This did not fix it. It's really a bug with sddm.
I agree there is a problem but not 100% sure it is sddm.
I have a similar and may be the same problem.
I use multiple users to isolate work from play and I have had issues
with one account that when I logout, it freezes with the background
showing. Mouse moves but nothing works in it.
There are enough processes running and I go into another account and
slowly kill them off. I have had KillUserProcesses=yes set for a very
long time on this machine.
The last process I end up killing it the sddm-helper session for that
I have had this on both F31 and F32 but have not had the time or energy
to try to do any debugging on it.
I have it set to start with an empty session.
On logout it freezes.
Other accounts don't freeze like this on this machine. I have another
account that I have never had freeze up this way.
Under top, these are the processes that are running for this user after
an attempt to logout.
gconf-helper will remain a zombie until pulseaudio is killed.
I think there is a process that cannot be stopped and is preventing sddm
from working properly.
I usually have at least two different session open on this machine at
all times and will open a third and/or fourth session from time to time.
