Intel GMA950 not working after update

[eedd]

Hi everyone,

I have an acer laptop with an intel gma950 display adapter that works fine with the GMA950 driver from the kalyway 10.5.2 cd. When I update to 10.5.3 using the kalyway comboupdate however, the machine boots up but it will only show a blue screen. This happened before when i didn't select the GMA950 driver during installation.

 

My question is how do I restore the old driver? I backed up my kexts, so my first thought was to replace everything with GMA950 in it and the AppleIntelIntegratedFramebuffer.kext. I tried to do that but it didn't seem to have any effect.

 

It's possible I did it wrong though, could someone give me a rundown of the steps to replace the kexts or point me to a relevant thread? Or is there a kext that I am missing that also needs to be copied over.

 

Thanks!

Hi, Before U post U should search. Check out point 4.

Thanks, but how do I install the kext. Can I copy it to a flash drive and then copy it to the extensions folder? If so how do you do that from single user mode because the flash drive isn't mounted automatically I don't think.

 

Second how do you repair permissions manually because diskutil is not available in single user mode?

 

Thanks.

Nevermind, I found this that should help.

How do I install kexts (Kernel Extensions)?

 

The easiest way to install kexts (Kernel Extensions, usually some sort of driver) is to use a helper application like Kext Helper that automatically installs the kexts for you. The other way is a manual method: Put the kext you want to install on the Desktop. Next, if you are planning to replace a kext that is already installed with a different version, run the following commands from Terminal (Applications >> Utilities) to back it up:

 

sudo -s
[enter password]
mkdir /KextBackup/
cp -R /System/Library/Extensions/name_of_kext.kext /KextBackup/

 

Once you are done backing up (or if you are installing a completely new kext), after making sure the kext is on the Desktop, run these commands with Terminal:

 

sudo -s
[enter password]
cp -R ~/Desktop/name_of_kext.kext /System/Library/Extensions/
chown -R root:wheel /System/Library/Extensions/name_of_kext.kext
chmod -R 755 /System/Library/Extensions/name_of_kext.kext
rm -rf /System/Library/Extensions.mkext

 

Replace "name_of_kext" in these commands with the actual file name of the kext you are installing. Reboot for the changes to take effect.

 

I'm going to try replacing the kexts using those commands.
