(In reply to Chris Hutchinson from comment #5)

Are you 100% sure all your hardwares are legacy (non-UEFI) booted?
On UEFI, efifb (only usable via vt) is forced and sc is not emulated (by
firmware) at all.
So nothing can detect legacy (character based) frame buffer on UEFI-booted
environment. (For UEFI-capable hardwares with legacy boot ennbled, CSM of U=
EFI
firmware would take care of it, just stop hiding physical text frame buffer=
 or
emulate actually-nonexistent hardware, which would be dependent on hardware=
).

It's a limitation of UEFI, not of FreeBSD. So kern.vty=3Dsc on UEFI-booted
environment would be ignored and forced vt.

On vidcontrol side, discussions would be needed which to capture, graphical
frame buffer or vt-internal text buffer.
Someone would want images displayed to be captured, that means, texts are a=
lso
captured as image, not as characters.

But OTOH, others would want only texts to be captured as characters.
This is like the behaviour with mice driven by moused.
