Gnome3 - добавление клавиатуры "Пользовательские сочетания клавиш" с использованием dconf без необходимости выхода из системы

Вы можете использовать GSettings

Простой скрипт:

#!/bin/bash

gsettings set org.gnome.settings-daemon.plugins.media-keys custom-keybindings "['/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/', '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom1/']"

# Keybind 0
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/ binding "<Super>c"
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/ command "gnome-calculator"
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/ name "Calculator"

# Keybind 1
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom1/ binding "<Super>z"
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom1/ command "gnome-system-monitor"
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom1/ name "System Monitor"

Для этой цели я написал специальный скрипт.

Использование:

add_keyboard_shortcut "MyShortcut#1" "gedit" "<Control>F8"

А вот и скрипт:

#!/bin/bash
    
has_gsettings=$(which gsettings)
if [[ ! -z "$has_gsettings" ]]; then
  function add_keyboard_shortcut ()
  {
    existing_shortcut_string=$(gsettings get org.gnome.settings-daemon.plugins.media-keys custom-keybindings)
    exst_str_len=$((${#existing_shortcut_string}))
    if (( $exst_str_len < 9 )); then
      existing_shortcut_count=0
    else
      IFS=', ' read -ra existing_shortcut_array <<< "$existing_shortcut_string"
      existing_shortcut_count="${#existing_shortcut_array[@]}"
    fi
    new_shortcut_index=$(("$existing_shortcut_count"))
    declaration_string=' ['
    for (( i=0; i<="$existing_shortcut_count"; i++ )); do
      if (( $i == 0 ))
      then
        declaration_string="$declaration_string""'/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom$i/'"
      else
        declaration_string="$declaration_string"", '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom$i/'"
      fi
    done
    declaration_string="$declaration_string"']'
    if [[ ! -z "$1" ]] && [[ ! -z "$2" ]] && [[ ! -z "$3" ]]; then
      printf "\nFound %s existing custom shortcuts.\n\n" "$existing_shortcut_count"
      printf 'Setting new custom keyboard shortcut "%s" => %s' "$1" "$2"
      gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom$new_shortcut_index/ name "$1"
      gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom$new_shortcut_index/ command "$2"
      gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom$new_shortcut_index/ binding "$3"
      gsettings set org.gnome.settings-daemon.plugins.media-keys custom-keybindings "${declaration_string}"
    else
      printf "\n\nYou are missing input arguments.\n\nThis command requires 3 arguments...\n\nSyntax is add_keyboard_shortcut 'Name' 'Command' 'Shorcut'\n\n\nFor example\n\n  add_keyboard_shortcut 'Open Nautilus' 'nautilus' '<Control>F3'\n\n\n\n\n\nCommon Key Abbreviations:\n\n";
