Linux-based devices or Linux devices are computer appliances that are powered by the Linux kernel and possibly parts of the GNU operating system. Device manufacturers' reasons to use Linux may be various: low cost, security, stability, scalability or customizability. Many original equipment manufacturers use free and open source software to brand their products. Community maintained Linux devices are also available.
KDE Plasma 4 is the fourth generation of the KDE workspace environments. It consists of three workspaces, each targeting a certain platform: Plasma Desktop for traditional desktop PCs and notebooks, Plasma Netbook for netbooks, and Plasma Active for tablet PCs and similar devices.
A mobile operating system is an operating system used for smartphones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as typical/mobile laptops are "mobile", the operating systems used on them are generally not considered mobile, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This line distinguishing mobile and other forms has become blurred in recent years, due to the fact that newer devices have become smaller and more mobile unlike hardware of the past. Key notabilities blurring this line are the introduction of tablet computers, light laptops, and the hybridization of the two in 2-in-1 PCs.
Mer was a free and open-source software distribution, targeted at hardware vendors to serve as a middleware for Linux kernel-based mobile-oriented operating systems. It is a fork of MeeGo.
Sailfish OS is a paid Linux-based operating system based on free software, and open source projects such as Mer as well as including a closed source UI. The project is being developed by the Finnish company Jolla.
Maliit is an input method framework for computers with particular focus on implementing virtual keyboards. Designed mostly for touchscreen devices, Maliit allows the inputting of text without the presence of a physical keyboard. More advanced features such as word correction and prediction are also available.
The Nokia Asha platform is a discontinued mobile operating system (OS) and computing platform designed for low-end borderline smartphones, based on software from Smarterphone which was acquired by Nokia. The platform inherits UI similarities mostly from MeeGo "Harmattan", and replaced Series 40 on Nokia's low-end devices. The user interface design team was headed by Peter Skillman, who had worked previously on webOS and the design of MeeGo for the Nokia N9.
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.
PureOS is a Linux distribution focusing on privacy and security, using the GNOME or KDE Plasma desktop environment. It is maintained by Purism for use in the company's Librem laptop computers as well as the Librem 5 smartphone.
postmarketOS is an operating system primarily for smartphones, based on the Alpine Linux distribution.
/e/ is a fork of LineageOS, an Android-based mobile operating system, and associated online services. /e/ is presented as privacy software that does not contain proprietary Google apps or services, and challenges the public to "find any parts of the system or default applications that are still leaking data to Google."
Halium is a collaborative project to unify the Hardware Abstraction Layer for projects which run Linux on mobile devices with pre-installed Android. The project aims to standardize the middleware software used by various projects to talk with android daemons and make use of hardware on installed devices. It is distributed as free and open-source software under a mix of software licenses.
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 Phosh. 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, and includes PureOS, a Linux operating system, by default. As of 2021, it 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 operating system using the Plasma Mobile graphic interface, although other distributions can be installed by users.
Plasma Mobile is a Plasma variant for smartphones. It is currently available for the Pinephone, and supported devices for postmarketOS such as the OnePlus 6.
Garuda Linux is a Linux distribution targeted towards gaming based on Arch Linux. It is available in multiple desktop environments, but the KDE Plasma version is the main one. The term Garuda, originating from Hinduism and Buddhism, is defined as a divine eagle-like sun bird and the king of birds.
