I wonder if this is related.  When I did my switch, I hit a point where
I had to start the alt sysreq key sequence.  I only had to do the R and
E part to get my console back tho.  At the time, I thought it may just
be some weird occurrence but now I wonder if it was related to some
update.  Once I got my console and login screen, I was able to login and
carry on, after getting all the services back running that got killed
off.  I got the login screen back after hitting the E part. 

I wonder, will others run into this sort of problem?  If so, what is the
best way to get back to normal?  For you, rebooting helped.  For me,
just starting the alt sysreq did the trick.  It makes one wonder.
