据我记得，在以前的 Kubuntu 版本（18.10）上，当我按下 Ctrl-F9 时 - KWin 显示所有打开的窗口。但是升级到 19.04 后它不再工作了。在热键设置中，Ctrl-F9 仍然是此功能的快捷方式，但是当我按下它时 - 没有任何反应，我既不知道如何从命令行启动它以查看错误，也不知道在哪里查看日志。

我购买了预装了 Ubuntu 14.04 的 Dell Vostro 14 5480，将其重新安装到较新的 18.10 并面临令人不快的问题 - 音量非常低，最大设置质量差。我第一次在装有 Linux 的笔记本电脑上看到这样的东西，我非常失望。如果我插入耳机 - 没关系，质量好，音量好。

这是 alsamixer 屏幕截图 - 似乎所有相关内容都在最大设置上：

尝试将 Docker 安装到在 Ubuntu 16.04 上工作的 VirtualBox 来宾 - 它不起作用。

我遵循安装指南https://docs.docker.com/install/linux/docker-ce/ubuntu/#install-using-the-repository：

$ sudo apt install apt-transport-https ca-certificates curl software-properties-common
...
done.

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

今天买了 Wi-Fi USB 适配器 D-Link DWA-131。它不能“开箱即用”。尝试在 Ubuntu 14.04.4 下安装 DWA-131 WiFi 加密狗驱动程序的解决方案- 也没有帮助。

这是dmesg的结尾，希望它很重要：
