可能之前已经回答过这个问题了，但是我还没能找到它。
环境信息：
- 通过 WSL2 运行 Ubuntu 20.04.1 LTS
- Windows 10（2004、19041.508）
- 全面升级
- 网络连接到位
- 已安装 xrdp 和 mate-desktop
问题 当我连接到 127.0.0.1:xrdp_port 时，会出现登录屏幕，如下所示： 登录屏幕。我在 xrdp 配置中添加了用户名，这样我就不必总是费心输入我的登录用户。问题是，当在登录屏幕中按“确定”时，连接断开而没有任何消息。

我希望你能知道我这边出了什么问题。
答案1
现在我已经通过安装 mate-core 自己解决了这个问题。
