Simple Desktop Display Manager (SDDM) is a display manager (a graphical login program) for the X11 and Wayland windowing systems.[5] SDDM was written from scratch in C++11 and supports theming via QML.[6]

SDDM is free and open-source software subject to the terms of the GNU General Public License version 2 or later.[4]

Adoption

In 2013, Fedora KDE members decided to default to SDDM in Fedora 21.[7]

KDE chose SDDM to be the successor of the KDE Display Manager for KDE Plasma 5.[8][9] In 2023, KDE forked SDDM to form the basis of the new Plasma Login Manager, which will become KDE's default login manager starting with Plasma 6.6.[10][11]

The LXQt developers recommend SDDM as a display manager.[12]
