我正在尝试通过 xRDP 从 Win10 连接到我最近安装的 Bodhi Linux。我可以从这个客户端连接到许多其他 Ubuntu 服务器。这是我第一次接触Bodhi，但一切看起来都很熟悉。
我该如何解决这个问题，或者至少诊断？
下面我就贴出相关信息。

对我来说，它有效（Ubuntu-20.40）将会话管理器更改为xfce4这样：
$ update-alternatives --config x-session-manager
There are 3 choices for the alternative x-session-manager (providing /usr/bin/x-session-manager).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/gnome-session 50 auto mode
1 /usr/bin/gnome-session 50 manual mode
2 /usr/bin/startxfce4 50 manual mode
3 /usr/bin/xfce4-session 40 manual mode
Press <enter> to keep the current choice[*], or type selection number: 2
update-alternatives: using /usr/bin/startxfce4 to provide /usr/bin/x-session-manager (x-session-manager) in manual mode
再次运行命令（只是为了检查）
$ sudo update-alternatives --config x-session-manager
There are 3 choices for the alternative x-session-manager (providing /usr/bin/x-session-manager).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/bin/startxfce4 50 auto mode
