Xfce

Whisker Menu

For some reason not all distributions have a shortcut to Whisker Menu, which is remarkably annoying. To add it: "Keyboard" → "Application Shortcuts" → "xfce4-popup-whiskermenu".

Using shortcut Super + Space* is advised when using Compiz, simply using Super will prevent Compiz shortcuts that use the Super button as well.

* The Super button is the Windows button with the ⊞ icon.

xfce4-screensaver

"Where are all the screensavers?" XScreenSaver is used by xfce4-screensaver, but doesn't add all of XScreenSaver's screensavers by default. Annoying. To add one of its screensavers, place the file xfce-glmatrix.desktop containing the lines below in /usr/share/applications/screensavers/. All XScreenSaver's screensavers and their options can be found in /usr/share/xscreensaver/config/.

[Desktop Entry]
Type=Application
Name=glmatrix
Exec=/usr/lib/xscreensaver/glmatrix -root --no-rotate
TryExec=/usr/lib/xscreensaver/glmatrix
Categories=Screensaver;

Window tiling

xfwm4

To enable window tiling when nearing the edge of a screen, open "Window Manager Tweaks" and enable "☑ Automatically tile windows when moving towards the screen edge".

However, this will sneakily deselect and thus disable within "Window Manager" → "Wrap workspaces when reaching the screen edge", the option "☐ With a dragged window". This means one cannot grab and move a window towards another workspace.

Compiz

Stopped using Compiz because its latest update was three years ago.

To autostart Compiz, here in Xfce, execute:

xfconf-query -c xfce4-session -p /sessions/Failsafe/Client0_Command -t string -sa xfsettingsd
  xfconf-query -c xfce4-session -p /sessions/Failsafe/Client1_Command -t string -sa compiz

CompizConfig Settings Manager:

• General Options → Desktop Size: 2 × 2.
• ☑: Expo, Desktop Cube, Rotate Cube, Viewport Switcher…
  Within "Viewport Switcher" → "Desktop-based Viewport Switching", disable "Initiate plugin action", or don't select "Button 2" for it not to interfere with middle mouse button functionality in other software.
• In case shortcut Super + e doesn't launch Expo mode, then make sure xfce4-popup-whiskermenu isn't assigned Super as shortcut in "Keyboard" → "Application Shortcuts"; this is a known bug in Xfce.

KDE Plasma

Custom KRunner/Plasma browser search query

To configure Plasma search to open a browser with a query when entering "xyz example.com", e.g., "viv example.com" that opens example.com in Vivaldi browser:

“create a symlink named "viv" in /usr/bin/ to the actual vivaldi binary” —Jan R..

Either there likely already is a symlink named "vivaldi" within /usr/bin/, of which you can make another symlink with a more convenient shorter name: sudo ln -s vivaldi viv

Or go to the directory containing the vivaldi binary, in my case "/opt/vivaldi/", and in that directory run the command: sudo ln -s vivaldi /usr/bin/viv

Web Search Keywords backup

To back up all your custom websites added to the Web Search Keywords KRunner plugin, navigate to ~/.local/share/kf6/searchproviders/ and back up the containing files.

Revert to X11 from Wayland

The upgrade from KDE Plasma 5 to 6 enables Wayland by default despite using X11 before, and it breaks tons of stuff, e.g., Vivaldi browser became unusable, XScreenSaver does not work, et cetera. To revert to X11 open SDDM → Behaviour… → Automatically log in…with session Plasma (X11).

How to reauthorise a Gmail account in KMail

Open kdewallet with kdewalletmanager and delete "akonadi_imap_resource_…" in "Contents" → "imap" → "Passwords".

How to make a unified folder in KMail.

Go to "Settings" → "Plugins" → "Akonadi Agents", and click the slider icon 🎚️ next to "Unified Mailbox Agent".

XScreenSaver in KDE Plasma

To change the minimap colors, etc. [source 1, 2, 3, 4], go to File → Preferences → Settings → in the search box, type: workbench.colorCustomizations → click "Edit in settings.json"

{
    "editor.tabSize": 2,
    "editor.wordWrap": "on",
    "cSpell.language": "en-GB",
    "editor.minimap.showSlider": "always",

      "scrollbarSlider.activeBackground": "#95efff",
      "scrollbarSlider.hoverBackground": "#c0ebff",
      "scrollbarSlider.background": "#5e6368",
    },
    "workbench.colorTheme": "Visual Studio Dark",

    "editor.fontSize": 16,
    "editor.hover.above": false,
    "editor.hover.delay": 700,
}

Frequently used shortcuts:

• To select multiple instances of the same character combination, select the combination (word, sentence, etc.) and press: control + shift + L
• Select multiple instances of the same isolated word: place the cursor on the word and press: control + shift + L
• Rename the opening/closing tag pairs in HTML: place the cursor on the tag and press F2.
• Wrap selected text with tags: control + shift + P and select "Emmet: Wrap with Abbreviation".
• Multiple selections (multi-cursor): alt + click and/or add more with: shift + alt + up/down
• Select word at cursor or the next occurrence of the current selection: control + D
• Comment out a selection: control + shift + A
• Comment out an entire line: control + /

Automatically execute a Python script in VSCodium when it is updated

1. sudo pacman -S inotify-tools
2. Create a shell script e.g., "auto_execute.sh" containing the code below:
   

   #!/bin/bash
   while inotifywait -e modify,move_self -qq your_python_script.py; do
     python3 your_python_script.py
   done

   Make sure the shell script is executable by right clicking it → "Properties" → "Permissions" → "Program: ☑ Allow this file to run as a program", or by running the following command: chmod +x auto_execute.sh
3. Open the terminal in VSCodium and run auto_execute.sh

Now, whenever you save "your_python_script.py", it will instantly throw the output in the VSCodium terminal, or whatever terminal you executed the shell script in. Source: ChatGPT.

By default Zed uses the VSCode/VSCodium keymappings, and it supports Emmet. However, for some reason, "Emmet: wrap with abbreviation" is not supported yet, which I frequently use to wrap HTML tags around words with. In the meantime one can use AutoKey by assigning the following script to a hotkey:

To build LyX one needs packages make automake autoconf, otherwise it throws the following error:

Unplug the Ethernet cable and disable Wi-Fi. When prompted to enter an email address press Shift + F10, and in cmd.exe type oobe\BypassNRO and press enter to reboot. Then click "I don't have internet" → "Continue with limited setup". When asked to enter your name type "Screw Microsoft". Unethical bastards.

If Shift + F10 does not launch anything except for a split-second loading icon, then just use no@thankyou.com as the email address and enter any arbitrary password; "Screw Microsoft" remains an appropriate choice.
