eedd Posted September 10, 2008 Share Posted September 10, 2008 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! Link to comment Share on other sites More sharing options...

eedd Posted September 10, 2008 Author Share Posted September 10, 2008 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. Link to comment Share on other sites More sharing options...
eedd Posted September 11, 2008 Author Share Posted September 11, 2008 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. Link to comment Share on other sites More sharing options...
