How to Move Clock to the Left or Right Corner in Ubuntu 22.04

Last updated: June 23, 2022 — Leave a comment

For those don’t like to have the ‘date and time’ menu in the center of top panel, here’s how to move it to either left or right in Ubuntu 22.04 LTS.

Ubuntu, definitely the GNOME desktop, does not have option to configure the clock menu position. But, there are a few extensions can do the job. And, here I’m going to show you how to install and use them.

Tip: Extensions introduced in this tutorial should work on all Linux uses GNOME 42, e.g, Fedora 36, Arch Linux, Manjaro.

Step 1: Enable ability to install Gnome Extensions

Usually, we install Gnome shell extensions by visiting extensions.gnome.org and use the ON/OFF switch to install or remove an extension. Since Ubuntu 22.04, there’s also an “Extension Manager” app is available in system repository to make life easy.

Option 1: Prepare for installing extension through web browser

NOTE: the pre-installed Firefox in Ubuntu 22.04 is a snap package, which so far does not support this thing. You may either use another browser and go “Option 2”.

Press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install the agent to enable the ability to install Gnome Extension via browser, and the app for managing them.

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

For the first time, you need to go to exensions.gnome.org and follow the “Click here to install browser extension” link to install the browser extension.

Option 2: Install Extension Manager

The Extension Manager app allows to search for, install, and manage extensions all in one. To install it in Ubuntu 22.04, press Ctrl+Alt+T on keyboard to open terminal and run command:

sudo apt install gnome-shell-extension-manager

After that, click on top left “Activities”, then search for and open the app to get start.

Step 2: Select install Extension to move Clock

There are a few extensions can do the trick in GNOME. Choose one from the options below that you prefer!

Option 1: Just Perfection

This is a tweak tool to customize GNOME Shell, change the behavior and disable UI elements. They provides many useful toggle options, including moving the clock menu position.

To install the extension, either search for and click install it via “Extension Manager”:

Or, use the ON/OFF switch by visiting the web page below in your browser:

Just Perfection Extension page

After installed it, open its ‘settings’ dialog either via “Extension Manager” under Installed tab or use “Gnome Extensions” app. Scroll down, and you’ll find the option to move clock position via “Customize” tab.

Option 2: Left Clock or Sur Clock

Just Perfection is a bit heavy if you don’t need the other options. There are a few other extensions that designed specially for moving clock position:

“Clock Left” or “Left Clock” – Move clock to left and replace “Activities”.
Sur Clock – Move clock to left or right via preference option.

To install one of the extension, simply search for and click install in “Extension Manager”:

Or, use the ON/OFF switch in the link page to install: sur clock, left clock, and clock left.

Option 3: Top Bar Organizer

NONE of the previous extensions will move clock to far right corner. If you insist, try “Top Bar Organizer”.

This extension is designed to organize all items on top-bar. It was created for GNOME 40, but no longer updated!! However, it works on current GNOME 42 desktop with few tweak.

1.) First, press Ctrl+Alt+T on keyboard to open terminal. And, run command to disable version validation, since it does not support Ubuntu 22.04:

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

2.) Then, either search for and install it in “Extension Manager”:

Or, turn on the slider icon in the link page below to install it from web browser:

Install Top Bar Organizer

3.) The Extension preference does not work for GNOME 42. However, the dconf editor options do work.
First, run command to install dconf editor:

sudo apt install dconf-editor

Then, search for and launch “Dconf Editor” from the overview screen. And, navigate to org/gnome/shell/extensions/top-bar-organizer.

To make clock menu show in right corner, write ‘dateMenu‘ as value of right-box-order. And, put it to the end for far right.

NOTE: The change will persist even after removed the extension. To restore, erase the keys in Dconf Editor and restart GNOME Shell (log out and back in)

There are quite a few audio tag editing applications for Linux. Tagger is a new one with modern GTK4 user interface.

Kid3, puddletag, and easytag editors are really good. But for GNOME (the default desktop environment for Ubuntu, Fedora Workstation), Tagger looks more native due to GTK4 and libadwaita.

How to Enable Top Panel on Multiple Monitors in Ubuntu 22.04

Last updated: June 16, 2022 — 2 Comments

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 multi-monitors-add-on@spin83 ~/.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.
