I apologize, sort of, for the diatribe which follows.  Please understand that it is a
general rant while, unfortunately, using examples from this thread.

A solid plan would be to answer *specific* questions with *specific* answers to those
trying to assist.

I speak only for myself.  When I ask a question I ask it with a foundation.  I may,
or may not, go into detail as to the foundation behind my question.  The reason for
that is the foundation may be complex and time consuming to write out.  And, I have
found that many people aren't interested in the ramblings of my thought process they
are only interested in results.

With that in mind, here is an example.

I asked the simple, yes or no question.  "Are you getting a login display?"  I did
layout a brief foundation behind my question.  Maybe I should have added that in
looking at the logs I also saw...

Jan 25 19:50:19 Vostok audit[1937]: USER_START pid=1937 uid=0 auid=1000 ses=2
subj=system_u:system_r:xdm_t:s0-s0:c0.c1023 msg='op=PAM:session_open
grantors=pam_selinux,pam_loginuid,pam_selinux,pam_keyinit,pam_namespace,pam_keyinit,pam_limits,pam_systemd,pam_unix,pam_gnome_keyring,pam_kwallet5,pam_kwallet,pam_lastlog
acct="bhart" exe="/usr/libexec/sddm-helper" hostname=? addr=? terminal=:0 res=sucess`

And auid=1000 is "actual user ID" which is the numeric ID of the user contained in
the /etc/passwd file.

So, one of two things can be happening.  Either one is getting a login screen and
typing in a password *or* at some point the system has been configured for "auto-login"

The answer to the question "Are you getting a login display?" resolves that.  And
that question remains unanswered.

I also asked the question (paraphrased here) "Do you have a /var/lib/sddm/state.conf
file.  If so, what are the contents."  A specific question which would have a
specific answer along the lines of....

[root@acer ~]# cat /var/lib/sddm/state.conf
[Last]
# Name of the last logged-in user.
# This user will be preselected when the login screen appears
User=egreshko


# Name of the session for the last logged-in user.
# This session will be preselected when the login screen appears.
Session=/usr/share/xsessions/plasma.desktop

I can only guess what is in it since you used words to indicate there may be Gnome
stuff in it.  Then my advice would probably have been to either delete the file or
change the "Session" contents.  I *also* would have gone on to explain that erasing
and re-installing the sddm package would probably *not* remove that file.  That file
is *not* supplied by the package but created by running sddm and those types of
"info" files are generally not removed.  So, an erase/install would be ineffective.

You have added a message to this thread talking about "system-switch-displaymanager
<https://apps.fedoraproject.org/packages/system-switch-displaymanager>".  That
command is nothing more than a shell script.  And, an unnecessary one at that.  The
bottom line is that it performs two commands.

rm -f /etc/systemd/system/display-manager.service
systemctl enable $DM.service

This is, in effect, the same as "systemctl -f enable sddm".    If that command
"fails" to do what it is intended to do and doesn't provide an error message would be
a source of concern to me.


Sorry for the rambling nature of the above.  Full disclosure, I was out late last
night  eating and drinking.  With the emphasis on drinking.  I woke up early as I
needed to.  So, I am not hung-over since I still have plenty of alcohol in my
bloodstream.
