NVIDIA announced the first stable release of the 555 series driver for Linux few days ago.

It’s NVIDIA 555.58, the latest new feature branch version. The release now uses GSP firmware by default on all GPUs that support it (e.g., Tesla T4, T10, A100 series).

GSP, stands for GPU System Processor, acts like a CPU embedded into the GPU, it can be used to offload GPU initialization and management tasks. To disable this feature, user can just add NVreg_EnableGpuFirmware=0 kernel parameter to /etc/default/grub config file if boot with Grub2.

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!

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.
