Removing some virtual consoles or reducing TTY is very easy.
Just follow the procedure below:
- sudo -s
- vi /etc/default/console-setup
- change ACTIVE_CONSOLES=”/dev/tty[1-6]” to your choice. Lets say if you want only two TTY or virtual console then change to ACTIVE_CONSOLES=”/dev/tty[1-2]”
- cd /etc/event.d
- Comment on all the lines in ttyx file that you don't need. In this example tty3-tty6
Reboot to see the change.
