My problem is known, but still remains unsolved. After installing the latest (or any other version) of Nvidia drivers I get black screen or am unable to login.

- Nvidia driver version is

I can switch (visually) between via nvidia-prime
and Nvidia X Server Settings now, though before it was impossible due to different problems like this.
I've tried to install the latest drivers from official page, but get the same.
