I'm kindof a noob when it comes to Ubuntu/not windows so please pardon my inexperience.
I've been messing around with Ubuntu 14.04 on my Macbook Pro (9,1 mid 2012, non retina), installed as a dual boot with OS X (with rEFInd).
In my noobishness I tried to have a wack at Bumblebee to see if GPU switching would work. Well, now I get a black screen after the purple Ubuntu screen with the dots. It appears the computer is booting up, and if I type my password and hit enter, it appears to login, just there's no video output after the Ubuntu screen, just black.
For reference I was using the most recent nVidia proprietary drivers (331.xx i think) supplied by the "additional drivers" utility. (card is a GT 650M)
Is there any way to uninstall bumblebee/fix this, or should i just give up and reinstall (its not a actively used install, but i have put a good number of hours into configuring it)?
Thanks in advance for any help.
