Comment 37 for bug 1758243

A followup to the above (#36):

I think that my kernel might be switching the card on and off successfully, w/out the use of bbswitch. If I `optirun glxgears`, I can see the card being used via nvidia-smi (and via a sensors plugin I've got running in gnome). When I close the process, nvidia-smi reports the card as off.

In short: the above instructions worked for me, after turning bbswitch off, due to the 5.0 kernel recognizing my MX150 and switching it on/off as appropriate.

That's pretty darn cool!
