Display manager
I thought the d stood for Desktop, but i'm thinking of de, i see i've been mixing up terms, i've also been under the incorrect understanding that window managers and desktop environments were mutually exclusive, e.g. a desktop environment like xfce would conflict with a window manager like i3
Those scripts look cleaner than mine, perhaps i should give it another go, i'm currently on ubuntu, but many of the packets being 15 years out of date is starting to get annoying, i miss aur with its [xxx]-git packages
