I don't know anything about capabilities of our driver w.r.t. scaling, but
what happens if you try to keep everything at 100%?

It's possible what you're trying to do is just not supported by GNOME,
Wayland, Xorg, and/or our driver.

So here's the problem.  If the proprietary driver doesn't work, then there's
no hope for Nouveau working.  That's because the GSP-RM firmware that
Nouveau depends on *is* the Nvidia proprietary driver.

I hate to say this, but you're going to have to work with your laptop vendor
and/or Nvidia support to get the proprietary driver working first.
