Public bug reported:
When I reboot or shutdown my computer, SDDM tries to restarts itself and
slows down the halting process (by about five seconds).
`journalctl -b-1 |grep sddm` gives:

It can be seen that the system went for shutdown at 14:20:14, got mostly
shut down at 14:20:15 but then spent 8 seconds while SDDM was trying to
start again.
I am on Kuubntu 21.10, I am using systemd-boot to start up my computer
but this also happens to people with GRUB2 as confirmed here:
https://www.kubuntuforums.net/forum/newbie-support/help-the-new-
guy/659089-slow-shutdown?p=659107#post659107
A workaround was messing with /etc/systemd/system.con and tuning down these
values:
DefaultTimeoutStartSec=1s
DefaultTimeoutStopSec=1s
DefaultStartLimitIntervalSec=500ms
Changing the restart values in /usr/lib/systemd/system/sddm.service on
the other hand has not changed anything.
