nvidia-fallback.service loads nouveau when I switched PRIME to Intel. I also see nouveau in `sensors` output. `systemctl disable nvidia-fallback` seems to cure the ptoblem, nouveau kernel module is not loaded any more and power cosumption _seems_ to be lower.

nvidia-fallback.service loads nouveau module even when it's blacklisted because this service starts after systemd loads kernel modules according to configs in /etc/modprobe.d/

Other PRIME fuctions work correctly except switching being much longer than it was before upgrading to bionic (18.04).
