作为一个个人项目，我决定开始在虚拟机上构建 Linux From Scratch（System V 版本，9.1）。一切都很正常，直到通过 LightDM 进入系统的那一刻。输入用户名和密码后，屏幕上出现一条消息，提示连接被拒绝。我尝试查找有关该问题的信息，但没有任何帮助。我也尝试使用LXDM，但发生了同样的问题。
这是出现的消息：
（翻译：无法与配置服务器连接 - 无法连接：连接被拒绝）
我可以通过运行 startx 和 startxfce4 进入 XFCE。但是，当我尝试输入 xfce4-session 或 xfsettingsd 命令时，屏幕上出现相同的错误：
Unable to init server: No se pudo conectar: Conexión rehusada
（翻译：无法连接：连接被拒绝）
如果需要更多信息，请告诉我。
这是 Xorg.0.log 的内容：
