This is a beginner’s guide on how to easily extend the functionality of GNOME Shell on Ubuntu 20.04 LTS and Ubuntu 20.10.
By default, Ubuntu includes three extensions: desktop icons, Ubuntu AppIndicators, and Ubuntu Dock.
In addition to installing more from Gnome Shell Extended WebsiteYou can run a single command to get a collection of extensions that provide additional and optional functionality.
The extensions are:
- Application Menu – Adds a classic Gnome2 menu to the top bar immediately after an activity.
- Automatically move windows – Moves an application to a specific workspace when the application creates a window.
- Horizontal workspace – Use a horizontal workspace layout.
- Launch a new instance – Whenever you click an app shortcut on the dashboard or application menu, launch a new instance.
- Place Native Window – Place the window in the overview in a more compact way.
- Place Status Indicator – Add a menu to the top bar to quickly access your user folders.
- Removable Drive Menu – Add a system tray indicator for easy access and dismounting of removable devices.
- Screenshot Window Sizar – Resizes the gnome software screenshot window.
- User Theme – Loads the shell theme from the uer directory.
- Window List – Shows the window list at the bottom of the screen.
- Workspace Indicator – Adds a system tray applet to the current workspace indicator.
1. The command is as follows (press Ctrl + Alt + T to open a terminal and execute the command):
sudo apt install gnome-shell-extensions gnome-shell-extension-prefs
2. After running the command, restart Gnome Shell as follows:
- Press Alt + F2 on your keyboard.
- Of the pop-up[コマンドの実行]Try r in the box.
- Press Enter.
3. Finally, open (or reopen) the Extensions tool from the apps menu. A list of new extensions is displayed. Enable any of them and have fun as you like!
(Optional) If you don’t like them, run the command to remove the package (you’ll need to restart Gnome Shell).
sudo apt remove gnome-shell-extensions
Note to Clean Freaks: If you need one or several extensions, you can’t remove the package to hide it from the rest of the extension tools. As a workaround, you can install the required extensions from extensions.gnome.org.
