It's taken the interest not only of Hawaii but also KDE. They consider using it in Plasma Workspaces 2, see this blog post by Aaron Seigo: http://aseigo.blogspot.com/2013/03/l...kspaces-2.html
Phoronix: SDDM Display Manager Sees Its First Release
Mentioned a few times in recent months on Phoronix has been SDDM, a lightweight Qt/QML-based display manager. The good news now is that the Simple Desktop Display Manager has seen its first official release...
It's actually very nice, I hope they will use it in next KDE Framework (Plasma 2).
Razor-qt has also been looking it. There has already been work to create themes and such to match razor-qt.
Yeap, KDE developers are considering it as the main login manager for KDE. It's either SDDM or LightDM, and both have their issues at the moment. Personally I feel that SDDM is probably better in the long run, as it's built for Qt5 from the ground-up and has no strings attached.
