Well, I've searched high and low, and am getting closer to a solution, but not quite there yet...

 

I managed to get brightness control with the menulet. However, I have no brightness slider in display preferences at all. I do have the PNLF device added to my DSDT. I have also tried injecting info for my card (NVidia Geforce 9300M GS), but every time I do, the correct drivers are not loaded, but I get regular 1024x768 VESA resolution at logon with no QE/CI or brightness control.

 

Any ideas from anyone? My DSDT is attached.

Hi,

 

the second method don't work for me (Lenovo G570, 10.7.1). After install GenericBrightness.kext and DSDT modification dmesg show:

Acpi brightness levels:11, lowest brightness:10, highest brightness:100 
GenericBrightness: Kernel Control Registered

No slider in SystemPreferences and Fn+Up or Fn+Down don't work.

 

My DSDT:

DSDT_Lenovo_G570.aml.zip

 

Thanks!

You don't add PNLF device to the \_SB , so you can't see slider in the SystemPreferences--Display. I add that Device for you, try it.dsdt.aml.zip

Hi Zprood!

 

Thanks for your help. Now, I can adjust screen brightness in SystemPreferences-Display section, but the Fn+Up, Fn+Down or Brightness Menulet doesn't work. In terminal brightness get result is 0.

 

Now I use ApplePS2Controller.kext because VoodooPS2Controller.kext doesn't work. If I use the second one the FN key maybe work?

I see you have a Lenovo laptop and me too, the problem is we can't get Fn+up/down scan code with debug version VoodooPS2keyboard, it is not a static value, so if your laptop get the driver work, you can use the "Pause" and "Fn+Delete" key to adjust the brightness. In my case, i can use them all, even Fn+Up/Down, I don't why you can't get Fn+up/down work, maybe you can take a look in your dsdt, also put it reboot see whether it change or not.

Hi Zprood,

 

thanks your tip! In my laptop the Fn+ScrLk and Fn+Pause work.

BTW if you have a Lenovo laptop can you help me with the sleep, maybe? I put SleepEnabler.kext to E/E but after system go sleep immediately reboot the laptop. Sorry for the offtopic.

 

Thanks again!

I have one too, but it is too old, i wanna to help but can't do that. Cause I just know my hardware and how to get it work. BTW you can search the forum by using the your laptop's model, chip etc. Sleep problem is related USB high speed bus, such as EHC1, EHC2. Hope you can get good luck.

Hi,

that my situation: I have three netbook two Samsung NC10-N130 and one Acer Aspire One A110L, all with 10.6.8 same setup. I patch DSDT same way (add PNLF) but The Samsung have _BCM _BCL _BQC in DSDT Aspire no.

The result is that Samsung have Brightness from slider and fn Key (F12/ins) (also sun icon) working.

Aspire have slider that move fn key (F12/ins) (also sun icon) The number change also in ioreg (the number are the same 0x400/max-0x0/Min, and change the same way in samsung and Aspire ioreg: three press down give the same value in ioreg 0x340) but brightness not changing. I can use fn arrow up/down but with no sun icon as without DSDT to dim (no sun icon also in XP and Ubuntu).

The brightness is controlled directly from BIOS and the step are written in BIOS in fact the minimum value change in different BIOS version (I read it somewhere)

The brightness is controlled from EC. I can see in rw everything one number (EC 66/62 reg 51 (81)) change from 00 to 09 during fn up/down key pressure, and if I write on it the brightness change.

 

So the question is: can I add _BCL _BCM _BQC to aspire DSDT? Can I discover the name of register for store Brightness and if yes how can I find it? Maybe BLVL?

 

Or there is no hope to use vanilla brightness on Aspire One?

 

PS: I have look inside DSDT from a MacBook (Gma3100) and from a MacBookPro (8600M) and there are no _BCL, _BCM, _BQC on both so I hope is possible also on Acer, but my knowledge is very poor and I'm stuck here.

Hello,

 

I have managed to get the slider active under display but the brightness is erratic and non linear! I tried to follow the instructions from here:

 

http://www.insanelymac.com/forum/index.php...p;#entry1747344 but when I try to compile the dsdt file with the changes its produces errors.

 

I have a 6510b with X3100 graphics.

 

Any help would be great!

Fist of all thanks for this topic, topic starter.

But I can't set brightness of my Toshiba A-100 internal LCD with topic starter instructions.

A bit later on Tony's site I found something and I have it mixed whit topic starter instructions and made the brightness work besides some inconveniences (my VGA display stops autodedect) .

SO what I've done.

1. Added to Device (PNLF) to Device (PCI0)=> Device (PEGP)=> Device (VGA)=> Device (LCD) where were _BCL, _BCM, _BQC methods (these methods I include to Device (PNLF))

					Device (PNLF)
					{
						Name (_HID, EisaId ("APP0002"))
						Name (_CID, "backlight")
						Name (_UID, 0x0A)
						Name (_STA, 0x0B)
						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)
						}
					}

2. installed GenericBrightness.kext

After that I get brightness , but alway on 100% of brightness.

3. Added to org.chameleon.Boot.plist next keys - MacBookPro6,1 properties and system type as a notebook :

<key>device-properties</key>
<string>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</string>
<key>system-type</key>
<string>2</string>

4. Change smbios.plist to MacBookPro6,1.

 

After that I got working brightness but my VGA display stops autodedect. How can I fix my VGA problem and delete MacBookPro6,1 key from org.chameleon.Boot.plist ?

Thanks a lot.

^^^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

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?
