How to boot to text only mode? Problem with laptop with Nvidia GPU

I have a new laptop with Nvidia GTX 1070. After the grub menu and the splash screen the monitor goes black, but I can see the Ubuntu welcome sound.

I tied boot options like nomodeset, nouveau.modeset=0, text, forcevesa without any difference. However, it looks like there is a small chance that the monitor will go live. This allowed me to actually install the Ubuntu 16.10. And once I reached the login screen. After entering the password the screen freezed again.

I cannot get access to the virtual terminal (Ctrl + Alt + F1) either.

I want to try to install Nvidia proprietary drivers. Is there a way to boot to console only mode?

The problem solved by disabling "hybrid" graphics in BIOS. Precisely, I found a switch in BIOS with options: MSHybrid (default) and DISCRETE. Selecting DISCRETE allowed be to login to Ubuntu. It looks like the problem is in Intel and Nvidia GPU cooperation, not in the Nvidia GPU itself.
