kextstat shows AppleIntelFramebufferCapri.kext loaded but not showing AppleIntelHD4000Graphics.kext

Can you verify if AppleIntelHD4000Graphics.kext & AppleIntelFramebufferCapri.kext are in /System/Library/Extensions?

what did you patch on your DSDT?

what's the source of your installer? is it a Distro or vanilla install?

can you run this in terminal and post the result?

      sudo chmod -Rf 755 /L*/E*

      sudo chown -Rf 0:0 /L*/E*

      sudo touch -f /L*/E*

      sudo chmod -Rf 755 /S*/L*/E*

      sudo chown -Rf 0:0 /S*/L*/E*

      sudo touch -f /S*/L*/E*

      sudo kextcache -Boot -U /
