Why installation done by cobbler from Red Hat Satellite by default executed in text mode? Is text parameter hardcoded?

Issue

• Created one kickstart profile and added the parameter graphical into the same as installation was required to carry out in Graphical mode instead of text mode.
• When the installation was carried out through cobbler, it is executing into the text mode although the parameter graphical is provided into the kickstart profile.
• Why the installation is carried out in text mode? Is it hard-coded somewhere?
