Public bug reported:
Relying on the nouveau driver and on the vga switcheroo (to get around a
change in systemd LP: #1777099) caused increased power consumption, and
slowed down the switching process.
Solving the problem in systemd (LP: #1777099), and adding code in gpu-
manager and in nvidia-prime to unload the nvidia modules, and to allow
the PCI device to sleep, dramatically decreases power consumption.
