hi every body

I have recently install on hard disk knopixx 3.2
I worked fine, but the changing to other screen ( screen text F1 to F6) does not work, and the computer
stops working ( nothing works you have to get down th PC)


the getty program is running
ps aux gives for example
root 299 0.0 0.3 1480 400 tty3 S Feb25 0:00 /sbin/getty 38400 tty3


thank you for help
