Ok, thanks for the explanation, that makes it a bit clearer. I still wonder which role the xdg-* tools play though. They're CLI-tools written in bash, which one might think are supposed to help non-DE-users deal with those settings, but if you try to use them without a DE running they won't let you. At least that's true for xdg-settings, here's an example: $ xdg-settings --list Known properties: default-web-browser Default web browser xdg-settings get default-web-browser xdg-settings: unknown desktop environment
