cp /etc/inittab /etc/inittab.bk
nano /etc/inittab

# Default runlevel. The runlevels used by RHS 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 <--------TEXT MODE
#   4 - unused
#   5 - X11                 <--------GRAPHIC MODE
#   6 - reboot (Do NOT set initdefault to this)
#
#id:5:initdefault:
id:3:initdefault:

Sau khi cài graphic xong bạn muốn cho nó khởi động thì chỉ vào text thi bạn edit lại /etc/inittab từ default 5 thành 3
