Just remove any login-manager like gdm, kdm, sddm and lightdm. For testing purposes, you can eaily remove the binaries below /usr/bin/ to somewhere, for example to /root/.
Then reboot and it will not boot into X. Startx will work. And if this is not what you want, just move the binaries back to /usr/bin/, reboot and X is starting at boot again. Hope this helps.
