我在 Ubuntu 22.04.2 LTS (Jammy Jellyfish) 中使用内置的 Gnome 远程桌面和 Wayland，并使用 Windows 11 的远程桌面连接进行远程操作。出于某种原因，退出后第一次尝试连接到 Gnome 远程桌面时，我收到一条错误消息：“远程桌面找不到计算机 [服务器]。这可能意味着 [服务器] 不属于指定的网络。请验证您尝试连接的计算机名称和域。”
奇怪的是，当我“确定”错误并再次单击“连接”时，它总是立即起作用并且不会发生任何错误。
下面是每次发生的问题的视觉 gif 表示，您可以通过单击远程桌面连接中的“x”来重新创建它，重新连接并收到错误，单击确定，并立即能够重新连接到服务器： https://imgur.com/OyW66kK
我尝试journalctl --user-unit gnome-remote-desktop.service --no-pager提取一些错误日志并得出了一些结论。
- 当我点击远程桌面中的关闭按钮时，发生了一系列错误，导致连接传输失败。

我假设在最初关闭连接时，通过单击 Windows 远程桌面连接中的“x”，它要么发送一个某处的 tpkt 标头不正确或者是由于某种原因无法关闭连接，导致 3389 端口保持占用状态，直到另一个连接请求（失败）刷新/断开有问题的连接，从而允许第二次连接尝试通过？
是否有其他人知道此问题、知道解决方法，或者对从哪里开始排除故障以进行修复有任何想法？
答案1
好吧，找到了解决方案，但不是确切的原因。在 wifi 连接上运行 Linux 计算机似乎是问题所在，通过以太网插入它完全解决了这个问题。这似乎与 wifi 驱动程序/设置/配置有关，要么重置，要么每次连接后都需要唤醒。在以太网连接上，这个问题已经修复。
