[ubuntu] Retina MacBook Pro dual graphics fix

Hello everyone, I have a retina MacBook Pro (Mid-2014) dual booted with Ubuntu 14.04 and Yosemite. I am using rEFInd as the boot loader. Ubuntu only recognizes the nvidia GPU and not the integrated GPU, I can't find a straight answer on how to solve this. Also the nvidia gpu is causing the system to be hot (I think). After installing bumblee the Maximum resolution is 1024x768. Can someone please help me? I like Ubuntu but it is truly a pain on a MacBook.

thanks.
