I don’t get the diff as a noob. I know what plasma and gnome are - desktops. I tried to install i3, a window manager, and it broke my computer so I’m having to reinstall the OS.
What I really want it something that allows me to move windows around like https://www.spectacleapp.com/. It used uses shortcuts and does not slot windows into free space like kwin does. Kwin might have shortcuts for windows moving but they didn’t work out of the box and I don’t need a highly configured version.
So, do I want something like i3 just to be able to move my windows around?
How is a window manager not a full desktop? If it’s not, then what is the desktop if say i3 is installed?
