KDE Display Manager (KDM) is a display manager (a graphical login program) developed by KDE for the windowing systems X11.

KDE Display Manager was based on the source code of X display manager[1] and was the default display manager of the KDE Software Compilation, until it was retired in KDE Plasma 5 in favour of SDDM.[2]

KDM allowed the user to choose a desktop environment or window manager at login. KDM used the Qt application framework. It is configurable via KDE's System Settings; its appearance can be customized by the user.

The default KDM login screen had a list of users. Each entry was comprised in the user's username, personal name (if available), and an icon. Next to the list is a greeting and a picture. One of the customization options is to replace the picture with an analog clock. From this screen the user can also run a user management tool, shut down or reboot the computer, or restart the X Window System.
