Installing NVIDIA driver causes black screen (750M)
Solution 1:
Quick googling gave me this 319.17 Certified
Added support for the following GPUs:
GeForce GTX 650 Ti BOOST
GeForce GT 720M
GeForce GT 735M
GeForce GT 740M
GeForce GT 745M
GeForce GT 750M
So you'll probably need 319.17
It's from 2013.05.02 and not yet in any official Ubuntu repository.
To install it, first remove the ones you installed from the repo's sudo apt-get purge nvidia*
(or --purge remove) should do that. If you installed one manually, please look up how to remove them.
Then follow: Install New Nvidia Drivers, Nvidia 319.17, on Ubuntu 13.04 Raring Ringtail
