在fedora10下，运行gedit，普通用户下不会出错，但在su到root下会出现如下错误,
(gedit:12541): EggSMClient-WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supported
(gedit:12541): EggSMClient-WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supported
GConf 错误：联系配置服务器失败；某些可能原因是需要为 ORBit 启用 TCP/IP 联网，或者由于系统崩溃，您的 NFS 锁定已失效。请访问 http://www.gnome.org/projects/gconf/ 了解详细信息。(详细信息 - 1: 获取到会话的连接失败：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.)
虽然这时gedit也可以正常启动，但总感觉别扭。在网上搜索很久，终于找到两种解决办法，分享给大家：
1.用sudo，如：
sudo gedit 文件名
2.出错是在su时出现的，现在我们改用su -:
su -
gedit 文件名
ok.出错信息不再出现！
