[newbie] Can't stop X

[Art Richardson]

Hi
        I installed Mandrake 7.0 in a dual boot machine. It installed beautifully,
almost  everything works except for my 3Com 3c509 isa PnP nic. However, what
I am trying to figure out is how I exit from KDE and just run from the bash
shell. Please tell me how to turn it off
Many thanks
Art
