Open/create the file /etc/X11/xorg.conf using the following command:

sudo -i gedit /etc/X11/xorg.conf

and add the following lines inside:

Section "ServerFlags"
    Option "DontVTSwitch" "true"
EndSection

Answer 2

I found three methods. I'm listing to help others if they need:

First Method:

sudo tee -a /etc/init/tty{1..6}.override <<<"manual"

Second Method:

Open/create the file /etc/X11/xorg.conf using the following command:

sudo -i gedit /etc/X11/xorg.conf

and add the following lines inside:

Section "ServerFlags"
    Option "DontVTSwitch" "true"
EndSection

Third Method:

sudo -i

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.

Answer 3

sudo rm /etc/init/tty*.conf

This will totally remove the tty* conf file and thus you will not be able to use it :)

NB: you can't be able to restore it later on

Answer 4

open the tty conf in the /etc/init/ directory

comment out those lines in the ttyX.conf files:

#respawn 
#exec /sbin/getty -8 38400 ttyX

Example to disable tty1:

sudo -H gedit /etc/init/tty1.conf

Then edit by inserting # in front of the commands

#respawn 
#exec /sbin/getty -8 38400 tty1

Save and Reboot
