2.配置系统为图形模式，打开/etc/inittab，修改为id:5:initdefault: (若已为5则不需修改)

vi /etc/inittab

3.打开/etc/gdm/custom.conf，在[security]和[xdmcp]字段下分别添加如下内容：

[security]
AllowRemoteRoot=true
[xdmcp]
Port=177
Enable=1

4.关闭防火墙(service iptables stop)或在防火墙上打开udp 协议177 端口。默认是关闭的。

[[email protected] gdm]# /etc/init.d/iptables status
iptables: Firewall is not running.

5.重启机器
