GTX 1650 and GT1030 drivers for Ubuntu 18.04

I’ve a new computer with two graphic cards: GTX1650 and GT1030.
After installing their drivers using the terminal with:

sudo ubuntu-drivers autoinstall

The operation system won’t load. Is there something that I am missing?

Do you get to a command prompt? Can you use ctrl+alt+f1 to change to a VT?
