I got this error too, over a ssh connection. vidcontrol worked fine when I
tried it from the physical console. This was after rebuilding the kernel

I guess I would say hold off until you have physical access, because it makes
no difference unless you are sitting in front. Perhaps it works over serial?
I am not sure.

Yes. Plus it just looks nicer, for lack of a better term.

Can't speak to this issue technically, but it essentially allows you to use
much smaller, yet readable fonts in the console.
