我正在尝试使用 mstsc 连接到这台机器（这是在电脑重新启动后，没有人登录）：

在此登录框中，不会发生断开连接：

输入正确的登录名/密码后，我首先出现黑屏，然后 mstsc 窗口关闭。我尝试从 KDE 远程连接应用程序进行连接，但也以同样的方式失败。 xrdp.log 似乎不包含任何有趣的内容：

我该如何解决这个问题？

答案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。

答案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根本原因，miniconda 安装破坏了 .bashrc 文件中的 PATH，我有已删除这条线已经修复了：

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

更新：后来我发现x2go，其工作方式比 XRDP 更可靠、更快速。

答案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;
}
});

  1. sudo ufw allow 3389/tcp

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

  3. sudo systemctl status xrdp

  4. sudo systemctl enable xrdp

  5. 退出您的会话。

  6. 尝试使用 RDP

答案4

您必须执行以下附加操作：

要配置 Xrdp，首先添加

exec gnome-session

到配置文件末尾

/etc/xrdp/xrdp.ini

或者使用以下命令将“exec gnome-session”添加到“/etc/xrdp/xrdp.ini”配置文件的末尾

sudo bash -c 'echo "exec gnome-session" >> /etc/xrdp/xrdp.ini'

重新启动 xrdp 以加载新配置

sudo systemctl restart xrdp
