Currrently there is an issue with some laptop GMA950s where if:

a.) You use the regular AppleIntelIntegratedFramebuffer.kext, you get a black screen startup and the only solution is to plug an external monitor in OR you initiate the display to sleep and then kill it.

b.) You use the fixed AppleIntelIntegratedFramebuffer.kext, and everything works fine, except you get some annoying cursor artifacts on the screen.

I hate having to manually put the display to sleep, and i'd rather use one of the corners for something else :-P - so I made a small service that starts up right before login kicks in or before you autologin to your desktop. So far I have used it on 2 different laptop and it does an amazing job. I need some more people to test it out on theirs.

link 1: GMA950_Fix.pkg.zip (Updated)
link 2: (Updated)

If you notice, after you install the pkg there is a GMA_Backup.tar.bz2 sitting in the root directory (/). if this installer {censored}ed everything up - you just need to extract that as root (cd /; tar xjvf GMA_Backup.tar.bz2) go into it and run the Uninstall script as root (cd /GMA_Backup; ./Uninstall). everything will be back as it previously was.

This is new and its just a quick fix for now! Those with issues with their laptops GMA950 try this, especially the dell laptops.

My plan is to add support to this to fix the resolution changing problems. I will keep up with info on how far I am from being finished.

UPDATE: looks like I need to move it over from SystemStarter to launchd since they slowly got rid of SystemStarter usage, which makes sense why it delays on some systems. I'm gonna see what i can do with the code without modifying loginwindow itself

Hi nawcom!
Thanks for the trick for the GMA 950 wake from sleep issue! I m using it for my Dell Inspirion 640m with 27A2 GPU. Unfortunately, it does not work in snow 10.6.3. I have this error message in my logs :
5/4/10 7:49:21 PM	SystemStarter[22]	/Library/StartupItems/GMA_Sleep
5/4/10 7:50:42 PM	SystemStarter[22]	GMA950 Startup Utility (83) did not complete successfully

Please could you recompile/update for snow ? Or I m missing something ?
Thanks for your help

Hi everyone,

I would like to share with you my issue as I didn't find anyone talking about it anywhere ...

I have installed snow leo on my NC6400 with iHazard. Even in the final version which now include driver for the GMA950, driver are not working. I guess they still not work for those who have a GMA950 0x27a2.
So I have some drivers for GMA950 working as I can have the 1280*800 reso which is good.

But my problem is that it gives me trouble with WORD and other office stuff but mainly with word.
I tried with OFFICE 2004, 2008 and even 2011 beta 2. The issue is that WORD is managing the cursor pointer and it has problem to change it so the cursor freeze, or double itself regarding where the mouse is on :
- on a graphic : no problem
- on cells : no pb
- but on text : bingo. So it is hard to select text or to click in the text ... A trick is to right click to have a popup then move the mouse which in that case move ok with the popup opened and then click where you wanted in the text.

I tried the different version of office without the GMA950 installed so with the basic 1024.768 reso and word has no problem to manage the ursor pointer. So really it comes with the GMA950 driver.

Anyone has working with GMA950 (0x27a2) + Word 2008 (don't like the 2004) + Snow leo 10.6.2 or 10.6.3 ?
If yes, any chance to share the drivers ... ?


ps: i have often some application crashing and don't know if it is not due to the GMA driver also ...

Thanks for your help

this is a well documented problem and all over the place for the gma950, nothing new. You are using an incorrect intelappleframebuffer.kext that leads to artifacts.

running 10.6.3 here with gma950 0x27a2 and stock drivers. no artifacts.

good luck

Hi I'm new to all of this, never considered my self to be that great with computers before this week!
I have a Dell latitude d620 graphics card intell 950gma, kalyway 10.5.2.

Basically had every thing working; sound, wireless, usb (after installing a new network card a variety of kexts).

But i got cocky and thought I'd try fixing the fuzzy resolution (I only have options of less than 1024x768 and I need 1280x800) after using the kext helper to install this kext http://www.insanelym...howtopic=143340 (v3) I rebooted (yes I know i should have performed some intermediate steps but I didn't because I'm an idiot, I also know now ths s not designed for laptops... so lets except that and move on...)

I'm at my wits end because when I boot now all I get after the apple loading screen is complete black. Please help! I have assignments on that computer that are due next week and no way of accessing any of my files etc. I've tried booting in safe mode, to no avail.

I'm happy to keep the fuzzy resolution, I just want my screen back!

PLEASE HELP!

ps. I wish I'd found this fix prior to installing the the one which I did... but now I need my screen back and then I can try this fix.
