Title:
nvidia-prime is no longer able to turn off the discrete GPU
Status in nvidia-prime package in Ubuntu:
Confirmed
Bug description:
Since updating to Ubuntu 18.04 from 17.10, the discrete GPU is no
longer turned off.
I see since https://bugs.launchpad.net/ubuntu/+source/nvidia-
prime/+bug/1757180 the way to turn off the discrete GPU has been
changed, I suppose that's what caused the regression.
My laptop is a ThinkPad W541, with a NVIDIA Quadro K2100M.
