Ubuntu 16.04.6 上的 xRDP 问题

  • 772

  1. 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 允许 3389
    sudo shutdown -r now

  2. 从 MS-Win10 连接看起来可以按预期工作：

  1. 输入登录名和密码信息后，我得到这个屏幕：

  1. 几秒钟后，我断开了连接。

文件.xsession-errors如下所示：

请问我该如何解决这个问题？

16.04 xrdp

1 个回答

  1. Best Answer

    好的，这个看起来很有趣:-)

    首先， Ubuntu 16.04.x 不是 EOL ......这是一个 LTS 版本，将支持到2021 年......（但我同意这是一个旧的 Ubuntu 版本，可能是时候转移到最近的版本了......比如今天发布的 Ubuntu 20.04）

    其次，关于你的问题......嗯

    选项 1 - 保留旧 xrdp 包并连接到 Mate 桌面

    因此，问题似乎与 mate-session 在远程会话中未正确启动的事实有关....

    • 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 机器上可以使用 mate 桌面存储库
    • 如果这有效，请检查文件 /etc/xrdp/startwm.sh 并确保在文件底部存在mate-session行。

    选项 2 - 安装更新的 xrdp 版本并使用 Unity 桌面

    使用以前版本的 xrdp 包，无法访问 Unity 桌面...如果您决定使用更新的 xrdp 包，您应该能够从远程会话使用 Unity 桌面

    您可以尝试使用 xrdp-installer-v1.x.sh 脚本在 Ubuntu 16.04.x 上轻松并自动安装较新的 xrdp 软件包，并允许您连接到 Unity Desktop。您可以在这篇文章中找到脚本以及如何使用它的说明

    使用脚本非常简单

    第 1 步 - 下载脚本

    wget https://www.c-nergy.be/downloads/xrdp-installer-1.1.zip

    第 2 步 - 解压缩

    unzip xrdp-installer-1.1.zip

    第 3 步 - 将其标记为可执行文件

    chmod +x xrdp-installer-1.1.sh

    第 4 步 - 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以修复一些小错误并包括对 Ubuntu 20.04 的支持

    另请注意，如果用户 A 在 PC 上本地登录，用户 A 将无法远程连接（登录到远程会话后将断开连接）。如果远程连接，用户 A 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

    希望这对下次有帮助
