For people who are hard-of-hearing, and/or for better understanding audio, here’s a live captions app that provides real-time automatic subtitles on Linux desktop.
The app displays a wide flat window on desktop, showing real-time (may have few hundred milliseconds delay) subtitles for voice come from either speaker or microphone.
It’s free and open-source, and captioning locally without network permission with the power of deep learning. And, there’s no API keys, no proprietary services/libraries, no telemetry, no spying, no data collection.
The only thing you need is a somewhat-decent CPU that can perform real-time captioning. It’s tested and working good in my i5-10400, and following CPUs mentioned in project page:
Intel i7-2670QM
Intel i7-7820HQ
Intel i5-8265U
AMD Ryzen 5 1600
Steam Deck
How to Install the Live Captions app
The Live Captions app is available as Flatpak package that works in most Linux desktop!
Linux Mint 21 and Fedora 38+ (with 3rd party repository enabled) can directly search for and install “Live Captions” from either Software Manager or Gnome Software.
1. For Ubuntu, first press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to enable flatpak support:
sudo apt install flatpak
Other Linux can follow this official setup guide to enable Flatpak.
2. Then, run command to install the app through Flatpak package:
As running in sandbox, it may have hundred MB downloads for run-time libraries.
After installation, launch it from start menu or ‘Activities’ overview depends on your desktop environment.
If you’re first time installing an app through Flatpak, then you may need to log out and back in to make app icon visible. Or, run command below to start it from terminal:
flatpak run net.sapples.LiveCaptions
Start Live Captions
The first launch of the app will guide you to perform a short benchmark for your CPU. You need at least 1.0 score for running this app.
As it noticed, the live captions may not be accurate. It may make mistakes, including when it comes to numbers. Please do not rely on the results for anything critical or important.
When done, it starts into a blank window. There click the gear button to open ‘Preferences dialog’ to configure the window width, background opacity, text font, etc.
The built-in model so far support only English. Though, there are few more models available to download, which makes it work for Polish and French language.
To make the window always on top, just right-click on it and click “Always on Top” option.
When done configuration, just start live chat, or play something with voice, the app window should automatically show you the real-time subtitles in few seconds.
This simple tutorial shows how to edit .desktop files, the config files for your apps shown in start menu (app launcher), in Linux via single command.
In most Linux, the app icons (and their names) you see in dock & launcher are handled by .desktop files. If need, user can edit them by using either text editor or even third-party apps.
For software developing, scripting, or editing multiple .desktop files at the same time, there’s a command line tool that can help!
What you can do by editing .desktop file for your app:
The .desktop files are usually stored in following locations:
/usr/share/applications – for system wide.
$HOME/.local/share/applications – for current user only.
/var/lib/flatpak/exports/share/applications – for Flatpak apps (system wide).
$HOME/.local/share/flatpak/exports/share/applications – for Flatpak apps (current user).
/var/lib/snapd/desktop/applications/ – for Snap apps.
By editing a .desktop file that is associated with your app can do following things:
Change app icon
Change the app name in start menu.
Hide app
Group app icon in different categories.
Associate with different file types.
And more.
Find out the .desktop file for your app
If you don’t know where is the .desktop file, then try following steps to find it out.
First, open terminal (Ctrl+Alt+T) and run command to install plocate (or mlocate for old Ubuntu):
sudo apt install plocate
Then, update the database by running command:
sudo updatedb
Finally, try searching the desktop file for your apps (Firefox for example):
locate "*firefox*desktop"
In last command replace firefox with the keyword for yours (case sensitive). And, copy the path-to-file for the one in the location mentioned above.
Single command to edit the .desktop file
As far as I know, Debian, Ubuntu, Fedora, Manjaro, and their based systems have desktop-file-edit tool out-of-the-box for edit .desktop entries.
For example, hide all the Waydroid Android app icons associated with the .desktop files under .local/share/applications directory.
for file in $Home/.local/share/applications/waydroid.*.desktop; do desktop-file-edit --set-key=NoDisplay --set-value=true $file; done
In addition, the desktop-file-edit command will automatically validate the .desktop file after done editing it. It will output errors if validation not passed. For more, see its man page.
This simple tutorial shows how to install the latest Android Studio (2025.2.1 updated) in Ubuntu 22.04 and/or Ubuntu 24.04.
Android Studio, the official IDE for Android app development, is easy to install in Ubuntu in different ways! They include Snap, Flatpak, and official tarball.
NOTE: All the Android Studio packages below support only amd64 (Intel/AMD) CPU architecture type.
Method 1: Install Android Studio via Snap package
The easiest way to install the IDE is using the Snap package, which however runs in sandbox environment. At the moment of writing, the Snap package is at version 2025.1.3, though the newer 2025.2.1 is in dev channel now. Just install it and wait, it will automatically update to the latest once published.
Simply launch App Center (or Ubuntu Software for 22.04), then search & install Android Studio:
This is beginner’s guide shows how to install and setup Waydroid to run full Android system as well as Android applications in Ubuntu.
I’ve written about this by using Anbox, which is however no longer in active development.
This is a re-write with free and open-source ‘Waydroid’, which is a container-based approach to run a minimal customized Android system image based on LineageOS.
Android OS in my Ubuntu 22.04 desktop
This tutorial is tested and works on Ubuntu 22.04 and Ubuntu 24.04 LTS with default Wayland session (Xorg is NOT supported)! It should also work in Debian Bookworm, Trixie, and Sid.
Hardware specs include:
CPU: Intel i5-10400.
GPU: Intel HD 630.
Step 1: Install Waydroid
Waydroid is easy to install in Ubuntu/Debian based systems, through its official apt repository.
1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install required packages:
sudo apt install curl ca-certificates
sudo command needs password authentication, but with no asterisk feedback. Just type in mind and hit Enter.
2. Then, run command to download the official script, and run it to add Waydroid repository into your system.
curl https://repo.waydro.id | sudo bash
In case the script does not work properly, find out your OS code manually via either lsb_release -sc or cat /etc/os-release command. Then, run command below instead:
curl https://repo.waydro.id | sudo bash -s jammy
Replace jammy depends on your system code-name. So far, it supports focal, jammy, noble, bookworm, bullseye, sid
3. Finally, run command to install Waydroid:
sudo apt install waydroid
Try sudo apt update first to refresh cache if the command output package not found
Once successfully installed the app, you should be able to launch it from start menu, applications menu, or any other app launcher depends on your desktop environment.
Step 2: Initialize
The first launch of the app, will launch the “Initialize Waydroid” dialog. If it somehow does not launch, try running waydroid first-launch command in terminal (Ctrl+Alt+T) to see what’s going wrong.
NOTE: Non-default Kernels (e.g., Mainline Kernels) may cause Waydroid launch issue due to missing driver. See HERE for more.
The default options are usually OK. But, you may have to choose Android type before getting start:
Minimal Android – It’s vanilla ROM, without Google Services/Apps.
Android with Google Apps – come with Google Services/Gapps.
Next, click Download button will automatically download & install ROM and required packages. In my case, it downloaded & installed Android 13.
When done successfully, it will show you something like the screenshot shows you.
Tips: If you messed things up, try running the commands below one by one to delete local data, so it will look like newly installed:
After clicking “Done” button in last step, start Waydroid again will launch an Android screen on your desktop.
However, it by default starts in full-screen (or may-be called maximized) mode.
To change the Android screen size, open terminal (Ctrl+Alt+T) in the Ubuntu host, and run commands:
waydroid prop set persist.waydroid.width 506
waydroid prop set persist.waydroid.height 1000
The 2 commands will set the screen width and height to 506 x 1000. Change the numbers accordingly, and apply by running command to stop current Android session (then re-launch).
waydroid session stop
The Android window is borderless in my case. To move the window, you may either press & hold Super (Windows logo) key then dragging, or press Alt+F7 and then move mouse cursor without mouse clicking.
Step 4: Install & Remove Android Apps
If you selected ‘VANILLA’ while initializing Waydroid, then there’s no app store in the Android to install applications.
In the case, you may download any APK file from the web, or download & install the free open-source F-Droid in the host (Ubuntu in the case) then use it in Android screen to install apps.
UPDATE: Since Waydroid 1.6.0, you need to manually connect ADB via waydroid adb connect command first. And, authenticate in Android side.
To install APK file from host user’s ‘Downloads’ folder, just run command in terminal (Ctrl+Alt+T):
And, verify by listing all installed Android apps:
waydroid app list
Waydroid will create app shortcuts for all installed Android apps, through .desktop files under “.local/share/applications”. Meaning, you can search & launch Android apps directly from host machine (Ubuntu).
Launch ‘F-Droid’ Android app in Ubuntu
And, it supports launching multiple instance of Android apps at the same time out-of-the-box.
To remove an app, either do it in the Android screen, or run command in Ubuntu host:
waydroid app remove packageName
Replace packageName according to waydroid app list output, e.g., org.fdroid.fdroid.
Step 5: Share files between Ubuntu Host and Android
To share files between host and the Android system, simply run single command in Ubuntu host:
sudo mount --bind ~/Documents/vboxshare/ ~/.local/share/waydroid/data/media/0/Documents/share
Tips: It’s better to create sub-folders of Documents, Downloads, Music, etc in Android side for mount point mode.
In the command, you need to replace:
~/Documents/vboxshare/ – ‘vboxshare’ sub-folder in Ubuntu host.
~/.local/share/waydroid/data/media/0/Documents/share – ‘share’ sub-folder of Documents in Android.
You need to first create the share folder in Android side if it does not exist, or it will show mount point does not exist as the screenshot below shows you.
Uninstall Waydroid:
First, stop the session and container, which maybe useful for reloading settings, run commands:
Type user password (no asterisk feedback) when it asks and hit Enter to continue.
2. After adding the PPA, you can then launch Software Updater (Update Manager) and upgrade the system pre-installed transmission package to the new release.
For Ubuntu based system without the BitTorrent client pre-installed, you may run command below to install it:
This is a step by step beginner’s guide shows how to install LibreWolf web browser in all current Ubuntu releases, including Ubuntu 20.04, Ubuntu 22.04, Ubuntu 24.04, 24.10 and 25.04
LibreWolf is a free and open-source web browser fork from Firefox. The browser focuses on privacy and security, and has uBlocker ad blocker out-of-the-box.
The browser website has an official guide for installing in on Debian and Ubuntu based systems. This tutorial is just a re-write with screenshots and more explanations.
UPDATE: LibreWolf does NO longer provide official .deb package for Debian/Ubuntu users. Here’s how to install it through Flatpak package.
Install LibreWolf Flatpak package
The LibreWolf web browser now offers Linux package through Flatpak, which runs in sandbox environment. It works in most Linux and supports amd64 (Intel/AMD) and
arm64 (e.g., Raspberry Pi) platforms.
Linux Mint 21/22 and Fedora (with 3rd party repository) enabled may search & install the package either from Software Manager or GNOME Software.
While Debian and Ubuntu may run the commands below one by one to install:
First, open terminal (Ctrl+Alt+T) and run command to ensure Flatpak daemon is installed:
sudo apt install flatpak
For old Ubuntu 18.04, try adding this PPA for the daemon package.
Then, run command to install the web browser as Flatpak package:
NOTE: If the app icon is not visible after installation, either log out and back in to apply variable change, or run the command below to start it from terminal:
flatpak run io.gitlab.librewolf-community
Update LibreWolf
To check and install updates for the Flatpak package, just run command:
flatpak update io.gitlab.librewolf-community
For choice, you may install Warehouse, a graphical app to manage (include updateing) Flatpak packages.
Set LibreWolf as default web browser
For the default GNOME Desktop, open Settings (Gnome Control Center), then navigate to Default Applications in left pane. Finally, select “LibreWolf” from the drop-down box for Web.
For GNOME 46 (Ubuntu 24.04), Default Applications has been moved to “Apps” settings page.
Other desktops may have their own option to do the job. If you don’t know where to find the option, try editing the config file that works in most desktop environments. To do so:
First, open file manager and press Ctrl+H to show all hidden files and folders.
Navigate to .config sub-folder and click edit mimeapps.list file.
Finally, set librewolf.desktop for text/html, x-scheme-handler/http, x-scheme-handler/https and save file.
How to Remove LibreWolf Web Browser
To remove the web browser, also open terminal (Ctrl+Alt+T) and run command:
Shotwell photo viewer and organizer released new version 0.32.4 a few days ago.
The new release added basic .mpo file support, which is a stereoscopic image consisting of two overlapping 2D images in JPG format.
Besides that, the release also has improved slideshow support. It now supports for shuffled slideshows, allow setting wallpaper slideshows even if videos are selected, though videos are automatically excluded in slideshow in my case. And, fixes left/right navigation and not start issue in slideshow, when video is the first selected item.
Remove app shortcut for “Shotwell Profile Browser”. Add it as an action instead, though also available in ‘Preference’.
Simplified export conflict resolution dialog
New video meta-data handler.
Add dump of available image codecs and meta-data support
Fix showing the original photo with shift if photo was modified externally
Fix crop area jumping on scaled displays
Some crash fixes.
How to Install Shotwell 0.32.4 in Ubuntu:
Shotwell is available to install as Flatpak package, which is however not updated to the latest release at the moment of writing.
For those who prefer the classic .deb package format, I’ve upload the package into this unofficial PPA for Ubuntu 22.04, Ubuntu 23.04, Ubuntu 23.10 on amd64, arm64/armhf CPU architecture types.
1. First, search for and open terminal from your system application menu, or by pressing Ctrl+Alt+T on keyboard. When it opens, run command to add the PPA:
Type user password (no asterisk feedback) when it asks and hit Enter to continue.
2. Next, launch Software Updater (Update Manager), then install the updates for the software package.
Or, run command in terminal to install/upgrade the Shotwell package:
sudo apt install shotwell heif-gdk-pixbuf
NOTE: Linux Mint user may need to run sudo apt update first to refresh package cache.
Finally, either right-click on your photo images to select open with the photo manager, or search for and launch shotwell from ‘Activities’ overview and enjoy!
Uninstall Shotwell 0.32.4
For any issue, it’s recommended to purge the Ubuntu PPA. Which, will remove PPA and downgrade shotwell to the pre-installed version.
To do so, open terminal (Ctrl+Alt+T) and run command:
I’m using Virtualbox to try out different Linux Distributions in virtual machines. It always has 2 logo icons on Ubuntu dock: one for the manager, and another for VMs.
The VM and VM manager icons on the dock are totally same, causing me to make mis-clicks frequently. And, all the opened VMs are grouped into single icon on the dock.
If you don’t like this default behavior, then it’s easy to make Virtual Virtual Machines to have separate icon per instance.
As the screenshot below shows you, after following this tutorial, every VM will have its own system logo on Ubuntu Dock:
The VM icons for Linux are handled by virtualboxvm.desktop file under “/usr/share/applications” directory. Simply disable that file will make Virtualbox VM (7.0.12 in my test) fall back to separate icon with system/distro logo.
To do so, just create an empty file with same filename under “.local/share/applications”. It will be taken in use instead of the one in ‘/usr/share/applications’ for current user only.
Option 1: Single command to create empty virtualboxvm.desktop
Ubuntu user can press Ctrl+Alt+T on keyboard to open terminal, then run the single command below to create the empty file:
This command should work in most Linux, though running command mkdir -p ~/.local/share/applications may be required first to create the directory. Option 2: Use text editor to create empty virtualboxvm.desktop
For those who hate Linux commands, simply search for and launch a text editor window.
Then, it should by default open an empty file (if not create one). There open menu and select “Save as”.
In next dialog, name the empty file to virtualboxvm.desktop and save it into “Home > .local > share > applications”.
The change will be applied next time you launch a VirtualBox VirtualBox.
Method 2: Edit virtualboxvm.desktop
In case the first method does not work for you, you can configure the file to make it start VM as separate process.
1. First, open 2 “Files” windows. Then drag’n’drop virtualboxvm.desktop to local folder.
In “Files” (aka nautilus), navigate to Other Locations -> Computer -> usr -> share -> applications, then, find out the virtualboxvm.desktop file.
In another “Files” window, press Ctrl+H, then navigate to .local -> share -> applications. Finally, drag’n’drop the file to this folder.
2. Right-click on the virtualboxvm.desktop file in .local/share/applications folder and click “Open with Text Editor”.
When the file opens, add --separate flag to ‘Exec’ line. So it will be ‘Exec=VirtualBoxVM --separate %U‘.
For choice, you can change the icon to Icon=virtualbox-vbox, or replace with /path/to/whatever-icon that your want. However, all VMs will use the same icon on Ubuntu Dock.
How to Restore
To restore the change, simply delete the empty file either in your file manager or by running command in terminal:
Parole, the lightweight media player for XFCE Desktop, released version 4.18.1 few days ago.
The new release updates the app icons with 32px, 64px, 96px sizes support, so it should have a cleaner look in system menus like App Finder, Whisker Menu.
The extensions icons have been updated using newer Xfce palette, and semi-transparent borders giving it a sharper look in dark themes.
The system tray icon now is disabled outside X11. And, it now supports middle click actions to control video playback:
middle click to pause/resume playback.
middle wheel scrolling over tray icon to volume up/down.
Other changes in the release include:
Allow to built without X11 support and therefore whithout XfceSMClient.
Fix critical warning and memory leak
mpris2: Properly disconnect signal handlers
honor gtk-dialogs-use-header as Xfce 4.18 is CSD opt-in.
Small UI Improvements and many translation updates
How to Install Parole 4.18.1:
At the moment of writing, there’s no binary package of Parole 4.18.1 for Ubuntu.
But it’s not hard to compile the package from the source (tested in XUbuntu 22.04):
First, open terminal and run command to install the build dependency packages:
Extract the source tarball, then right-click on the new generated folder, and select “Open in Terminal”. Finally, run the 3 commands below one by one to compile it from source:
./configure
make -j4
sudo make install
NOTE: It by default installs the parole executable to /usr/local/bin without overriding the pre-installed one. Meaning you’ll have 2 versions of the media player installed in your system, while the app icon in menu will launch the newer 4.18.1 version.
(Uninstall) By opening the source folder in terminal, you may also uninstall the media player by running command:
