我在ubuntu机器上的显示器：1上启动了一个vncserver。连接到它时，我得到一个带有错误消息的灰色X窗口Could not connect to session bus: Failed to connect to socket。
vnc日志是：

任何想法如何解决？
我想知道是否是由于这一部分：错误打开安全策略文件/ etc / X11 / xserver / SecurityPolicy ...某些权限问题，它需要访问该目录，但不允许访问？否则，我遇到的每个vnc问题都是因为A：我忘记转发端口或在路由器上启用DMZ B：我忘记将服务器和查看器都设置为指定的端口（在您的情况下为5901）... C：我得到了错误的IP信息（例如，如果您连接到无线网络，并且VNC服务器在同一网络上运行，则使用的是网络IP地址，而不是外部IP。）

DBus在这里搞砸了。重新安装它，然后再试一次。
