Configuring Fedora 32 for dev work

This a personal setup, not all settings might work for you. Read the document through and pick up the good parts to your preferences. Some tips may be meant only for Thinkpads or even the specific model T490.

Many of these tips or configs are for Gnome and X11, and should work with Ubuntu as well.

TODO

Stuff I haven't looked into yet:

Tips

  • Use Super + Left and other arrow keys to resize windows half-screen, full screen etc.
  • Use Ctrl + PgDown and Ctrl + PgUp for changing tabs in apps with keyboard.
  • Lenovo Thinkpad supports Fn + Right Arrow and Fn + Left Arrow for End and Home. Useful to go to the start or end of line. Unfortunately this didn't work with an external Lenovo keyboard and rebinding Fn at OS level is a bit tough.
  • Some times copy - pasting stuff to terminal with middle click brings up weidr [200~ chars, see: https://cirw.in/blog/bracketed-paste
  • Resize windows with Super + Mouse middle click and drag (Gnome)
  • Move windows with Super + Mouse left click and drag (Gnome)

Configuration

  • Settings -> Applications, disable notifications for all unnecessary apps.

  • Settings -> Displays -> Night Light tab: Schedule Night light in the evenings. Easier for your eyes.

  • Settings -> Sound. Drag System Sounds volume to zero to disable Gnome UI feedback sounds.

  • Settings -> Power. Configure so that you can leave a script running while on AC and laptop won't automatically shutdown or suspend.

  • Settings -> Keyboard shortcuts

  • Open Clocks app, add world clocks for all relevant office locations. These clocks appear in the notification menu when you click top bar clock.

  • Install Gnome Tweaks (appears as "Tweaks" app) to control even more Gnome options

    • Extensions
      • Set "overlay a tasteful logo" to disabled
    • Top bar
      • Disable Activities Overview Hot Corner
      • Clock: Weekday and date on
      • Calendar: Week numbers on
    • Window Titlebars
      • Titlebar Buttons, enable minimize and maximize
    • Workspaces
      • Set to Static Workspaces -> 2

  • To connect Bose QC35 with high quality audio. Follow these steps: https://askubuntu.com/a/885198.

    1. Before everything you can do a situation reset by removing Bose bluetooth device from your computer.

      Gnome settings can remove a device, but after that it still appeared in bluetoothctl for me:

      bluetoothctl

# Then in bluetooth shell
devices
remove XX:XX:XX:XX:XX:XX

      Then hold Bose power switch 10 seconds in the direction which normally starts pairing. After 10 secs it will remove all remembered devices from internal memory.

      Now you should be clear to start the reconnect process.

    2. Upgrade Bose firmware if possible

    3. Create /etc/bluetooth/audio.conf

      [General]
Disable=Socket
Disable=Headset
Enable=Media,Source,Sink,Gateway
AutoConnect=true
load-module module-switch-on-connect

    4. In /etc/bluetooth/main.conf set

      ControllerMode = bredr
AutoEnable=true

    5. Restart bluetooth

      sudo service bluetooth restart

    6. Connect your headphones

    7. Choose High Fidelity Playback (A2DP sink)-mode in sound options

    8. Configure autoswitching to bluetooth audio output on connection: https://askubuntu.com/questions/589885/automatically-switch-sound-output-device-to-bluetooth-headset-force-to-a2dp-pr

  • Terminal

    • Configure Ctrl + N as a shortcut for opening a new window

  • Configure windowing to use X11 instead of new default Wayland: https://docs.fedoraproject.org/en-US/quick-docs/configuring-xorg-as-default-gnome-session/

    With Wayland, bluetooth mouse refresh rate was very slow and sluggish.

  • alias open='xdg-open' Allows you to run open . in terminal to open file browser, and other files with defined protocol handlers.

    For example open $DATABASE_URL

  • Increase max_user_watches https://unix.stackexchange.com/questions/13751/kernel-inotify-watch-limit-reached

  • Use dead keys variant of keyboard for easier markdown backtick writing

  • Make Ctrl + Backspace delete whole words in terminals

    For bash, which uses readline, add "\C-H":"\C-W" to ~/.inputrc and restart bash. https://askubuntu.com/questions/701824/getting-ctrl-backspace-to-delete-words-in-gnome-terminal-and-vim-insert-mo

    For zsh, add bindkey '^H' backward-kill-word into ~/.zshrc. https://unix.stackexchange.com/questions/12787/zsh-kill-ctrl-backspace-ctrl-delete

  • Get Fn lock working with external Thinkpad keyboard: https://askubuntu.com/questions/889026/thinkpad-external-keyboard-fn-ctrl-switch

  • Setup Xmodmap for custom keyboard shortcuts. Use xev command to figure out keycodes. (more)

    Instructions for setup: https://wiki.archlinux.org/index.php/Xmodmap. Setting keyboard shortcuts is certainly possible in linux but the consensus how to do this varies A LOT. This seems to be the simplest way to setup keyboard mappings in Fedora 32 + X + Gnome.

    After setup, change keyboard mapping to have similar brace behavior as MacOS has. It is very logical, all needed characters are under keys 8 and 9.

    • Shift + 8 = (
    • AltGr + 8 = [
    • Shift + AltGr + 8 = {

    To list current mappings, run xmodmap -pke. We'll change a few items there. The fifth item is the one we want to change:

    -keycode  17 = 8 parenleft 8 asterisk bracketleft less
+keycode  17 = 8 parenleft 8 asterisk bracketleft braceleft
-keycode  18 = 9 parenright 9 parenleft bracketright greater
+keycode  18 = 9 parenright 9 parenleft bracketright braceright

    To do this on each startup, add the following lines to ~/.Xmodmap file:

    keycode  17 = 8 parenleft 8 asterisk bracketleft braceleft
keycode  18 = 9 parenright 9 parenleft bracketright braceright

    then run xmodmap ~/.Xmodmap to reload changes for current X session. To apply changes at startup, follow these instructions. In case the link dies, here's recap:

    Add following lines to a xdg startup items: nano ~/.config/autostart/xmodmap.desktop:

    [Desktop Entry]
Name[en_US]=Xmodmap
Comment[en_US]=xmodmap ~/.Xmodmap
Exec=/usr/bin/xmodmap .Xmodmap
Icon=application-default-icon
X-GNOME-Autostart-enabled=true
Type=Application

  • Install scm_breeze for very useful git shortcuts.

  • Install Git Cola for git UI.

    sudo dnf install git-cola

    It provides a nice way to stage changes by lines. For all other operations I use CLI. Git Cola was the best alternative for Sourcetree in my simple use case. Also add aliases:

    alias cola='git-cola'
alias stree='git-cola'  # old habits.. don't do this

  • Install z for jumping. I have it aliased as j for jumping to directories

  • Install VS Code

    My settings:

    {
    "window.zoomLevel": 3,
    "explorer.openEditors.visible": 0,
    "editor.renderWhitespace": "all",
    "files.trimTrailingWhitespace": true,
    "files.trimFinalNewlines": true,
    "git.decorations.enabled": false,
    // This option is needed to disable the behavior where Ctrl - X cuts
    // a line even when there's no selection
    "editor.emptySelectionClipboard": false,
    "explorer.confirmDragAndDrop": false,
    "workbench.editor.enablePreview": false,
    "workbench.editor.enablePreviewFromQuickOpen": false,
    "editor.tabSize": 2,
    "editor.rulers": [

    ],
    "typescript.updateImportsOnFileMove.enabled": "always",
    "update.showReleaseNotes": false,
    "editor.acceptSuggestionOnEnter": "off"
}

    Keyboard shortcuts:

    • Ctrl + Shift + L = add cursors to end of each selected line
    • Ctrl + X bindings might be useless, as I tried to get rid of Ctrl + X removing line without selection. I'm used to it only working as a clipboard shortcut.
    // Place your key bindings in this file to override the defaultsauto[]

Fn Lock with external Lenovo keyboard

Fn Lock didn't work in the external USB Lenovo keyboard, but there's an OS level way to toggle the switch. With this setup you can have a fnlock command available which will toggle it.

Into file /usr/local/sbin/fnlock write:

#!/bin/sh
#
# Usage: fnlock
# Toggles Fn Lock for Thinkpad keyboards
#  0: Fn Lock on
#  1: Fn Lock off

thinkpad_kb_glob='*17EF\:604*'

# Take the first device to check current fn lock value
# Doing it this way ensures that after 2 executions
# all devices are in sync.

paths=()
for device in $(find /sys/bus/hid/devices -name "$thinkpad_kb_glob"); do
  fnlock_path="$device/fn_lock"
  if [[ -f "$fnlock_path" ]]; then
    paths+=( $fnlock_path )
  fi
done


if [[ "${#paths[@]}" -eq 0 ]]; then
  echo "No matching devices found"
  exit 1
fi

current_val=$(cat ${paths[0]} | sed 's/ *$//')

if [[ "$current_val" -eq 0 ]]; then
  new_val="1"
else
  new_val="0"
fi


for fnlock_path in ${paths[@]}; do
  echo $new_val > $fnlock_path
done

if [[ "$new_val" -eq 0 ]]; then echo "Fn Lock ON"; else echo "Fn Lock OFF"; fi

then add a way to execute this script without writing a password for sudo. Run sudo visudo and add:

ALL ALL=NOPASSWD: /usr/local/sbin/fnlock

then add an alias alias fnlock='sudo fnlock' to bind it automatically to sudo usage.

After that you can just type fnlock in terminal to switch the toggle. Enjoy!
