Will explore “loginctl”; Thanks Hendrik!
I had one success instance with “init 3 && init 5” with “xdm” but other than the login screen, I could tell no difference from SDDM. I had trouble rebooting too.
However, I went on to screw it up so bad that I will have to re-install: Did a zypper dup & removed the bumblebee & suse-prime-alt rpms to change them and could not get the intel video back.
Tumbleweed is up to 20161210, so I don’t mind starting fresh as this intell i7-6700 cpu installs it PDQ (pretty darn quick)!
