Nope. Or rather, you could, but it wouldn't do what you expect  ;-)

Ubuntu uses the Debian model, and the default runlevel is 2, unless
otherwise configured - so init 3 won't help, I'm afraid, unless you
enjoy reconfiguring runlevels .

If you have the file /etc/X11/default-display-manager  you can edit it or
do

echo "false" | sudo tee /etc/X11/default-display/manager

This will disable gdm/kdm/xdm , or whatever you have in that file

You can put it back with a text editor, or do for example

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

Of course, for a temporary disabling of X you can just do

sudo /etc/init.d/gdm stop        then use the "restart" option or the
"start" option of that init.d script  to restart it.
