Last updated: January 1, 2023 — 1 Comment

For Chinese users or those who have friends or business in China, native QQ app is finally working well in Linux by releasing the 3.0 version!

QQ is one of the top popular instant messaging apps in China. It has an official Linux client since 2019, which was however old, crash often, and not suitable for daily use.

By releasing 3.0, QQ for Linux finally got a modern UI powered by its QQNT framework. Similar to the Windows app, it has the user avatar and a few navigation buttons in far left pane, friends and group chats in center, and messages in right.

This Extension Adds Audio Visualizer on Desktop in Ubuntu 22.04

Last updated: May 8, 2024 — Leave a comment

Want to display audio/music visualizer on the desktop? This extension can do the job for Ubuntu 22.10, Fedora 37, Arch/Manjaro Linux with GNOME.

It’s “Sound Visualizer” extension for Gnome Shell based on Gstreamer specially for Wayland. And, it’s working good in my case in Ubuntu 22.04, though it’s said for Gnome v43.

Besides for music playback, it works when any sound play from your computer. And, it has a right-click menu to switch between input/output audio sources. Meaning, it supports sounds input from microphone.

How to Install this “Sound Visualizer” desktop widget

1. (For Ubuntu 22.04 only) As mentioned, the extension supports GNOME v43 at the moment of writing. If you want to try it out in 22.04, first disable extension version validation.

To do so, press Ctrl+Alt+T on keyboard. When it opens, run command (no longer required):

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

2. Next, open Ubuntu Software. Search for and install ‘Extension Manager‘ tool for installing and managing Gnome Shell extensions. Or, run command in terminal in case the Software App does not work.

sudo apt install gnome-shell-extension-manager

Install Extension Manager in Ubuntu 22.04+

3. Finally, launch ‘Extension Manager‘, and navigate to ‘Browse‘ tab. Search for and install the ‘Sound Visualizer‘ extension. (For Ubuntu 22.04, just click on Unsupported button)

For Fedora 37, Arch and Manjaro Linux with GNOME, visit this page in web browser and use the ON/OFF switch to install it.

4. After installation, try playing some sounds and see your desktop for the result. To move the widget, you have to temporarily disable “Desktop Icons NG (DING)” under ‘Installed’ tab in Extension Manager.

You can also adjust the visualizer size by opening the extension preferences either via widget’s context menu or by clicking the gear button for that extension in Extension Manager.

HandBrake 1.6.0 is a big release with new AV1 video encoding support. They are SVT-AV1 (software) and Intel QSV AV1 (hardware) video encoders.

This release as well introduced high bit depth and color depth support to various encoders and filters, including VP9 10-bit, NVENC HEVC 10-bit, and VCN HEVC 10-bit encoders.

Other change include:

  • 4K AV1 General, QSV (Hardware), and MKV (Matroska) presets
  • 4K HEVC General presets
  • H.264 levels 6, 6.1, and 6.2 for the x264 encoder
  • H.264/H.265 4:2:2 and 4:4:4 profiles for the x264 and x265 encoders
  • H.265 4:2:2 profile for VideoToolbox encoder on Apple Silicon
  • Support for Intel Deep Link Hyper Encode
  • Fixed longstanding issue where slowest NVENC encoder preset caused encoding failures
  • Bwdif deinterlace filter
  • Remove VP8 presets, the VP8 video encoder is now deprecated
  • Remove support for Intel CPUs older than 6th generation (Skylake) when using Intel Quick Sync Video
  • Require .NET 6 for Windows.
  • See more details in the project releases page.

How to Install HandBrake 1.6.0 in Ubuntu:

NOTE: Please backup custom presets and preferences first if you’re trying to upgrade the software from an existing package.

HandBrake offers official Linux package through Flatpak, an universal package format runs in most Linux. For Ubuntu, simply follow the steps below one by one to install it.

1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to make sure the daemon package installed:

sudo apt install flatpak

For the old Ubuntu 18.04, add this PPA first.

2. Then, either run command to install the video transcoder as Flatpak from Flathub repository by running command:

flatpak install https://dl.flathub.org/repo/appstream/fr.handbrake.ghb.flatpakref

The package in this repository is not updated to v1.6.0 at the moment of writing, check the link page to before running the command.

Or, download the flatpak package file from the official website:

Download HandBrake

Finally, open terminal (Ctrl+Alt+T), navigate to ‘Downloads folder’ via command:

cd ~/Downloads

And, install the local Flatpak file (change file-name in command accordingly) via:

flatpak install ./HandBrake-1.6.0-x86_64.flatpak

NOTE: If it refuses to install due to old version already installed. Remove it first via description below.

Duplicated shortcut icons:

The Flatpak package won’t override the native Deb package installed from Ubuntu Software. If you have both versions installed, you’ll have duplicated app icons.

As a workaround, either remove the old Deb package via Ubuntu Software, or launch HandBrake as Flatpak using the command in terminal:

flatpak run fr.handbrake.ghb

Uninstall HandBrake

To remove the video transcoder installed as Flatpak, open terminal (Ctrl+Alt+T) and run command:

flatpak uninstall --delete-data fr.handbrake.ghb

Also remove the QuickSync plugin (if installed) via command:

flatpak uninstall --delete-data fr.handbrake.ghb.Plugin.IntelMediaSDK

Finally, clear unused run-time libraries via flatpak uninstall --unused.

This App Enhance your Photo Images to 4K Resolution or Higher

Last updated: December 27, 2022 — Leave a comment

Got photo images but not clear enough? Or you want to convert them into 4K resolution without losing quality? This app can help!

It’s upscayl, a free and open-source app for Linux, Windows, and macOS. It uses AI modules to upscale single or batch of photo images into 7680×5120 (or double resolution 15360×10240). Supported AI modules so far include:

  • Real-ESRGAN
  • REMACRI
  • ULTRAMIX BALANCED
  • ULTRASHARP

The app has a quite easy to use user interface, which has a few buttons in left pane and image preview in right. Just follow the steps in the UI to select your Photo Image/Images, choose AI module, where to save output image, and finally click upscale.

There are as well advanced options to choose output image format: PNG, JPG or WEBP, change the app theme, and specify GPU ID for machine with multiple graphic cards. As you can see in screenshot above, output image and original one will be displayed side by side when process done, allowing to see the difference intuitively.

How to Install Upscayl in Ubuntu & other Linux

NOTE: The app needs Vulkan compatible GPU to upscale images. And, the upscale process can take long time depends on your machine.

The app offers official packages in it Github releases page available to download at the link blow:

Download Upscayl

For Linux, either download the non-install AppImage package. Right-click and go to file ‘Properties’, and enable ‘Allow executing file as program’ in Permissions tab. Finally click run AppImage at anytime to launch it. NOTE: Ubuntu 22.04+ need to enable AppImage support first by running sudo apt install libfuse2 in terminal.

For Debian/Ubuntu based systems, grab and click install the .deb package for choice. And, Fedora based systems can download and install the .rpm package instead.

Uninstall Upscayl

In case you installed the app using .deb or .rpm package, and you can’t find it in the Software app. Open a terminal window, and run command to remove it in Debian/Ubuntu:

sudo apt remove upscayl

For Fedora, just replace apt with dnf, so the command will be:

sudo dnf remove upscayl
