Graphics and the FreeBSD system were not working for me quite properly yet,
also it seemed first DRI3 works OK, it does not in the mid-term, but it will
produce some kernel-panics from the irect-rendering-manager, so in fact you
have to revert the DRI-default to DRI2 by saying you don't have use for DRI3
(yet).
There were also som IRQ-18 throttling faults, probably dur to overheating,
so some measure were taken:
* integrated graphics disabled in the BIOS instead of 'auto' setting
* unused sound-card removed from the system
* DRI3 disabled in xorg.conf
* more airflow created by opening up some more expansion slots at the bottom
of the case
Final conclusion
The FreeBSD desktop is not recommended for beginners, since graphics provide
too many complications. Only try this if you have some good experience in
xorg configuration for different hardware setups from Linux, otherwise you
will soon be frustrated und be giving up.
One last word on the x11-graphics mailing list: this is not even publishing my
posts anymore, only the almighty god of nuclear power knows, whether they
have been DDoS'ed, whether there are no screenshots allowed to be sent to
the list, or why my posts are just dropped silently by now, bad
communication is generally sad. The message-size limit of 200 KB can also be
problematic, if you are not used to it.

While GNOME desktop always continued to issue, it was running on llvmpipe,
Hugin was not properly workable without DRI2 on aruba processor graphics.
Now, with the passively cooled CAICOS card from the other PC ( which has
a newer amdgpu-APU and more RAM, too, will probably profit mor from a
software-upgrade with newer driver ), there is also DRI3 support enabled
and Hugin does work properly, and there is one GB of dedicated
graphics-memory added, seems my problem is solved.

GNOME3 desktop seems OK now, but with one screen only, this means the second
screen may not even be connected even if it is not powered on, because you
will not have proper graphics-output on the digital screen otherwise, either
with some distortions and pixel-mud or no graphics output at all, upon
logging out again from the desktop-session for instance.
So in comparison with Debian there is some lack of flexibility on FreeBSD,
and it is easy to tell, that Linux is generally more suitable for mobile
devices like laptops and more beginner-friendly.

While technically my old A6-APU has AMD processor-graphics (which would
suggest amdgpu), RADEON is the correct driver here, since this is not new
enough.

OK, how you have the newest latest hardware and how you are getting free
publicity and enormous marketing-capacities without any costs from these
technical mailing lists is not exactly my concern, since if it was, then I
would not not be working on pretty much the oldest productive PC around here,
right?? And NVidia is also very very interesting (for some people), I am
sure about that.

OK, well it seems I am 80% fine now with the radeon-driver, I have checked and
it is also in use on my main desktop PC with an older (CAICOS) graphics card.
But radeon could still need some configuration tuning, because the picture
appears a bit snowy on the larger digital screen, which wasn't the case with
Debian-oldstable, which became old-oldstable recently, time to upgrade soon.

Seems OK now finally, without using AMDGPU-driver from ports,
this was also a good read:
> https://en.wikipedia.org/wiki/Direct_Rendering_Infrastructure
You see I changed to FreeBSD12, because installing TrueOS (and disabling
boot) turned out an 'unrepeatable error'.
This seems mostly identical, also gave me ZFS-root and many more options
during install-time, probably I could also use open-RC here, but that is not
even necessary, so it does not really matter which one you love the most.
