Turns out that all I had to do was:

sudo apt-get install xfonts-100dpi
sudo-apt-get install xfonts-75dpi

I'd had to do something like this on my old Fedora-running laptop. 
Finally figured out the apt-get command analogous to the old yum 
command.  (Different package name(s); took me a while to find/figure out 
what the appropriate names are.  I'm *slow*!!!)

Thanks to everyone who tried to help me overcome my stupidity!

cheers,

Rolf Turner
