Want to hear your sound in microphone? Here’s a stupid simple tool to the job in Linux.

It’s Whisper, a new free and open-source GTK4 application, allowing listen to microphone through your speaker. Which, is useful for testing your microphone or for listening to your voice.

As the screenshot shows, the app is quite easy to use. Just select the microphone and speaker from the list, and click ‘Connect’. Then, you can say something or make some noise through microphone to see the magic.

As a GTK4 application, it follow system color scheme by switching between light and dark automatically. However, it needs both PulseAudio and Pipewire to make things work, which is default in Pop! OS 22.04, Ubuntu 22.10, Ubuntu 23.04, Fedora 35/36/37, etc.

How to Install Whisper in your Linux

As mentioned above, this application requires Pipewire audio server. For current Ubuntu 22.04 LTS, it’s NOT the default, though you can enable it by following this tutorial (NOT recommend for beginners).

Whisper is available to install as universal Flatpak package. You can install it by following the steps below one by one:

1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install Flatpak daemon:

sudo apt install flatpak

Other Linux can follow this setup guide to enable Flatpak support.

2. Then, run command to install Whisper as Flatpak package:

flatpak install https://dl.flathub.org/repo/appstream/it.mijorus.whisper.flatpakref

3. After installation, search for and launch it from start menu (Show Applications) like normal app and enjoy!

How to Remove Whisper

To remove the software package, also open a terminal window and run command:

flatpak uninstall --delete-data it.mijorus.whisper

Also run flatpak uninstall --unused to remove useless runtime libraries.

This simple tutorial shows how to easily check your SSD health in Ubuntu and/or Linux Mint desktop.

I’ve been running Ubuntu Linux on my old laptop for about 7 years. Everything works well, but it recently refuses to boot sometimes when pressing on the physical power button. Not sure what’s the problem, but I guess it’s something to do the data reading issue from SSD drive.

In Windows 10, I prefer to use CrystalDiskInfo which is super easy to understand for beginners. For Linux, there’s a tool GSmartControl available for choice.

1. First, the tool is available in most Linux’s system repositories. User can just search for and install it from system package manager. For Ubuntu, it’s available to install via Ubuntu Software app:

For those familiar with Linux command can run a single command in terminal (Ctrl+Alt+T) to install it:

sudo apt install gsmartcontrol

2. After that, search for and launch it from start menu (or Activities overview). It will list your SSD drive in the app window.

By double-clicking on the disk icon or go menu “Device -> View Details” will open the information dialog that you need.

Things are not so easy to read for beginners. But it will highlight something that is not going well with red text font or background.

By moving mouse cursor over any item in the app window, there will be a tool-tip pop-over that explain with detailed information. As the screenshot below shows, it shows you:

  • power-on time.
  • total disk read and write.
  • read error rate.
  • temperature and other information.

For those prefer a percentage value of the device life, go “Statistics” tab and check the value of Percentage Used Endurance Indicator. In my case as the screenshot shows, there should be still 93% left.

And you can click on “View Output” button to view all the info as text, copy and paste them into online forums to ask for help! Or, run a “Self-Tests” manually to see if there’s any error.

Then, run regular updates via Software Updater (Update Manager) app will update the pre-installed LibreOffice packages to the latest!

Option 2: Snap package

Snap is an universal package runs in sandbox. Ubuntu 20.04 and higher can easily search for and install LibreOffice as Snap from Ubuntu Software.

It will remove the PPA repository and downgrade the office suite to the pre-installed version.

For the Flatpak package, run the command below to remove it:

flatpak uninstall --delete-data org.libreoffice.LibreOffice

For other two, either uninstall via Ubuntu Software or just remove the package file.
