Looking at the screencap of the terminal session, it seems you're not sure whether you're running a Wayland session or an X session. If you're running a Wayland GNOME session, then the compositor in use will be Mutter, and xrandr won't be applicable, as it's designed for X. wlr-randr, which is not available in the main Gentoo repo, but is available in the GURU repo, is designed specifically for wlroots-based compositors, and Mutter isn't wlroots-based, so that might not work either.
If you're in a Wayland session, then the variable WAYLAND_DISPLAY should have a value; what's the output if you run:
| Code: | | $ echo $WAYLAND_DISPLAY |
? |
