Blank Screen after trying to install nvidia proprietary drivers

I tried to install the nvidia-331 drivers but as usual it doesn't want to work... I get a blank screen when I boot up.

I tried the instructions here Blank screen after installing nvidia restricted driver but that didn't help

I was actually able to load the driver with jockey-text and startx worked, but obviously no unity or any windowing... I started it from recovery mode.

Hopefully someone can help before I have to reinstall the OS again.. sigh
