感觉就像 RDP 连接到我的 Ubuntu 机器取决于天气、星星或月亮。有时它有效，有时无效。我尝试了在网上指南中找到的各种修复方法，包括：
- 从 ppa:martinx/xrdp-hwe-18.04 使用 RDP
- 运行 echo "gnome-session --session=ubuntu-2d" > .xsession
- 连接到 X11 RDP 会话，然后连接到正常 RDP 会话
- 将 RDP 添加到 ssl-cert 组
我已经清除了 RDP，重新安装，然后再次清除——但没有成功。
没有真正的错误消息 - 只是出现了问题并且它就在那里。
这是我在 Windows RDP 客户端中收到的错误消息：
以下是日志 xrdp.log 的输出：

答案1
再次，只是一个想法...也许你必须检查以下配置文件
/etc/X11/Xwrapper.config
并确保线路
允许用户=控制台
更改为允许的用户=任何人
日志中的错误可能表明只有控制台用户才能连接到 X 服务器
以下链接可能有助于调试您的问题

希望这能有所帮助，下次见
答案2
sudo apt install xserver-xorg-core
sudo apt install xorgxrdp
适用于 18.04.2 LTS。欢迎您。
