I'm trying to install Ubuntu 15.04 on a MacBookPro7,1, and have a few questions.
I successfully installed Ubuntu previously, but it failed to boot eventually; there was a purple screen with a black bar in the middle. I had to boot into OS X and nuke the partition via Disk Utility.
I have rEFInd installed.
I figured this was a problem with the graphics drivers, as Linux Mint (an Ubuntu-based distro) had MAJOR problems with graphics. The graphics card is an NVIDIA (I hate NVIDIA ;p) GeForce 320M. Upon installing the drivers on my current EFI install of Ubuntu, I experienced serious problems similar to the ones described here: http://korrekt.org/page/Note:How_to_install_%28K%29Ubuntu_14.04_on_Macbook_7,1
My question is, how do I get Ubuntu running with the proper NVIDIA drivers? I know how to get Wi-Fi working, but not full graphics support. According to the guide linked earlier, I need to get a Ubuntu install running in BIOS mode, but how do I do that? I don't understand the guide.
I'm willing to get technical with this; I need to get away from OS X Yosemite, it runs badly on my hardware.
