How to enter the graphical interface when booting Linux

Edit the /etc/inittab file

# 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)

It defines the init action level executed after Linux enters the system. There are 6 levels:

Level 0, suspend and shutdown mode;

level 1. Single-user mode;

Level 2, multi-user mode, but no network function;

Level 3, full-featured single-user mode;

Level 4, no Use;

Level 5, X11 mode, which is the graphical interface mode;

Level 6, restart mode.

Change the original "3" to "5", and then reboot the system.
