Description Andre Robatino 2013-09-10 15:20:51 UTC

Description of problem:
[root@localhost ~]# system-switch-displaymanager sddm
The graphical display manager sddm is not supported yet.

I can switch to sddm manually using systemctl commands. Since sddm is now the default DM for KDE, this really should work.

Version-Release number of selected component (if applicable):
system-switch-displaymanager-1.3-3.fc20.noarch

Comment 1 Bas Mevissen 2015-02-25 16:16:20 UTC

SDDM support is now added to system-switch-displaymanager-1.4-1. Unfortunately, with (at least) sddm-0.10.0-3.fc21 on a Fedora 21 x86_64 system it gives the following error:

ERROR: SDDM is not installed on your machine! to install SDDM, please type yum install sddm

The reason for this error is that system-switch-displaymanager looks for the sddm binary in /usr/sbin instead of /usr/bin.

Fix is:

With this change, SDDM is supported properly on Fedora 21.

Comment 3 Jean-Paul Lambrechts 2015-04-05 05:21:58 UTC

Current available version of system-switch-displaymanager in Fedora 21 is 1.4.1 and it appears to still have this bug. There is a simple workaround: 
in /usr/share/system-switch-displaymanager/system-switch-displaymanager-helper,
line 64, in the test for sddm availability, replace /usr/sbin/sddm with /usr/bin/sddm. It does the same thing as the patch from Bas Mevissen.
The switch to sddm works after this change (tested with the gui).

Comment 4 Bas Mevissen 2015-04-07 09:12:22 UTC

There is a newer version (1.5-1) in Koji that seems to have the issue fixed. See http://koji.fedoraproject.org/koji/buildinfo?buildID=615547

This package is fine too on fc21 (tested it myself). It just needs to tagged as fc21 update. Ngo, can you please do that anytime soon?
