Multiple monitors -- seeking advice

Looks like I need to whip out a tighter leash for my multiple monitor setup, as I am having some annoying bugs and inconsistencies in monitor detection and/or general display management. Push come to shove, I may need to write a tiny script to make sure my monitors are detected properly and my monitor arrangement is set to the one I want, so I don’t have to fiddle with it every time I reboot.

So what is responsible for monitor management and detection in CL? Where should I start looking? Where are the monitor and display settings stored please? Using Gnome & Wayland.

this may help
