It is not a good idea to install Nvidia drivers from .run files, downloaded from Nvidia site. This way they will not be registered properly by dkms and you will get black screen after first kernel update.

Good way to install the driver is to run:

sudo apt-get install nvidia-current

Or go to System Settings -> Software & Updates -> Additional Drivers and install driver from there.

But if you are sure, that you need to do it this way, then here is the command:

sudo stop lightdm
