I am using a MSI Apache Pro GE62-2QD with Antergos and systemd-boot.
I use the Bumblebee widget for Plasma 5 to see my card status. When I start my machine and log in, it always shows that it is on and displays the output
$ optirun --status Bumblebee status: Ready (3.2.1). X inactive. Discrete video card is on.
I have been looking around in the arch wiki, adding a systemd-service called nvidia-enable, and it is not working.
When I run optirun on say dolphin-emu, it works fine but the card will never power off after closing the application using the GPU.
