Today is the day! — Nitrux 3.7.1 “sp” is available to download

We are pleased to announce the launch of Nitrux 3.7.1. This new version combines the latest software updates, bug fixes, performance improvements, and ready-to-use hardware support.

Nitrux 3.7.1 is available immediately.

🔰 Information: The codename for this release is “sp,” which highlights the improvements to security and performance in this release.

⚠️ Important: Despite the efforts and improvements in this and previous releases, we’re not claiming to be security or forensic experts or that the distribution is “impenetrable” or “unhackable,” so there isn’t any misunderstanding. Suggestions to continue improving on this area are welcome at our organization at GitHub (open a new discussion).

🔰 Information: The ISO file is signed with a GPG key, and we only provide SHA512 checksum files; please check the Notes to know more.

We thank our friends at Packagecloud for providing Nitrux Latinoamericana with the vital infrastructure needed to build our distribution.

Lightning-fast, secure, automated package management.

  • Valve’s gamescope to version 3.15.3.
  • We’ve updated our base-files package to correct the Debian base codename to trixie/testing.
  • Our Sysctl settings have been updated with the additional changes for better security and increased performance.
      • Increase Linux autotuning TCP buffer limits. These TCP buffer settings enhance high-speed network performance by dynamically adjusting buffer sizes to improve throughput, reduce packet loss, prevent congestion, and ensure smooth data transfers, all while efficiently managing system memory.
      • Increase the maximum number of packets queued for processing before they are dropped. It improves the handling of burst traffic, reduces packet drops, and enhances performance and stability on high-speed networks during heavy loads.
      • Reuse Time-Wait TCP connections to reduce the number of open TCP connections. Efficiently manage network connections, reducing open TCP connections, freeing up system resources, and improving performance.
      • Enable Reverse Path Filtering. It prevents IP spoofing attacks, enhances security, and reduces vulnerability to DDoS attacks.
      • Disable Source Routing. Prevents IP spoofing and strengthens security by disabling source routing, blocking potential bypassing of security controls.
      • Restricts access to kernel pointer addresses. Improves security by restricting access to kernel pointer addresses to privileged processes, preventing information leaks.
      • Disable the SysRq key. It enhances security by disabling the SysRq key and preventing unauthorized system commands.
      • Disable timer migration across CPUs. Improve the CPU scheduling consistency for real-time or latency-sensitive applications by disabling timer migration across CPUs.
      • Control the boost applied to the watermark (the minimum number of free pages the kernel tries to maintain). Maintain higher free memory to ensure the system doesn’t stall due to memory shortages.
      • Change dirty page settings to reduce I/O disk access. Allow for efficient memory usage without frequent disk access.
  • We’ve updated our desktop settings to include the following.
    • Enable soft wrap and word wrap by default in micro.
  • We’ve updated our SDDM configuration with the following changes.
    • Organize our configuration files in /etc/sddm.conf.d.
    • Add configuration files for SDDM to use rootless Wayland or X11.
      • ⚠️ Important: SDDM using Wayland is experimental. From our tests, we encountered problems when using SDDM on Wayland and the NVIDIA proprietary driver; specifically, games using DXVK or VKD3D were crashing or only showed a black screen; this problem was not present when using the MESA drivers.
  • We’ve updated our configuration for Calamares, which includes the following changes.
    • Ensure the kernel parameters used for the installation match those in the Live ISO for the following features.
      • Enable support for AMD GCN 2.0 (CIK) GPUs in the AMDGPU driver.
      • Change the update mode for the virtual memory in the AMDGPU driver to improve performance in specific workloads.
      • Disable the High Precision Event Timer (HPET) for systems where it may cause issues.
      • Enable expedited RCU grace periods, improving system responsiveness in specific scenarios.
    • Add new kernel parameters for the following features to improve performance and security.
      • Offload all RCU (Read-Copy-Update) callbacks to kernel threads, reducing interrupt contention on CPUs.
      • Enable “lazy” RCU mode, delaying some operations to optimize performance.
      • Enable additional security checks for user copy operations.
      • Disable the 32-bit VDSO (Virtual Dynamic Shared Object) on 64-bit systems.
      • Enable Kernel Control Flow Integrity (KCFI). This security feature helps prevent specific attacks, like control flow hijacking, by ensuring that indirect function calls are only made to valid, expected targets.
    • Create the group gamemode and add the user to it to avoid permission issues when GameMode applies the settings from its configuration file.
  • Extensible Virtual Display Interface (EVDI) driver to version 1.14.7.
  • DisplayLink driver to version 6.1.0.
  • AppArmor to version 4.1.0-beta1.
  • Updated xone driver to a fork that compiles against Linux 6.11+.
  • We’ve updated our slight modifications to casper to remove configuration for display managers other than SDDM during the Live session.
  • We’ve updated the included offline Documentation.

We’ve added the following components to the distribution.

  • Add an OpenRC service script to identify the Broadcom wireless chip used for wlan0 and decide which driver to load (b43, b43legacy, wl, or brcmsmac) during boot, as not all Broadcom chips are supported by the open source drivers or the support is partial or untested.
  • Add module configuration to disable 40mhz bandwidth on the 2.4ghz band for the Broadcom BCM4360 wireless chip when using the Broadcom proprietary driver to avoid connection issues.
  • Add firmware for the Broadcom BCM4301, BCM4306/2, and BCM4306 wireless chips.
  • Add firmware for Facetime HD (Broadcom 1570) PCIe webcam found in recent MacBooks.
  • Add 32 and 48px-size icons for CoreCtrl.
  • Add default configuration file for GameMode.
  • Add a configuration file for Bluetooth audio devices using the SBC audio codec (not to be confused with SBC-XQ) to achieve a balance between audio quality and bandwidth efficiency, ensuring a reliable and high-quality Bluetooth audio experience.
  • KZones. A KDE KWin Script that snaps windows into zones.
