What display manager does Fedora 20 Jam/KDE spin use? (64bit)


I have a bit of a mystery here. Now if you read the title you would assume that it uses kdm. Well... Check this out,

Notice that none of those are installed. I tried to install,

Code:
#yum install switch-displaymanager-gnome
Loaded plugins: langpacks, refresh-packagekit
No package switch-displaymanager-gnome available.
Error: Nothing to do
But as it says, it is not in the yum repos, not even the RPMFusion ones. I did install system-switch-displaymanager but it is useless unless I tell it what to switch to at the command line.

Does anyone know what display manager Fedora Jam/KDE spin is using? I am in KDE right now and there is a display manager working. I get a log in screen and everything. The same one with or without any of the above displaymanagers installed.

Edit: Actually it was named system-switch-displaymanager-gnome. I installed it but I am getting an error,
Code:
# system-switch-displaymanager
Traceback (most recent call last):
  File "/usr/share/system-switch-displaymanager/system-switch-displaymanager-gui.py", line 160, in <module>
    dlg = mainDialog().main()
  File "/usr/share/system-switch-displaymanager/system-switch-displaymanager-gui.py", line 62, in __init__
    self.defaultw = getDefaultDM()
  File "/usr/share/system-switch-displaymanager/backend.py", line 119, in getDefaultDM
    dm = DMLIST[0]
IndexError: list index out of range
It also hangs when I try to start it from Menu>Administration>Display Manager Switching Tool. It asks for the root password, I get a bouncing icon and than nothing. Which I am wondering if it is because it can't find a display manager either.

Other than that error above (and that I am not worried about) I am having no other issues. I just want to figure this display manager thing out. Is there another display manager I am forgetting about? I tried wdm but that is not even in the repos.

Well never mind. Thanks to Arch wiki, and I am using Fedora, I found my answer. https://wiki.archlinux.org/index.php...splay_managers It is using SDDM,

Quote:
Name : sddm
Arch : x86_64
Version : 0.2.0
Release : 0.22.20131125git7a008602.fc20
Size : 632 k
Repo : installed
From repo : updates-testing
Summary : QML based X11 desktop manager
URL : https://github.com/sddm/sddm
License : GPLv2+ and CC-BY-SA
Description : SDDM is a modern display manager for X11 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.
Also, which I was not aware of at all (I really should keep up on this stuff), from Fedora https://fedoraproject.org/wiki/Changes/SDDMinsteadOfKDM

Quote:
As described in many articles and discussions, KDM is nearing its end of life and it's time we decided upon the successor.

I'm proposing to switch to SDDM, which is a new project that suits our needs perfectly despite its immaturity:

As of July 2013, KDM's maintenance consists of bugfixes for the most painful bugs, consisting of only about 20 actual commits to the repository in last two years (excluding translation, themes and merges), adding many new features would require major changes to a lot of the code and there is no active maintainer.

SDDM is written in C++11/Qt5 (compared to the bits of XDM in KDM), compilable against Qt4, supports QtQuick theming and its upstream is quite active.

Compared to the current DM, KDM, it currently lacks a few features (such as XDMCP) but adds some other ones (QtQuick themes) or is currently adding them (Keyboard layout switching in the greeter).
I will mark this as solved and leave it as is incase anyone else ever wonders about this and searches.
