I'm not quite clear whether you mean that you have both ubuntu-desktop and
kubuntu-desktop installed. If you do, there should be (at least on Dapper
6.06) a file "/etc/X11/default-display-manager"

If you have kdm running by default it will contain  /usr/bin/kdm . If
you change this to /usr/sbin/gdm , then gdm will start instead of kdm. A
quick way to change it is to type in a terminal

echo "/usr/sbin/gdm" | sudo tee /etc/X11/default-display-manager 

I seem to recall you can achieve the same thing by running 

sudo dpkg-reconfigure gdm  or kdm 

- but I can never remember which one ;-)
You could try that way if you wish. Of course, if you want gdm and it is
not yet  installed, you need to install it first ... but that's obvious I
suppose !
