This simple tutorial shows how to enable ‘minimize on click’, minimize running app window when clicking on its icon on the left dock panel.
All the opened app icons are docked on the left panel in Ubuntu GNOME desktop. Unlike Windows, it however does not minimize focused app when you click its icon on the dock. And, neither “System Setting” nor “Gnome Tweaks” has option to enable this action.
Since the Ubuntu dock is handled by the dash-to-dock extension, it does have the option to enable the feature. All current Ubuntu releases, including Ubuntu 18.04, Ubuntu 20.04, Ubuntu 22.04, and Ubuntu 24.04, can enable this feature via following steps.
Single command to enable ‘Minimize on click’:
The dash-to-dock Gnome extension in Ubuntu is called ‘Ubuntu Dock’. As the built-in extension, it does not provide settings page in ‘Gnome Extensions’ app. However, users may run single command to change its options one by one.

gsettings set org.gnome.shell.extensions.dash-to-dock click-action minimize
After that, click on dock icon to open or focus an app, and click again to see effect!

In Ubuntu 24.04, user can first launch App Center, then search for and install the Extension Manager tool.
Install Extension Manager in Ubuntu Software/App Center
Then, launch “Extension Manager” and click the setting icon for “Ubuntu Dock” extension to open its preferences dialog.
In next pop-up dialog, you’ll see lots of options to configure the left dock panel. There, navigate to “Behavior” tab and set “Click action” to minimize, will do the trick enabling click app icon to minimize its window.
Enable ‘Minimize on click’ via Dconf Editor (Graphical Tool):

1.) Firstly, search for and install ‘dconf editor’ via Ubuntu Software if you don’t have it.
2.) Next, search for and open the tool from the upper-left Activities overview, and then navigate to org -> gnome -> shell -> extensions -> dash-to-dock.
Then scroll down and find out settings for ‘click-action’, and do:
click the line to go into its configuration page.
turn off the default value switch.
select ‘minimize’ as Custom value.
You may also set the value to ‘minimize-or-overview’, which will go to overview screen if more than one windows of the same app are opened; or ‘minimize-or-previews’ that opens thumbnail preview if multiple app instances exist.
This quick tutorial is going to show beginners how to install and manage Gnome Shell Extensions in Ubuntu 17.10 while it uses Gnome Shell as default desktop environment.
Gnome Shell Extensions are small pieces of code written by third party developers. If you are familiar with Chrome Extensions or Firefox Addons, GNOME Shell extensions are similar to them.
How to Install Gnome Shell Extensions
Gnome maintains a website, extensions.gnome.org, for users to install or upgrade extensions. All extensions there are carefully reviewed for malicious behavior before they are made available for download.

Due to legal reasons, Ubuntu does NOT include multi-media codecs out-of-the-box for audio and video playback. It’s however easy to install them via a single command.
During the Ubuntu installing process, it provides an option “Install third party software for graphics and Wi-Fi hardware and additional media formats” in the wizard. If you didn’t enable it, Ubuntu refuses to play movie and sound via the default Totem media player and Rhythmbox music player.
Without installing third-party player with bundled codecs, you can simply install the ubuntu-restricted-extras package to fix the issue. The package does not contain anything, but tells to install the following packages for you:
ttf-mscorefonts-installer – Install Microsoft TrueType core fonts.
unrar – non-free package enables ability to extract rar package in Ubuntu.
libavcodec-extra – FFmpeg library with encoder / decoder for audio and video codecs.
chromium-codecs-ffmpeg-extra – FFmpeg codecs for Chromium based web browser.
And a few gstreamer1.0 plugins for audio / video playback, recording and editing.
How to Install Media Codecs in Ubuntu:
Firstly, open a terminal window either by searching from the ‘Activities‘ overview screen or by pressing Ctrl+Alt+T on keyboard.
When terminal opens, copy and paste the command below into it and hit Enter:
1. Open terminal via Ctrl+Alt+T or from application launcher. Remove old Virtualbox via command:
sudo apt-get remove virtualbox virtualbox-5.1
2. Download & install the latest Virtualbox package from the link below:
3. If you’ve added the Oracle VBox repository, you can directly install the 5.2 release from Synaptic Package Manager or via apt command, after removing the old version.
To add the repository, do:
Open terminal (Ctrl+Alt+T) and run command to add the repository:
sudo sh -c 'echo "deb http://download.virtualbox.org/virtualbox/debian xenial contrib" >> /etc/apt/sources.list.d/virtualbox.list'
Depends your Ubuntu edition, replace xenial (for Ubuntu 16.04) with trusty (for 14.04, Mint 17.x, eOS 0.3), or zesty (for Ubuntu 17.04).
Setup the keyring so to trust the updates from the repository:
