Recent Ubuntu releases use Wayland instead of X11 and so do other recent distributions other than Ubuntu. This tutorial uses "xrandr" which is X11 only tool.

For Wayland you should adapt the instructions using wlr-randr or gnome-randr or something equivalent, but do not assume the syntax is the same as with xrandr.
