        "1. 调通: rustdesk seemless 模式启动 x-server，目测效果有限，因为手动需要定制的很多，自动模式功能有限?\n",
        "2. 修复: 声音支持，原来可以，后来不知道哪里改的又不行了？\n",
        "3. 优化X启动: 目测调用/etc/X11/Xsession是一个更好的做法？避免自己管理一堆上下文？\n",
        "   /etc/X11/Xsession会自动处理dbus等一系列问题？ 通过dbus-x11增加进入/etc/X11/Xsession.d的文件可知\n",

        "5. 上游优化和联调: seemless不工作的的问题，也许后续会修?https://www.reddit.com/r/rustdesk/comments/1cuum90/i_cant_seem_to_make_rustdesk_service_work_on_linux/\n",
        "6. 支持 SD： oobabooga/text-generation-webui\n",
        "   Project page: https://github.com/oobabooga/text-generation-webui\n",
        "7. 支持Gnome桌面环境联调: 使用elogind，以支持在容器里面(非systemd环境)运行gnome\n",
        "    icewm还是太简单，gnome最强大和完善\n",
        "    xfce(任务栏无法显示)=>icewm(太简单)=>gnome(最强大)\n",

        "   Colab基于 ubuntu 镜像, 不支持elogind，所以需要内嵌docker来执行?\n",
