我以root身份使用sudo nautilus命令时收到以下错误。 请建议一个出路

root@catherine:/home/catherine/Downloads/cmake-3.8.0-rc2# sudo nautilus (nautilus:639): Gtk-WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files ** (nautilus:639): CRITICAL **: Another desktop manager in use; desktop window won't be created Nautilus-Share-Message: Called "net usershare info" but it failed: Failed to execute child process "net" (No such file or directory) 

如果你想以root用户身份使用nautilus,你应该使用gksudo nautilus因为’gk’为sudo提供了一个图形前端,这意味着它可以用来安全地启动需要GUI的程序
