dsdt this влучdoesn't loads

Hi, I have samsung rf511 s02 and applied the PNLF method to get the slider, but it's not changing the brightness at all.
The Fn brightness keys don't work at all.

Also there's no LCD section on my dsdt.

I attach my dsdt

Can you help please?

Hey, thanks for all your work! This helped me.

Now I want to perfect the remapping of my keyboard.

Can you explain just like one example of what this is?


0x91,// e0 6f acer down

what is the 0x91? and what is the e0 6f?

Where are you assigning a function to that key?

And what does dead key mean?

Thank you Ivik!

PLEASE HELP ME
I JUST NEED TO INCREASE BRIGHTNESS !!!!!!
CURSOR RUNS BUT THE BRIGHTNESS IS LOW

[Ralf Prog]

Hi, first of all I want to say thanks to all of those who have shared their knowledge to get this working.

So far I am able to control brightness on my laptop, the slider shows up and all, but I still have one problem and I hope someone can give me some insight. When I boot OS X 10.8 for the first time the screen looks dim and this is the max value when I check the slider  but when I wake my laptop from sleep the brightness increases at the right level, but how can I keep it at this level without putting my laptop to sleep every-time ? do I have to change some hex values in my DSDT ? what can I do to fix it ?

Thanks !!!

this is my ioreg

Hi everyone,
i'm running Snow Leopard on a Vaio VGN-SZ1. Graphics is Intel GMA950 using framebuffer 1.4.20
Everything working fine except brightness slider (wrong scale) and brightness change after wake from sleep.
Since I don't have Device (LCD) or similar section in my DSDT.aml, I couldn't manage to add BCL BCM BQC values. I don't know where to put them and which values to use.
Can anyone help me?

Attached is my DSDT and IOReg snapshot.



Thanks!

Edit: I've added RWEverything snapshots while changing brightness in Win7.

Made driver out of ivik's sources for ML10.8.3(SDK and so on)
In my case brightness was working before without  these modifications. But only with Fn+< and Fn+>
But now with this kext, Slider of brightness works
But I found a little bug. I see sun of brighness only with Fn+>.
Whereas with Fn+< brighness reduses but in this case I don't see the sun of brighness. And pointer of brigness stayed in the same place.

P.S. I use DSDT's midification which is suggested at first message of this topic.

Forgot to tell.
If pointer of brightness is moved from maximal position to minimum position straight away, brightness doesn't change.

And also brightness changes with latenesses through menu's slider.

With GenericBrighness I receive instantaneous reboot when I plug in HDMI-Cable to laptop.
ACPIBackLightDisplay does nothing with brightness.
And author of ACPIBacklightDisplay says that For some user of ATI card it isn't fitted for as a matter of the fact.
I just rechecked this.
Hence. A good driver of brigness just doesn't exist.
Removed all brightness drivers. My brighness is regulated fine by Fn-keys. And I even see sun bezel if slider was removed to minimum posirion and if to be heightening the brightness by combination of keys namely Fn+>.
