PureOS is a Linux distribution focusing on privacy and security, using the GNOME or KDE Plasma desktop environment. [2] [3] [4] It is maintained by Purism for use in the company's Librem laptop computers as well as the Librem 5 smartphone. [5] [6]
PureOS is designed to include only free software, and is included in the list of Free Linux distributions published by the Free Software Foundation. [7] [8]
PureOS is a Debian-based Linux distribution, merging open-source software packages from the Debian “testing” main archive using a hybrid point release and rolling release model. [9] The default web browser in PureOS is GNOME Web. [10] The default search engine is DuckDuckGo.
Debian, is a Linux distribution composed of free and open-source software and proprietary software developed by the community-supported Debian Project, which was established by Ian Murdock on August 16, 1993. The first version of Debian (0.01) was released on September 15, 1993, and its first stable version (1.1) was released on June 17, 1996. The Debian Stable branch is the most popular edition for personal computers and servers. Debian is also the basis for many other distributions that have different purposes, like Proxmox for servers, Ubuntu or Linux Mint for desktops, Kali for penetration testing or Pardus and Astra for government use.
A Linux distribution is an operating system made from a software collection that includes the Linux kernel and often a package management system. Linux users usually obtain their operating system by downloading one of the Linux distributions, which are available for a wide variety of systems ranging from embedded devices and personal computers to powerful supercomputers.
A light-weight Linux distribution is one that uses lower memory and/or has less processor-speed requirements than a more "feature-rich" Linux distribution. The lower demands on hardware ideally result in a more responsive machine, and/or allow devices with fewer system resources to be used productively. The lower memory and/or processor-speed requirements are achieved by avoiding software bloat, i.e. by leaving out features that are perceived to have little or no practical use or advantage, or for which there is no or low demand.
Linux is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution (distro), which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses and recommends the name "GNU/Linux" to emphasize the use and importance of GNU software in many distributions, causing some controversy.
gNewSense was a Linux distribution, active from 2006 to 2016. It was based on Debian, and developed with sponsorship from the Free Software Foundation. Its goal was user-friendliness, but with all proprietary and non-free software removed. The Free Software Foundation considered gNewSense to be composed entirely of free software.
GNU variants are operating systems based upon the GNU operating system. According to the GNU project and others, these also include most operating systems using the Linux kernel and a few others using BSD-based kernels.
According to the Free Software Foundation Latin America, Linux-libre is a modified version of the Linux kernel that contains no binary blobs, obfuscated code, or code released under proprietary licenses. In the Linux kernel, they are mostly used for proprietary firmware images. While generally redistributable, binary blobs do not give the user the freedom to audit, modify, or, consequently, redistribute their modified versions. The GNU Project keeps Linux-libre in synchronization with the mainline Linux kernel.
Besides the Linux distributions designed for general-purpose use on desktops and servers, distributions may be specialized for different purposes including computer architecture support, embedded systems, stability, security, localization to a specific region or language, targeting of specific user groups, support for real-time applications, or commitment to a given desktop environment. Furthermore, some distributions deliberately include only free software. As of 2015, over four hundred Linux distributions are actively developed, with about a dozen distributions being most popular for general-purpose use.
Linux for mobile devices, sometimes referred to as mobile Linux, is the usage of Linux-based operating systems on portable devices, whose primary or only Human interface device (HID) is a touchscreen. It mainly comprises smartphones and tablet computers, but also some mobile phones, personal digital assistants (PDAs) portable media players that come with a touchscreen separately.
Librem is a line of computers manufactured by Purism, SPC featuring free (libre) software. The laptop line is designed to protect privacy and freedom by providing no non-free (proprietary) software in the operating system or kernel, avoiding the Intel Active Management Technology, and gradually freeing and securing firmware. Librem laptops feature hardware kill switches for the microphone, webcam, Bluetooth and Wi-Fi.
Purism, SPC is an American computer technology corporation based in San Francisco, California and registered in the state of Washington.
Fractal is an instant messaging client and collaboration software for the GNOME desktop based on the Matrix protocol.
Phosh is a graphical user interface designed for mobile and touch-based devices and developed by Purism. It is the default shell used on several mobile Linux operating systems including PureOS, Mobian, and Fedora Mobility. It is also an option on postmarketOS, Manjaro, and openSUSE.
The Librem 5 is a smartphone manufactured by Purism that is part of their Librem line of products. The phone is designed with the goal of using free software whenever possible, includes PureOS, a Linux operating system, by default, and as of 2021 is the only smartphone recommended by the Free Software Foundation. Like other Librem products, the Librem 5 focuses on privacy and freedom, and includes features like hardware kill switches, and easily-replaceable components. Its name, with a numerical "5", refers to its screen size, and not a release version. After an announcement on 24 August 2017, the distribution of developer kits and limited pre-release models occurred throughout 2019 and most of 2020. The first mass-production version of the Librem 5 was shipped on 18 November 2020.
The PinePhone is a smartphone developed by Hong Kong-based computer manufacturer Pine64, intended to allow the user to have full control over the device. Measures to ensure this are: running mainline Linux-based mobile operating systems, assembling the phone with screws, and simplifying the disassembly for repairs and upgrades. LTE, GPS, Wi-Fi, Bluetooth and both cameras can be physically switched off. The PinePhone ships with the Manjaro Linux-based operating system using the Plasma Mobile graphic interface, although other distributions can be installed by users.
The scope for this page is that used for list of open-source mobile phones.
Mobian is a project to add support to standard Debian Linux distribution with mainline Linux kernel on smartphones and tablets. The project was announced 2020. Project is publishing install images for PinePhone, PineTab, Librem 5 and for Android devices, with mainline kernel support, OnePlus 6/6T and Pocophone F1. Droidian version uses Mobian on top of Android kernel and Libhybris and Halium adaptation layer and works with devices which are supported by Ubuntu Touch and it can be installed using Ubports installer.
