I'm glad I took your advice.  I installed 16.04 LTS, erasing
everything else on the drive.  It automatically made  a swap partition
the size of my RAM.  I installed nothing else, ran "sudo pm-hibernate"
and it worked, perfectly.  Yes!

I also turned on hibernation in the "Log Out" menu, and it also worked
perfectly.

So I'm set -- I'm sticking with 16.04 LTS.

Thanks all.

Mike


Glad everything worked out :-)
