You have secure boot enabled so the nvidia driver doesn’t load since it isn’t signed. Please disable secure boot in bios.

I have the same issue.

output from nvidia-smi:
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

output from nvidia-settings:
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system

Secure boot is disabled, os Ubuntu 18.04. I tried multiple drivers, installation through Software & updates or through apt-get, spent 7 hours trying everything. Absolutely no result. Please save me.
