CentOS 6.5 GDM 非root用户自动登陆-摩杜云开发者社区

我的测试平台为：

CentOS 6.5 x86 32位桌面版（GDM）

[root@localhost ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m

从百度中搜到的都是修改/etc/gdm/custom.conf文件，如果你按照百度搜到的去修改（/etc/gdm/custom.conf）的话，重新启动后，普通用户并不能实现自动登陆。

经我测试及查看代码发现，CentOS 6.5 并非修改此文件，而是修改/etc/gdm/gdm.schemas 这个文件。

我的修改此文件，将普通用户leekwen实现自动登陆，修改后与修改前的对比做出了patch文件。

参见patch代码：
