Addendum:

When I set view full screen, it goes to full screen, but the VM
display is the default small box in the center.  When I unset full
screen, it shrinks to that smaller size, which I can then expand to
fill the whole screen (with the VM window edges and title bar).

The Ubuntu VM never came up with any display, so I gave up.  I removed
it and will reinstall from scratch.  I'll let all know what
transpires, if it's interesting at all.

Thanks again.
