To add to this: Wayland is a bit different than X11. In X11 you had split responsibilities: Compositing, X Server and Window Manager. Wayland only refers to the protocol and compositors implement that protocol. So Hyprland is a compositor which implements the wayland protocol. The compositor has a lot more responsibilities in wayland since it needs to do everything itself which in X11 was split across different applications.

Here’s a neat site for the wayland protocol: https://wayland.app/protocols/

For the IP issue: You can look into some service which automatically updates your domains DNS. It’s been a while but back then one of those was DynDNS, not sure if they still exist, but others surely do.

Same here. Been using KDE daily since around 2016/2017 when I switched to linux as my desktop. I tried every other DE there is and was never satisfied. Happy to see kde moving here
