To switch to a text console press CTRL+ALT+F1. You have six text console 
(F1 through F6). To access the graphical one hit CTRL+ALT+F7 (if X is 
just running).

As you said you can reconfigure X with

  dpkg-reconfigure xserver-xfree86

To reboot from command line:

  sudo reboot

or

  sudo poweroff

(the latter shutdown completely the computer).
