kpersonalizer: cannot connect to X server

[williamkow]

I am newbie, recently I have installed FreeBSD 6.2-Stable, and manage to
configure and display the x window manager (X11) using command "startx".
and then i run command "startkde " and I received error message
(kpersonalizer: cannot connect to X server)
However, if i run command "kdm", then it prompt for login screen. I am
wondering the command "startkde" is not correct way to call KDE. please
advise me. Thank you.
