在su用户模式下使用nautilus打开当前文件夹失败

[root@localhost hello]# nautilus ./

(nautilus:4038): EggSMClient-WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supported

(nautilus:4038): Eel-WARNING **: GConf error:

Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection
to session: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)

解决方法：

就是在管理员用户的 .bashrc 文件尾部添加：

export DBUS_SESSION_BUS_ADDRESS=""

例如，编辑 ／root/.bashrc 文件，添加一行 export DBUS_SESSION_BUS_ADDRESS=“”

另外就是使用 su - root 代替su，sudo

其区别是su sudo 使用当前用户的环境变量，su - root会使用root用户的环境变量。
