How to Install Shell Configurator:

For Ubuntu 22.04, press Ctrl+Alt+T on keyboard to open terminal and run the command below to install Extension Manager:

sudo apt install gnome-shell-extension-manager

Then, click “Activities” on top bar, search for and open the app:

Finally, navigate to ‘Browse’ tab, search and click install the “Shell Configurator” extension:

To open the settings dialog, switch back to “Installed” tab in Extension Manager and click on the gear button for the extension.

For other Ubuntu edition as well as Fedora, Debian with GNOME, use the on/off switch to install extension in the link page below, after installed the chrome-gnome-shell agent:

sudo apt install chrome-gnome-shell

Have your Ubuntu PC connected with multiple monitors? Here’s how to enable the top bar in all the displays.

In Ubuntu 22.04, you may easily enable the left Dock in all displays via System Settings ->Appearance -> Dock -> show on ‘All Displays’.

However, due to GNOME’s design issue, the top panel only appears in the primary display. So I’m writing this tutorial that could help.

Method 1: Multi Monitors Add-On

There was an extension called “Multi Monitors Add-On” to do the job, which however discontinued. Contributors keep forking the project with new Gnome versions support, and here’s the one for GNOME 42.

NOTE: The extension has an issue in my case that indicators and top-right system menu do not display in external display.

1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to grab the source tarball.

git clone https://github.com/realh/multi-monitors-add-on.git

Install git if you don’t have it via sudo apt install git command.

2. After cloned the source, navigate to the source folder, and install it by copy and pasting to local extension directory.

cd multi-monitors-add-on
cp -r [email protected] ~/.local/share/gnome-shell/extensions/

3. To avoid error in extension manager, disable the version validation check by running command:

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

4. Before being able to enable the extension, you have to restart GNOME Shell. For default session, you need to log out and back in. If you’re running the classic Xorg session, press Alt + F2, type r in pop-up ‘Run a command’ box and hit Enter.

5. Finally, use either Gnome Extensions app or Extension Manager (both available to install in Ubuntu Software) to enable and configure this extension to display top panel on multi-monitors.

Method 2: use dash to panel

If you’re OK to merge the left dock and top-bar into a single panel. The popular “Dash-to-panel” extension can do the job with a simple on/off switch.

Dash to Panel

To install the extension, first press Ctrl+Alt+T on keyboard and run command in pop-up terminal to install ‘Extension Manager’:

sudo apt install gnome-shell-extension-manager

Then search for and launch extension manager in ‘Activities’ overview screen:

Finally, search for and install ‘Dash to panel’ extension from the app window under ‘Browse’ tab.

Once successfully installed the extension, your panels change automatically. And, you can right-click on panel and select the last menu option to open the configuration dialog.

Some applications display notifications in the lock screen, which could be quite annoying!

If you want, you can disable all of them or certain app notifications easily via Gnome Control Center.

1.) Firstly, go to the top-right corner system menu. Then click on “Settings” to open system settings utility, which is also known as gnome control center.

2.) When it opens, navigate to “Notifications” from the left pane. Then, just turn off “Lock Screen Notifications” will disable all the notifications:

3.) For choice, you may scroll down to find out a certain application. Click on it, and toggle the option in the next pop-up dialog.

As you see, there are also options to turn on/off sound alerts, notification bubble, message content in per app basis.

That’s it. Enjoy!

Want to display your computer’s temperature, voltage, fan speed, memory usage, and other system resources usage in top panel? Vitals is a good choice for Ubuntu, Fedora Workstation, and other Linux with GNOME desktop.

It’s a Gnome Shell extension that can display following information on your system tray area:

  • CPU core temerature.
  • Voltage.
  • Fan speed.
  • Memory and Swap usage.
  • Processor load, frequency.
  • System load, uptime.
  • Network speed.
  • Storage usage.

A drop-down menu is available to take a glimpse of all available data. And, user may click on menu option to select which to display on panel.

There are as well bottom buttons to quickly launch system monitor utility and open the extension “Preferences” dialog. In which, you may configure the refresh interval, indicator position, as well as toggle display sensors.

How to Install Vitals Extension:

The extension supports GNOME from version 3.18 to the current 42. Which means, you may install and run it in Ubuntu 18.04, Ubuntu 20.04, Ubuntu 22.04, Fedora 34/35/36, and other Linux (e.g., Debian, Arch, Manjaro) with GNOME.

Method 1: Install the extension via browser

Ubuntu user needs to firstly press Ctrl+Alt+T on keyboard to open terminal. Then, run command to install the agent to install Gnome Extension from web browser.

sudo apt install chrome-gnome-shell

Then, go the link below and turn on the slider icon to install the extension:

Click the link in the page to install browser extension if you don’t see the slider icon, and refresh the page.

Method 2: Install the extension in Ubuntu 22.04 via Extension Manager

Ubuntu 22.04 defaults to Firefox as Snap which does not support installing Gnome Extensions. Besides using another browser or install back the classic .Deb package, “Extension Manager” is a good alternative.

1. Firstly, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install the application:

sudo apt install gnome-shell-extension-manager

2. Next, search for and open the tool from either Activities overview or app grid:

3. Finally, navigate to ‘Browse’ tab in Extension Manager app, search for and install ‘Vitals’ extension:

The indicator should appear immediately on your system panel after installation.

Want to hide the lock screen option from the upper-right corner system menu? Here’s how to do the trick in Ubuntu 22.04 LTS.

For Ubuntu, Fedora and other Linux with GNOME desktop, the screen lock can be disabled either totally or only from the system menu.

Method 1: Single command to disable lock screen

GNOME has a hidden option to disable the lock screen. Simply press “Ctrl+Alt+T” on keyboard to open terminal, then run the command below will do the trick:

gsettings set org.gnome.desktop.lockdown disable-lock-screen true

This command works on Ubuntu 20.04, Ubuntu 22.04, Fedora 35/36, and Debian 11, etc.

NOTE: This command not only hide the menu option, but also completely disable the lock screen function. The Super+L shortcut and automatic screen lock when system idle will no longer work!

For those prefer a graphical configuration tool, this can also be done via “Dconf Editor” tool which is available to install in Ubuntu Software.

To re-enable this feature, open terminal and run command:

gsettings reset org.gnome.desktop.lockdown disable-lock-screen

Method 2: Only hide menu option via Gnome Extension

To just hide the option from system menu, but keep all other ways (e.g, Super+L and idle action) to trigger lock screen, there’s an extension for Ubuntu 22.04, Fedora 36, and other Linux with GNOME 42.

1.) Firstly, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run the command below to install extension manager:

sudo apt install gnome-shell-extension-manager

2.) Next, press Super (Windows) key on keyboard to open “Activities” overview screen, then search for and open the tool:

3.) Finally, search for and install “Hide Lock item in System Menu” extension from Browse tab and done.

For Fedora 36, you may visit the extension web page and turn on the slider icon to install it.
