xrdp 从 Windows10/Centos 连接到 Centos7 后立即断开连接

这是我的 xrdp 配置：

我正在尝试使用 mstsc 连接到这台机器（这是在全新的电脑重启之后，没有人登录）：

在此登录框中，不会发生断开连接：

在我输入正确的登录名/密码后，我先黑屏，然后 mstsc 窗口关闭。我试图从 KDE 远程连接应用程序连接，但它也以同样的方式失败。xrdp.log 似乎不包含任何有趣的内容：

我该如何解决？

Answer 1

尝试这个：

停止 xrdp sudo service xrdp stop

编辑 xrdp 启动脚本： sudo nano /etc/xrdp/startwm.sh

在此文件中，替换行

test -x /etc/X11/Xsession && exec /etc/X11/Xsession
exec /bin/sh /etc/X11/Xsession

和 startxfce4

（您可以通过#在开头添加来注释掉行）

重新启动 xrdp sudo service xrdp start

选择 Xrdp 作为会话，然后登录。

Answer 2

我自己解决了这个问题，希望其他人会发现它有用。我看了一下 ~/.xsession-errors，它包含：

(imsettings-check:16467): IMSettings-WARNING **: 04:42:56.491: Could not connect: Connection refused

(imsettings-check:16467): GLib-GIO-CRITICAL **: 04:42:56.491: g_dbus_proxy_call_sync_internal: assertion 'G_IS_DBUS_PROXY (proxy)' failed
GLib-GIO-Message: 04:42:56.807: Using the 'memory' GSettings backend.  Your settings will not be saved or shared with other applications.

** (process:16260): WARNING **: 04:42:56.824: Could not make bus activated clients aware of XDG_CURRENT_DESKTOP=GNOME environment variable: Could not connect: Connection refused

然后我用谷歌搜索了一个根本原因，miniconda 安装破坏了 .bashrc 文件中的 PATH，我删除了这一行并修复了它：

    export PATH="/home/stiv/miniconda3/bin:$PATH"

更新：后来我发现x2go，它的工作方式比 XRDP 更可靠、更快。

Answer 3

1. sudo apt-get update

2. sudo apt install xrdp

3. sudo apt-get install xserver-xorg-core

4. sudo apt-get install xorgxrdp

5. nano /etc/polkit-1/localauthority.conf.d/02-allow-colord.conf

6. 将下面的 polkit 复制到02-allow-colord.conf

polkit.addRule(function(action, subject) {
if ((action.id == "org.freedesktop.color-manager.create-device" || action.id == "org.freedesktop.color-manager.create-profile" || action.id == "org.freedesktop.color-manager.delete-device" || action.id == "org.freedesktop.color-manager.delete-profile" || action.id == "org.freedesktop.color-manager.modify-device" || action.id == "org.freedesktop.color-manager.modify-profile") && subject.isInGroup("{group}"))
{
return polkit.Result.YES;
}
});

7. sudo ufw allow 3389/tcp

8. sudo /etc/init.d/xrdp restart

9. sudo systemctl status xrdp

10. sudo systemctl enable xrdp

11. 退出您的会话。

12. 尝试使用 RDP
