MX Linux 25.3 “Infinity” is now available, bringing refreshed installation images, Debian 13.7 updates, newer kernels, updated graphics components, and several improvements to the distribution’s own collection of tools.
For existing MX Linux users, there is no need to reinstall. The project says the updates are already flowing through its normal update channels. These new MX Linux 25.3 ISOs are mainly for fresh installations.
Most editions ship with the Linux 6.12.107 kernel, but the Xfce AHS release takes a different approach. That image includes the Liquorix 7.2.6 kernel for users who want newer hardware support.
The AHS releases also include Mesa 26.1.4 and firmware backported from Debian Sid. That should make them the more obvious choice for people installing MX Linux 25.3 on newer PCs, especially systems with recent graphics hardware.
MX Linux 25.3 also includes all Debian updates through Debian 13.7 along with updates from the MX repositories. The MX team has been rolling out many of its changes over time, but this release still brings several additions worth calling out.
MX Welcome, MX Tools, and the custom toolbox used by Fluxbox have received interface facelifts. MX Linux has also added a new utility called Verify ISO Sig, which can verify digital signatures for MX Linux images as well as ISOs from several other Linux distribution families.
That is actually a useful addition. Downloading Linux ISOs is easy, but verifying that an image is legitimate is something many users still skip. Putting a dedicated verification tool directly into MX Linux lowers the barrier a bit.
There is also a new MX Theme Colors utility for creating custom highlight themes based on existing MX GTK themes. It is a smaller addition, but it gives users another easy way to change the look of the desktop without digging into configuration files.
MX Package Installer has picked up some changes too. Siduction 7.x kernels are now available through the Popular Apps section under kernels, while several third-party VPN installers have been updated.
New MX Linux 25.3 installations will also configure lazytime in fstab by default. The change can reduce unnecessary filesystem metadata writes by delaying certain timestamp updates.
Documentation has been refreshed as well, including updates to the manual, FAQ entries, translations, bug fixes, maintenance changes, and feature releases introduced since the previous official MX Linux release.
The project is also offering an updated Raspberry Pi respin, although there is one issue worth knowing about before installing it. Automatic filesystem expansion on first boot has been removed because the previous methods became unreliable. Raspberry Pi users will instead need to run raspi-config after the first boot and expand the filesystem manually.
MX Linux has always appealed to people who like Debian but want more convenience layered on top. MX Linux 25.3 keeps that formula intact while giving users a choice between a conservative standard kernel and a much newer option for newer hardware.
If you are already running MX Linux, there is little reason to touch the new ISO images. If you are installing from scratch, however, MX Linux 25.3 gives you refreshed media, current Debian updates, and more flexibility when choosing how aggressively you want to chase newer hardware support.
MX Linux 25.3 is available in Xfce, Xfce AHS, KDE, and Fluxbox editions. Grab an ISO here.
