This simple tutorial shows how to apply a blur effect to GNOME Shell UI elements in Ubuntu 20.04 LTS.

Want to enable blur background effect in Gnome? Blyr extension can do the job to the Activities, panel, and app launching screen.

To install the extension, do following steps one by one:

1.) Open terminal by pressing Ctrl+Alt+T on keyboard, then run command:

sudo apt install chrome-gnome-shell

2.) Go to extensions.gnome.org, and click the link to install the browser integration.

3.) Finally go to extensions.gnome.org/extension/1251/blyr/, toggle on and install the extension.

4.) To fix the preferences dialog, open terminal and install required library:

sudo apt install gir1.2-gtkclutter-1.0

When everything’s done, you’re able to control Blur effect via either Gnome Tweaks or Extensions utility.

Gnome’s top bar can auto-hide itself like the left dock panel does via a Gnome Shell extension.

In Ubuntu 18.04, you can enable the feature by installing the gnome shell extension easily from Ubuntu Software.

In Ubuntu 20.04, it’s still easy to install the hide top bar extension, though the Software utility does not longer handle the extension packages.

1.) Press Ctrl+Alt+T on keyboard to open terminal. Then run the apt command to install the extension:

sudo apt install gnome-shell-extension-autohidetopbar

Type user password (no asterisk feedback) for sudo prompt and hit Enter.

2.) Once installed, restart Gnome Shell by pressing Alt+F2 and type r in the pop-up “Run a Command” box and hit Enter.

3.) Finally open either Extensions or Gnome Tweaks (both available to install in Software), and enable “Hide Top Bar” extension.

That’s it. Enjoy!

This is a step by step guide shows how to enable the old Compiz alike Wobbly windows effect in Ubuntu 18.04, Ubuntu 19.10, and Ubuntu 20.04 with default Gnome Desktop.

So far there are two Gnome Shell Extensions that can enable Wobbly Windows effect in Ubuntu:

  • Compiz alike Wobbly Windows Effect: Just do the job.
  • Compiz Wobbly Windows Effect: For those prefer an effect more similar to the original. However, you need to install the libanimation library first.

Preparation:

If you previously installed a Gnome Shell extension, you may skip this step.

1.) Open terminal by pressing Ctrl+Alt+T on keyboard, then run command:

sudo apt install chrome-gnome-shell

2.) Go to extensions.gnome.org, and click the link to install the browser integration.

Install the Gnome Shell Extension:

Do either step 1.) or step 2.) to install one of the two extensions.

Extension 1.) To install the one that simply do the job, go to extensions.gnome.org/extension/2950, and turn on the switch to install the extension.

Wobbly windows effect works immediately after installed this extension.

Extension 2.) If you prefer an effect more similar to the original, do:

  • (You can skip this step as the library now is optional) To make life easier, I’ve uploaded the libanimation library into this PPA repository, open terminal (Ctrl+Alt+T) run following commands one by one to install it:
    sudo add-apt-repository ppa:ubuntuhandbook1/libanimation
    
    sudo apt update
    
    sudo apt install libanimation0 libanimation-glib0 gir1.2-animation-glib-0
  • Then go to the extension web page, and turn on the switch to install it.

Uninstall Wobbly Windows extension:

To remove the extensions, use either Extension utility or Gnome Tweak tool.

To remove libanimation library as well as the PPA, run commands:

sudo add-apt-repository --remove ppa:ubuntuhandbook1/libanimation

sudo apt remove libanimation0 libanimation-glib0 gir1.2-animation-glib-0

Ubuntu 20.04 Gnome 3.36 brings a little change on the top-right corner system tray menu. Log Out, Switch User, Suspend, and Power Off are now sub-menu options of a new ‘Power Off / Log Out‘ button.

For those don’t prefer the new sub-menu, a Gnome Shell Extension is available to bring out the submenu of ‘Power Off / Log Out‘ and rearrange the order of system menu.

1. Open Firefox or Google Chrome and go to https://extensions.gnome.org.

If you’re first time installing a Gnome Shell extension on your system, you may first click the link text “click here to install browser extension” and follow the pop-ups to install the browser extension:

shell browser extension

2. Then open terminal via Ctrl+Alt+T and run command:

sudo apt install chrome-gnome-shell

3. After that, you’re able to install the Gnome Shell extension by going to https://extensions.gnome.org/extension/2917/bring-out-submenu-of-power-offlogout-button/.

If everything’s OK, system tray menu should change. And you can manage the extension either via Extensions utility or Gnome Tweaks.

Ubuntu 20.04 introduces new dark mode in the Settings utility. It is however not full dark when you turn it on in Gnome Shell.

System tray menu, top-bar calendar, notification popups, and desktop context menu are not dark but always light when you switching between light, dark, and standard modes.

Enable Full Dark Theme in Ubuntu 20.04:

1.) First install user themes Gnome Shell extension.

It was able to install the extension simply via Ubuntu Software when I was in Ubuntu 18.04. Ubuntu 20.04 however shows me “No Application Found” when I searching for user themes in the new Ubuntu Software (Snap Store).

  • As a workaround, open Firefox web browser and go to https://extensions.gnome.org:

    Click the link text “click here to install browser extension” and follow the pop-ups to install the browser extension:

    shell browser extension

  • Then open terminal via Ctrl+Alt+T and run command:
    sudo apt install chrome-gnome-shell

  • Finally go to https://extensions.gnome.org/extension/19/user-themes/.

    Turn the switch on and then select install the Gnome Shell extension:

    User Themes extension

2.) Install Gnome Tweaks if you have it.

sudo apt install gnome-tweaks

3.) Finally launch Gnome Tweaks and navigate to Appearance in the left pane, choose Yaru-dark as the Shell theme and done!

And of course select Dark in System Settings -> Appearance to get dark applications if you don’t have it.
