Leopard installed, but I have GMA950 issues

[zoomie]

I've successfully installed Leopard 9a581 GM with BrazilMac's patch on my Gigabyte GA-945GCMX-S2 mobo. Everything was recognized and supported by the installer right out of the box. I'm really pleased with Leopard and love TimeMachine. But there is one minor annoyance that I have. I'm getting screen/mouse trailing artifacts. The artifacts are minor and doesn't really affect the overall usability of my system...its just a minor annoyance. I'm using the mobo's built-in GMA950 video.

 

Does anyone else have similar issues?

 

Does anyone have any possible solutions?

 

Thanks,

Zoomie

In case anyone is interested, I fixed my screen artifacts issue by installing an older version of the GMA950 driver. I extracted the gma950.pkg file from the Kalyway 9a527 Leopard installer DVD. I had tested the kalyway build a few weeks ago and never had a video problem with that build, so on a whim, I installed that older version of the driver onto my new ToH Leopard build. I noticed an immediate improvement. I haven't had a screen artifact since installing the older driver a half hour ago. So far so good!

[MikeBee]

Sounds great. Can you by any chance share this .pkg file with the rest of us? It would be much quicker than downloading the Kalyway beta install DVD.

 

Thanks!

 

Is this the same install file from previous releases? I have an installer from my JaS 10.4.8 DVD.

[greatneo]

yeah plz share the gma950.pkg

thx in advance

[zoomie]

Well it seem that using the older drivers was just a temporary fix. When I rebooted, the screen artifacts returned. I guess we'll just have to wait until a newer driver is released.

 

sorry folks

ya, I have the same issue with firefox 2 and with photoshop cs3. curiously with firefox 3 alpha there isn't such a problem. I reckon that with the firefox 3 most of the extensions I have do not work and those r the reason i prefer it to safari. But could it be that it is one them causing the artifacts??

Well, its definitely the GMA950 driver that is at fault. I get some minor screen artifacts without Firefox running. However, Firefox does seem to make the screen artifacts worse.

[brlock]

i am aware that all comes down to the gma950 drivers, but in my system i have no artifacts if I only have apple software open. I just think it is curious that it does not happen if I use firefox3. Firefox2 must require something from the drivers that firefox does not...

 

 

And I may also add that these artifact are only created when the mouse pointer changes shape (ex. from the arrow to the hand) is it this with all of you?

Yes, I get that. But I also get a black square that appears on my desktop, just below the Apple logo on my menu bar every time I log in to my hackintosh...it disappears after a few moments though. I also get random squares, away from the mouse pointer, that appear when I use firefox, thunderbird, and itunes. But the random squares aren't as frequent as the mouse pointer glitches when using firefox.

Working fine here.

I wish we could merge threads.

 

As you know zoomie, I have the same problem. I have narrowed it down to the "AppleIntelIntegratedFrameBuffer.kext".

 

And now I will explain how I determent that. When you install Leopard and run the PostPatch it creates a backup of your framebuffer and names it "AppleItelIntegratedFramebuffer.kext.post", and replaces the original with a 10.4 version. After lots of trial and errors replacing different files with previous versions I came to the framebuffer.

 

If you change the .kext.post that the Patch makes back to just .kext and delete the 10.4 version, the artifacting goes away, but I only get one screen resolution(1024x768) but I have no artifacting/tearing/glitching. And I DO have QE/CI.

 

I compared the two framebuffers, the original Leopard AppleIntelIntegratedFrameBuffer.kext is 132kb, while the Tiger previous framebuffers are 192kb. Why the difference?

 

I also looked in the package contents and all .plist looks good and pretty much the same EXCEPT the main framebuffer file, but I havent figured out how to open that and see what is inside.

:censored2:

well the bug apeers when the mouse pointer changes shape i got a Dell 6400 and mouse works fine

but under leopard (flat image ) but i got the screen bug 2.

when i plug the drive in to my big tower with the ati X1900 its all fine.

tryed a few things kaleway drivers gave e a headage when you in stall then yes it works but, you lose CI/QE compatibilaty. i alsy tryed exrtrating the new drivers from the update for the imacs. but that just gave my laptop a black screen ..... think the resolution was way off i tryed setting the resolution diferent in the boot list but that does not work think we are :censored2:

Anyone got their GMA950 to wake up from sleep?

I get this as my puter wakes up, ToH install with framebuffer kext from brazilmac dl.

 

 

Abit LG-95Z

[Gooly]

gr8 to hear this. I have GMA 900 i will try the same.

[abcsoy]

OK so as far as I can tell,

 

GMA950---FrameBuffer---Result

tiger ... tiger ... all rez and CI/QE works, but mouse glitch

tiger ... leo ... All Rez, CI/QE doesnt work, and some report mouse glitch some dont

Leo ... tiger ... Kernel Panic

leo ... leo ... only 1024x768, CI/QE work, no mouse glitch

 

That just about sums it up, so pick your poison folks.

 

ps sorry for the formatting not sure how to make a decent table in here

[TheTimster]

for me, all the graphics issues i had were solved when i allowed leo to use its built-in kext. apparenty gma950 has out of box support in leo now. just skip installing separate 950 drivers when you install osx86, and you should be fine.for me, all the graphics issues i had were solved when i allowed leo to use its built-in kext. apparenty gma950 has out of box support in leo now. just skip installing separate 950 drivers when you install osx86, and you should be fine.

TheTimster, on the BrizalMac Leopard install there is no option to install gma950 under the customize tab, there for leads me to believe we are already using the built in original apple leopard gma950 drivers, the only thing that was changed/replaced was the framebuffer to the one from tiger. We cant get the original Leopard framebuffer to work without only getting one resolution to choose from, all though I am using this configuration right now and added my real resolution to the com.apple.plist, it didnt set it to that resolution but it did give me 1280x1024, witch is better then 1024x768.

[JamesD]

any update on this issue please? i think it's a VERY common issue for most leopard osx86 users who managed to set his/her resolution to higher than 1024*768

10.5.1 with GMA950 works fine for me with no screen artifacts. 10.5.0 had artifacts, but it also had different screen resolutions listed in System Preferences. Now with 10.5.1 it seems limited to 1024x768, but can be overridden in Boot.plist. However, X11 is not working at all. I've tried going back to Tiger X11, going forward to the development releases available through http://www.x.org/wiki/XDarwin, but there seems to be some code in the Xquartz miInitializeColormap X server that is too trusting of values returned to it, because I'm seeing the following

Hi guys,

I got fix my mouse pointer trailing issue. I use Natit kext for GMA950 & vanilla AppleIntelIntegratedFramebuffer.kext (10.5.1). My spec is at my signature.

can you post the files here so we can try them

I've managed to finally get my gma950 adapter working great on my laptop; no artifacts, full acceleration, full resolution abilities, and sleep/wake work great. I used GFX strings to recognize my graphics adapter instead of using hacked drivers. I get much better performance and of course no artifacts doing it this way.

 

By the way, I used the OSX86Tools to install the graphics strings.

 

If you need more info, just let me know...

On my laptop, I installed a vanilla version of 10.5.5 leopard. When using the stock gma950 kexts, my laptop boots up to a blue screen on my internal display. However, when you plug in an external monitor, everything displays on it just fine. I then used OSX86 tools utility by pcwiz to install GFX strings in my com.apple.boot.plist file. It's pretty self explanatory, just click on add EFI strings/boot flags, and then click the graphics part. It walks you through it all, its pretty intuitive.

 

After rebooting, my graphics work great without using any "hacked" kexts, which leave me with full acceleration and no artifacts. I assume you can use GFX strings even if you're not using an EFI boot since they're added to the boot.apple. My guess would be that you could get a copy of the default gma950 kexts, install those, and add the GFX strings. However that's just my speculation, so do not sacrifics an install that has important files on it before backing up.

 

Hope that helps
