Hello to all great hackers.
I see a lot of knowledge in ACPI programming here.

I would like to ask for some help because im not so good at this.

I have an iMac from late 2009 with i5, 8Gb ram, ssd and now also GTX 765M, old 4850 died as they usualy do in imacs.
The card works oob but without bootscreen and brightness regulation, same as many imacs with gpu changed to non apple.
I know bootscreen needs apple efi, i will get to vbios hacking sometime later, for now it would be great to get brightness controls back and this is why im here.

I think the problem is only in display detection as it looks like its not detected as built-in (AppleDisplay instead of AppleBuiltinDisplay in ioreg)

I installed clover and tried some patches, also compared DSDT before and after new card but my knowledge ends here.
Only difference i got is when i changed connector-type and properties in DSDT GFX0 device, black screen with mouse pointer and backlight working. (blind typing to get it back:))
Seems like all usual patches are already present because its a real mac... well now its a frankentosh :)
The problem is also that there is no bootscreen and clover options on boot, so if something goes wrong im stuck, also no windows installed yet.
I tried some kexts in CLOVER/kexts/other because that can be disabled on blind on bootscreen.

I would be very happy if someone could take a look and give some suggestions to try.
Thanks.

I found differences in ioreg under PNLF

How do i insert options from right ioreg window to my DSDT?
 
I started adding options to my patched DSDT that are present in imac with original card and missing in mine, and discovered why i got black screen with mouse visible and backlight.
I must have all 4 connectors inside @0..3, if i put only @3 (where my display is connected) i get black screen.
This is currently in my DSDT under GFX0:
Code:

                        }
No more black screen and dither is enabled which is nice, all options are visible in ioreg and so valid.

If i add
Code:
"@3,built-in",
Buffer (Zero) {}
i still get black screen (no mouse and no backlight) and with remote display i see that display is not connected.

What is AGPM gpu-control? This is usualy under @0 but if i add "built-in" option to @3, AGPM connects to @3 and no display...
I would really appreciate little help.

Hi CoolBits, will likely join you sometime soon with the GTX765M. Just waiting for my 6970 to fail. There are a number of threads that are relevant for backlighting fixes on hackintosh laptops -- search for "backlight dsdt nvidia" etc. May even be a GTX765 fix out there!
 
Hi. Yes i read all relevant threads and it seems easy to do it on a hack but not so much on a real mac because all usual hacks are already present here.
But i got it to recognize display as internal and got brightness controls back but the brightness doesnt actualy change yet.

Hello, CoolBits! Any news on your research?
 
No nothing since last post, imac works but brightness still on ful blast.
This also generates more heat so i need to find a solution, did not have much time to play with this.
 
Hi CoolBits2,

Do you mind sharing your DSDT please?
I also bought a 765M GPU for my 27" iMac.

Willing to try your hack and clover.
Thanks in advance!
 
Yes no problem.
In clover i changed board-id under smbios (on picture) and under Rt Variables i changed BooterConfig (0x0028) and CsrActiveConfig (0x0067) to disable system protection.

In DSDT i only modified under Device (GFX0) connector-types, display-connect-flags, hotplug, etc...
Probably not all is needed but experimenting.

Code:
