正确的凭据后 XRDP 立即断开连接

Question

我面临 XRDP 的问题，在输入正确的用户名密码后，会话立即终止。我在论坛上看到了很多该问题的发生，但没有一个解决方案有帮助。您能建议一些后续步骤吗？

这是 xrdp.log

我已经尝试过以下方法：

• 防火墙允许端口 3389
• xfce4-session我在 /etc/.xsession 上添加了以下内容 ->
• 我还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

• 安装的 TigerVNC 软件包
• 然sudo adduser xrdp ssl-cert
• 每一步都重新启动服务

尽管如此，我还是无法让 XRDP 工作。

Answer 1

根据您对问题的描述，这可能是由于您已经登录 Ubuntu 并且您正在尝试使用相同的用户帐户进行远程桌面连接。

不可能（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您的 Ubuntu 计算机上......

希望这会有所帮助，下次见

Answer 2

为了将来的参考，我遇到了同样的问题，并且没有深入了解为什么会发生这种情况，我只是安装了另一个桌面环境（xfce4）并且工作正常。看来是 GNOME 的问题。

安装：

sudo apt install xfce4

然后切换到它：

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