vmplayer中的fedora20无法进入图形界面

           新装了台fedora20的虚拟机，安装升级了一些东西后。启动时过了fedora的logo画面后就是黑屏。

也没提示不论什么错误，好在shell还能进去。查看/var/log/anaconda/syslog日志，发现错误例如以下：

这些是SELINUX的安全检查，内核在运行系统调用前会询问 SELinux 进程是否获得了运行操作的授权。

解决的办法也非常easy，就是对对应的进程进行授权，或是关闭SELINUX，这里。我选择后者，改动文件/etc/selinux/config，将当中的

SELINUX=enforcing

SELINUX=disabled
