My "basic problem" with vt is that it seems to be unable to do what
sc could do for decades, but wants to be its successor. It can even
_start_ in 80x25, but after starting X, I cannot get this mode back,
whereas sc simply shows the previous X screen content and leaves me
in "blind mode".

Because even a 1280x800 screen might be very small if the pixels
are very tightly packed. :-)
The "I want" from _my_ point of view simply is that my eyes aren't
the best ones anymore, and on Linux, I have a problem with small
fonts on small screens (usually found on laptops). I could also
imagine that people using a Braille readout (the _haptic_ inter-
face!) could face problems when they are using their 80 charcter
wide readout (with variable Y positition slider) and suddenly
can't "see" things after FreeBSD booting...
And imagine the fun of displays with much higher resolution! ;-)
There are also text mode programs that look terrible when sized
bigger than 80x25 (no matter if in xterm or on "bare metal").

Interesting approach, I will definitely try this as soon as I get
back to that particular FreeBSD 10 laptop (10.3 i386 at the moment,
waiting for 11.0-RELEASE).

I'd like it much more if it could do what sc could do for decades,
as mentioned initially. ;-)
Many thanks for the inspiration. Maybe it's possible to somehow
get the "default behaviour" back if wanted / needed.
Happy FreeBSD user since 4.0
