AMD Radeon HD 6650M / Graphics Enabler / DSDT / HDMI Audio / Acer Aspire 7750G - 2674G50Mnkk [Gradients Fixed]

Oh oops, I didnt really think of that... But whatever combination I use the effects never differ. It's like the LVDS value has nothing to do with the LVDS

 

Edit: Also, when patching, It usually finds 2 locations for the values, am I supposed to replace them both or only one? By now I have always replaced 2 of them

[Trucker MK]

One question: does the framebuffer "personality" that you modify really matter as long as the numbers for the output profiles are the same? If I have 2 personalities that have 3 outputs each and I set them to the same 3 16-byte values, are they then the same? Or do they affect something else along the line?

Not every Frambuffer will work. But you can edit more than one with the same Connector info, and boot with GE=Yes AtiConfig=FramebufferName, and see if it makes a difference.

Yes, one is for x32, the other for x64. 10.8.x only one, x64

It's getting quiet here, Merry Christmas and a Happy New Year To All.

I would like to share my Chameleon theme, maybe someone will like it. It comes with 3 backgrounds (OS X, Windows and my favorit Linux distro backtrack) merged in one. Take a look here

Download Default.zip

Rename the Default chameleon theme to Default_old and copy this one into Extra/Themes/

[Tauio111]

Merry christmas and happy new year to you too! You seem to be a fan of backtrack

I tried some design and made this, still havent found a way to get my LVDS working, it just doesnt work, anything I try it never differs. For some reason I think that I need DSDT modifications for it to work, got anything to recommend?

Hi, Tauio111. I think I have the same problem as you - black screen for LVDS. But I have slightly different graphics - ATI HD7670M.

I installed some kexts from the internet. The guy, who posted them, had different senseid then me and it worked for him. But I have senseid=07 and thus no LVDS.. With any senseid it's a black screen with a backlight, but when I patch with senseid=07 then it's black screen with no backlight. Tried many different senseid's and EDID already, but nothing works. VGA and HDMI work like a charm, with full acceleration.. LVDS is not working because of that stupied senseid=07.

Tried also EDID for a notebooks screen, but it makes things even worse - then VGA stops working. EDID worked for ATI5000, but seems it does not for ATI6000 anymore. I have no idea what else could we try. DSDT? I have no experience at all with that

[Tauio111]

I have the same senseid if i remember correctly. I have never gotten the backlight to work on the LVDS, ofcourse only if i pull out the VGA cable and then press the screen detection button, but doing this messes everything up quite badly.

@ freeuser 16

It's not just the SenseID that matters, if it doesn't work after changing it, try and play with Transmitter, Encoder, ATY,ControlFlags values. Read muchas thread for more info.

Has anyone already enabled 6 series card with senseid=07 with just changing Transmitter, Encoder, ATY,ControlFlags? Or are we doing this blindly believing that it might work?

Also maybe you could suggest some range of values for Transmitter, Encoder, ATY,ControlFlags to try?

[Tauio111]

Noone as far as I know, atleast with HD6000m series

Hi my name is Patrick I live in Canada and I speak French that why my English is so bad! I have a 7750G-6623 I-5 2430M 2.4ghz with switchable graphics between intel hd3000 and HD6650 1GB Vram 6gb Ram. I had install mountain 10.8.2 and tune my EDID to match my display, I pass almost 30 hours reading every where and still not able to make my hd6650 or intel300 to display other then HDMI. I had watch the video to dump my Vbios and attach to my post...Could someone help me to go further? I had change my boot file place the ati6000 for the 10.8.2 that I foud here, install chimera 1.11 boot with GraphicsEnabler=Yes AtiConfig=Ipomoea Still no luck. Thank you in advance. I don't have a dsdt yet I don't know much how to path a dsdt.

Hi, patane.

 

Probably the best and easiest solution for you would be to disable ATI Radeon card (dunno if it's possible) and use only HD3000 on Mac. I saw some threads about enabling it, but I can't really say anything more since I don't have integrated graphics at all (it's disabled in BIOS).

If you want to enable ATI Radeon, firstly decode your VBIOS with redsock_bios_decoder and radeon_bios_decode. You can find those scripts here on forum or in Google. Then binary patch of ATI6000Controller is needed according to gathered data from scripts.

[patane]

Hi i didn't try much with the hd3000 and i was hopping to find someone with exactely the same card that could tell me if it work in 10.8.2 and if they could share me their instruction to make my 6650 work as other.

Guys, who use Clover bootloader
Try to injecting EDID with clover, I have found that an editing DisplayProductID-717 causes wrong definition of LVDS. OS X shows it as an external display.
For this you must delete or return original DisplayProductID-717
And configure clover <key>CustomEDID</key> with your EDID
then
<key>InjectEDID</key>
<string>Yes</string>

That's it. This solves my problem with correct connectors and 16bit colors(gradients) on my ATI 5470m

You have the same VBIOS as i have, below is your vbios decoded with radeon_bios_decode. So, both options: GE=YES + patched ATI6000Controller.kext and DSDT patch + patched ATI6000Controller.kext should work for you. But, Your problem is with switchable graphics, if you can't find a way how to disable your HD3000 you wont be able to use the 6650M. I really can't help you here because i dont have any experience with switchable graphics nor the hardware to test it.

I need this kext.

I am now downloading the latest Chameleon source and I will look into it, if your SubsystemID 0513 is not included, i will compile a new Chameleon boot file with that SubsystemID, than you can try with patched ATI6000Controller.kext. You can download kexts in post #1, today a have updated most of the kexts and put them in one place for easyer downloads.

 

Here, try this boot file in combination with this kext 10.8.2_GE_ATI6000Controller.kext.zip , it should work Boot with GraphicsEnabler=Yes

Tauio111, and everyone else who have problems with LVDS on 6 series ATI graphics cards with senseid=07! I managed to enable my 7670M! Here is my post with an English translation: http://www.applelife...-11#post-339043

You can try it with 6650M as well, I think it will work

Many thanks for mmon for the help!

My clover goes black when using that plist file :/, should it theoretically work with 10.7? I also cant boot into OS X (it restarts during the boot up) when using Clover with UEFI

[freeuser16]

You should use original ATI6000Controller.kext and original DisplayProductID-717. Moreover, if you have different parameters (transmitter, encoder etc.) then me, you should also change the connectors patch in config.plist

oh, okay Ill make sure about those things

I dont have PEGP in DSDT, what do I do?

Edit: I have Device PEG0 which includes device GFX0, should I use this instead?

Edit2: My VBIOS doesnt fit there

[freeuser16]

Trucker MK, I'm using AppleHDA on 10.8.3. VoodooHDA works very bad for my ALC269. AppleHDA is much better, however sometimes built-in microphone stops working. After sleep it's working again till the next random crash. No idea how to fix it.. Everything else (Speakers + headphones with auto detect, external microphone port with auto detect) works very well

[acero]

hiTauio111,

how do you load clover with USB working?

i did try Clover and unable to use usb keyboard and mouse,unable to find EHC1 controller...

i use an Acer 7750g motherboard as a desktop computer ;;;
