You can also do alt+left/right if you're already on a tty :)
Arent you always on a tty though (unless youe sshd or something)
I thought you should use display server when you have dedicated GPU as the display server configures power save and power state while TTY doesn't, at least by default. For me nvidia-smi reports 100W in TTY and ~20W on X
Display servers don't configure power settings, but desktop environments can. You can enable them while in a TTY.
hm, maybe my terminology is off. But alt+left/right won't work from X11 or Wayland
