正确输入凭证后 XRDP 立即断开连接

我在 XRDP 中遇到了一个问题，输入正确的用户名密码后会话立即终止。我在论坛上看到过很多次这种问题，但没有任何解决方案能起到作用。您能建议一些后续步骤吗？

这是 xrdp.log

我尝试了以下方法：

  • 防火墙允许端口 3389
  • xfce4-session我在 /etc/.xsession 上添加了以下内容
  • 我也曾尝试注释掉以下几行startwm.sh
test -x /etc/X11/Xsession && exec /etc/X11/Xsession
exec /bin/sh /etc/X11/Xsession
  • 已安装 tigervnc 软件包
  • 冉sudo adduser xrdp ssl-cert
  • 每次都重新启动服务

尽管如此，我还是无法让 XRDP 工作。

答案1

根据您对问题的描述，这可能是因为您已经登录到 Ubuntu，并且正在尝试使用相同的用户帐户建立远程桌面连接。

无法（使用 xRDP 软件）在本地 Ubuntu 上使用相同的用户帐户并同时登录并执行远程连接...

要评估这是否是问题所在，请确保执行远程连接的用户帐户尚未登录到你的 Ubuntu 机器上....

希望这能有所帮助，下次见

答案2

供以后参考，我遇到了同样的问题，没有深入研究为什么会发生这种情况，我只是安装了另一个桌面环境（xfce4），它运行良好。这似乎是 GNOME 的问题。

安装：

sudo apt install xfce4

然后切换到它：

sudo update-alternatives --config x-session-manager

答案3

我遇到了同样的问题，但我在一台 2009 年中期的旧 MacBook Pro 上运行 Ubuntu 18.04 LTS，并且我进入了“软件和更新”、“附加驱动程序”选项卡，并将默认图形驱动程序从 X.Org X 服务器更改为专有的 NVIDIA 二进制驱动程序。一旦我将其改回更普通的 X.Org X 服务器，它就允许我通过 XRDP 登录，而无需在之后断开连接。
