Coming from traditional distro (Arch to be specific) I just install it without DE or uninstall the existing one and install the other. Graphical environments are just programs just like any other.
So those images are just a convenience thing? Like Fedora has spins that preinstall desktops to have them out-of-the-box?
How those distro are displayed in (neo)fetch like programs, are they just Fedora or their own thing?
