Well, reporting back, and I'm not 100% sure what caused my problem. I 
have used several repos since I installed the box two years ago, and 
there was quite a bit of clutter.  I'm leaning towards my use of 
xscreensaver (I like the 'flurry' screensaver) as the likely culprit, 
but I had enough clutter that it's not really practical (not to mention 
that I really can't take the time) to fully troubleshoot and be close to 
100% sure.

Since I did have some clutter to deal with, and the drives (250GB mSATA 
SSD and 1TB HGST 7K1000) are two years old at this point, I decided it 
was time to refresh my installation.  So I got a good deal on a Samsung 
860 EVO 500GB mSATA and another HGST 7K1000 (one of the best 2.5 inch 
drives out there), and waited until they came in to do a complete 
reinstall, and am rsyncing files over from the older 1TB drive as 
needed.  The Dell Precision M6700 laptop has two 2.5 inch bays plus the 
mSATA slot, so I downloaded the 1804 DVD iso (mirrors must be syncing; 
the download took way longer than it should have!), installed to the 860 
SSD with the 1TB as /home (leaving the old 1TB /home alone), and 
successfully updated with CR afterwards.  The install of the ELrepo 
nvidia driver went smoothly, and after some install work and rsync work 
I'm back operational; a USB 3.0 enclosure for the older mSATA boot drive 
made it much easier.

I spent more time trying to troubleshoot GNOME3's startup than it took 
to install and update!

In a related vein, does anyone have a pointer to a good solid GNOME3 
startup document that gives enough detail to where someone can actually 
troubleshoot without having to patch and rebuild gjs and stack trace 
javascript?  Just a simple startup log woul be nice, instead of the 
SIGSEGV in /var/log/messages.....  (side note: I really hate how the 
Android GMail messes up threading; the Samsung email app is better, but 
it can't properly display a lot of the messages in the CentOS list (such 
as Johnny's) and GMail can)
