<br />Has anyone ever gotten DVI or HDMI working with the GMA950? It seems to me that OS X can't see a display on it, so only sends out the blue screen...<br /><br />Patrick<br />
<br /><br /><br />

 

That works on my desktop with Leopard (with patched AppleIntelFramebuffer.kext and some not annoying artifacts). The motherboard is an ASRock 945G-DVI. No luck with 10.6 yet - maybe because it doesn't support AHCI.

Hi

I've read the whole thread and, since english is not my mother tongue, I think I don't understand the entire thing about the fix.

I mean, I have an Intel D945GCCR motherboard with an Intel Celeron D @2.53 GHz (Socket 775) on it. I installed iATKOS v7 and it runs pretty well, Wifi (Zydas 1211 USB adaptor), Sound (VoodooHDA for the built-in Realtek ALC883 sound card makes Line-In and front panel works OTB), etc. But Im getting some artifacts when I hover text-boxes, just how some of the people is describing here.

Well, my only issue with my setup, as you may guess, is the infamous GMA950, which is giving me some artifacts when I hover text boxes. I was trying with the fixes posted here, but everything I get is an unbooteable system and 10 minutes lost booting from de CD-ROM and reinstalling the provided drivers (and the artifacts with them).

So, what da !(#&$)# I've to do to fix it? Please help me, I don't want to go back to Windows :P

10.6.2 includes 64bit driver for GMA950 and newer chips. The drivers are buggy - so I personally don't recommend using them till Apple updates them in future updates.

 

In my case, the monitor doesn't wake up after sleep. It works perfectly in 32bit mode.

Why there is no Device(PCI0) in my dsdt.dsl?

 

 

 

Beta testers wanted:

 

I've found an alternative universal drop off location for the 1st part of the code for all those who couldn't find Scope (_SI)

 

Here is the updated instructions with the new drop off location and the new code which greatly improves compatibility with 10.5.7 and probably future updates especially the pesky Snow Leopard.

 

Your feedback is greatly appreciated. I'll update the fist post once I sure the instructions are free of mistakes and the new code works.

Same here DR.Hurt, monitor doesn't wake up after sleep in 64-bit, did u find any solution yet or any hope for a solution or do we need to wait for apple to update the kexts.

 

Another thing I had a strange problem with the combination of SL & GMA950 hack in dsdt. I modified my dsdt with Evosx86 'DSDTSE' Patcher v1.3. I always used to get 'ACPI' kernel panics at boot whenever I try to boot SL in 64-bit mode with 'GMA950' hack in dsdt, if i remove that no kernel panics. This problem has haunted me for the last three months. At last I found a solution thanks one of the moderator of EvOsx86 forum, who suggested me to change the lines "Storage (Package(0x1A)" in the 'GMA950' hack to "Storage (Package()", voila that has solved my problem.

NOTE: If u use latest version of DSDTSE(1.42 as of now), u will get a remark about this specific line. If u change the line as i explained above the remark goes away so as the 'ACPI' kernel panics(if u have any). My board is Intel 945GCNL with 945GCR chipset, if u have same board & same chipset and facing the same problem, this is the solution.

I have a GMA950 (2772) and Snow Leopard 10.6.2 (64-bit).

 

With Dr. Hurt's DSDT patch everything boots up fine but I get a blank gray screen, no logo, no wheel, nothing. What could this mean?

 

If I don't use the DSDT patch 10.6.2 boots up fine and detects my GMA 950 but QL/QE and 3D is off and the resolution is stuck at a maximum of 1280x1024.

 

Can someone confirm this DSDT fix works for 10.6.2 (64-bit) with GMA950 (2772)? Or could someone please give me a clue as to what the blank gray screen means?

Patched and compiled my own DSDT file for the Intel GMA 950. Got all resolutions working but no hardware acceleration. Videos lag in full screen mode, and front row runs but I can't see anything. This is for a Dell GX520, using all stock kexts, any thoughts? I'm attaching my DSDT file.

ok, i solved the problem by using the iatkos install disk, using the terminal to delete the DSDT file

 

then i tried the DSDT file from V3 and V4, both didn't work, they both go as far as the grey apple loading screen without the loading icon showing up and hang there.

 

now the problem is, i tried the v3 v4 and the patch, they dont work, what else i can try??

 

at the moment, using the v3 ktext files, it has QE support, but the resolution is limited to 1024x768, can't change to any other.

 

please help me. thank you

I know just how you feel... I've been struggling with my Aopen Mini PC MP945-D now for a two weeks with this issue. I use 10.5.8 retail, and get QE with all original stock drivers. However, the only display option is 1024x768 no matter what I do. Originally I blamed it on the composite line out to the tv, but now I have it hooked up with a DVI / HDMI cable- still no change. The EDID isn't being picked up. The TV isn't the problem (a brand new Sony HDTV), as it works perfect on my X3100 laptop. I've tried my trick of including the Sony's EDID in the default display override; the override is used (display is now named) but the EDID isn't! No new resolutions.

 

I'm now frustrated enough to consider installing Linux or Win7! SwitchResX made no difference (and is now expired)... various hacked drivers either do nothing, or make only a blue screen show on bootup... I've edited the DSDT with various 950 "fixes" with no change.... Starting to believe that this machine lacks the ability to transfer EDID data, as weird as that sounds. I'd be happy hard coding it to something widescreen.

Hi,

hi, thanks for the help, i solved my problem by reinstalling the iActkos v7, and choose ONLY GMA950 Desktop (previously i ticked all Laptop, Desktop and Rare)

 

now it has qe, can change resolution.

 

but there's still a problem, it provides wrong resolution of my monitor, my monitor is a 19" 16:10 monitor, and the resolution for choose are all 4:3, something like 1024x768, 1280x1024...

 

i tried to connect to another monitor which is a 23" Full HD monitor16:9, it gives me higher resolution, but the options are still 4:3 format.

 

any tips??

 

thank you

Regarding the DVI/HDMI issue many people seem to be having, it looks to me like the GMA950 driver only supports a single graphics pipe from the chipset which defaults to the built-in VGA connector on the motherboard. The Mac Mini version which had this chipset only had a single DVI connector, so there was no reason to support both graphics pipes.

 

What I'm thinking needs to be done is to add a command into the DSDT to tell it to use the other pipe (which connects to the SDVO -> DVI on my motherboard at least). I've found this from another posting:

 

"AAPL01,Pipe",

Buffer (0x04)

{

0x01, 0x00, 0x00, 0x00

},

This would be inserted into the second section of modified code (after built_in).

 

I'm going to try it when I get home tonight. Any comments? Am I barking up the wrong tree?
