我已经按照以下步骤在 Ubuntu Server 20.04 上安装了 Xfce 和 Xrdp
$ sudo apt install xrdp
$ sudo apt install xserver-xorg-core
$ sudo apt install xserver-xorg-input-all
$ sudo apt install xorgxrdp
$ sudo adduser xrdp ssl-cert
$ sudo systemctl start xrdp
$ systemctl is-active xrdp
$ sudo systemctl enable xrdp
$ sudo reboot
重启后一切似乎都正常了，我可以毫无问题地登录我的服务器，但在我关闭 RDP 窗口后，事情似乎有点不对劲。首先，我的服务器非常强大，但重启xrdp需要 20 秒！当我登录服务器时，需要超过 15 秒才能登录服务器，并且 RDP 剪贴板不再工作。当我重启服务器时，一切都正常，但只有我第一次登录服务器时，它就变得一团糟。此外，当我重新启动时，xrdp我无法登录服务器，因为按下login按钮后窗口就消失了
我到目前为止尝试过但没有效果的方法
- 结束语程序库然后再次打开它
- 添加驱动器在 RDP 中本地设备部分
cat /var/log/xrdp.log重启 xrdp 之前的输出

更新
在 `xrdp.ini` 中禁用 `channels`，现在登录缓慢的问题已修复，但由于现在禁用了频道，剪贴板问题仍然存在allow_channels=false
答案1
我知道已经过去几个月了，但如果有人遇到：
我在这篇文章中找到了解决方案： https://askubuntu.com/a/1367195/564580
总结一下：你必须编辑文件
/etc/xrdp/xrdp.ini
向下滚动到
[频道]
并确保这两个设置为 True：
rdpdr=true
cliprdr=true
-> cliprdr (clibpoard 重定向) 和 rdpdr (驱动器重定向)
重新启动 xRDP 后，它可以正常工作，并且我可以通过剪贴板双向交换数据。
