使用 Chrome 看起来不错：
但是对于 Chromium，它看起来很奇怪：
版本：
Google Chrome 99.0.4844.51（官方版本）（64 位）
Chromium 98.0.4758.102（Offizieller 构建）快照（64 位）
网址：https ://thomas-guettler.de/tmp/peacefood.coffee-and-sugar.club.html
同样奇怪的合理布局在我们的本地 Gitlab 中。
可能是什么原因？
顺便说一句，它也发生在快速入门页面上。
如果我在 Chromium 的视频通话中使用“模糊背景”功能，那么 CPU 风扇会变得非常响亮。
我有相当新的联想笔记本电脑。
也许 Chromium 不能使用硬件加速。

如何在我的笔记本电脑上启用硬件加速？
版本：带有 X11 的 Ubuntu 21.04（不是 Wayland）
我通过 CapsLock 制作了 Hyper-keygnome-tweaks
抱歉，我只有德语截图。“Feststelltaste”的意思是“CapsLock”
现在我想映射
Hyper-u至Arrow-UpHyper-n至Arrow-DownHyper-i至Page-UpHyper-m至Page-downHyper-j至Pos1Hyper-ö到End（在我的德语布局中，这个字符对“l”是正确的）如果这可以通过在 $HOME 中进行配置来完成，那就太好了。
例如通过 .xmodmaprc
相关问题：使箭头向上/向下、Pos1、End、Del ... 更容易
我对所有可行的解决方案持开放态度。也许有办法通过 eBPF 或自己的 uinput-device 解决这个问题？
我喜欢当时的手指触摸打字。我对我为 aZ 设计的 QWERTZ 布局感到满意。但这些特殊的按键总是让我离开舒适的位置，将食指放在“F”和“J”上。
我用十个手指在“F”和“J”上打字。
通过这种方式，我可以使用 QWERTZ 布局快速轻松地键入字母表。
但是许多其他键很难触及。例如：
Pos1、End、Del、Arrow-Up/Down、Page-Up/Down、ESC、Backspace。
有没有办法让这些键可用，同时将指针保持在“F”和“J”上？
我对“A”到“Z”很满意，不想切换到不同的布局（例如Colemak）
也许通过使 CapsLock 成为一个新的修饰符，以便（例如）CapsLock-u 是向上箭头而 CapsLock-n 是向下箭头？
我使用 Ubuntu Linux。
我创建了一个后续问题：Hyper-key u --> Like Arrow-Up
我找到了一个很好的解决方案：input-remapper。看我的小文章十个飞手指（触摸打字更舒服）
如果我想在 Chromium 中共享屏幕，我只会看到黑屏。
我可以共享屏幕，但其他参与者只能看到黑屏。
共享窗口或铬标签可以正常工作。
我使用 Ubuntu 21.10
有没有办法让共享屏幕再次起作用？
它与 microsoft-teams 无关，因为如果我使用 slack 的 web 版本，这也是同样的问题。

如果我创建一个新的 Python 文件gedit，则默认使用 Tabs 作为缩进。
我确信我可以找到一种方法来配置 gedit 以将其更改为四个空格。
但我有不同的目标。
我希望将来为所有 Ubuntu 用户更改此设置。
如何为所有未来的 Ubuntu 用户（全球）改变这一点？
我想将一些图像从 Digikam 复制到 Nautilus。
不知何故，我更喜欢 ctrl-c 和 ctrl-v 拖放。
Nautilus 中的上下文菜单是空的，尽管我在 Digikam 中选择并复制了一些文件。
我究竟做错了什么？
如果我使用 ALT+TAB，有些日子CopyQ是可见的：
这在过去是不同的。
我认为显示这个窗口没有意义。您通常使用快捷方式打开剪贴板管理器。
如何再次隐藏此窗口？
我使用默认的 Ubuntu 20.04 Gnome 环境
vagrant up在内核 5.8.0-36-generic 的 Ubuntu 20.04 上失败
我能做些什么来解决这个问题？
这是我当前的调试状态：
guettli@yoga15:~/projects/yourfirm$ vagrant up
The provider 'virtualbox' that was requested to back the machine
'default' is reporting that it isn't usable on this system. The
reason is shown below:

AFAIK Virtualbox 6.1.16 可以解决这个问题，但这还不可用：
几天前我安装了 Ubuntu 20.04。大多数事情工作得很好。
但是如果我通过 LAN 连接，我会一次又一次地收到 WiFi 无法连接的警告。
这根本不符合逻辑。
如果我有 LAN，那么我不需要 WiFi。
当然我可以手动禁用它，但是默认的自动化就可以了。
我能做些什么来解决这个问题？
过去dconf-editor可以用来改变光标大小。
我安装了 Ubuntu 20.04。我将值更改为64rebooted，但光标的大小仍然没有改变。
如何在 Ubuntu 20.04 上增加光标大小？
今天我参加了一个使用 Chromium 的 Google Hangout 视频会议。质量非常低。换句话说，无法使用。
这不是 wifi 连接。我带着一本mac book参加了同一个会议，那里的质量很好。我在两分钟内切换了两次：Ubuntu 笔记本电脑（无法使用）、Mac（良好）、Ubuntu 笔记本电脑（无法使用）、Mac（良好）。
ubuntu 笔记本电脑变得非常慢。在浏览器和终端之间切换需要几分钟。
版本：Chromium 79.0.3945.79，在 Ubuntu 18.04（64 位）上运行
这是lshw我笔记本电脑的输出：https ://pastebin.com/uw8aCbGQ
我的 ubuntu 笔记本电脑质量非常低的原因可能是什么？
我想删除所有包含/424/.
我可以列出所有匹配的条目：
但是我找不到一次删除所有这些条目的方法。
有没有办法一次删除所有包含一个术语的条目？
我在 wiki.ubuntu.com 上发现了一个非常过时的页面：
https://wiki.ubuntu.com/ScreenCasts/Istanbul
“伊斯坦布尔”截屏软件看起来已经死了。主页已消失，自 2007 年以来未更新。
wiki 页面受到保护。我不能删除它。
我可以做些什么来清理 wiki？
（整个区域（https://wiki.ubuntu.com/ScreenCasts/）已过时。Kazam 工作正常）。
有没有办法像在 android 上一样进行单词预测？
就像在这个屏幕截图上一样：
这将大大提高在 Ubuntu 上的打字速度。
我在这里需要它：
所需功能：
更新
我为这个问题提供了赏金，但仍然没有答案。估计桌面快不行了。我想迟早我会使用 android 而不是 ubuntu。
如果我将 LibreOffice 表（电子表格，而不是编写器）复制到 CKEDitor4，它会复制并粘贴图像。
使用 CKEditor5 复制表格。
有没有办法让它与 CKEditor4 一起工作？
