我已经使用本指南或多或少地设置了 Tiger-VNC：
https://www.linode.com/docs/guides/centos-install-and-configure-vnc-server/
我面临的问题是，当我启用以下功能时，我无法保持会话启动：
sudo systemctl start vncserver@:6001.service
它立即在systemctl状态中显示“active”，然后更改为inactive dead，退出：
$ sudo systemctl status vncserver@:6001.service
○ vncserver@:6001.service - Remote desktop service (VNC)
Loaded: loaded (/usr/lib/systemd/system/[email protected]; enabled; vendor preset: disabled)

当我查看 Journal-ctl 时，我看到：

检查了这台服务器 Centos Stream 9，它似乎正在使用 Wayland。我不确定是否熟悉 Wayland，但我知道它应该取代 X。所以我猜我的问题与此有关，至于为什么它会说上面的错误（就像我假设某处有一个选项）我缺少启用 Wayland 支持，要么是这样，要么就是不兼容）。我实际上不确定该怎么做才能让它发挥作用，有人可以建议吗？

我遇到了同样的错误，这是因为 /etc/tigervnc/vncserver.users 中配置的用户已使用图形会话登录到服务器。文档 /usr/share/doc/tigervnc/HOWTO.md 的末尾巧妙地注明了这一点。
