Ctrl-Alt-FX doesnt work..

Hi ho..

hoping to find an answer here I have troubles with my acer aspire 1613 ..

Just as mentioned in the subject my notebook doesnt react on any Ctrl-Alt-FX- buttons. Just if I press Ctrl-Alt-F7 the screen goes black and the only thing I can see is a cursor. Unfortunately I cant go back to my KDE or just use Ctrl-Alt-F1 to a shell. All other Ctrl-Alt-F buttons dont do anything. Really strange imho... :-/

I'll be happy if someone here can give me a hint. Maybe the wrong x-server?? Just using vesa which is perfectly for me, 1400x1050 @ 60Hz.

Ah, nearly forgot. Its the latest 3.3-version installed to HD. Booting from CD doesn't change anything.

Thx, Wonko. :?
