Configuration in "/etc/sddm.conf.d/" isn't considered

[vindicatorr]

I had mistakenly posted to https://bugs.kde.org/show_bug.cgi?id=435093 and found at the bottom of the sddm man page, this is the place for it to go.

Name : sddm
Version : 0.19.0-4

The configuration file is /etc/sddm.conf.d/default.conf copied from /usr/lib/sddm/sddm.conf.d/default.conf.
Just make any change to /etc/sddm.conf.d/default.conf that you'll be able to see visually, like the "Theme":

[Theme]
# Current theme name
Current=elarun

Just make sure /etc/sddm.conf/default.conf doesn't exist.

SUMMARY
sddm doesn't look in "/etc/sddm.conf.d" for .conf files.

STEPS TO REPRODUCE

1. Copy /usr/lib/sddm/sddm.conf.d/default.conf into /etc/sddm.conf.d/
2. Make a change you'll be able to recognize (eg. theme)
3. Restart sddm

OBSERVED RESULT
The change in the .conf will not be reflected in sddm.

EXPECTED RESULT
sddm will look in /etc/sddm.conf.d/ and load any configuration in there.

ADDITIONAL INFORMATION
man sddm.conf.5 mentions the search order for configuration files as:

1. /usr/lib/sddm/sddm.conf.d
2. /etc/sddm.conf.d
3. /etc/sddm.conf

#2 is ignored. If I take that same changed conf from #2 and put that in #3 (where #3 didn't exist previously), it will load it then.
