I installed Ubuntu alongside OSX on my Mac, and everything seemed to work fine at first. After 4 or 5 boots, I started experiencing some weird graphics discoloration issues making Ubuntu nearly unusable.
I managed to perform some updates, including an NVidia update, after which now the screen shuts off during an attempted boot and just hangs.
I have rEFIt installed, and I am able to boot into OSX from rEFIt just fine, however Ubuntu will no longer boot.

Let me know if I forgot any other info, thank you.
