Ubuntu Mate 16.04 上的 xRDP - 连接错误

772

在戴尔 Optiplex 780 上全新安装和更新 Ubuntu Mate 16.04。

从 Windows 10 客户端连接。

之后直接安装 xRDP 并尝试从 Windows 连接。

进入 RDP 会话并输入凭据。然后...

得到这个错误。

Connecting to sesman IP 127.0.0.1 port 3350
sesman connect ok

srdp_mm_process_login_response:login successful for display

connecting to 127.0.0.1 5910
error-problem connecting

运行此命令

:~$ sudo netstat -peant | grep "127.0.0.1"

并得到：

tcp        0      0 127.0.0.1:3350          0.0.0.0:*              LISTEN      0          39396       8082/xrdp-sesman

用grepping“5910”尝试了同样的方法，它什么也没返回。

尝试删除 xrdp，然后先安装tightvncserver，创建vnc 桌面连接，然后安装xRDP，因为这是我之前在其他计算机上设置的方式；

我在其他计算机上使用 VNC，然后发现了 xRDP，然后安装了 xDRP，杀死了 :1 桌面并且能够毫无障碍地使用 xRDP。

在这个桌面上，根据 systemctl 检查的结果，xRDP 服务运行良好。

尝试连接然后查看我的 /var/log/syslog ，结果如下：

从这个帖子中得到了一些想法，

连接错误/问题（Windows 10 RDP 到 XRDP）

其中引用了这个...

https://ubuntuforums.org/showthread.php?t=1314336

但是，没有骰子。

我应该在 Mate 中做一些不同的事情吗？

我应该在另一个线程中发布这个吗？

帮帮我，Ubuntu Mates！

更新！

没有改变任何东西，但重新启动。第一次遇到同样的错误，但后来...

现在我可以从 xRDP 登录提示完全登录，而不会出现以前的错误，但会看到这个灰色的像素化屏幕。

/var/log/syslog 看起来像......

哇！比我想象的要容易得多。我只是使用了这个简单的 xstartup 指令和繁荣，低 cpu 使用率和良好的连接。

#!/bin/bash
xrdb $HOME/.Xresources
startmate &

我显然想多了，没有正确进行设置。

现在我知道：

安装紧密的vnc
启动 :1 桌面然后杀死以创建 ~/.vnc 目录和配置
确保 xstartup 指令是上面的超级基本 3 行，并在必要时覆盖。
安装 xrdp
再次启动 :1 桌面
使用我最喜欢的 RDP 客户端 Remmina 进行连接！
尝试新的东西，犯错误，问你关于它的问题，排除故障，并以某种方式让它工作，以了解更多关于“Nix 是如何工作的！

谢谢，Ubuntu 伙伴！
