当使用我设置机器的用户时，我无法通过 xrdp 连接。
我在我的 2012 mac mini 上安装了桌面版 Ubuntu 22.04。目标是将其用作无头服务器并专门远程连接到它（即从本地网络上的另一台计算机）。
我在安装 Ubuntu 时创建了第一个用户。我安装了xrdp。然后我移除了鼠标、键盘和显示器。使用 Mobaxterm，我可以使用第一个用户或我创建的虚拟用户通过 ssh 进入盒子。
我无法通过 rdp 与第一个用户连接，但是在使用虚拟用户时可以连接。这些信息足以猜测正在发生的事情吗？思考我接下来应该做什么？
编辑：
/etc/xrdp/startwm.sh每个@thing添加的内容- 我意识到我正在尝试让鳄梨酱运行。我卸载它看看是否有问题。
- RDP 正在与安装 Ubuntu 的用户合作。我相信这是因为我更新了 Ubuntu，但我不能确定。
获取默认值
systemctl get-default给出“图形.目标”。我尝试设置为 multi-user.target 但没有效果。
使用用户“GOOD_USER”成功进行 rdp 连接
