OpenShot 3.2.0 Released with Great Performance Improvement

Last updated: June 29, 2024 — Leave a comment

OpenShot released version 3.2.0 a few days ago with great performance improvements.

OpenShot is a free open-source Qt-based video editor works on Linux, Windows, and macOS. Due to its beginner friendly menu options, built-in title templates, and animated titles (Blender powered), I prefer it over Kdenlive and Shotcut.

However, the video editor was sluggish, froze frequently, and slow for video preview playback every time after made changes. It made me crazy quite often, so I turned to learn using Kdenlive for basic editing.

In OpenShot 3.2.0, the video editor has significant performance enhancements. It’s now running smoothly out-of-the-box in my Ubuntu 24.04 laptop!

Last updated: June 25, 2024 — Leave a comment

This tutorial shows how to hide (or auto-hide) the top bar in Ubuntu 24.04, Ubuntu 22.04, and/or Ubuntu 20.04 with default GNOME Desktop.

Like the left (or bottom, if you moved it to) dock panel, the top bar can be hidden in Ubuntu and other Linux with GNOME Desktop to save screen space. And, this can be done by using one of the following extensions:

Just Perfection – GNOME UI & behavior config tool with many toggle options, including hide top-bar.
Hide Top-bar – support intellihide, that hides only when app window hit screen top or maximized.
Hide Panel Lite – very light version that only hide top-bar, except in overview. However, so far supports ends at GNOME 42.
Dock Unroll – light version that support GNOME 46.

Last updated: June 21, 2024 — 1 Comment

KeePassXC, the popular free open-source KeePass and KeePassX based password manager, released version 2.7.9 few days ago.

The new KeePassXC 2.7.9 installed as Snap finally uses new desktop portal for native messaging integration. Meaning without using an external script, it now has out-of-the-box browser integration support. However, KeePassXC seems no longer provides official support for Snap package.

So far, Firefox (native + Snap), Chromium Snap, Google Chrome native, Brave native are tested and work with KeePassXC installed as Snap. Though, user may need to grant permission by running the command below in terminal:

sudo snap connect keepassxc:browser-native-messaging

Since version 2.7.7, the password manager added basic Passkeys/WebAuthn support, and added a context menu option to import passkeys. In the new release, it improved the feature by adding a new “Remove Passkey from Entry” context menu option.

Enable JPEG-XL (.jxl) Image Support in Ubuntu 24.04 & 22.04

Last updated: June 20, 2024 — 2 Comments

This tutorial shows how to enable .jxl file support for system image viewer, GIMP, and some other apps in Ubuntu 24.04, Ubuntu 22.04, Ubuntu 20.04, and even Ubuntu 18.04.

JPEG-XL is a new image format by JPEG committee. It supports both lossy and lossless compression, and includes features such as animation, alpha channels, layers, thumbnails, and has better compression efficiency (60% improvement) comparing to JPEG.

For encoding and decoding JPEG-XL images, there’s a free open-source libjxl library available. Ubuntu has included the library in system repository since 24.04, however lacks GdkPixbuf loader plugin until Ubuntu 24.10 (still in development so far).

Meaning system default image viewer, and many other apps do not work with .jxl file in current 3 Ubuntu LTS releases out-of-the-box.

For the most recent versions, 3rd PPAs so far are the only choices besides building from the source tarball.
