If your graphical environment (since you're almost certainly running
with one) is based on the X Window System, you want to look at the
'xrandr' command.

If it's based on Wayland instead, there's almost certainly some
analogous tool, but I don't have enough experience with that stack to be
able to say what it might be.

(If somehow you're trying to do this in a purely terminal-based
environment, with no GUI... that would be interesting, and I have to
admit that just offhand I'm not sure of how to do it. I think I know
where I'd start looking in order to find out, but I'd need to do some
poking around in order to be able to even make any recommendations for
where to look.)
