With the KDE5 / Plasma5 Desktop, has KDE a new Display Manager named SDDM short for “Simple Desktop Display Manager”.
Simple Desktop Display Manager (SDDM) is a display manager (a graphical login program) for the windowing systems X11 and Wayland. SDDM was written from scratch in C++11 and supports theming via QML.
SDDM is free and open-source software subject to the requirements of the GNU General Public License version.
The Reason was “Original Quote from David Edmundson’s Web Log”
KDM was dropped from Plasma 5. KDM includes code from XDM dating back to 1988! It had served it’s job well. However, we’re now at a point where we need the backend to be Wayland ready and we want to use more modern QML in the front end. When you have to replace both the back and front ends, it’s a sign to just start from scratch.
There was some work done 2 years ago into sharing code with LightDM. In the meantime a separate project was started, SDDM which is (yet another) display manager.
Although personally I was very happy with what we had with LightDM it definitely doesn’t make sense to split resources, so we focussed everything on SDDM and I have been helping work on that transferring knowledge from my old project.

So now has arrived SDDM Pisi Linux 2.0 and you know not how can you make settings there, you can configure SDDM in Pisi Linux 2.0 in the System-Settings.
Go to Menu>Settings>System Settings when it is open go to Startup and Shutdown “Login Screen (SDDM) there can you set your default Theme and when you click on Advanced,
