Version: (using KDE 3.5.9) OS: Linux Installed from: Ubuntu Packages This wish was reported on the ubuntu bug tracker under: https://bugs.edge.launchpad.net/ubuntu/+source/kdebase/+bug/130184 kdm displays a list of users in Ubuntu Gutsy. However, this list includes also disabled users, which does not make sense, because they won't be able to login anyway. (I have two users on my sysem with UID 1002 and 1004 and have disabled them, using the KControl's User Management).
KDM is unmaintained and not used in KDE Plasma 5. SDDM is the login manager used in KDE Plasma 5. If you still have this same issue with SDDM, please file an issue on the SDDM bugtracker (after doing a search for existing issues first!): https://github.com/sddm/sddm/issues/
