How to Restore Alphabetical Order of Show Applications App Grid in Ubuntu 22.04

Last updated: August 9, 2022 — 4 Comments

Messed up the app list in ‘Show Applications’ menu in Ubuntu 22.04? It’s easy to restore the original alphabetical ordering.

In Gnome, user can either click the 3×3 9-dots icon on dock or press Super (Windows logo key) + A on keyboard to open the ‘Start Menu’.

The GNOME Desktop ‘Start Menu’

App icons in that menu (definitely screen) support drag and drop re-arranging position. However, there’s no option to restore the app order.

To deal with the issue, user can either use the hidden configuration key or install an extension to do the trick in Ubuntu 22.04.

Option 1: Single command to restore app grid order

Press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command:

gsettings set org.gnome.shell app-picker-layout "[]"

The command set the layout to empty and let it re-generate automatically. However, you need to log-out and back in to apply change.

If you happen to use the classic Xorg session, simply press Alt+F2, type r in pop-up dialog and hit Enter to restart Gnome shell to apply change.

Option 2: Use Alphabetical App Grid Extension:

It’s ‘Alphabetical App Grid‘ which so far supports for GNOME version from 38 to 42. Which means you can install and use the tool to restore app grid in Ubuntu 22.04, Debian 11, Fedora 35/36, Arch Linux and Manjaro etc.

1. For Ubuntu 22.04, firstly search for and install “Extension Manager” from Ubuntu Software.

Install Extension Manager in Ubuntu 22.04

2. Then, search for and open the tool from start menu or ‘Activities’ overview.

3. When the app opens, navigate to ‘Browse’ tab. Finally, search for and install “Alphabetical App Grid” extension.

After installation, it restore the alphabetical ordering automatically. In case you want to drag & drop re-arranging the app icons again, turn the extension off under “Installed” tab. And, re-enable it at any time you want to restore.

In addition, both methods do not restore (remove) the folders that combine multiple app icons in sub-menus. You need to manually drag them out, then use either method above to re-order them.

‘Just Perfection’ Finally Fixed Window Height for Low Resolution Displays

Last updated: August 8, 2022 — Leave a comment

The popular Gnome Extension ‘Just Perfection‘ got an update recently, with love for small displays, e.g., 13 inch laptop with 1366 x 768 screen resolution.

For those never heard of the tool, it’s an extension, with lots of configuration options for customizing your Ubuntu, Fedora, or other Linux’s GNOME desktop appearance.

With it, you can hide the top-bar, the dock, ‘Activities’ button; change the position of clock menu; configure panel height, position (top or bottom), panel icon size, padding; change notification bubble size, location, and much more.

And it supports profiles to quickly switch between your pre-defined layouts and behaviors.

However, the app configuration dialog was always bigger than screen height in my case on 1366×768 laptop screen. I have to press Alt + F7 on keyboard, and move the cursor to move the dialog beyond screen top every time when trying to change something. And, use the shortcut again to move the header bar back in screen.

In the most recent 21.0.0 release, the extension now fixed the issue for GNOME 42 (defaut in Ubuntu 22.04, Fedora 36, and Arch / Manjaro Linux) with small as well as scaled displays.

In addition, this release add options to configure the size of “Alt-Tab” window preview and icon. Toggle display the separator in dock that separate favorite and other opened app icons.

‘Alt-Tab’ Window Preview and Icon size is configurable

And, it allows to change the position of OSD display, such as volume and brightness up/down pop-up, and configure the size of looking glass (GNOME Shell’s integrated debugger and inspector tool).

How to Install ‘Just Perfection’:

To install the extension in Ubuntu 22.04 +, firstly search for and install “Extension Manager” via Ubuntu Software.

Next, open the tool, then search for and install ‘Just Perfection’ under ‘Browse’ tab.

For old Ubuntu and other Linux systems, just turn on the slider icon in the link below:

Install Just Perfection

NOTE: Ubuntu has to first run sudo apt install chrome-gnome-shell in terminal (Ctrl+Alt+T) to install the agent. And, install browser extension if prompted to make the on/off switch visible.

Finally, open the configuration dialog for “Just Perfection”, either via “Extension Manager” or “Gnome Extensions” app, which are available to install in Ubuntu Software/Gnome Software.

Linux Kernel 5.19 was released! Ubuntu Mainline PPA has made the packages for testing purpose.

Linus Torvalds announced this kernel release last night:

On a personal note, the most interesting part here is that I did the release (and am writing this) on an arm64 laptop. It’s something I’ve been waiting for for a _loong_ time, and it’s finally reality, thanks
to the Asahi team. We’ve had arm64 hardware around running Linux for a long time, but none of it has really been usable as a development platform until now.

Linux 5.19 Kernel features initial support for LoongArch CPU architecture, Apple M1 NVMe controller and Apple eFuse driver. There are also initial graphics driver for Raptor Lake P (Intel’s 13th generation processors), In-Field Scan (IFS) to circuit level tests on a CPU core, and bug-fix for Intel laptops running hot and draining the battery faster.

Other features include:

  • Zstd compressed firmware support
  • Google Whiskers Touchpad support.
  • Lenovo X12 trackpoint support.
  • Armv9 Scalable Matrix Extension support
  • Big TCP and pureLiFi’s device driver.

How to Install Kernel 5.19 in Ubuntu 22.04:

NOTE: The mainline kernel packages are NOT officially support! You install them ONLY for specific hardware support or testing purpose!

First, go to the PPA web page via the link button below:

Download Kernel 5.19

Enable Animated Mouse Hover App Icons in Ubuntu 22.04 Dock Panel

Last updated: July 26, 2022 — Leave a comment

For Ubuntu 22.04, there’s now an extension to enable animation when you move mouse pointer over app icons on the left/bottom panel.

It’s a magnifying animation for the dock app icons under mouse cursor. Which, remind me of the old popular Avant Window Navigator.

The extension is called ‘Dash Animator‘ designed for Ubuntu with the default GNOME Desktop. As it requires GNOME 40+, only Ubuntu 22.04 meet the request so far. Though, it should also work on other GNOME based Linux that uses Dash-to-Dock, such as Manjaro Linux.

How to Install the “Dash Animator” Extension in Ubuntu 22.04

1. Firstly, search for and install “Extension Manager” application from Ubuntu Software.

If Ubuntu Software does not work, you may press Ctrl+Alt+T to open terminal, and run the command below to install the tool:

sudo apt install gnome-shell-extension-manager

2. After installed the tool, press Super (the ‘Windows’ logo key) to open Activities overview. Then search for and open it.

3. When it opens, navigate to ‘Browse’ tab, search for “dash to dock animator“, and finally click on “Install” button to install the extension.

Other Linux may simply go to the extension page via the link button below. And, use the ON/OFF switch to install it.

Dash to Dock Animator

Without any configuration, the animation should work immediately after properly installed the extension.

(Optional) To disable or remove the animation, either use Gnome Extensions App or Extension Manager (both available in Ubuntu Software), or turn off the slider in the extension web page (see the button above).

Disable or Remove via Extension Manager

NOTE: removing the extension need restart GNOME (log out and back in) to apply change.

Findex – A Super Fast Tool to Search & Launch Your Apps in Linux

Last updated: July 25, 2022 — Leave a comment

Looking for an alternative app launching tool for your Linux? Findex is one with highly customizable interface and fast performance.

The app runs silently in the background. Once you hit the shortcut key, a search box pop-up in screen center allows to quickly search and open desired applications.

Findex search apps

The tool is super fast as it focuses on performance. It supports fuzzy searching and allows to configure the following things:

  • Search window width.
  • Minimize and maximize window height.
  • Highlight color for match content.
  • Icon size, result size, and shortcut key

How to Get Findex:

The current 0.6.0 release does not work on Wayland session, though it’s said to bring it back in later version. Which means so far, Ubuntu and Fedora need to switch to ‘Ubuntu on Xorg‘ or ‘Gnome on Xorg‘ from the login screen to be able to use the tool.

1. Firstly, download the tarball from the github release page:

Download Findex (tar.gz)

2. Then extract it in file manager. Right-click on generated folder and select ‘Open in Terminal’ to open that folder as working directory in terminal.

3. Finally, run command in terminal to start it:

./findex

Run it first time to verify if it works!

To verify if it works, just press Shift + Space on keyboard. The search box should prompt up allows to type searching your applications.

4. To make Findex runs automatically at startup, run the commands below one by one in the same terminal window:

  • Move the executable file to system path via command: 
    sudo mv findex /usr/bin
  • Move the services file into systemd folder: 
    sudo mv findex*.path findex*.service /etc/systemd/user/
  • Finally, enable the services: 
    systemctl --user enable findex.service
    systemctl --user enable findex-restarter.path

Copy to PATH, and make it auto-start

5. To configure the keyboard shortcut and search appearance, open terminal and run command:

gedit ~/.config/findex/settings.toml

Replace gedit with your system text editor. After saving changes, you need to restart the service by running command: systemctl --user restart findex.service.

Uninstall:

To disable the service, use command:

systemctl --user disable findex.service
systemctl --user disable findex-restarter.path

Then remove the executable file as well as service files:

sudo rm /usr/bin/findex /etc/systemd/user/findex*

Last updated: July 24, 2022 — Leave a comment

For those want to unlock / decrypt PDF files, there’s now a stupid simple graphical tool to do the job in Linux.

It’s easy to encrypt you PDF files in Ubuntu Linux since the built-in LibreOffice office suite has the option on ‘Export as PDF’ dialog. However, there seems no easy way to remove password for PDF file, other than using qpdf command:

It’s so simple that you just need to click ‘Open a File‘ to select your PDF, then type the password, and finally hit ‘Decrypt’. It doesn’t change the original file, but generates a new PDF without password protect.

As the picture shows, it has both light and dark mode that switches automatically according your system color scheme.

NOTE: This app is NOT about to crack password on a PDF file. You need the password to be able to decrypt it.

How to Install unlockR

It is a free open-software software works on both Linux and Windows. For Windows package, just grab the zip from github releases page:

unlockR releases

For Linux, it offers the binary package via universal Flatpak. Ubuntu user need to first press Ctrl+Alt+T on keyboard to open terminal, and run command to install the Flatpak daemon:

sudo apt install flatpak

Next, install the app package via command:

flatpak install https://dl.flathub.org/repo/appstream/com.github.jkotra.unlockr.flatpakref

Like normal applications, search for and open it from ‘Activities’ overview (or start menu) after installation.

Uninstall:

To remove the Flatpak package, open terminal and run command:

flatpak uninstall --delete-data com.github.jkotra.unlockr

You may also clear useless runtime libraries via flatpak uninstall --unused.
