Same here, Asus N550JK with Nvidia 850M. After switch to Intel by
Nvidia-prime and restart, I can see huge consumption, around 22W. When I
disable nouveau completely, by disabling the Nvidia fallback service and
then turning off the GPU using old bbswitch, I get 11W which is normal
for this laptop
I have the same issue. Ubuntu 18.04 with Nvidia 1070 MaxQ GPU. Have switched to
intel GPU but still powerdrain is enormous so obvioulsy the nvidia card is
still in use.
Powertop show me that the network interfaces wlp3s0 (iwlwifi) drains around 14W
which cannot be true. So it also can't detect
Confirm the issue seems everybody on 18.04 and Nvidia GeForce is
suffering...
Duplicates ?

This bug was not fixed. It still affects me. The GPU doesn't go off, so
the power consumption remains pretty high (and the fan keeps on going).
