# inittab is only used by upstart for the default runlevel.

# ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.

# System initialization is started by /etc/init/rcS.conf

# Individual runlevels are started by /etc/init/rc.conf

# Ctrl-Alt-Delete is handled by /etc/init/control-alt-delete.conf

# Terminal gettys are handled by /etc/init/tty.conf and /etc/init/serial.conf,

# with configuration in /etc/sysconfig/init.

# For information on how to write upstart event handlers, or how

# upstart works, see init(5), init(8), and initctl(8).    

# Default runlevel. The runlevels used are:

#   0 - halt (Do NOT set initdefault to this)

#   1 - Single user mode

#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)

#   3 - Full multiuser mode

#   4 - unused

#   5 - X11

#   6 - reboot (Do NOT set initdefault to this)

#

id:5:initdefault:

Copy after login

Change the last line id:5:initdefault: to id:3:initdefault: to enter the command line interface by default when booting.

After restarting and entering the command line, execute startx to enter the system graphical interface!
