UPDATE 2024: The Focus Indicator is NO Longer available! See the GNOME Discourse page for more about it.

Gnome, the default desktop environment in Ubuntu & Fedora Workstation, is going to replace the app menu with a new window animation, for indicating window focus.

Meaning it will remove the app menu for current window, in the top-bar beside ‘Activities’ button. Because, it’s always confusing users who are new to GNOME.

Gnome to remove app menu, instead using a window animation

Instead, when switching workspaces, closing a window, or pressing Super + Tab, it will perform a short animation on newly focused window. As the GIF below shows you, it’s a window animation that scales up the window and then scales back, indicating that the window is on focus.

The downside so far is that it’s missing the behavior to indicate the process of launching a large or slow application …

How to Install the new Window Animation

The new function is available so far as a Gnome Shell extension called “Focus Indicator“, for testing purpose in GNOME 43. Meaning users of Ubuntu 22.10, Fedora 37, Arch and Manjaro, etc., can try it out by following the steps below.

1. For Ubuntu 22.10, firstly search for and install Extension Manager from Ubuntu Software.

Install Extension Manager in Ubuntu 22.04+

2. Then open the tool, and navigate to ‘Browse’ tab to search and install ‘Focus Indicator’:

For other Linux, just use ON/OFF switch in this web page to install the extension.

Configure the Window Focus animation

After installed the extension, use either Extension Manager or Gnome Extensions app to open the configuration dialog. Then, you can set the scale up/down delay, animation duration, scale factor, and so forth.

For Pinta users who do NOT like the Snap and Flatpak packages that run in sandbox. Here’s how to build the 2.1 release from source tarball in Ubuntu 22.04 & Ubuntu 24.04

Pinta has switch to .NET 6.0 framework since version 2.0, and support .NET 8 via 2.1.2. Which however needs internet connection to fetch something for the first time during the build time. And, most Linux so far still has Pinta v1.x in their system repositories.

Thankfully, building Pinta 2.1 from source is not hard. And, here’s the step by step guide show you how!

1. Firstly, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install .NET 6 as well as dev libraries for building the package.

sudo apt install dotnet-sdk-8.0 debhelper autotools-dev autoconf-archive gettext intltool libgtk-3-dev

2. Next, download the source tarball from github release page (under ‘Assets’ section):

3. Then, extract the tarball in file manager. Right-click on source folder and select “Open in Terminal”.

4. The last step will open a terminal window and automatically navigate to the Pinta source folder as working directory.

In the terminal window, run command to configure the source:

./configure

And, finally compile and install it via:

sudo make install

NOTE: This step needs internet connection if you’re first time using dotnet to build a package. And, it may fail if you’ve ever installed .NET 7.0 but removed (not completely) and use .NET 8.0 now.

If everything’s done without any error, you should now be able to search for and launch Pinta from system start menu (‘Activities’ overview).

Uninstall:

Until you remove the source folder, you can run sudo make uninstall at any time from in that folder to uninstall Pinta package.

If you’ve removed the source folder, re-do the previous steps and replace the last command with sudo make uninstall.

The free and open-source Paint.Net 3.0 clone, Pinta image editor got a new major release after 1 year of development.

The new Pinta 2.1 came with some exciting new features, including WebP image support via webp-pixbuf-loader library, and updated icons with improved support for dark theme and HiDPI displays.

The Gradient tool now has a ‘Transparency Mode‘. The release also adds support for loading files from network drive, meaning user can now open pictures from Google Drive folder.

Other changes in Pinta 2.1 include:

  • Update screenshot tool to make it work in Wayland.
  • Support images with unknown extension but valid contents.
  • Improve canvas rendering performance
  • Improve .ora files support.
  • Update to .NET7, though .NET6 also supported.
  • Various bug-fixes.

How to Install Pinta 2.1 in Ubuntu Linux

Pinta offers official Linux package through both Snap and Flatpak package. Choose either one that you prefer.

NOTE: Both packages now do NOT support for WebP images. Try to build it from source by yourself if you like this feature.

Option 1: Snap package

Ubuntu 20.04 | 22.04 and higher user can easily install the package from Ubuntu Software. NOTE: There are 2 Pinta packages in Software Center, choose the one from Snap Store.

Option 2: Flatpak package

Pinta is also available to install as another universal Flatpak package format. Just press Ctrl+Alt+T on keyboard to open terminal, then run commands below one by one to install it.

  1. First, install the daemon package in case you don’t have it:
    sudo apt install flatpak

    For the old Ubuntu 18.04, add this PPA first before installing Flatpak.

  2. Then, install Pinta as flatpak by running command:
    flatpak install https://dl.flathub.org/repo/appstream/com.github.PintaProject.Pinta.flatpakref

Tip: if you’ve already installed Pinta as Flatpak, run the command below to check updates:

flatpak update com.github.PintaProject.Pinta

Uninstall Pinta:

For the Pinta Snap package, just remove it either using Ubuntu Software app or by running command in a terminal window:

snap remove pina

To remove the Flatpak package, run command:

flatpak uninstall --delete-data com.github.PintaProject.Pinta

Also run flatpak uninstall --unused to remove useless run-time libraries.

Ubuntu by default play a short alert sound when you plug in/out USB drive, power supply, or hit tab function key in terminal.

This is useful for indicating certain type of system messages and events, but it’s easy to mute these type of sounds in case you don’t like them. And, here’s the quick tutorial show you how.

Single command to disable event sound

There’s a dconf database option to toggle on/off this feature for GNOME and Cinnamon desktop.

Simply, press Ctrl+Alt+T key combination on keyboard to open terminal. When it opens, run command:

gsettings set org.gnome.desktop.sound event-sounds false

Not only for Ubuntu, this command should also work for Fedora workstation, Debian, Arch and other Linux with GNOME desktop.

For Linux Mint cinnamon desktop, use the command below instead:

gsettings set org.cinnamon.desktop.sound event-sounds false

Disable event sound via Dconf Editor (graphical way)

In case for those who hate Linux commands, there’s an advanced configuration tool Dconf Editor, that provides a graphical interface to do the job.

1. Firstly, search for and install Dconf Editor from Ubuntu Software (or App Center for 24.04).

2. Then launch Dconf Editor, and navigate to org/gnome/desktop/sounds. Finally, turn off the option for ‘event-sounds’.

Similarly, navigate to org/cinnamon/desktop/sounds or org/mate/desktop/sounds and set the key depends on your desktop environment.

That’s all. Enjoy!

Want to display audio/music visualizer on the desktop? This extension can do the job for Ubuntu 22.10, Fedora 37, Arch/Manjaro Linux with GNOME.

It’s “Sound Visualizer” extension for Gnome Shell based on Gstreamer specially for Wayland. And, it’s working good in my case in Ubuntu 22.04, though it’s said for Gnome v43.

Besides for music playback, it works when any sound play from your computer. And, it has a right-click menu to switch between input/output audio sources. Meaning, it supports sounds input from microphone.

How to Install this “Sound Visualizer” desktop widget

1. (For Ubuntu 22.04 only) As mentioned, the extension supports GNOME v43 at the moment of writing. If you want to try it out in 22.04, first disable extension version validation.

To do so, press Ctrl+Alt+T on keyboard. When it opens, run command (no longer required):

gsettings set org.gnome.shell disable-extension-version-validation true

2. Next, open Ubuntu Software. Search for and install ‘Extension Manager‘ tool for installing and managing Gnome Shell extensions. Or, run command in terminal in case the Software App does not work.

sudo apt install gnome-shell-extension-manager

Install Extension Manager in Ubuntu 22.04+

3. Finally, launch ‘Extension Manager‘, and navigate to ‘Browse‘ tab. Search for and install the ‘Sound Visualizer‘ extension. (For Ubuntu 22.04, just click on Unsupported button)

For Fedora 37, Arch and Manjaro Linux with GNOME, visit this page in web browser and use the ON/OFF switch to install it.

4. After installation, try playing some sounds and see your desktop for the result. To move the widget, you have to temporarily disable “Desktop Icons NG (DING)” under ‘Installed’ tab in Extension Manager.

You can also adjust the visualizer size by opening the extension preferences either via widget’s context menu or by clicking the gear button for that extension in Extension Manager.
