Because when I tried just running "startx" (as per the instructions
in the current FreeBSD handbook) I got this error and X did not start:

Fatal server error:
no screens found

However I believe that I just now may have figured out what the problem
is here.

The system in question contains an AMD A4-6300 APU.  This is not exactly
a newly released APU.  Amazon lists it as having been available since
May 20, 2014.  So the thing has been out for around 7 months or more.

However the integrated GPU is apparently a Radeon HD 8370D.

Looking now on this page:

    https://wiki.freebsd.org/Graphics

it appears that perhaps Radeon HD 8xxx is not yet supported by X on
FreeBSD.  I guess that is the problem, yes?

I am bummed, to say the least.

I guess that I will have to break out the old Radeon HD 5450 card that
I have sitting and collecting dust in the closet, jam that into the
ASUS A78M-A motherboard, and then see if I can entice the BIOS into
using that in preference to the integrated GPU in the AMD A4-6300 APU.

Sigh.  I don't know how to do this, but I guess that I will find out.

Any suggestions on how to accomplish this will be appreciated.
(Obviously, it isn't just the BIOS but also FreeBSD+X that have to
be convinced to ignore the in-built GPU on the APU in preference to
a slower GPU on an add-in card.)
