Yes.

Where would the people maintaining the video driver have to look?

Yes.

Interesting. I'll try that.

May this be a problem of the fb driver then?

Thanks for your input,

Update: This makes no difference for me.

Exactly the same behaviour.

None of the keys make any difference.

Try hitting the hardware function key that swaps the CRT/LCD and/or the
function key that changes the font.

Works on my laptop. Really annoying two-fold issue. First, the screen
is blank, second, I have to blindly run setfont to change the garbage
font to a readable font.

I'm not running an fb, just an nvidia card in text mode on a Dell
Inspiron 8200.
