Linux 系统更改界面显示详解

1,修改配置文件

# 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:

最后一default为默认配置项。 

2，通过systemctl 修改开机启动模式

#a,查看当前启动模式
systemctl get-default

#b,修改启动界面为图形界面
systemctl set-default   graphical.target

#c,修改启动界面为字符界面（命令行）
systemctl set-default  multi-user.target
