4MLinux 51.0: Linux 6.12 LTS and Mesa 25.3.1

4MLinux 51.0: Lightweight Distro with Linux 6.12 LTS and Enhanced Graphics

Developer Zbigniew Konojacki has released 4MLinux 51.0 — a minimalist GNU/Linux distro with JWM. The build uses the Linux 6.12 LTS kernel, Mesa 25.3.1, updated drivers for modern GPUs, and automated hardware setup. Live images are available: graphical (x86_64, 2.2 GB) and console (x86_64, 16.2 MB).

Key Package Updates

4MLinux 51.0 includes the latest versions of system and user components. Main changes:

• Mesa 25.3.1 (VAAPI, Vulkan for new GPUs), Mesa 21.3.9 (VAAPI, VDPAU for legacy adapters), Intel VAAPI (i965/iHD);
• Firmware for AMD, Intel, NVIDIA;
• BusyBox 1.37.0, PHP 8.4.14, Perl 5.42.0, Python 3.13.8, Ruby 3.4.7;
• LibreOffice 26.2, GNOME Office (AbiWord 3.0.7, GIMP 3.0.8, Gnumeric 1.12.60);
• Browsers: Firefox 149.0, Chrome 146.0; email: Thunderbird 140.9;
• Multimedia: Audacious 4.5.1, VLC 3.0.23, SMPlayer 25.6.0.

The system supports emulation of AY/YM sound chips (libayemu) for ZX Spectrum and Atari. Add-ons: Midori (browser), cmus (ncurses player).

Graphics Stack and Hardware Compatibility

The Linux 6.12 LTS kernel provides stability for long-term support. The Mesa 25.3.1 graphics stack is optimized for hardware acceleration: VAAPI/Vulkan on new GPUs, VDPAU on older ones. Intel VAAPI covers i965 and iHD drivers. Automatic hardware detection applies optimal settings, minimizing manual configuration.

Minimum RAM requirements (64-bit):

• 250 MB for HDD installation;
• 2000 MB for live CD/USB.

JWM as the window manager ensures low resource usage, suitable for old hardware or embedded systems.

Use Cases

4MLinux is ideal for:

• Live environments with multimedia (VLC, SMPlayer, Audacious);
• System recovery after crashes;
• Mini-servers (HTTP/FTP via BusyBox 1.37.0, PHP/Python/Perl/Ruby);
• Gaming on Mesa 25.3.1;
• Retro platform emulation (ZX Spectrum, Atari).

A 4MLinux Server demo is available on the project website with BusyBox or thttpd for testing server capabilities.

Key Highlights

• Linux 6.12 LTS + Mesa 25.3.1 with full driver coverage (VAAPI/Vulkan/VDPAU) for x86_64;
• Automatic hardware optimization without manual tweaks;
• Updated development stack: Python 3.13.8, PHP 8.4.14, Ruby 3.4.7;
• AY/YM emulation for retro computing + new add-ons (Midori, cmus);
• Low requirements: from 250 MB RAM on HDD.
