Description of problem:
log in using sddm. log out and the display turns black and stays on vt2. sddm is on vt1. switching with ctrl-alt-f shows this. however, sddm on vt1 shows the blacked-out password and is dead. it does not permit logging back in, shutting down the computer, nothing. the only option is to log in to vt3 or later and shut down or reboot the machine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
switching to gdm solves the problem: everything works as expected.
The very same happens on Fedora 29.
1. Setup sddm; default will do
2. Log in, using gnome, or gnome-classic or plasma (others not tested)
3. Log out
4. The log-out half-succeeds. Some processes remain, the screen
displays whatever was on there before the logout, but is unresponsive.
Real logout needs a 'loginctl terminate-session' ...
sddm is completely unusable. Back to the ancient kdm ...
ctrl-alt-delete seems to work to get back to sddm, but this is not acceptible. I have had reliable results 'reverting' to gdm, both with plasma and plasma (wayland).
PS: I changed this to Fedora 29, since I am now on f29 and the problem persists, to the point of sddm being unusable.
I suspect in at least some of these cases, your user session isn't actually ending (ie, it's a user-session issue, not sddm).
Options that can mitigate that:
* disable session management (which is the plasma default, unless you changed it).
* set in /etc/systemd/logind.conf :

I have it set to start with an empty session. Is this how it should be? It is what I prefer.
> * set in /etc/systemd/logind.conf :
Presently (and this is the default file state), it says:
Hmmm. Does that mean that it is set to yes, and I can uncomment to get no? Or does this mean that it is set to no?
Now, should I (a user) really have to change systemd config files to get standard behaviour that always worked previously (simply ending a user session and returning to the login screen, i.e., to the display manager)?
I am now on fedora 30, so I have no idea if this is still relevant.
It is still relevant for Fedora 30; changed behavior a bit, as it is not always the case (20% maybe).
Happens with both a Gnome and a Plasma session started from sddm.
Running with a default /etc/systemd/logind.conf;
