The first screenshot is telling me that the framebuffer did not load. I use to get that screen when only AppleIntelHDGraphics.kext was loading. The second, have you tried the alternative framebuffer in my zip file?

 

What I want to know is if the framebuffer detects your display. For example in mine, it does. If it does detect your display, something is weird.

 

Ok GhostRaider, thanks for your help. I did some more tests on a vanilla 10.8.2 OSX installation. I tried both your FB and I get the same screen with the spinning wheel never stopping. I add a pic to this post. I was able to get to the desktop without any Intel HD kext loaded.

In a previous post I posted a pic about a distorted screen. I used the FB (not the alternate) in your .zip file with the DualLink FB from Verteks "fixed" ML FB. You think the FB was loaded in that test?

 

How can I know if the FB detects my display?

 

I think the problem might be the fact that my laptop monitor's EDID is not picked up by osx. Not even in Windows 7 nor in Linux Mint I was able to get the EDID. Only in windows I was getting it from the registry and not from the monitor itself.

Below you can see the output of the get-edid from Linux:

 

sudo get-edid | parse-edid

parse-edid: parse-edid version 2.0.0

get-edid: get-edid version 2.0.0

Could that be the reason why I cannot get the FB loaded?

OK so I forgot to mention one thing :worried_anim: . In your IGPU, you need to go to Device DD02. Before the line " Method (_ADR, 0, Serialized)", you will need to add the line " Name (_HID, EisaId ("LCD1234"))".

 

Can you confirm you installed the latest Generic Brightness kext?

 

I also noticed you already have two PNLF devices in your DSDT. You will probably need to remove the old one, its in a different place. Also try putting my OperationRegions before your line " OperationRegion (PNVS, SystemMemory, 0xDB79BDA4, 0x0100)".. let me know how it worked!

I have exact the same problem. Cant find the entry you pointed. Appreciate your help.

Hey calmesal. To find your graphics module, search for "Scope (_SB.PCI0.GFX0)". There you will find Device DD02. You need to name it LCD1234 as per my instructions. Put my OperationRegions before the first occurence of your "Scope (_SB)" and then find your Device (PNLF) {....}, delete it and replace with mine. Let me know if it worked. (If you can't compile, try replacing whenever my code says "PCI0.GFX0" try and change that to "_SB.PCI0.GFX0")

Hi mnorthern

i have a g62 like you. I tried your patch with GenericBrightness.kext and it didn't work. I patched my dsdt correctly and the kexts seems to find the device DD02 with LCD1234 as name, but the brightness doesn't work (there's no slider too).

Little update: i can confirm that Natit is not mandatory to get to the desktop. I deleted it (it changes also some things on the ATi card!).

 

Last thing: my notebook is overheating on OS X! (not on Windows!). Any solution?

 

 

The real last thing: update 10.8.3 released, please verteks patch the new files (or release a patcher).

Hi giofrida, can I have a look at your dsdt? Also, would you be able to download RW-Everything on Windows, then go into PCI window, select your Intel Graphics from the drop down, and send me a screenshot of what it shows? Also, when you go into Displays preference pane, what does it look like?

 

Also, I have edited my original instructions on the previous page for more clarity.

 

EDIT:

$h!t, I made a mistake :D Too many KEXTs loaded on my system and it looks like a mess. Do not install Generic Brightness, if you have it delete it. My DSDT patches will work if you install the following driver made by hotKoffy from our forum (http://www.insanelym...cklight-driver/) but I made slight changes to the plist, so download the one I attached and give it a go.

I'll try it, thanks.

 

@verteks: this is the 10.8.3 framebuffer, please patch it.

Let me know how it works. Also, my hackbook overheats when watching a HD movie, I wonder how to solve this. Also wonder how to enable HDMI out

Correct dsdt and maybe you can edit your smbios.plist to reduce max cpu-multiplier.

 

I have 43-46C on the low state and 56 on the max state.

Could you elaborate on correct dsdt? I have applied all the standard patches to mine. Please post some links thanks

Hey calmesal. To find your graphics module, search for "Scope (_SB.PCI0.GFX0)". There you will find Device DD02. You need to name it LCD1234 as per my instructions. Put my OperationRegions before the first occurence of your "Scope (_SB)" and then find your Device (PNLF) {....}, delete it and replace with mine. Let me know if it worked.

Hi again!

The first and second part was no problem, but the PNLF part is no go. If I delete and copy your code I get compilation error. And I dont anderstand what you mean by(If you can't compile, try replacing whenever my code says "PCI0.GFX0" try and change that to "_SB.PCI0.GFX0")

I will be thankful if you could do this on my DSDT.

 

Thanks

Hello, now brightness control is enabled in my laptop, the only issue is "range" with 100% (slider) backlight is about 85-90% and 0% (slider) screen is too dark and F1(-)-F2(+) keys working for backlight but only once then don't change brightness.

 

Thanks mnorthern

thanks for the report, i will try to fix the 100% to a higher setting, and fix the keys

 

when you set it to 0% do you get a completely black screen? i may need to fix this to a higher setting

@mnorthern, can I get BAR0/BAR1 using DarwinDump?

 

I've never used DarwinDump unfortunately... but I edited my original post, and provided instructions how to use Windows and RW-everything.. its the easiest way!

I'll try to patch your DSDT tonight and send it to you for testing !

When I set it to 0% screen isn't completely black (is too dark, more dark than 0% when I use windows).

i'm using patched fb and ga/gldriver/vadriver from 10.8.3. i'm not using aihdg.kext cause for me (i5 450m - intel hd 1st + nvidia g310m) it didn't work neither with 10.8.2

You mean that you dont use the AppleIntelHDGraphic.kext?

If yes, what version? Original or MLDP2.
