Options for xorg.conf supported by driver

[Ilia Mirkin]

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.

Cheers,

  -ilia
