Disable GUI on Solaris

After installing Solaris 10 on my Virtualbox, I would like to turn off the Graphical User Interface aka GUI since I won't be using it. To turn off the GUI, I use smf.

# svcadm disable cde-login

After doing it, I rebooted solaris and I don't see anymore GUI.

# svcs cde-login
STATE          STIME    FMRI
disabled       16:17:51 svc:/application/graphical-login/cde-login:default
