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 related ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wayland (protocol)
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 mov ...

English Language
English is a West Germanic language that developed in early medieval England and has since become a English as a lingua franca, global lingua franca. The namesake of the language is the Angles (tribe), Angles, one of the Germanic peoples that Anglo-Saxon settlement of Britain, migrated to Britain after its End of Roman rule in Britain, Roman occupiers left. English is the list of languages by total number of speakers, most spoken language in the world, primarily due to the global influences of the former British Empire (succeeded by the Commonwealth of Nations) and the United States. English is the list of languages by number of native speakers, third-most spoken native language, after Mandarin Chinese and Spanish language, Spanish; it is also the most widely learned second language in the world, with more second-language speakers than native speakers. English is either the official language or one of the official languages in list of countries and territories where English ...

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 ...

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 ...

Vulkan
Vulkan is a cross-platform API and open standard for 3D graphics and computing. It was intended to address the shortcomings of OpenGL, and allow developers more control over the GPU. It is designed to support a wide variety of GPUs, CPUs and operating systems, and it is also designed to work with modern multi-core CPUs. Microsoft supports Vulkan 1.2 (and more) on Windows 10 and 11, with a downloadable compatibility pack. Overview Vulkan targets high-performance real-time 3D-graphics applications, such as video games and interactive media, and highly parallelized computing. Vulkan is intended to offer higher performance and more efficient CPU and GPU usage compared to the older OpenGL and Direct3D 11 APIs. It does so by providing a considerably lower-level API for the application than the older APIs, that more closely resembles how modern GPUs work. Vulkan is comparable to Apple's Metal API and Microsoft's Direct3D 12. In addition to its lower CPU usage, Vulkan is design ...

Generic Buffer Management
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 ...

EGL (API)
EGL is an interface between Khronos rendering APIs (such as OpenGL, OpenGL ES or OpenVG) and the underlying native platform windowing system. EGL handles graphics context management, surface/ buffer binding, rendering synchronization, and enables "high-performance, accelerated, mixed-mode 2D and 3D rendering using other Khronos APIs." EGL is managed by the non-profit technology consortium Khronos Group. The acronym ''EGL'' is an initialism, which starting from EGL version 1.2 refers to ''Khronos Native Platform Graphics Interface''. Prior to version 1.2, the name of the EGL specification was ''OpenGL ES Native Platform Graphics Interface''. X.Org development documentation glossary defines EGL as "Embedded-System Graphics Library". Adoption * The BlackBerry 10 and BlackBerry Tablet OS mobile device operating system uses EGL for 3D graphics rendering. Both support EGL version 1.4. * The Android mobile device operating system uses EGL for 3D graphics rendering. * The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
