NVIDIA Optimus

Right so while I'm not exactly a newbie anymore I'll write this here even so since I might as well be with regards to handling graphics hardware...

I recently set up my laptop to use Optimus instead of just the discrete NVIDIA card. This works just fine (a GNOME 3.26 bug notwithstanding), but I've had trouble using the Intel GPU only.

My BIOS allows either Hybrid ("MS Hybrid") or Discrete. I have no option of disabling the NVIDIA card altogether in BIOS, so if it's at all possible to do this it'll have to be in software.

I guess the question really is... will I be able to shut down the discrete card completely, or does the monitor being connected to the NVIDIA GPU mean I have to keep it running?

And, if the former is true how would I go about that? I've tried blacklisting the nvidia modules and setting up an Xorg config file to use Intel only but have had no luck.

My laptop is a Clevo P651RP with:
Intel i7-6700HQ
GTX 1060

My Xorg log on discrete is https://paste.fedoraproject.org/paste/C … i2WZh82ohw

Follow this: https://wiki.archlinux.org/index.php/Bumblebee I'm not sure if the monitor part might become an issue, but it wouldn't make much sense to implement a Hybrid Solution and then not being able to power down the discrete GPU. The monitor is likely hooked up to both cards.

Just to be clear, my only option is to make use of Bumblebee? I can't force Intel-only via drivers alone? (By that I mean in theory, assuming a hardware architecture which allows it.)
