Phoronix: SDDM 0.20 Display Manager Released With Experimental Wayland Greeter

SDDM as the QML-based X11 and Wayland display manager commonly used on KDE systems and elsewhere is finally out with a new release...

Funny thing is that some distros (e.g. Arch or Fedora for sure) have been pulling git for a long time now. So the change is not as drastic as it may sound

I don't know whether that's the most important thing about this release. Iirc 0.20.0 was supposed to add the ability to run X as non-root. That would be biggest addition, if it was merged.

Finally. Previous release was almost 3 years ago.

Not Arch - it has 0.19 in repo with couple of patches and not some git version. Anyway I am happy that will be fixed soon.

Shame on me - I take it back.

Seems it was merged and released with v0.20.0 https://github.com/sddm/sddm/commit/...92b08b2d2f6046

There are other notes referencing "x11 user" in the release too.

I gave up on using SDDM or any other graphical greeter because of the X11 dependency requiring the installation & use of the full X server (not just XWayland). Now that it's gone I might be interested in SDDM again.

Been riding git-master with Wayland greeter for a few weeks now and it actually "just works".
Consumes ~6MB of RAM, no xserver running. Kinda impressive.

If there's no separation between the display server and the window manager and the Wayland world is still dragging its heels on a mechanism for privileged clients and security-sensitive portions of the API surface (GNOME's excuse for baking so much into Mutter), how does SDDM set up a kiosk-mode interface without opening up users to "Give me your credit card number to unlock your screen"-style attacks from regular clients in desktop sessions?

Is there a KWin-specific Wayland extension for negotiating privileged client status that I missed?

But but but… SDDM was dead, right?
