在 Ubuntu 20.04 上 - 我安装了 Easy Tether light（无根）以使用我的 android 手机的蜂窝连接进行 USB 网络共享，以便在我的计算机上获取 wifi。我使用此处的说明下载我执行的 deb 文件。

在命令行中，我按照说明输入了此代码。

systemctl restart systemd-networkd

这成功地使用我的手机获得了 wifi。现在电话已断开连接，我无法连接到我的家庭 wifi 网络。在设置 - wifi 中，我看到一条消息“未找到 WI-FI 适配器。

如何让 WiFi 在我的计算机上再次运行？

这是评论中要求的输出。

我有一个新安装的 20.04。我有双显示器。在一台显示器上有顶部（活动）栏。第二个是收藏夹侧栏，我有我最喜欢的应用程序的快捷方式。如果我将一台显示器设置为主显示器，则活动栏会移动到该显示器，但收藏夹会移动到另一台显示器（反之亦然）。如何在同一台显示器上同时获取收藏夹和活动？

我刚刚升级到 Ubuntu 20.04。当我打开一个应用程序然后打开该应用程序的任何弹出窗口时，移动弹出窗口会移动带有弹出窗口的主窗口。

我想将弹出窗口移出主窗口，以查看弹出窗口中的操作和设置如何影响主应用程序。

如何将弹出窗口的移动动作与主窗口分开？

我的家用电脑运行的是 Ubuntu 18.04。我有一台运行 Windows 10 的类似配置的工作计算机。两台计算机都是大约 4 年的戴尔计算机。在我的 Ubuntu 电脑上——当我访问一些网站、在谷歌地球上滚动、处理数据时——硬盘开始疯狂旋转，风扇开始运转，就好像电脑在挣扎一样。我注意到我的 Windows 计算机在执行相同任务时没有相同的问题。访问网站时风扇永远不会启动，只有在我处理大量图像文件时。

我已确保我的 Ubuntu 计算机的组件没有灰尘，并且通风口畅通无阻。

为什么我的 Ubuntu 计算机似乎在简单的任务上如此挣扎？

以下是 Windows 10 计算机的统计数据。

在此处输入图像描述

升级到 20.04 后，我的问题又回来了。这是当前的驱动程序。

在我的 Ubuntu 18.04 计算机上，我再也看不到（以前工作的）USB 连接设备（拇指驱动器和外部硬盘驱动器）。当我连接其中一个设备时，我会听到设备正在连接的声音。我可以在磁盘中看到这些设备。我无法访问 PCmanFM、Thunar 或 Nautilus 中的设备，因为没有显示驱动器。

我的蓝牙鼠标和 USB 键盘工作正常。

我最近确实进行了更新并安装了 Minecraft，这些是计算机上发生的唯一更改。

发现问题后，我进行了另一次更新并重新启动计算机，但这并没有解决问题。

如何让这些外部存储设备显示在我的文件浏览器中？为什么会发生这种情况？

请知道我对 Ubuntu 比较陌生，所以请相应地回答。

我是 Linux 和 Ubuntu 的新手，我正在为文件路径名和位置而苦苦挣扎。我有一台安装了 LTS 16.04 的新计算机。这台计算机有一个固态硬盘驱动器和一个光驱。在 Nautilus 中，SSHD 的名称是2.0 TB Volume。当我想在不同的应用程序中打开一些文件时，我看不到 2.0 TB 卷，我不得不转到 /media/USERNAME/02689296-24e3-4e9b-b940-b33bdbbcab43。

为什么名称会根据我是在 Nautilus 还是应用程序中搜索而改变？为什么是神秘的 SSHHD 名称？我可以重命名 02689296-24e3-4e9b-b940-b33bdbbcab43 之类的SSHD并让该名称出现在任何文件浏览器中吗？

我是 Linux 新手，但不是 Python。我正在尝试将我的 Python 技能迁移到 Linux。使用 Windows，我可以使用默认查看器打开图像文件。

import os
os.system(r"C:\gTemp\Capture.JPG")

使用有效的 Linux 路径，相同的代码会返回“权限被拒绝”

import os
os.system(/home/myname/Capture.JPG")

为什么我会收到此错误，我该如何解决？我正在使用 16.04 和 Python 2.7
