gnome-remote-desktop 无法启动 RDP 服务器：绑定到地址 [::]:3389 时出错：地址已在使用中

我正在尝试寻找答案，但目前还没有找到。我安装了 Ubuntu 22.0.4，但 Gnome Desktop 无法工作，因此我继续升级到 23.0.4，希望它能解决以下问题，但并没有。它在 Windows 11 和 Mac 上不起作用。Gnome Desktop 显示以下错误：

yigal@yigal-desktop:~$

当 RDP 客户端启动时，它会挂起并保持黑屏。重新启动 gnome-remote-desktop 并重新启动 Ubuntu 不会出现这种情况。

我不精通 Linux，但我怀疑它与 libnvidia-encode 有关，因为：

May 07 23:49:37 yigal-desktop gnome-remote-desktop-daemon[9559]: Cannot load libnvidia-encode.so.1

有人能帮我解决这个问题吗？

答案1

无法加载 libnvidia-encode.so.1

这无关紧要。gnome-remote-desktop 支持 NVENC 和 CUDA。如果它们不可用（例如由于未使用 NVIDIA 卡），那也不是问题，因为软件编码有后备方案。

您的问题是其他进程已绑定到 RDP 端口 (3389)。TCP 端口只能绑定一次。
因此，需要做的是关闭占用 3389 端口的程序或进程。

你可以使用 查看哪个进程占用了端口ss -ntlp。然后终止在 3389 端口上运行的进程（ss -ntlp终止后可以通过 检查是否成功），然后通过 重新启动 gnome-remote-desktop systemctl --user restart gnome-remote-desktop。

但需要注意的是，已经占用 3389 端口的进程可能会自动运行，例如通过另一个 systemd 单元。
根据进程的不同，您可能需要完全禁用它。否则，每次重新启动系统时，您都会再次遇到同样的问题。

答案3

对我来说，ss -ntlp没有显示使用端口 3389 的进程。但卸载 XRDP 并重新启动后，Ubuntu RDP 服务就可以正常工作。
