问题

我在一台旧电脑上使用最近安装的 Lubuntu 20.04.3。我打算通过 xRDP 从 Ubuntu（remmina）和 Windows 10 电脑进行连接，但到目前为止，我无法从任何一台电脑进行连接。

从 Ubuntu 20.04.3 remmina 连接时看到的内容：

  1. 屏幕 1 显示消息显示 0 登录失败。
    从下面的日志中，我明白这只是一个警告，但随后尝试连接显示器 10（或显示器 11，如果已经使用显示器 10 进行 X 连接）成功。
    所以我以后只会考虑如何删除显示器 0 的初始尝试，或者如何使其成功。
  2. 屏幕 2 带有登录提示。
  3. 短暂的黑屏，然后连接窗口关闭。

在此处输入图片描述在此处输入图片描述

我怎样才能解决这个问题？

注意：我认为用户名/密码没有问题。没有特殊字符，也没有大写字母。我可以从 Ubuntu 和 Win 10 毫无问题地 ssh 到该服务器。此外，下面的日志表明这是没问题的。

我迄今为止尝试过

请参阅下文了解具体信息；这些都没有改变结果：

  1. 安装所需的软件包：xrdp xorgxrdp xserver-xorg-core xserver-xorg-input-all

  2. 已启用该服务。

  3. 添加两行/etc/xrdp/startwm.sh如图所示修复 Ubuntu 黑屏. 重新启动服务。

  4. 删除了证书问题（选项 2这里)，然后sudo adduser xrdp ssl-cert重新启动服务。再次连接后，remmina 要求我接受证书，我照做了。

  5. 编辑/etc/X11/Xwrapper.config如下这里. 重新启动服务。

  6. ~/.xorgxrdp.11.log鉴于（failed to take device: Operation not permitted）中的错误信息和这解决了类似的问题（尽管不是用 xrdp），我尝试启用 KMS（我了解到radeon这是驱动程序）

    $ sudo nano /etc/initram-tools/modules
(adding radeon at the end)
$ sudo update-initramfs -u
$ sudo shutdown -r

  7. 按照以下步骤在服务器中注销并进行远程连接这。

我不太确定有几点：

  1. 这个问题是否与我在客户端使用 Gnome，在服务器上使用另一个 WM 有关？如果是可以，我该如何确认或排除这一点？我该如何解决这个问题？见下文。
  2. 问题是否与第一次尝试使用显示器 0 有关？如果是这样，我该如何删除该初始尝试，并在第一次尝试中使用可用的显示器（10、11 等）？
  3. 如果我在家，所有 PC 都连接到同一个路由器，我需要任何 UFW 规则吗？如果需要，设置规则的命令是什么？
  4. 我应该/etc/xrdp/xrdp.ini按照图示进行修改吗这里？
  5. 下面的摘录是否~/.xsession-errors表明了下一步该尝试什么？如果是，应该遵循哪些命令？
  6. 线路是[ERROR] g_tcp_bind(9, 6010) failed bind IPv6 (errno=98) and IPv4 (errno=22)解决方案的关键吗？如果是，应该遵循哪些命令？
  7. 我可以在没有 VNC 服务器的情况下执行此操作吗？（我会尽可能降低对服务器的需求，因为它是一台旧电脑）。这和这提及 VNC 服务器作为一项要求。
