Archives For Gnome Shell

The popular Gnome 3 desktop session for Linux. Available in Ubuntu Software Center.

Gnome Tweaks, one of the must have apps for configuring Ubuntu, removes GNOME Shell Extensions support by releasing version 40.

Which means in next Ubuntu release which will ship with Gnome 40+, you have to use another tool to manage Gnome Shell Extensions.

If you have tried out Fedora 34, you should already see the prompt at first launch of Gnome Tweaks: “Extensions management has been moved to GNOME Extensions”.

The “new” tool “GNOME Extensions” is available in Ubuntu universe repositories since Ubuntu 20.04 LTS. If you don’t have it, open terminal by pressing Ctrl+Alt+T on keyboard, and run command to install it:

sudo apt install gnome-shell-extension-prefs

Then you can open it from system app launcher.

Different to the extensions tab in Gnome Tweaks, the GNOME Extensions tool displays built-in Gnome Shell extensions and user installed extensions separately.

Besides the slider icons to toggle on/off extensions and gear buttons to change extension settings, there’s a triangle icon after each extension. Clicking on the icon will expand the extension with a brief description as well as the website and remove buttons.

In addition, Fedora users can get the tool by installing gnome-extensions-app package. Other Linux with Gnome Desktop can install the flatpak package.

Looking a graphical tool to manage users and groups in Ubuntu Desktop? Try the classic Gnome user settings tool.

A user is anyone who uses a computer, and users may be grouped together into a “group”. Users and groups are used to control access to the system’s files, directories, and peripherals.

For those hate Linux commands, the classic GUI tool, which was default in Ubuntu when it was Gnome 2, allows to add, remove, edit users and groups.

Like system default User Settings, it offers options to add, remove, and edit all user accounts. Though there are a few differences:

  • It can generate random password for user account.
  • Automatic login option seems not working.
  • Custom user privileges under Advanced Settings.

By clicking on “Manage Groups” button, you can then add, remove, edit groups.

To add or remove a user from a group, simply go to group properties, and check or un-check the user name under Group Numbers.

To install the GUI user and group managing tool, open terminal from system app launcher and run command:

sudo apt install gnome-system-tools

Then search for and open “Users and Groups” from system app launcher and enjoy!

Run Ubuntu or other Linux with Gnome Desktop on E-Ink Displays? There’s now an E-Ink Mode Gnome Shell extension allows to easily toggle desktop appearance suitable for the monitors.

  • Switch shell theme to built-in light high contrast one (User Themes extension is not required).
  • Switch GTK and icon theme to High Contrast
  • Switch Cursor theme to DMZ-White
  • Disable shell animations
  • Restore previous themes and animation settings when disable this extension

Though the things can be done manually step by step, the extension make it as easy as a toggle switch in Extensions tool. And so far Gnome 3.36 is supported.
