UPDATED 20.12. GenericBrightness.kext

ivik · December 9, 2010

Nice!! Could you check if VoodooPS2 is corectly mapped?

This is info that i have found and mapped those keys: http://cgit.freedesktop.org/~dkukawka/hal-...keymap-dell.fdi

this is what i currently have in mine
 VoodooPS2Keyboard.cpp
	 0x00,0xe0,0x06, //90 Main Brightness Up
	 0x00,0xe0,0x05, //91 Main Brightness Down
.....
	 NX_KEYTYPE_BRIGHTNESS_UP,	   0x90,		// brightness up
	 NX_KEYTYPE_BRIGHTNESS_DOWN,	 0x91		// brightness down
ApplePS2ToADBMap.h
 0x91,   // e0 05   fn+down to brightness down
 0x90,   // e0 06   fn+up to brightness up
I assume that was correct to do or am i missing something

what was stated in the code is the default voodoo mapping it has from when i was getting the scancodes

This is only modification to VoodooPS2Keyboard.cpp:

        // special key definition
       0x0d, // number of special keys
       // ( NX_KEYTYPE,        Virtual ADB code )
       NX_KEYTYPE_CAPS_LOCK,   0x39,
       NX_KEYTYPE_HELP,        0x72,
       NX_POWER_KEY,           0x7f,
       NX_KEYTYPE_MUTE,        0x4a,
       NX_KEYTYPE_SOUND_UP,    0x48,
       NX_KEYTYPE_SOUND_DOWN,  0x49,
       // remove arrow keys as special keys. They are generating double up/down scroll events
       // in both carbon and coco apps.
       //NX_UP_ARROW_KEY,        0x7e,       // ADB is 3e raw, 7e virtual (KMAP)
       //NX_DOWN_ARROW_KEY,      0x7d,       // ADB is 0x3d raw, 7d virtual
       NX_KEYTYPE_NUM_LOCK,    0x47,       // ADB combines with CLEAR key for numlock
       NX_KEYTYPE_VIDMIRROR,   0x70,
       NX_KEYTYPE_PLAY,        0x34,
       NX_KEYTYPE_NEXT,        0x42,       // if this event repeated, act as NX_KEYTYPE_FAST
       NX_KEYTYPE_PREVIOUS,    0x4d,        // if this event repeated, act as NX_KEYTYPE_REWIND
	NX_KEYTYPE_BRIGHTNESS_UP, 0x90,
	NX_KEYTYPE_BRIGHTNESS_DOWN,	0x91

and ApplePS2ToADB:

    DEADKEY,// e0 04 
   0x91,// e0 05 dell brdown
   0x90,// e0 06 dell brup
   DEADKEY,// e0 07

it ried what you just recommended

and removed my

0x00,0xe0,0x06, //90 Main Brightness Up

0x00,0xe0,0x05, //91 Main Brightness Down

lines from the file and still only getting dells brightness adjustment on here

maybe i have an issue with my dsdt which i dont think i do but here it is just in case

	}

really confused as to why remapping the keys wont override dells default brightness adjustment which btw works independently of the slider in displays

ok so the new files almost fixed my issues with up and down keys
if i reboot i can up the brightness but if i go down its like it locks in and goes to 0

I saw that at 15.09.2010

My experiment with brightness keys has a bug so I exclude it in the version.

It is not only key remapping needed. I don't know. I decided to use Apple's keys Fn+Scroll/Pause and don't remap brightness in PS2 driver.

ok so its not just me experiencing this must be another dell issue like black screen on boot

ill just use the defaults than also

ivik · December 9, 2010

Maybe dell keys don't generate up event?

weizh126 · December 10, 2010

@ivik, could you please upload the source? I mean I want to modify the source and change the hotkeys. I just want to use Fn+PgUp/PgDn instead of ScrLK&Pause.

Fn+PgUp mapping to brightness down

ApplePS2Keyboard: PS/2 scancode 0xe0
ApplePS2Keyboard: PS/2 scancode 0x47
ApplePS2Keyboard: ADB key code 0x73 down
ApplePS2Keyboard: PS/2 scancode 0xe0
ApplePS2Keyboard: PS/2 scancode 0xc7
ApplePS2Keyboard: ADB key code 0x73 up

Fn+PgDn mapping to brightness up

ApplePS2Keyboard: PS/2 scancode 0xe0
ApplePS2Keyboard: PS/2 scancode 0x4f
ApplePS2Keyboard: ADB key code 0x77 down
ApplePS2Keyboard: PS/2 scancode 0xe0
ApplePS2Keyboard: PS/2 scancode 0xcf
ApplePS2Keyboard: ADB key code 0x77 up

After mapping is done, I won't use Pause and ScrLK at all, so how can I block them, I mean nothing will happen when pressed.

And report a bug. When I use touchpad(Synaptics ), I find something very strange.

1) It needs double clicks on the touchpad to instead of one click, for example, when I click on the close button to close an application, it should be one click, but now I have to click twice.

2)When clicking (not moving ) touchpad in an application, sometimes I cannot left click the usb mouse and right&middle click are ok , and the keyboard is OK, so I have to use ALT+Q to close the application, then everything goes right again.

Thanks

Edit:

I am sorry, ivik. The strange things are caused by the prepane of voodoops2controller.kext. It's my own fault. Using this prepane, everything goes well, though the function of this prepane is very limited.Trackpad.prefPane.zip

@Scorpy22 - Thank you so much for your work on Nvidia. My Vostro 3500 now behaving wonderfully, complete with auto-dim on battery. Nice one! <img src="style_emoticons/default/smile.gif" style="vertical-align:middle" emoid="" border="0" alt="smile.gif" /> @Ivik, thanks too for all the work you have done on this thread that kick started a lot of thought on brightness.

hello MiniHack

could u upload your worked dsdt?my laptop's graphics card is gt240m , now the situation is that max and min are aways 0 in ioreg as you case. and how do you driver your Nvidia card?dsdt or gfx string ? what about 'PNLF' ,is it necessary? please upload them together.

thx advance!

ivik · December 10, 2010

@weizh126

You wanna map HOME and END to brightness?

weizh126 · December 10, 2010

@ivik

Yes, it is much more convenient for me.

ivik · December 10, 2010

These keys are already mapped. You could use spark for that.

weizh126 · December 10, 2010

Oh yes, I forget that, I'll try it now. : )

Edit:

The brightness changed, but the SUN did not show...

Edit2:

Sorry, I forget checking the "display notification icon". This time the SUN appears.

sw170 · December 11, 2010

SUCCESS !!!
...

Hi Scorpy22, thanks a ton for sharing, I have now brightness&SUN logo with Efi string + my card info via DSDT and Ivik's kext, do you or any of you guys reading this know how I can convert these kind of values and inject them into DSDT ?:

		<key>@0,EDID</key>
	<data>AP///////wBMo0UyAAAAAAASAQCAIhN4Cof1lFdPjCcnUFQAAAABAQEBAQEBAQEBAQEBAQEBQRxWoFAAFjAwICUAWMIQAAAZAAAADwAAAAAAAAAAACOHAmQBAAAA/gBTQU1TVU5HCiAgICAgAAAA/gBMVE4xNTZBVDAyMDAwAHw=</data>

,

		<key>@0,pwm-info</key>
	<data>AhgAZJBZAgAIUgAApRwAAAAEAAABAAAA</data>

I tried to look in forum but failed basically.

Again Huge thanks to you Ivik for all your brilliant work, I must say I got really attached to your brightness terminal utility, especially brightness set command, now with PNLF method this doesn't work, is there any OSX equivalent for that? (Tried to find it as well but failed here too) if not - any chance you could adapt it to PNLF method ?

Regards

s

EDIT:

no idea how to change this over stretched code, sorry for that

weizh126 · December 11, 2010

@swavek

Hi swavek, maybe you can try this method, I managed to inject the pmw-info.

so the @0,pmw-info is

<01140064 a8610000 08520000 01000000 00040000>

then I inject the following codes into DSDT

 "@0,pwm-info", 
							Buffer (0x14)
							{
								/* 0000 */	0x01, 0x14, 0x00, 0x64, 0xA8, 0x61, 0x00, 0x00, 
								/* 0008 */	0x08, 0x52, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 
								/* 0010 */	0x00, 0x04, 0x00, 0x00
							},

I do not inject @0,EDID, because after injecting @0,pwm-info, everything seems OK.

Hi weizh126,

                   }

and Scorpy's Efi string removed from apple.boot.plist I'm loosing brightness controlled via system+SUN logo, maybe you can spot in my code something that is missing from Scorpy's plist which you also got in you DSDT? If not I shall add piece by piece and trace missing part, parts

thanks for posting your guide how to convert info from plists, really appreciate that

"@0,backlight-control", 
							Buffer (0x04)
							{
								0x01, 0x00, 0x00, 0x00
							}, 

							"@0,display-cfg", 
							Buffer (0x04)
							{
								0x03, 0x01, 0x00, 0x00
							},

I do not test one by one, I inject the three parts, @0,backlight-control,@0,display-cfg and @0,pwm-info at fist time, then it works very well. Maybe it will help you : )

Hey Ivik,

Heh,

rather more interested in what way or what program you used to convert those numbers, but appreciate this ready meal too

thanks mate

Maybe it is Base64, not hex.

Here is the explanation

Hi swavek, here is my GFX DSDT part,

...

Great !

going to do some testing now, will post results ...

cheers

Here is the explanation

thanks buddy,
will study that next free eve, in the meantime two things:

those two parts of code made my backlight back without Efi string, thanks again for your help weizh126 !

"@0,backlight-control",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00
},

"@0,pwm-info",
Buffer (0x14)
{
/* 0000 */ 0x01, 0x14, 0x00, 0x64, 0xA8, 0x61, 0x00, 0x00,
/* 0008 */ 0x08, 0x52, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00,
/* 0010 */ 0x00, 0x04, 0x00, 0x00
},

second: backlight after every reboot switches itself to max level, is that my machine only ?

Regards

@swavek

Hi swavek, congratulations! The brightness is quite normal here on my laptop, maybe you can try this genericbrightness

And also you can read Post #266. I modified the ivik's source and changed the timeout to 1 second, it works perfectly here.

Edit:

Yes, swavek. You are right, @0,backlight-control and @0,pwm-info are the necessary parts to make the brightness right. @0,display-cfg is not necessary. Thanks, man

Edit2:

Oh sorry,swavek, I mean the brightness is also normal after reboot and the brightness value stays the same as the last shut down, no strange things happen.

ugh, actually I wanted to say that my brightness works fine here - slider works, SUN logo too, its just after reboot I have to decrease brightness straight away bacause it sets itself to max

ehh will try to sort that out tomorrow..

bed now

seya!

EDIT:

ps. what you mean you changed timeout to 1sec ?

nevermind, yeah post 266.

janek202 · December 11, 2010

I menaged to get almost fully working native brightness control with DSDT patch. (with help of Bungo)
I can change it using keys (sun logo appears) and I can change it smoothly using slider in system preferences.
I have one problem, when I set it to minimum the backlight is being turned off, and I can't turn it on, only reboot helps.
I found source of that issue. In IOreg in backlight section I have:
max: 0x400
min: 0x0
I think the problem is value 0x0 in minimum and it disables the backlight. It should be something like 0x8. If anyone have an idea how to fix it I would be thankful.

@swavek

Could you please read post 50 and 193?

It looks like brightness register is BAR0 + 61c084 for nvidia. Problem is that you have this register set to max, but your laptop controls brightness with EC.

Try moving slider, and read that memory. If this values changes, then we could easy sync boot brightness to one from EC.
