Developed for the display settings page, and compatible with all Wayland compositors which support the wlr-output protocols, cosmic-randr is a new Rust library and command line utility for displaying and configuring display outputs on Wayland desktops.
Nice, i’ve been doing this with a python script that emulates randr functionality. Would like something a bit more robust. However it works for my need. Will link it if i remember just incase someone is interested.
Here it is.
