I've been attempting to use caffe on my laptop and have been having problems installing the nvidia drivers (needed for the CUDA toolkit).
Unfortunately after switching to nvidia drivers in the "additional drivers" menu and rebooting, I get a black screen. I can still open the tty, however none of the solutions posted online have actually worked. (Most of them weren't even accepted by the OP too.)
Supposedly what I am supposed to do is install bumblebee, which installs fine without breaking ubuntu, but according to other threads here the proprietary nvidia drivers are needed to use cuda.
What am I doing wrong here?
