ubuntu gedit出错:Failed to connect to the session manager

刚才用su到root后，用命令gedit发现会出错：** (gedit:2976): WARNING **: 连接已关闭(gedit:2976): EggSMClient-WARNING **: Failed to connect to the session manager:None of the authentication protocols specified are supported** (gedit:2976): WAR

刚才用su到root后，用命令gedit发现会出错： ** (gedit:2976): WARNING **: 连接已关闭 (gedit:2976): EggSMClient-WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supported ** (gedit:2976): WARNING **: Could not connect to session bus

原因是： su 只能切换到管理员用户权限,不使用管理员的登陆脚本和搜索路径

su - 不但能切换到管理员权限而且使用管理员登陆脚本和搜索路径
解决方法：使用sudo gedit 或者su -后再gedit就没错误了！
