how to apply nvidia settings from the command line?

[Gérard BIGOT]

try

sudo nvidia-setings

from a terminal session.

Then make your changes and press the button that commits it to xorg.conf

It'll persist.

I don't know why it's not by default launched as root.

And I know, it's not a direct reply to your question, but I believe it
solves the root cause of your trouble.
