RHEL 8.1 - Tiger vnc 连接后显示黑屏

Question

我已按照下面链接中显示的说明在 Red Hat 8 Enterprise 服务器上安装 TigerVNC。

https://www.howtoing.com/install-and-configure-vnc-server-in-centos-7/

但是，当我从 Windows vnc 客户端连接到服务器时，我只看到黑色显示屏，并且只有鼠标指针在工作。这似乎是一个相当普遍的问题，但到目前为止我在谷歌上搜索的所有内容似乎都没有帮助/适用。

日志文件中有一条错误消息可能是问题所在：

导入环境失败：进程 org.freedesktop.systemd1 已退出，状态为 1

这是整个日志文件：
