I'm not aware of which applications are users of systemd services. So I
installed (using dnf) about a dozen of the applications I usually use,
checked them for basic function, and then removed them. I then
re-installed them and check for basic function again. I found no
problems. I also checked out the functions in the settings panel and
Gnome Tweaks. Again everything worked fine.
Have a Great Day!
