First of all, why run konqueror as root? The root user should only be
used to do specific admin tasks that can't be done as any other user.
Use it as little and as sparingly as possible.
To actually answer your question though, look at the xhost manpage. You
can use that command to control who can connect to the X server.
in my .xsession which allows all users from localhost to open windows on
my X server.
