Filesystem, Security, Privacy, and Anonymization Features in Nitrux
- Nitrux provides multiple ways to encrypt information, including block-device using dm-crypt; see File Encryption in Nitrux, filesystem-level using f2fscrypt, and userland encryption tools like fscrypt and Plasma Vaults.
- Nitrux enables multiple security features and policies by default in addition to any encryption capabilities; see Default Security Policies in Nitrux.
- And, since Nitrux 2.6.0, the root directory is default set to be immutable, meaning no changes occur to its contents; see XFS Features and Root Immutability in Nitrux.
- Additionally, since Nitrux 2.8.1, the distribution includes other security mechanisms, such as the following.
- Advanced Intrusion Detection Environment, or AIDE, is an intrusion detection system that detects changes to files on the local system. It creates a database from the regular expression rules that it finds from the config file.”; see Using and Configuring AIDE.
- Utilities to protect user’s privacy and anonymity while browsing the Internet; see Online Anonymization using Tor and DNSCrypt-Proxy 2.
- System-wide ad-blocking using dbab; see Ad-blocking in Nitrux using dbab.
- 🔰 Information: For more extensive information about configuring dbab, see the documentation for dbab.
Upgrading Nitrux from a Previous Version
- To upgrade from previous versions of Nitrux, check our tutorial on How to Upgrade Nitrux.
Using NX Desktop
- To get acquainted with using NX Desktop, see the tutorial about using NX Desktop.
- Nitrux is a distribution that doesn’t revolve around a package manager like other distributions; in Nitrux, the preferred method of obtaining new software is using AppImages. However, we understand that not all software is available as an AppImage. So, by default, we have included various options for users, such as Flatpak and Distrobox, to complement AppImages.
- To learn how to manage software in Nitrux, see the tutorial about Software Management.
- Users can also create their AppImages; to do that, see the following tutorials.
Creating and Managing Backups
- Nitrux allows users to back up their data using Kup since version 1.1.9 (July 27th, 2019). You can find Kup in System Settings>Backups.
- To use it, see How to create backups using Kup.
Creating OpenRC and User Services
- Nitrux does not use systemd as its init system; instead, it uses OpenRC.
- See How to create service files in Nitrux pt. 1: OpenRC to create and use system services.
- See How to create service files in Nitrux pt. 2: User to create and use user services.
Creating Network Shares
- Nitrux includes support for Samba and NFS shares.
- To create and use Samba shares, see How to create and access Samba shares in Nitrux.
Support for Other Desktop Environments
- Nitrux uses the Plasma Desktop with our customization layer NX Desktop by default. Also, our desktop shell, Maui Shell, is in development. In this regard, our focus is on Plasma and MauiKit. However, users can install other desktop environments using Distrobox. With that said, see our tutorial, Installing other DEs in Nitrux.
- ⚠️ Important: Using Distrobox to install other desktop environments is a feature considered “an experiment” by the Distrobox developer, so keep that in mind.
- Regarding Maui Shell, as of September 1st, 2023, Maui Shell development focuses on Qt6. Therefore, for now, we’re not providing new ISO files. To test Maui Shell, please compile it using a container.
- ⚠️ Important: Please report issues with Maui Shell at its bug tracker.
- Starting with Nitrux 2.8.1, the distribution uses a Wayland session (Plasma Wayland) by default.
- Since Nitrux 2.6.0, the distribution includes PipeWire by default.
- As of Nitrux version 2.4.0, we include the most recent version of MESA available, built from MESA’s Git ‘master’ branch, not the “stable” release as most distributions do.
- ⚠️ Important: Since we include bleeding edge software YMMV. Please report issues with MESA to the MESA developers.
- If using a graphics processor that uses MESA drivers and the GUI does not work, check whether your GPU is loading its firmware. To check, run the following command after login to a TTY.
lspci -v | grep -A 10 -i "VGA compatible controller" lshw -C display
Disclaimer: We do not develop or package MESA. To file bugs against MESA, please use their bug tracker here.
Plasma X11 Session Information
- Starting with Nitrux 2.8.1, the Plasma X11 session is not the default anymore. However, we understand that for many users, especially those with Nvidia graphic processors, using Wayland may not provide the best experience. For these users, run the command below to restore the Plasma X11 session as a selectable session in SDDM.
- After running the command below, log out, select Plasma X11, and log in.
sudo mv /usr/share/xsessions/orig.plasma.desktop.bak /usr/share/xsessions/plasma.desktop
Latte Dock Information
- As of July 2022, Latte Dock is now unmaintained by its developer, meaning there’s no guarantee it will continue to work. Since Nitrux 2.9.0, Latte Dock is no longer included in the distribution.
Nvidia Proprietary Driver Information
Please note that starting from version 2.5.0 Nitrux includes the latest available Nvidia proprietary driver.
- Nitrux includes the latest version of the Nvidia proprietary driver when we build and publish our ISO files.
Disclaimer: We do not develop the Nvidia proprietary driver. For issues with the Nvidia driver, including bugs and adding support for graphics cards, please visit Nvidia Support.
- For some laptops with supported discrete graphics by the Nvidia proprietary driver, adding our X11 configuration for PRIME (where supported) may be necessary to work correctly.
- Download the script below to add our X11 configuration if your laptop requires it.
- ⚠️ Important: The script file below creates files in the root directory; see XFS Features and Root Immutability in Nitrux.
- 🔰 Information: The default TTY for the graphical session can change if your computer utilizes the Nvidia proprietary driver.
- Download the script below to add our X11 configuration if your laptop requires it.
axel -a -o $HOME/Downloads https://raw.githubusercontent.com/Nitrux/storage/master/Other/nvidia-x11-laptop-conf chmod +x $HOME/Downloads/nvidia-x11-laptop-conf sudo $HOME/Downloads/nvidia-x11-laptop-conf
General Gaming Information
- Nitrux uses the Liquorix kernel, described as “an enthusiast Linux kernel designed for uncompromised responsiveness in interactive systems, enabling low latency in A/V production, and reduced frame time deviations in games.”
- To install Proton-GE in Nitrux, see Gaming in Nitrux pt. 1: Get Started.
- Nitrux includes a desktop launcher to install Steam, Bottles, and Heroic Games Launcher from the applications menu; we do not include these applications by default.
- Alternatively, users can install Lutris (from Flathub) to run Windows software.
Disclaimer: We do not develop Steam or the Steam Flatpak. To report issues about the Steam Flatpak, create an issue at their bug tracker. Also, we do not develop Bottles, Heroic Games Launcher, or Lutris. Please create an issue at their respective bug trackers to report problems with these applications.
- Nitrux includes a desktop launcher to install the itch.io Store application, which will download and run the official Linux installer; we do not include it by default.
- 🔰 Information: For more information about running the itch.io Store application in Nitrux, see itch.io Store.
Disclaimer: We do not host, maintain, or create the content at the itch.io Store, nor develop the itch.io client Store application. Please file bug reports at their bug report website here.
Using Kernel Boot to swap Kernels
- The Kernel Boot (kboot) utility provides a solution to make it friendlier to load other Linux kernels on the fly. kboot is designed for a particular purpose, making it friendlier to allow for a faster transition from the currently running kernel to a new kernel, avoiding the time-consuming hardware initialization and bootloader stages. It performs the following steps:
- Reads the settings in the specified configuration file.
- Then, it uses kexec to load the selected kernel using the parameters from the configuration file.
- 🔰 Information: To learn how to use Kernel Boot, see How to use Kernel Boot.
- In kernel-related topics, to manually build kernel modules using dkms, see our tutorial about Building dkms Drivers in Nitrux.
Using VMetal in Nitrux
- VMetal allows users to run Windows in parallel to Nitrux to provide users access to Windows software. Meanwhile, they can still use their Linux desktop at the same time. VMetal uses QEMU and KVM (Kernel-based Virtual Machine) on the software side and VFIO and IOMMU on the hardware side, meaning that Windows directly accesses the hardware it utilizes.
- 🔰 Information: To learn how to use VMetal, see How to use VMetal in Nitrux.
Disclaimer: Due to the magnitude of possible hardware combinations and UEFI firmware versions, we cannot guarantee that a specific hardware combination will work out of the box when using VMetal. We do not possess the means to test or acquire every consumer available product for verification that it will work in VMetal. We have tested VMetal only on the computers we have access to that meet the criteria. Therefore, YMMV. If VMetal works in your hardware configuration, please use hw-probe to let us know what hardware you’ve used.
Installing Hypervisors in Nitrux
- To install hypervisors such as VirtualBox, VMware Workstation products, or GNOME Boxes, see our tutorial about Installing Hypervisors in Nitrux.
- We have discontinued minimal ISO releases of the distribution.
- We have discontinued OVA releases of the distribution.
- Nitrux is exclusively a 64-bit Linux distribution; we do not use, include, or provide support for 32-bit software.
- Nitrux includes a simple text file called installed_pkgs_end.txt in the root directory that, as its name suggests, lists all installed packages by default in the distribution. Users can use it to compare more extensive changes from release to release, like package updates.
- To view the list of packages, use Nota or the command cat. When using cat to look for a specific package, use grep, i.e., search for Mauikit.
cat /installed_pkgs_end.txt cat /installed_pkgs_end.txt | grep mauikit
- Nitrux has various command-line utilities, including a file manager, text editor, web browser, remote desktop, system monitor, and a single game. Below is a list of these command-line utilities.
- ftp, hdparm, htop, links2, mc, micro, ncdu, tmate, tree, and nsnake.
- We recommend users who wish to run prelink manually do it after using overlayroot-chroot; see XFS Features and Root Immutability in Nitrux. To run prelink manually, run the following command.
