Xinit
The xinit program allows a user to manually start an X display server. The startx script is a front-end for xinit. By default, xinit and startx start an X display server pointing to a display device that is enumerated as :0 and then start an xterm on it. When the xterm terminates, xinit and startx kill the X display server. In general, xinit and startx can start an arbitrary server and run an arbitrary script. Typically, this script runs a number of programs and a window manager. Two alternative methods for starting an X display server are by using a display manager and by starting the X server and then manually starting one or more clients.

C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

Front And Back Ends
In software development, frontend refers to the presentation layer that users interact with, while backend involves the data management and processing behind the scenes, and full-stack development refers to mastering both. In the client–server model, the client is usually considered the frontend, handling user-facing tasks, and the server is the backend, managing data and logic. Some presentation tasks may also be performed by the server. Introduction In software architecture, there may be many layers between the hardware and end user. The ''front'' is an abstraction, simplifying the underlying component by providing a user-friendly interface, while the ''back'' usually handles data storage and business logic. Examples E-commerce Website: The ''frontend'' is the user interface (e.g., product pages, search bar), while the ''backend'' processes payments and updates inventory. Banking App: The ''frontend'' displays account balances, while the ''backend'' handles secure tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Display Device
A display device is an output device for presentation of information in visual or tactile form (the latter used for example in tactile electronic displays for blind people). When the input information that is supplied has an electrical signal the display is called an '' electronic display''. Common applications for ''electronic visual displays'' are television sets or computer monitors. Types of electronic displays In use These are the technologies used to create the various displays in use today. * Liquid-crystal display (LCD) ** Light-emitting diode (LED) backlit LCD ** Thin-film transistor (TFT) LCD ** Quantum dot (QLED) display * Light-emitting diode (LED) display ** OLED display ** AMOLED display ** Super AMOLED display Segment displays Some displays can show only digits or alphanumeric characters. They are called segment displays, because they are composed of several segments that switch on and off to give appearance of desired glyph. The segments ...

Xterm
xterm is the standard terminal emulator for the X Window System. It allows users to run programs which require a command-line interface. If no particular program is specified, xterm runs the user's Unix shell, shell. An X display device, display can show one or more user's xterm windows input/output, output at the same time. Each xterm window is a separate Process (computing), process, but all share the same Computer keyboard, keyboard, taking turns as each xterm process acquires Focus (computing), ''focus''. Normally focus switches between X applications as the user moves the pointer (e.g., a mouse cursor) about the screen, but xterm provides options to ''grab focus'' (the ''Secure Keyboard'' feature) as well as accept input events sent without using the keyboard (the ''Allow SendEvents'' feature). Those options have limitations, as discussed in the xterm manual. XTerm originated prior to the X Window System. It was originally written as a stand-alone terminal emulator for ...

X Window Manager
An X window manager is a window manager that runs on top of the X Window System, a windowing system mainly used on Unix-like systems. Unlike MacOS Classic, macOS, and Microsoft Windows platforms (excepting Microsoft Windows explorer.exe shell replacements), which have historically provided a vendor-controlled, fixed set of ways to control how windows and panes display on a screen, and how the user may interact with them, window management for the X Window System was deliberately kept separate from the software providing the graphical display. The user can choose between various third-party window managers, which differ from one another in several ways, including: * customizability of appearance and functionality: ** textual menus used to start programs and/or change options ** docks and other graphical ways to start programs ** multiple desktops and virtual desktops (desktops larger than the physical monitor size), and pagers to switch between them * consumption of memor ...

X Display Manager (program Type)
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 works ...

Desktop Linux
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. , over four hundred Linux distributions are actively developed, with about a dozen distributions being most popular for general-purpose use. Desktop The popularity of Linux on standard desktop computers and laptops has been increasing over the years. Most modern distributions include a graphical user environment, with, , the three most popular environments being the KDE Plasma Desktop, Xfce and GNOME. No single official Linux desktop exists: rather desktop environments and Linux distributions select components from a pool ...
