Simple Desktop Display Manager (SDDM) is a display manager (a graphical login program and session manager) for the X11 and Wayland windowing systems.[4] SDDM was written from scratch in C++11 and supports theming via QML.[5]

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


In 2013, Fedora KDE members decided to default to SDDM in Fedora 21.[6]

KDE chose SDDM to be the successor of the KDE Display Manager for KDE Plasma 5.[7][8]

The LXQt developers recommend SDDM as a display manager.[9]
