how to change default X teminal to tty9 ,etc ?

["cwinl" <cwinl-debian-user@lnnu.edu.cn>]

hi all,

i used to install debian in chroot.
someone tell me that i should turn the chroot default X terminal to tty9 against original tty7.
i had watched chroot debian's /etc/gdm/gdm.conf file,but cant found the vt7 and so on.
i changed 'irstVT=7' to 'FirstVT=9' but it doesn't work.
X terminal is always tty7.
i'm confused how to finish it.

thanks.
