Linux power management and ACPI subsystems maintainer Rafael Wysocki last week sent out the assortment of ACPI/PM material for the new Linux 6.15 kernel cycle. The AMD P-State driver continues to be heavy with its code churn and there have been various other optimizations and code clean-ups. The CPUIdle Menu governor also received some performance tuning worth mentioning…

If you use a MySQL/MariaDB database, you know it can become slow or consume too many resources if not properly configured. To help with this, there’s a tool called MySQLTuner, which analyzes your database. It analyzes how MySQL/MariaDB is performing and provides tips to make it faster and more efficient.

KDE Plasma 6.3.4 delivers touch scroll fixes, scrollbar tweaks, better HDR support, and UI improvements to enhance desktop performance and usability.

The latest Scrcpy 3.2 is released with enhanced audio recording options, fixes for Android 15 and 16, and better compatibility with older operating systems.

This article is a tutorial on using UV to enhance or improve your Python work flow. If you work with Python you most likely have used one or all of the following tools: Why do you need another tool to manage your Python packaging or install your favorite Python tools? For me, using uv was […]

Not to be confused with the modern Compute Express Link (CXL) standard, but IBM’s Coherent Accelerator Interface “CXL” / Coherent Accelerator Processor Interface “CAPI” support was stripped away today from the mainline Linux kernel…

A subtitle editor is a type of computer software that lets users create and edit subtitles. We pick the finest open source options.

Merged today for the Mesa 25.1-devel graphics driver code and also marked for back-porting to the Mesa 25.0 OpenGL/Vulkan drivers is another new Intel Battlemage device ID…

Saying that calibre is
ebook-management software undersells the application by a fair
margin. Calibre is an open-source Swiss Army knife for ebooks that can
be used for everything from creating ebooks, converting ebooks from
obscure formats to modern formats like EPUB, to serving up an ebook
library over the web. The most recent major release, calibre 8.0,
brings a better text-to-speech engine, a tool for creating audio
overlays when authoring ebooks, support for profiles in the ebook
viewer, and more.

Thunderbirds are Pro: Open-source email client to get message hosting, appointment scheduling, moreThunderbird, Firefox maker Mozilla’s open-source email client, is aiming to reinvent itself as a more comprehensive communications platform.…

José Marchesi and David Faust kicked off the BPF track at the 2025 Linux Storage,
Filesystem, Memory-Management, and BPF Summit with an extra-long session on what
they have been doing to support compiling to BPF in GCC. Overall, the project is slowly working
toward full support for BPF, with most of the self-tests now passing using
Faust’s in-progress patches. However, the progress toward that goal has turned up
a number of problems with how Clang supports BPF that needed to be discussed at
length to find a path forward for both projects.

Ryan Sipes has announced
efforts to expand Thunderbird’s offerings with web services to
“enhance the experience of using Thunderbird“.

The Why for offering these services is simple. Thunderbird loses users
each day to rich ecosystems that are both clients and services, such
as Gmail and Office365. These ecosystems have both hard vendor
lock-ins (through interoperability issues with 3rd-pary clients) and
soft lock-ins (through convenience and integration between their
clients and services). It is our goal to eventually have a similar
offering so that a 100% open source, freedom-respecting alternative
ecosystem is available for those who want it.

The planned services include hosted email, appointment scheduling,
a revival of Firefox Send,
and (of course) an AI assistant based on a partnership with Flower AI. The AI features will
“always be optional for use by people who want them“. Sipes is
managing director of product for Thunderbird’s parent organization, MZLA
Technologies Corporation. LWN covered his
GUADEC 2024 keynote last July.

Incus 6.11 container & virtual machine manager is out with initial Linstor support, improved VM and OCI container features, enhanced network options, and more.

Last week I posted some initial GNOME 48 and KDE Plasma 6.3 desktop gaming benchmarks on Ubuntu 25.04 beta for looking at the performance of those two leading desktop options for this upcoming Ubuntu Linux release. Both GNOME and KDE under Wayland were outperforming KDE on X11 (and GNOME on X11 wasn’t even working due to bugs). Some Phoronix readers questioned though whether the Wayland advantage on GNOME/KDE was due to those desktops losing focus on X11 support or if they are just too bloated. So for adding some additional context, here are some graphics/gaming benchmarks on the same system hardware/software when adding in the Xfce 4.20 and LXQt 2.1 X11 desktops.

Outgoing Fedora Project Leader (FPL) Matthew Miller has announced
his successor, Jef Spaleta.

Some of you may remember Jef’s passionate voice in the early Fedora
community. He got involved all the way back in the days of fedora.us,
before Red Hat got involved. Jef served on the Fedora Board from July
2007 through the end of 2008. This was the critical time after Fedora
Extras and Fedora Core merged into one Fedora Linux where, with the
launch of the “Features” process, Fedora became a truly community-led
project.

Spaleta will be joining Red Hat full time in May and Miller will be
formally handing off FPL duties at the Flock conference in
June.

Version
2.0 of PorteuX, a distribution based on Slackware Linux, has been
released. This release adds the ability to test experimental Wayland
sessions for the Cinnamon, LXQt, and Xfce desktops. PorteuX 2.0
updates the Linux kernel to 6.14 and includes many package updates and
bug fixes. Users have the choice of PorteuX stable or its rolling release
called current. See the install.txt
for instructions on installing PorteuX to disk.

This morning’s Intel TDX update reminded me that I still hadn’t gotten around to digging into the Kernel-based Virtual Machine (KVM) changes merged last week for the ongoing Linux 6.15 kernel merge window. Here is a look at the KVM changes this cycle that continue to be particularly heavy on Intel and AMD virtualization improvements…

As part of the various areas of the kernel overseen by Greg Kroah-Hartman, on Sunday he sent out the driver core updates for the Linux 6.15 kernel. The driver core changes this cycle aren’t too notable except for revising the Rust bindings now that more developers are attempting to use them…
