LightDM (for example) combines some of this "under one roof/umbrella/[process?]": "LightDM is a lightweight, cross-desktop display manager. A display manager is a daemon that: Runs display servers (e.g. X) where necessary. Runs greeters to allow users to pick which user account and session type to use. Allows greeters to perform authentication using PAM. Runs session processes once authentication is complete ..." but I don't think my point re indication of config issues is affected, is it?
