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]}

The LXQt developers recommend SDDM as a display manager. ^[10]
