Freedesktop
freedesktop.org (fd.o), formerly X Desktop Group (XDG), is a project to work on interoperability and shared base technology for free-software desktop environments for the X Window System (X11) and Wayland on Linux and other Unix-like operating systems. Although freedesktop.org produces specifications for interoperability, it is not a formal standards body. The project was founded by Havoc Pennington, a GNOME developer working for Red Hat in March 2000. Widely used open-source X-based desktop projects, such as GNOME, KDE's Plasma Desktop, and Xfce, are collaborating with the freedesktop.org project. In 2006, the project released Portland 1.0 (xdg-utils), a set of common interfaces for desktop environments. freedesktop.org joined the X.Org Foundation in 2019. Some of the project's servers are hosted by Portland State University. Hosted projects freedesktop.org provides hosting for a number of relevant projects. These include: Windowing system and graphics Software relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wayland Compositor
Wayland is a communication protocol that specifies the communication between a display server and its clients, as well as a C library implementation of that protocol. A display server using the Wayland protocol is called a '' Wayland compositor'', because it additionally performs the task of a compositing window manager. Wayland is developed by a group of volunteers initially led by Kristian Høgsberg as a free and open-source community-driven project with the aim of replacing the X Window System with a secure and simpler windowing system for Linux and other Unix-like operating systems. The project's source code is published under the terms of the MIT License, a permissive free software licence. As part of its efforts, the Wayland project also develops a implementation of a Wayland compositor called ''Weston''. Overview The Wayland Display Server project was started by Red Hat developer Kristian Høgsberg in 2008. Beginning around 2010, Linux desktop graphics have moved ...

Mesa 3D
Mesa, also called Mesa3D and The Mesa 3D Graphics Library, is an open-source software, open source implementation of OpenGL, Vulkan, and other graphics API specifications. Mesa translates these specifications to vendor-specific graphics hardware drivers. Its most important users are two graphics drivers mostly developed and funded by Intel and AMD for their respective hardware (AMD promotes their Mesa drivers Radeon and RadeonSI over the deprecated AMD Catalyst, and Intel has only supported the Mesa driver). Proprietary graphics drivers (e.g., Nvidia GeForce driver and Catalyst) replace all of Mesa, providing their own implementation of a graphics API. An open-source effort to write a Mesa Nvidia driver called Nouveau (software), Nouveau is developed mostly by the community. Besides 3D applications such as games, modern display servers (Glamor (software), X.org's Glamor or Wayland (display server protocol), Wayland's Weston (software), Weston) use OpenGL/EGL (API), EGL; therefor ...

Glamor (software)
X.Org Server is the free and open-source implementation of the X Window System (X11) display server stewarded by the X.Org Foundation. Implementations of the client-side X Window System protocol exist in the form of ''X11 libraries'', which serve as helpful APIs for communicating with the X server. Two such major X libraries exist for X11. The first of these libraries was Xlib, the original C language X11 API, but another C language X library, XCB, was created later in 2001. Other smaller X libraries exist, both as interfaces for Xlib and XCB in other languages, and as smaller standalone X libraries. The services with which the X.Org Foundation supports X Server include the packaging of the releases; certification (for a fee); evaluation of improvements to the code; developing the web site, and handling the distribution of monetary donations. The releases are coded, documented, and packaged by global developers. Software architecture The X.Org Server implements the serv ...

Direct Rendering Infrastructure
The Direct Rendering Infrastructure (DRI) is the framework comprising the modern Linux graphics stack which allows unprivileged user-space programs to issue commands to graphics hardware without conflicting with other programs. The main use of DRI is to provide hardware acceleration for the Mesa implementation of OpenGL. DRI has also been adapted to provide OpenGL acceleration on a framebuffer console without a display server running. DRI implementation is scattered through the X Server and its associated client libraries, Mesa 3D and the Direct Rendering Manager kernel subsystem. All of its source code is open-source software. Overview In the classic X Window System architecture the X Server is the only process with exclusive access to the graphics hardware, and therefore the one which does the actual rendering on the framebuffer. All that X clients do is communicate with the X Server to dispatch rendering commands. Those commands are hardware independent, meani ...

Poppler (software)
Poppler is a free and open-source software library for rendering Portable Document Format (PDF) documents. Its development is supported by freedesktop.org. Commonly used on Linux systems, it powers the PDF viewers of the GNOME and KDE desktop environments. History The project was started by Kristian Høgsberg with two goals: to provide PDF rendering functionality as a shared library, to centralize maintenance effort and to go beyond the goals of Xpdf, and to integrate with functionality provided by modern operating systems. By the version 0.18 release in 2011, the poppler library represented a complete implementation of ISO 32000-1, the PDF format standard, and was the first major free PDF library to support its forms (only Acroforms but not full XFA forms) and annotations features. Poppler is a fork of Xpdf-3.0, a PDF file viewer developed by Derek Noonburg of Glyph and Cog, LLC. The name ''Poppler'' comes from " The Problem with Popplers," an episode of the animated serie ...

X Window System
The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems. X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. The X protocol has been at version 11 (hence "X11") since September 1987. The X.Org Foundation leads the X project, with the current reference implementation, X.Org Server, available as free and open-source software under the MIT License and similar permissive licenses. Purpose and abilities X is an architecture-independent system for remote graphical user interfaces and input device capabilities. Each person using a networked computer terminal, terminal has the ability to interact with the display with any type of user input device. In its standard distribution it is a complete, albeit simple, display and interface solution which delivers a standard widget toolkit, toolkit and protocol stack for building graphical user interfaces on most Unix-like operating syst ...

Video Acceleration API
Video Acceleration API (VA-API) is an open source application programming interface that allows applications such as VLC media player or GStreamer to use hardware video acceleration capabilities, usually provided by the graphics processing unit (GPU). It is implemented by the free and open-source Library (computing), library , combined with a hardware-specific driver, usually provided together with the GPU driver. VA-API video decode/encode interface is platform and window system independent but is primarily targeted at Direct Rendering Infrastructure (DRI) in X Window System on Unix-like operating systems (including Linux, FreeBSD, Solaris (operating system), Solaris), and Android (operating system), Android, however it can potentially also be used with direct framebuffer and graphics sub-systems for video output. Accelerated processing includes support for Video codec, video decoding, video coding, video encoding, subpicture blending, and rendering. The VA-API specification wa ...

Linux Kernel Interfaces
The Linux kernel provides multiple interfaces to User space and kernel space, user-space and kernel-mode code. The interfaces can be classified as either application programming interface (API) or application binary interface (ABI), and they can be classified as either kernel–user space or kernel-internal. Linux API The Linux API includes the kernel–user space API, which allows code in user space to access system resources and services of the Linux kernel. It is composed of the system call interface of the Linux kernel and the subroutines in the C standard library. The focus of the development of the Linux API has been to provide the ''usable features'' of the specifications defined in POSIX in a way which is reasonably compatible, robust and performant, and to provide additional useful features not defined in POSIX, just as the kernel–user space APIs of other systems implementing the POSIX API also provide additional features not defined in POSIX.

Portland Project
The Portland Project is an initiative by freedesktop.org aiming at easing the portability of application software between desktop environments and kernels by designing cross-platform APIs and offering implementations thereof as libraries to independent software vendors (ISVs). The project was taken to establish a greater foothold of Linux and other Unix-like operating systems in the desktop market. It aims at resolving a number of key factors that are believed to reduce the adoption rate of Linux distributions as operating system of choice for desktop computers at home or in the office. While the Tango Desktop Project was started to give users a more unified graphical experience, the Portland Project is intended to ease the porting of desktop applications to Linux for independent software vendors (ISVs). The project goal is to let software developers worry less about the desktop environment a distribution is using, and thus bring it on more common ground with Microsoft Windows and ...
