This simple tutorial shows how to add a “Show Desktop” icon to the top panel in Ubuntu 22.04 and Ubuntu 24.04 with default Wayland session.
I’ve written about how to add ‘Show Desktop’ to the left dock panel, however, it works for the class Xorg session only. Since 22.04, Ubuntu switched to Wayland as its default display server. If you switched back to Xorg (via the gear icon in login screen), then this tutorial still works.
For GNOME (the default desktop) on Wayland, the thing can be done via a simple extension. And, here’s how to do it step by step.
Step 1: Install Extension Manager
Ubuntu has an “Extension Manager” tool in system repository, which allows to easily install and manage Gnome Shell extensions.
First, search for and install the tool from either Ubuntu Software or App Center, depends on your Ubuntu edition.
Install Extension Manager in Ubuntu Software/App Center
Or, press Ctrl+Alt+T on keyboard to open terminal, and run single command to install the tool:
sudo apt install gnome-shell-extension-manager
Step 2: Install the ‘Show Desktop’ button extension
After installing the Extension Manager, search for and launch it from the overview screen.
When the tool opens, navigate to ‘Browse’ tab, finally search and install the “Show Desktop Button” extension.
A ‘Home’ icon should appear immediately on the top-panel after installed the extension. By clicking on it, will hide (or show) all open app windows.
For choice, you can switch back “Installed” tab in Extension Manager, and open the preferences dialog for the extension. In which, you can choose to place the ‘Show Desktop’ icon in left, far left, center, right, or far right corner.
In addition, you may also install “Just Perfection” extension using Extension Manager. Which provides an Panel Button Padding Size option under Customize tab, to make the top-right panel icons look more compact.
For those who prefer the new ‘App Center’ in Ubuntu 23.10 and Ubuntu 24.04, it’s easy to install it in Ubuntu 22.04 and here’s how!
The new App Center is also the snap-store but re-built with Google’s Flutter UI toolkit. It’s fast and always works!
With it, the software app will never stuck at “Downloading Software catalog” or the spinning loading circle.
The App Center supports both Snap and native Debian (.deb) packages in Ubuntu 23.10/24.04, however, in my tests, searching Debian package always show me “No results found” in 22.04. If you know how to fix the issue, please leave a comment here.

How to Install the new App Center in Ubuntu 22.04
NOTE: The NEW App Center so far lacks ability to install local .deb package!!
1. First, press Ctrl+Alt+T on keyboard to open a terminal window. When it opens, run command:
This command may fail and output something look like: snap ‘snap-store’ has running apps, pids: 2205. In the case, just kill snap-store using the ID number (replace 2205 to yours):
sudo kill -9 2205
Then, re-run the snap refresh command.
2. After that, just press Super (windows logo) key to open overview screen, search and launch “App Center”.
How to Restore
To revert back the previous ‘Ubuntu Software’, also press Ctrl+Alt+T on keyboard to open terminal and run command:
For those who prefer the old system font, now it’s easy to get it in Ubuntu 23.10 via a new package!
Since Ubuntu 23.04, Ubuntu takes use a new slim font for the text in system menus, documents, and app windows.
Some users do NOT like the change, because the new font is thin and hard to focus on. And, I’ve written about how to get the previous font back in Ubuntu 23.04.
Now, Ubuntu 23.10 includes a new package fonts-ubuntu-classic in system repository. Make it easy to do the job even without a system restart.
Install the Classic Font in Ubuntu 23.10
To install the font, simply press Ctrl+Alt+T on keyboard to open terminal.
When terminal opens, run command:
sudo apt install fonts-ubuntu-classic
Run sudo apt update to update package cache if it says package not found.
After installation, your system font change without restart! For opened app windows, you need to close and re-open them. For ‘Files’, just run nautilus -q to reload.
(Optional) Install ‘fonts-ubuntu-console’
The package above does not install the old font for the command console.
For choice, you may download the package for Ubuntu 22.04:
This simple tutorial shows how to reset Ubuntu Dock, the left panel, to its original status in Ubuntu 22.04 & Ubuntu 23.10.
As you may know, Ubuntu Dock (aka Dash-to-Dock) is an extension to the GNOME Desktop. It has many configure options, however most of them are hidden.
In Ubuntu 23.10, it finally provides a preference dialog to configure its appearance with full options. See HERE for how to get it.
Ubuntu Dock preference dialog
The preference dialog so far does not have ‘Reset’ buttons. If you messed thing up or want to restore Ubuntu Dock to factory setting, then this tutorial may help!
Reset Ubuntu Dock
The steps below should work in all current Ubuntu releases, include other Gnome-based Linux (such as Manjaro) using Dash-to-dock extension.
Option 1: Single command to reset Ubuntu Dock
Without installing anything, running a single command in terminal window can do the job.
First, open terminal either by searching from the overview screen, or by pressing Ctrl+Alt+T shortcut key on keyboard.
When terminal opens, copy and paste the command below and hit Enter.
The command above resets Ubuntu Dock, but leaves your favorite apps (pinned app icons) unchanged.
If you want to also reset the app icons on the Dock, run command:
gsettings reset org.gnome.shell favorite-apps
Option 2: Use Dconf Editor (graphical way)
For a graphical way, the advanced ‘Dconf Editor’ configuration tool can do the job.
First, either search for and install ‘Dconf Editor‘ from Ubuntu Software:
Or, install it by running a command in terminal:
sudo apt install dconf-editor
Then, launch Dconf Editor by searching from the overview screen.
When it opens, navigate to ‘org/gnome/shell/extensions/dash-to-dock‘. Finally, click on ‘≡’ menu, select “Reset visible keys“, and click “Apply” button in bottom.
To reset the app icons, go to ‘org/gnome/shell/favorite-apps‘, turn on “Use default value” and finally click Apply.
For best integration, the LibreOffice PPA is finally updated with the LibreOffice 7.6.x packages for Ubuntu.
LibreOffice 7.6 was released almost one months ago. It features document themes support, zoom gestures in the main view, new “Page Number Wizard” dialog for Writer, new compact layout for pivot tables in Calc, and various other changes. See release note for details.
LibreOffice provides official packages through Flatpak in Flathub.org, Snap in Ubuntu Software. However, both run in sandbox. It also provides official .deb packages, which are however build against a very old baseline for maximum compatibility.
For those hate the office suite run in sandbox, the LibreOffice PPA maintained by Ubuntu members is the best choice. Though, it always has quite a few or even weeks delay for the new major release packages. And, LibreOffice 7.6 is finally available via the PPA, after almost 4 weeks by releasing the first point 7.6.1 version.
Install LibreOffice 7.6 (7.6.1 so far) in Ubuntu via PPA
1. First, press Ctrl+Alt+T on keyboard to open a terminal window. When terminal opens, run command to add the PPA:

2. After adding the PPA, just search for and launch “Software Updater” (or Update Manager), then update the packages from the pre-installed office suite.
Or, run the command below in terminal instead:
sudo apt install libreoffice
Linux Mint needs to run sudo apt update first to update package index first.
Uninstall/Restore
To uninstall the packages, just purge the PPA, which will also downgrade LibreOffice to the original pre-installed versions depend on your Ubuntu edition.
To do so, open terminal (Ctrl+Alt+T) and run commands:
Have many extensions installed on your GNOME desktop? Here’s a new tool to help managing them with a more efficient way.
Without launching Gnome Extensions app or Extension Manager every time, the new “Glass Grid” allows user to either press a keyboard shortcut or click the indicator on panel to quickly trigger an overview of all the installed extensions.
Then, user can either click on extension name to open its preference dialog. Or, use the buttons right beside them to turn on/off, refresh or configure extensions. There’s also a global ON/OFF switch in top-right to toggle all extension with one click. If you have too many extensions more than a page capacity, it supports scrolling horizontally with either mouse or keyboard arrow keys.
The extension grid view can be triggered either via keyboard shortcut or indicator applet. And, it will disappear when pressing Esc or clicking anywhere outside. It has a dark mode layout, and support quick launching extensions.gnome.org and Gnome Extensions app (if installed) via header buttons.

This simple tutorial shows how to install the latest Firefox Nightly in all current Ubuntu releases!
Firefox Nightly is the bleeding edge version of the web browser that updates twice a day. It contains features that are still in developments months or even years before they become mainstream.
The Nightly build is more likely to crash than the stable release. For testing purpose or power-user who prefer the very latest features, here you can install Firefox Nightly via 3 ways!
Method 1: Install Firefox Nightly via Snap package
The easiest way to get Firefox Nightly is using the Snap package. It receives updates automatically, however, will override the pre-installed Firefox, by updating it to the latest edge channel.
Ubuntu 22.04 and higher users, can simply open Ubuntu Software (or App Center). Search Firefox and switch channel/source to “latest/edge”.
Or, press Ctrl+Alt+T on keyboard to open terminal. When terminal opens, run the command below instead to install Firefox Nightly:
snap refresh firefox --channel=latest/edge
NOTE: The Snap package will take use the previous profile. In the case, you can open about:profiles page, then create a new profile and set it as default.
Method 2: Use New Apt Repository
Mozilla announced new official apt repository recently. It contains the .deb package of most recent Firefox Nightly package for all current Ubuntu and Debian releases.
1. First, press Ctrl+Alt+T on keyboard to open terminal. When terminal opens, run command to download & install the key for that repository:
2. Next, add the apt repository by running the single command below:
echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.gpg] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null
This command will create the ‘mozilla.list‘ file under /etc/apt/sources.list.d directory and write the source line into it.
3. Finally, refresh the system package cache:
sudo apt update
And, install the Nightly build of Firefox from that repository by running command:
sudo apt install firefox-nightly
Method 3: Install Firefox Nightly via Ubuntu PPA
For choice, there’ a daily build PPA maintained by Ubuntu members. Which, so far supports Ubuntu 20.04, Ubuntu 22.04, Ubuntu 23.10, and Ubuntu 24.04
The PPA is a good choice, since it contains native .deb package. It will NOT override any other Firefox Stable package (neither deb nor snap), and uses its own profile for storing user data.
1. To add the PPA, first press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command:
Type user password (no asterisk feedback) when it asks and hit Enter to continue.
2. Linux Mint user needs to manually update the system package cache after adding PPA, though its done automatically in Ubuntu 20.04 and higher:
sudo apt update
3. Finally, install the Firefox Nightly build by running command:
sudo apt install firefox-trunk
After installing the package, launch it from ‘Activities’ overview screen or app menu depends on your desktop environments. And, you can use “Software Updater” (or Update Manager) every day to keep the package up-to-date.
Uninstall Firefox Nightly
For the Snap package, just open terminal and run command will restore to the pre-installed Firefox package:
snap refresh firefox --channel=latest/stable
However, the restored Firefox Snap will create a new user profile instead of using the original one, though you can manually backup and restore your important data.
For the apt repository package, open terminal (Ctrl+Alt+T) and run command to remove it:
sudo apt remove --autoremove firefox-nightly
To remove the source repository, just delete the source file and key by running the 2 commands below one by one:
