在Ubuntu 22.04中使用gsettings设置键盘快捷键（有什么变化？）

  • 772

看起来使用gsettings和命令行在Ubuntu 22.04上设置Super+C来启动我的GNOME计算器应该相对容易：

gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom999/ name "Launch Calculator"
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom999/ binding "c"
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom999/ command "gnome-calculator"

我执行了命令，一切看起来都很正常，然后我按下Super+C，但什么也没发生。我做错了什么？

这将是脚本的一部分，所以我不能使用任何图形界面解决方案，尽管我们可以使用图形界面（dconf、设置等）进行故障排除。实际上，我已经这样做了，我可以看到快捷方式列在我的

dconf > org > gnome > settings-daemon > plugins > media-keys > custom-keybindings

但在

Settings > Keyboard > Keyboard Shortcuts > View and Customize Shortcuts

中缺失，这似乎是我按下Super+C时"什么也没发生"的症状。

    每个自定义目录（以/结尾）你添加到目录下

    /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/

    （这是一个以/结尾的目录）需要将其路径作为值条目添加到键

    /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings

    （这是一个与上述目录同名但不以/结尾的键）
    ... 并且你可以使用以下命令读取其当前值：

    dconf read /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings

    所以，除了创建自定义目录并像这样填充键和值（使用dconf）：

    dconf write /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom999/binding "'<Super>c'"
dconf write /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom999/command "'gnome-calculator'"
dconf write /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom999/name "'Launch Calculator'"

    ... 你可以通过dconf dump这样验证：

    $ dconf dump /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom999/
[/]
binding='<Super>c'
command='gnome-calculator'
name='Launch Calculator'

    ... 你需要将其路径添加到/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings键中，同时保留该键数组中已有的值['...', '...', ...]，像这样：

    if [ -z "$(dconf read /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings | tr -d '][')" ]; then
  dconf write /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings "['/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom999/']"
  else
  dconf write /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings "[$(dconf read /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings | tr -d '][') , '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom999/']"
fi

    ... 你可以通过dconf read这样验证：

    $ dconf read /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/', '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom999/']

    注意我使用了dconf工具，因为它默认在所有Ubuntu安装中都可用，因此特别适合广泛部署的脚本，但你可以安装gsettings前端工具并使用它修改上述命令的语法和目录/键路径风格以适应它... 请查看man gsettings并在使用之前查看gsettings list-schemas和gsettings list-recursively的输出。
