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 for managing a display remotely on the attached display (gdm-host-chooser) * Greeter – the graphical login window ( ...

Dark Theme
A light-on-dark color scheme —also called black mode, dark mode, dark theme, night mode, or lights-out (mode)— is a color scheme that uses light-colored text, icons, and graphical user interface elements on a dark background. It is often discussed in terms of computer user interface design and web design. Many modern websites and operating systems offer the user an optional light-on-dark display mode. Some users find dark mode displays more visually appealing, and claim that it can reduce eye strain. Displaying white on full brightness uses roughly six times as much power as pure black on a 2016 Google Pixel, which has an OLED display. However conventional LED displays cannot benefit from reduced power consumption. Most modern operating systems support an optional light-on-dark color scheme. History Predecessors of modern computer screens, such as cathode-ray oscillographs, oscilloscopes, etc., tended to plot graphs and introduce other content as glowing traces on a bl ...

Login Session
In computing, a login session is the period of activity between a user logging in and logging out of a (multi-user) system. On Unix and Unix-like operating systems, a login session takes one of two main forms: * When a textual user interface is used, a login session is represented as a kernel session — a collection of process groups with the logout action manage * On Windows NT-based systems, login sessions are maintained by the kernel and control of them is within the purview of the Local Security Authority Subsystem Service (LSA). winlogon responds to the secure attention key, it requests the LSA to create login sessions on login, and terminates all of the processes belonging to a login session on logout.

KDE Plasma 4
KDE Plasma 4 was the fourth generation of the KDE workspace environments. It consisted 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. KDE Plasma 4 was released as part of KDE Software Compilation 4 and replaced Kicker, KDesktop, and SuperKaramba, which formed the Desktop in earlier KDE releases. They are bundled as the default environment with a number of free software operating systems, such as Chakra, Kubuntu, Mageia (DVD version), openSUSE, or TrueOS. With the release of KDE SC 4.11 on 14 August 2013, KDE Plasma 4 was placed into a feature freeze and turned into a long-term stable package until August 2015. On 15 July 2014 KDE Plasma 4's successor, KDE Plasma 5, was released. Features Plasma features ''containments'', which are essentially applets that contain other applets. Two examples of containments are the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KDE Display Manager
KDE Display Manager (KDM) is 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 ...

KDE Plasma 5
KDE Plasma 5 is the fifth and current generation of the graphical workspaces environment created by KDE primarily for Linux systems. KDE Plasma 5 is the successor of KDE Plasma 4 and was first released on 15 July 2014. It includes a new default theme, known as "Breeze", as well as increased convergence across different devices. The graphical interface was fully migrated to QML, which uses OpenGL for hardware acceleration, which resulted in better performance and reduced power consumption. Plasma Mobile is a Plasma 5 variant for Linux-based smartphones. Overview Software architecture KDE Plasma 5 is built using Qt 5 and KDE Frameworks 5, predominantly plasma-framework. It improves support for HiDPI displays and ships a convergable graphical shell, which can adjust itself according to the device in use. 5.0 also includes a new default theme, dubbed Breeze. Qt 5's QtQuick 2 uses a hardware-accelerated OpenGL( ES) scene graph (canvas) to compose and render graphics on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simple Desktop Display Manager
Simple Desktop Display Manager (SDDM) is a display manager (a graphical login program and session manager) for the X11 and Wayland windowing systems. SDDM was written from scratch in C++11 and supports theming via QML. SDDM is free and open-source software subject to the terms of the GNU General Public License version 2 or later. Adoption In 2013, Fedora KDE members decided to default to SDDM in Fedora 21. KDE chose SDDM to be the successor of the KDE Display Manager for KDE Plasma 5. The LXQt developers recommend SDDM as a display manager.

Getty (Unix)
getty, short for "get tty", is a Unix program running on a host computer that manages physical or virtual terminals (TTYs). When it detects a connection, it prompts for a username and runs the 'login' program to authenticate the user. Originally, on traditional Unix systems, getty handled connections to serial terminals (often Teletype machines) connected to a host computer. The ''tty'' part of the name stands for ''Teletype'', but has come to mean any type of text terminal. One ''getty'' process serves one terminal. In some systems, for example, Solaris, ''getty'' was replaced by ttymon. Personal computers running Unix-like operating systems, even if they do not provide any remote login services, may still use ''getty'' as a means of logging in on a local virtual console. Instead of the ''login'' program, ''getty'' may also be set up by the system administrator to run any other program, for example pppd ( point-to-point protocol daemon) to provide a dial-up Internet connect ...

Acts Of Union 1707
The Acts of Union ( gd, Achd an Aonaidh) were two Acts of Parliament: the Union with Scotland Act 1706 passed by the Parliament of England, and the Union with England Act 1707 passed by the Parliament of Scotland. They put into effect the terms of the Treaty of Union that had been agreed on 22 July 1706, following negotiation between commissioners representing the parliaments of the two countries. By the two Acts, the Kingdom of England and the Kingdom of Scotlandwhich at the time were separate states with separate legislatures, but with the same monarchwere, in the words of the Treaty, "United into One Kingdom by the Name of Great Britain". The two countries had shared a monarch since the Union of the Crowns in 1603, when King James VI of Scotland inherited the English throne from his double first cousin twice removed, Queen Elizabeth I. Although described as a Union of Crowns, and in spite of James's acknowledgement of his accession to a single Crown, England and Sc ...

List Of English Monarchs
This list of kings and reigning queens of the Kingdom of England begins with Alfred the Great, who initially ruled Wessex, one of the seven Anglo-Saxon kingdoms which later made up modern England. Alfred styled himself King of the Anglo-Saxons from about 886, and while he was not the first king to claim to rule all of the English, his rule represents the start of the first unbroken line of kings to rule the whole of England, the House of Wessex. Arguments are made for a few different kings thought to have controlled enough Anglo-Saxon kingdoms to be deemed the first king of England. For example, Offa of Mercia and Egbert of Wessex are sometimes described as kings of England by popular writers, but it is no longer the majority view of historians that their wide dominions are part of a process leading to a unified England. Historian Simon Keynes states, for example, that "Offa was driven by a lust for power, not a vision of English unity; and what he left was a reputation, not ...

Easter Egg (media)
File:Carl Oswald Rostosky - Zwei Kaninchen und ein Igel 1861.jpg, 250px, An image that reveals an Easter egg when the hedgehog is clicked or tapped. Another Easter egg can be found in a tooltip when a mouse pointer is hovered over the hedgehog. rect 455 383 550 434 I am a hedgehog, NOT an egg! desc none An Easter egg is a message, image, or feature hidden in software, a video game, a film, or another, usually electronic, medium. The term used in this manner was coined around 1979 by Steve Wright, the then-Director of Software Development in the Atari Consumer Division, to describe a hidden message in the Atari video game ''Adventure'', in reference to an Easter egg hunt. The earliest known video game Easter egg is in '' Moonlander'' (1973), in which the player tries to land a Lunar module on the moon; if the player opts to fly the module horizontally through several of the game's screens, they encounter a McDonald's restaurant, and if they land next to it the astronaut wil ...

X Display Manager Control Protocol
In the X Window System, an X display manager is a graphical login manager which starts a login session on an X server from the same or another computer. A display manager presents the user with a login screen. A session starts when a user successfully enters a valid combination of username and password. When the display manager runs on the user's computer, it starts the X server before presenting the user the login screen, optionally repeating when the user logs out. In this condition, the DM realizes in the X Window System the functionality of and on character-mode terminals. When the display manager runs on a remote computer, it acts like a telnet server, requesting username and password and starting a remote session. X11 Release 3 introduced display managers in October 1988 with the aim of supporting the standalone X terminals, just coming onto the market. Various display managers continue in routine use to provide a graphical login prompt on standalone computer work ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
