Hi Jack,
If your goal is ensure that the dGPU doesn't go to sleep, you can boot with "nouveau.runpm=0" which should disable the go-to-sleep stuff, I believe.
Depending on how things are wired up, it may not be possible to drive all display on the igpu from the dgpu with Xorg. Xorg is generally set up to allow you to render some things from the secondary GPU using DRI_PRIME environment variable. This could even be the compositor, if you're using one. Although more common is to do it for specific applications.

G'day,
I'm configuring my xorg.conf to set my dGPU as the main GPU because my
laptop's fans aren't supported and the GPU fan is really important for
the thermals. The CPU fan sucks air from the base, and the dGPU fan
pushes it out the back.
It's an Inspiron 15 7000 which isn't support by i8x as far as I could tell.
So I'm wondering, is there a list of options that nouveau can understand
from xorg.conf, in particular something to control switcherooctl like
how nvidia has PrimaryGPU?
I want to try out light gaming with nouveau on the 1050Ti before I mess
with nvidia again.
Cheers,
