Nah. Senior moment. elrepo, of course :)

Ah. thanks for that info. I have to admit I don't know what ocl-icd
is for, nor why I have it. [later...] Ah. Something to do with OpenCL.
Not sure what I need it for, now (unless Firefox or Chrome--or Vivaldi
might use it). I used to run Folding At Home, but don't anymore. I think I
saw a reference to wine in one posting too but don't run wine on this box.

Anything else that might break if I remove that? (or are you implying
that the nnvidia packages install a suitable substitute for it?)

I'll be trying this in a few days. I need a better way of doing a bare-
metal backup before I try it again, so the 4 TB usb drive I just ordered
should do the trick once it arrives. (this last try I backed up 
everything onto my NAS box, which took ALL DAY plus several more hours
to run md5sum on the dd image files. yes, I know md5 is deprecated.)

So, once I get that and get everything backed up again I"ll give your
suggestions a try and post here what happens.

thanks again for your guidance!
