X Display Manager (implementation)
The X Display Manager (XDM) is the default display manager for the X Window System. It is a bare-bones X display manager. It was introduced with X11 Release 3 in October 1988, to support the standalone X terminals that were just coming onto the market. It was written by Keith Packard. Functions XDM is used to boot an X.org based desktop environment In computing, a desktop environment (DE) is an implementation of the desktop metaphor made of a bundle of programs running on top of a computer operating system that share a common graphical user interface (GUI), sometimes described as a graphi .... It can control a display directly or indirectly in order to start an X session and supports remote login. XDM is initialized on system startup. It can be edited through the use of a configuration file, modules, or scripts. The configuration file is usually found in /usr/lib/X11/xdm/xdm-config. History XDM is one of the earliest display managers for Linux. It was developed by K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

XPath 2
XPath 2.0 is a version of the XPath language defined by the World Wide Web Consortium, W3C. It became a recommendation on 23 January 2007. As a W3C Recommendation it was superseded by XPath 3.0 on 10 April 2014. XPath is used primarily for selecting parts of an XML document. For this purpose the XML document is modelled as a tree of nodes. XPath allows nodes to be selected by means of a hierarchic navigation path through the document tree. The language is significantly larger than its predecessor, XPath 1.0, and some of the basic concepts such as the data model and type system have changed. The two language versions are therefore described in separate articles. XPath 2.0 is used as a sublanguage of XSLT 2.0, and it is also a subset of XQuery 1.0. All three languages share the same data model (the XDM), type system, and function library, and were developed together and published on the same day. Data model Every value in XPath 2.0 is a ''sequence'' of ''items''. The item ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Desktop Environment
In computing, a desktop environment (DE) is an implementation of the desktop metaphor made of a bundle of programs running on top of a computer operating system that share a common graphical user interface (GUI), sometimes described as a graphical shell. The desktop environment was seen mostly on personal computers until the rise of mobile computing. Desktop GUIs help the user to easily access and edit files, while they usually do not provide access to all of the features found in the underlying operating system. Instead, the traditional command-line interface (CLI) is still used when full control over the operating system is required. A desktop environment typically consists of icons, windows, toolbars, directory (file systems), folders, computer wallpaper, wallpapers and Widget engine, desktop widgets (see Elements of graphical user interfaces and WIMP_(computing), WIMP). A GUI might also provide drag and drop functionality and other features that make the desktop metaphor mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Software Using The MIT License
Software consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware. The introduction of high-level programming languages in 1958 allowed for more human-readable instructions, making software development easier and more portable across different computer architectures. Software in a programming language is run through a compiler or interpreter to execute on the architecture's hardware. Over time, software has become complex, owing to developments in networking, operating systems, and databases. Software can generally be categorized into two main types: # operating systems, which manage hardware resources and provide services for applications # application software, which performs specific tasks for users The rise of cl ...

KDE Display Manager
KDE Display Manager (KDM) was a display manager (a graphical login program) developed by KDE for the windowing systems X11. KDE Display Manager was based on the source code of X display manager and was the default display manager of the KDE Software Compilation, until it was retired in KDE Plasma 5 in favour of SDDM. KDM allowed the user to choose a desktop environment or window manager at login. KDM used the Qt application framework. It is configurable via KDE's System Settings; its appearance can be customized by the user. The default KDM login screen had a list of users. Each entry was comprised in the user's username, personal name (if available), and an icon. Next to the list is a greeting and a picture. One of the customization options is to replace the picture with an analog clock. From this screen the user can also run a user management tool, shut down or reboot the computer, or restart the X Window System. See also * getty – a non-graphical login program * Sim ...

GNOME Display Manager
GNOME Display Manager (GDM) is a display manager (a graphical login manager) for the windowing systems X11 and Wayland. The X Window System by default uses the XDM display manager. However, resolving XDM configuration issues typically involves editing a configuration file. GDM allows users to customize or troubleshoot settings without having to resort to a command line. Users can pick their session type on a per-login basis. GDM 2.38.0 is the last version that features customization with themes; subsequent releases do not support themes. Software architecture GDM is a display manager that implements all significant features required for managing attached and remote displays. GDM was written from scratch and does not contain any XDM or X Consortium code. Components GDM comprises the following components: * Chooser – a program used to select a remote host as the source for a remote display on the attached display (gdm-host-chooser) * Greeter – the graphical login wind ...

Common Desktop Environment
The Common Desktop Environment (CDE) is a desktop environment for Unix and OpenVMS, based on the Motif (software), Motif widget toolkit. It was part of the UNIX 98, UNIX 98 Workstation Product Standard, and was for a long time the Unix desktop associated with commercial Unix workstations. It helped to influence early implementations of successor projects such as KDE and GNOME, which largely replaced CDE following the turn of the century. After a long history as proprietary software, CDE was released as free software on August 6, 2012, under the GNU Lesser General Public License, version 2.0 or later. Since its release as free software, CDE has been ported to Linux and BSD derivatives. History Hewlett-Packard, IBM, SunSoft, Inc., SunSoft, and Unix System Laboratories, USL announced CDE in June 1993 as a joint development within the Common Open Software Environment (COSE) initiative. Each development group contributed its own technology to CDE: * HP contributed the primary envi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

XSLT 2
XSLT (Extensible Stylesheet Language Transformations) is a language originally designed for transforming XML documents into other XML documents, or other formats such as HTML for web pages, plain text, or XSL Formatting Objects. These formats can be subsequently converted to formats such as PDF, PostScript, and PNG. Support for JSON and plain-text transformation was added in later updates to the XSLT 1.0 specification. XSLT 3.0 implementations support Java, .NET, C/C++, Python, PHP and NodeJS. An XSLT 3.0 JavaScript library can also be hosted within the web browser. Modern web browsers also include native support for XSLT 1.0. The XSLT document transformation specifies how to transform an XML document into new document (usually XML, but other formats, such as plain text are supported). Typically, input documents are XML files, but anything from which the processor can build an XQuery and XPath Data Model can be used, such as relational database tables or geographical informatio ...

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 ...
