Ubuntu by default shows orange dots under app icons in the dock panel, indicate the apps have running windows. They are called ‘running dots‘. And, Ubuntu provides hidden settings to change the style as well as colors if you don’t like the default look and feel.

Option 1: Change the Orange Dots via Dconf Editor

1.) The advanced ‘Dconf Editor‘ provides a graphical interface to configure hidden settings in Ubuntu. You may firstly install it either via the apt command below:

sudo apt install dconf-editor

or use Ubuntu Software:

2.) Next, search for and open ‘Dconf Editor’ from the Activities overview screen. When it opens, navigate to ‘/org/gnome/shell/extensions/dash-to-dock/‘.

3.) Scroll down, find out and click to configure the key ‘running-indicator-style‘. By selecting another value will replace the dots with dashes, square dots, or lines.

4. After changing the style, you may also specify another color, by changing the value of ‘custom-theme-running-dots-color‘:

As you see, it also supports border color though disabled by default since border width set to 0.

In addition, you may enable different colors for running dots (dashes or lines) on per app basis by disabling ‘custom-theme-customize-running-dots‘ and then enabling ‘running-indicator-dominant-color.

Option 2: Customize the Orange Dots via gsettings command:

For those familiar with Linux commands, the previous things can be done by running the commands below in terminal.

Firstly, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run the commands below accordingly.

1.) Replace the dots with square dots, dashes, or vertical lines by running command:

gsettings set org.gnome.shell.extensions.dash-to-dock running-indicator-style 'DASHES'

Here the value ‘DASHES’ can be replaced with: ‘DOTS’, ‘SQUARES’, ‘SOLID’, ‘METRO’, ‘CILIORA’, and ‘SAGMENTED’.

Also, set it to ‘DEFAULT’ will reset to default and override the settings below.

2.) Specify a color to use for ‘running dots’ (change the color value as you prefer):

gsettings set org.gnome.shell.extensions.dash-to-dock custom-theme-running-dots-color '#F2F1F0'

3.) To have color on per app basis, first disable ‘custom-theme-customize-running-dots’ key via:

gsettings set org.gnome.shell.extensions.dash-to-dock custom-theme-customize-running-dots false

then enable ‘running-indicator-dominant-color’ via command:

gsettings set org.gnome.shell.extensions.dash-to-dock running-indicator-dominant-color true

That’s all. Enjoy!

Want to display your avatar icon in the top-right corner system menu? Here’s an extension to do the job for Ubuntu 20.04, Ubuntu 21.10, and Debian 11 with GNOME desktop.

You know, many Linux desktops (e.g., KDE Plasma and Cinnamon) display the icon/figure of user account in the system start menu.

GNOME however does not have the classic style ‘start menu’ by default. Instead, user may add the avatar icon into upper-right corner system tray drop-down menu (aka system menu).

Install Avatar Extension:

The function is implemented by a small extension called ‘Big Avatar‘. It so far supports GNOME version from v3.36 to 40.

1. Install ‘chrome-gnome-shell’

Firstly, make sure you have installed the chrome-gnome-shell package, which is required for installing Gnome Extensions in Ubuntu from web browser.

To install it as well as extension management tool, press Ctrl+Alt+T on keyboard to open terminal. Then, run command:

sudo apt install chrome-gnome-shell gnome-shell-extension-prefs

2. Install Big Avatar Extension:

NOTE: Firefox as Snap (pre-installed in Ubuntu 21.10) so far (Feb, 2022) does not support for installing Gnome Extensions! Use another browser or install Firefox as classic DEB.

Now, go to the link button below in web browser and turn on the toggle icon to install the extension:

If you don’t see the toggle icon, try installing browser extension via ‘Click here to install browser extension’ link and refresh the web page.

shell browser extension

3. Configure Avatar icon size:

The icon should appear immediately after installation. However, the icon size is NOT looking good.

To adjust it, search for and open ‘Gnome Extensions‘ app from Activities overview screen. When it opens, click on the gear button and change the value accordingly.

That’s all. Enjoy!

After Python3 and PyQt5 port, the Puddletag audio tag editor finally got a new update after almost 1 year and half of development.

Puddletag 2.1.0 fixed many crash issues, including crashes when using Update From Tag function, mass tagging search button, adding custom tag with language lyrics, searching with AcoustId, specifying ‘Export artwork to file’ in action, and more!!

Besides, there are some minor new features. When refreshing in preview mode, it now asks confirm before discarding changes; New Actions menu option ‘Go to parent folder‘; Copy & Paste cover from/to clipboard.

How to Install Puddletag 2.1.0 in Ubuntu

The new 2.1.0 release updates the minimum core dependency libraries! It seems that system default libraries in current Ubuntu releases (at least Ubuntu 20.04) do NOT meet the requirements.

Fortunately, Puddletag now is available to install via PyPI repository. Which means, all Ubuntu editions (including Ubuntu 18.04) as well as Ubuntu/Debian based systems may install the latest package via following steps!

1. Remove old package:

If you have an old puddletag package installed, such as from PPA repository. Remove it first by running command in terminal (Ctrl+Alt+T):

sudo apt remove --autoremove puddletag

2. Install Pip:

In case you don’t have pip, the command line tool for installing and managing Python packages. Firstly, press Ctrl+Alt+T on keyboard to open terminal. And, run command to install it:

sudo apt install python3-pip

Type user password (no visual feedback) for sudo authentication and hit enter.

For non-Ubuntu/Debian based systems, replace the apt command with your system package manager.

3. Install Puddletag from PyPI:

Finally, run this single command in terminal will download & install the latest Puddletag as well as dependency packages from PyPI:

pip3 install puddletag

Later, you may run the command below at any time to try upgrading the package:

pip install --upgrade puddletag

Finally, try launching puddletag via command:

~/.local/bin/puddletag

4. Fix app shortcut issue:

By default, pip installs the executable file into ‘.local/bin‘ directory. If it’s NOT in your PATH, then Puddletag icon won’t show in app launcher (Activities overview search result). To workaround this issue, do following steps:

a.) Add ‘.local/bin’ to the PATH.

Firstly, open a terminal window and run the command below to edit user profile:

gedit ~/.profile

When the file opens, add following lines and save it:

if [ -d "$HOME/.local/bin" ] ; then
    PATH="$HOME/.local/bin:$PATH"
fi

After log out and back in, puddletag should appear in app menu (or overview search result).

b.) Fix missing icon file.

After step a.), the app shows in app launcher but misses icon. To fix the issue, simply grab one from the web. For example, download the source tarball and extract the PNG file.

Then put the icon file (named puddletag.png or puddletag.svg) into “.local/share/icons” directory. It’s a hidden folder, press Ctrl+H to toggle display it in file manager.

Manually install missing icon file

How to Remove Puddletag Python Package:

To remove Puddletag via pip, simply run command:

pip3 uninstall puddletag

However, this command leaves useless dependency packages un-handled. To also remove the dependency libraries, install pip-autoremove tool:

pip3 install pip-autoremove

Then use the tool to remove puddletag as well as dependencies:

pip-autoremove puddletag

And, finally remove pip-autoremove if you want:

pip3 uninstall pip-autoremove

That’s all. Enjoy!
