INTRODUCTION

SDDM is a modern display manager for X11 and Wayland aiming to be fast, simple and beautiful. It uses modern technologies like QtQuick, which in turn gives the designer the ability to create smooth, animated user interfaces.

SDDM is extremely themeable. We put no restrictions on the user interface design, it is completely up to the designer. We simply provide a few callbacks to the user interface which can be used for authentication, suspend etc.

To further ease theme creation we provide some premade components like a textbox, a combox etc.

There are a few sample themes distributed with SDDM. They can be used as a starting point for new themes.

INSTALLATION

Qt >= 5.3.0 is required to use SDDM, although Qt >= 5.4.0 is recommended.

SDDM runs the greeter as a system user named "sddm" whose home directory needs to be set to /var/lib/sddm.

If pam and systemd are available, the greeter will go through logind which will give it access to drm devices.

Distributions without pam and systemd will need to put the "sddm" user into the "video" group, otherwise errors regarding GL and drm devices might be experienced.

TROUBLESHOOTING

    echo running NVIDIA Prime setup /sbin/prime-offload, you will need to manually run /sbin/prime-switch to shut down
    /sbin/prime-offload
