So tonight, I guess I should try again.. maybe remove and reinstall sddm
and I'd firstly think that installing a few other DM's would be a good idea
but then I'm left with so many other dependencies that I'd be in the same
boat as now. So am I correct in thinking that reinstalling sddm, I will
retry the enable command and see if the results are different this time..
and if greeted with a black screen then journalctl should be my friend.. Oh
and also check that state.conf file to make sure it's not still pointing to
GDM... Is this a solid plan?
