在 Ubuntu 17.10 及更高版本上禁用默认应用程序密钥 (super+num) 功能

Question

我喜欢通过Super+切换工作区Number。但不幸的是，Ubuntu 中Super+的默认行为Number是从 Dock 中选择应用程序。

是否可以禁用该功能？我试过覆盖键盘快捷键，但它似乎不起作用。

Answer 1

对于 Ubuntu 17.10 - 18.10

在终端中运行以下命令：

gsettings set org.gnome.shell.extensions.dash-to-dock hot-keys false

这应该禁用Super+ 0...的默认行为9。

对于 Ubuntu 19.04

除了Nolf 的回答之外，您还可以使用以下命令在命令行上设置这些设置：

gsettings set org.gnome.shell.extensions.dash-to-dock hot-keys false
gsettings set org.gnome.shell.keybindings switch-to-application-1 []
gsettings set org.gnome.shell.keybindings switch-to-application-2 []
gsettings set org.gnome.shell.keybindings switch-to-application-3 []
gsettings set org.gnome.shell.keybindings switch-to-application-4 []
gsettings set org.gnome.shell.keybindings switch-to-application-5 []
gsettings set org.gnome.shell.keybindings switch-to-application-6 []
gsettings set org.gnome.shell.keybindings switch-to-application-7 []
gsettings set org.gnome.shell.keybindings switch-to-application-8 []
gsettings set org.gnome.shell.keybindings switch-to-application-9 []

更新：

我现在正在使用Dash to Panel（而不是Dash to Dock）并再次遇到同样的问题。现在我们需要这些命令：

dconf write /org/gnome/shell/extensions/dash-to-panel/hot-keys false
dconf write /org/gnome/shell/extensions/dash-to-panel/hotkey-prefix-text "''"

然后关闭和打开扩展应该使它工作。

Answer 3

对于 Ubuntu 19.04

安装dconf-editor( sudo apt install dconf-editor) 并打开dconf-editor。用空括号“ []”替换键盘快捷键，如屏幕截图所示。

Answer 4

对于 Ubuntu 20.04.4 这已经足够了：

gsettings set org.gnome.shell.extensions.dash-to-dock hot-keys false
for i in $(seq 1 9); do gsettings set org.gnome.shell.keybindings switch-to-application-${i} '[]'; done
