F21 Self Contained Change: SDDM as the default KDE display manager instead of KDM

[Jaroslav Reznik]

= Proposed Self Contained Change: SDDM as the default KDE display manager 
instead of KDM = 
https://fedoraproject.org/wiki/Changes/SDDMinsteadOfKDM

Change owner(s): Martin Briza <mbriza(a)redhat.com&gt; & KDE SIG

Retire KDM as the default display manager of the KDE Fedora Spin in favor of 
SDDM.

== Detailed Description ==
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). 

== Scope ==
* Proposal owners:
** Create sddm and sddm-kcm packages.
** Change kde-settings and the spin-kickstarts to provide SDDM package instead 
of KDM
** (eventually) exclude KDM from the kde-workspace package 
* Other developers: N/A (not a System Wide Change)
* Release engineering: N/A (not a System Wide Change)
* Policies and guidelines: N/A (not a System Wide Change)

Could you elaborate how this would impact using GDM to boot into a KDE
session?  From a packaging perspective, would KDE now Require SDDM or
would it be possible to install it without having SDDM installed?

KDE itself doesn't require a specific DM, any DM is fine. There is no  
impact on GDM.

The proposal is only about replacing KDM with SDDM by default on KDE 
installations. It does not affect starting KDE Plasma from non-KDE display 
managers (such as GDM) at all. And even KDM should still continue to work 
(at least for now). Only the default is going to change.

Does scope need to include a specific plan to deal with this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1034414
since failure to login is worse than any bug in KDM?

I can add it, you're right this is an important task before we can ship  
the DM.
