在 Ubuntu 16.04.6 LTS Xenial 机器上，我像这样设置 xRDP：
sudo apt-get update
sudo apt-get install -y xrdp mate-core mate-desktop-environment mate-notification-daemon
sudo sed -i.bak '/fi/a #xrdp 多用户配置 \n mate-session \n' /etc/xrdp/startwm.sh
sudo ufw allow 3389
sudo shutdown -r now从 MS-Win10 连接看起来按预期工作：
- 输入登录名和密码信息后，我看到此屏幕：
- 几秒钟后，我的连接就断开了。
文件.xsession 错误看起来像这样：

请问我该如何修复此问题？
答案1
好的，这个看起来很有趣:-)
第一的，Ubuntu 16.04.x 不是 EOL...它是一个 LTS 版本，将支持到2021年....（但我确实同意这是一个旧的 Ubuntu 版本，也许是时候迁移到最新版本了......比如今天发布的 Ubuntu 20.04）
第二，关于你的问题……嗯
选项 1 - 保留旧的 xrdp 包并连接到 Mate Desktop
因此，问题似乎与 mate-session 在远程会话中无法正确启动有关......
- 您是否尝试过使用 mate-session 在机器上本地登录？
- 如果这不起作用，请在 Ubuntu 上重新安装 mate-desktop 软件。确保您的 Ubuntu 16.04 机器上有 mate 桌面存储库
- 如果此操作有效，请检查文件 /etc/xrdp/startwm.sh，并确保文件底部有以下行配对会话存在。
选项 2 - 安装较新的 xrdp 版本并使用 Unity Desktop
使用以前版本的 xrdp 包，无法访问 Unity Desktop...如果您决定使用较新的 xrdp 包，您应该能够从远程会话中使用 Unity Desktop
您可以尝试使用 xrdp-installer-v1.x.sh 脚本在 Ubuntu 16.04.x 上轻松自动安装较新的 xrdp 软件包，并允许您连接到 Unity Desktop。您可以在此处找到该脚本及其使用说明邮政
使用脚本非常简单
步骤 1 - 下载脚本
wget https://www.c-nergy.be/downloads/xrdp-installer-1.1.zip
第 2 步 - 解压
unzip xrdp-installer-1.1.zip
步骤 3 - 将其标记为可执行文件
chmod +x xrdp-installer-1.1.sh
步骤 4 - 使用参数执行脚本以启用您选择的选项
./xrdp-installer-1.1.sh -h (for the help)
./xrdp-installer-1.1.sh (install xrdp using xrdp ubuntu packages )
./xrdp-installer-1.1.sh -c (install xrdp from sources )
....
由于 Ubuntu 20.04 即将发布，预计将发布新版本的脚本来修复一些小错误并包含对 Ubuntu 20.04 的支持
还请注意，如果用户 A 在 PC 上本地登录，则用户 A 将无法远程连接（登录远程会话后将断开连接）。如果用户 A 远程连接，则将无法在机器上本地登录（登录循环）。这是一个需要注意的限制
希望这能有所帮助，下次再见
