Howto Boot debian in text mode instead of graphical mode (GUI)

You can prevent automatic running of the GUI when you boot your
debian machine by disabling your login manager be it KDM, GDM or
XDM from running at boot time. To disable the login manager from
automatically running at boot up, run the following command as root

#update-rc.d -f gdm remove

Replace gdm with kdm or xdm if they are what you use.

To start X manually, you would then have to login at the command
prompt and enter the command startx.

To reset your login manager so that it runs at boot up, do

#update-rc.d -f gdm defaults
