Intel GMA x3100 kext?

Question

My laptop has the GMA x3100 in it, and the graphics were fully working on Snow Leopard, but now on Lion 10.7.2, i don't have full graphics support. The resolution is wrong and its not very appealing. The display is supposed to be 1280x800, but the only resolution it has is 1024x768. Anyone have a kext to fix this? Thanks!

First Run this and set Resolution. (don not tick unnecessary options)

Link : Chameleon-2.1svn-r1683.pkg

Restart and see if the resolution gets fixed.

if not keep a backup of originals and paste these two Kexts to \System\Library\Extentions

Link : AppleIntelGMAX3100.zip

repair disc permissions

open terminal an paste this lines:

sudo -s (type :su password after this)

perl -pi -e "s|\x86\x80\x02\x2A|\x86\x80\x12\x2A|g" /System/Library/Extensions/AppleIntelGMAX3100FB.kext/AppleIntelGMAX3100FB

perl -pi -e "s|\x86\x80\x02\x2A|\x86\x80\x12\x2A|g" /System/Library/Extensions/AppleIntelGMAX3100.kext/Contents/MacOS/AppleIntelGMAX3100

perl -pi -e "s|028086|128086|g" /System/Library/Extensions/AppleIntelGMAX3100FB.kext/Info.plist

perl -pi -e "s|028086|128086|g" /System/Library/Extensions/AppleIntelGMAX3100.kext/Contents/Info.plist

touch /System/Library/Extensions

Hello,

You should try this :

Download X3100 64bit driver (for snow and lion) from here

install it as described (the Recommended smbios.plist change is not necessary)

then download this very good utility Chameleon Wizard (google it)

Open it and in the menu "org.chameleon.Boot" disable Graphics Enabler

Reboot

and Voila!

Launchpad runs smoothly but no transparency in menubar => No QE/CI activated

You welcome,

I don't think so.

There is no evidence of that but if you see how to, please tell me.
