MX Linux 25.3 is now available with refreshed installation images built around the latest Debian 13.7 updates and the project’s own package changes. The “Infinity” point release is aimed mainly at new installations, but it also gives existing users a clear view of what has reached the MX repositories since the previous image update.
MX remains a popular choice for people who want a stable Debian base without giving up practical desktop tools. This release continues that formula. It updates the core image, improves the experience for newer hardware, and adds a few utilities that make everyday maintenance less awkward.
What changes in MX Linux 25.3
MX Linux 25.3 includes the Debian 13.7 package set and the MX updates published since the prior official ISO. Most editions ship with the Linux 6.12 kernel. That combination keeps the familiar MX desktop experience while giving a new installation a more current foundation from the first boot.
Fresh install media, not a forced reinstall
Existing users do not need to download an ISO and start over. MX distributes the same package updates through its usual channels. The new images matter most when you are setting up a new computer, rebuilding a machine, or creating installation media that should need fewer updates immediately after setup.
Newer hardware gets a distinct AHS path
The Xfce AHS edition targets newer hardware. In MX Linux 25.3, it uses the Liquorix Linux 7.2 kernel rather than the standard 6.12 series. The AHS images also move to Mesa 26.1 and include newer firmware packages backported from Debian Sid.
Choose the image to match the machine
That does not make AHS the automatic choice for every user. Older or well-supported hardware may be better served by the standard images. The AHS route makes most sense when a newer graphics stack, newer firmware, or current hardware support is the priority.
Small tools with a useful purpose
The project also refreshed MX Welcome, MX Tools, and the Fluxbox edition’s toolbox interface. More notably, MX Linux 25.3 adds Verify ISO Sig, a utility for checking an ISO image’s digital signature. It is not limited to MX downloads, which makes it useful for anyone who keeps installation media for several Linux distributions.
Another new tool, MX-Theme-Colors, can create GTK highlight-colour variations from existing MX themes. The MX Package Installer has received updates too, including newer kernel choices and revised third-party VPN installation options.
A change worth noting for fresh installs
For new installations, the MX/Gazelle installer now enables the lazytime mount option in /etc/fstab by default. This setting can reduce some metadata-write overhead by delaying timestamp updates. It is a subtle change, but it shows the project is still looking for sensible defaults rather than chasing cosmetic changes alone.
If kernel freedom is the deciding factor in your next system, our introduction to the GNU Linux-libre kernel explains why its approach differs from the standard kernels included by most distributions.
Which MX Linux 25.3 image should you choose?
- Choose the standard Xfce, KDE Plasma, or Fluxbox image for familiar MX hardware support.
- Choose Xfce AHS if your computer needs a newer graphics stack or more recent firmware.
- Use the Raspberry Pi respin only if you are comfortable handling its current first-boot filesystem-resize step.
- Update an existing MX installation through the normal package tools instead of reinstalling.
A smoother starting point for new MX systems
MX Linux 25.3 does not reinvent the distribution. It gives new installs a cleaner baseline, lets newer hardware use a more capable AHS image, and improves the tools that help people manage a system after installation. For many MX users, that is exactly what a point release should do: reduce setup work while keeping the desktop dependable.
