LXQt
LXQt is a free and open source lightweight desktop environment. It was formed from the merger of the LXDE and Razor-qt projects. Like its GTK predecessor LXDE, LXQt does not ship or develop its own window manager, instead LXQt lets the user decide which (supported) window manager they want to use. Linux distributions commonly default LXQt to Openbox or xfwm4 or kwin. History Dissatisfied with GTK 3, LXDE maintainer Hong Jen Yee experimented with Qt in early 2013 and released the first version of a Qt-based PCMan File Manager on 26 March 2013. He clarified, though, that this means no departure from GTK in LXDE, saying "The GTK and Qt versions will coexist". He later ported LXDE's Xrandr front-end to Qt. On 3 July 2013 Hong Jen Yee announced a Qt port of the full LXDE suite, and on 21 July 2013, Razor-qt and LXDE announced that they had decided to merge the two projects. This merge meant that the GTK and the Qt versions coexisted in the short term, but eventually devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Razor-qt
Razor-qt is a discontinued free and open-source desktop environment. It was intended as a lightweight desktop environment based upon the Qt application framework, and was "tailored for users who value simplicity, speed, and an intuitive interface." Development of Razor-qt has ceased, as it has merged with LXDE's Qt port to form LXQt. Overview Razor-qt was still in the early stages of development. , the environment included a panel viewer and switcher, a desktop, an application launcher, a settings center and sessions. These components could be enabled or disabled by the user. Razor-qt could be used with any modern X window manager such as Openbox, fvwm2, or KWin. The memory consumption of Razor-qt was slightly above LXDE, using 114 MiB in a reviewer's test while LXDE used 108 MiB. Merge with LXDE After LXDE developer Hong Jen Yee ported PCManFM to Qt in early 2013, he and other interested developers discussed a potential collaboration with Razor-qt, another open-so ...

LXDE
LXDE (abbreviation for Lightweight X11 Desktop Environment) is a free desktop environment with comparatively low resource requirements. This makes it especially suitable for use on older or resource-constrained personal computers such as netbooks or system on a chip computers. Overview LXDE is written in the C programming language, using the GTK 2 toolkit, and runs on Unix and other POSIX-compliant platforms, such as Linux and BSDs. The LXDE project aims to provide a fast and energy-efficient desktop environment. In 2010, tests suggested that LXDE 0.5 had the lowest memory-usage of the four most-popular desktop environments of the time (the others being GNOME 2.29, KDE Plasma Desktop 4.4, and Xfce 4.6), and that it consumed less energy, which suggests mobile computers with Linux distributions running LXDE 0.5 drained their batteries at a slower pace than those with other desktop environments. LXDE uses rolling releases for its individual components (or for groups of co ... [...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. See also * GDM, the default graphical login program of GNOME * LightDM, formerly the default graphical login program of Ubuntu Ubuntu ( ) is a Linux distribution based on Debian and composed mostly of free and open-source software.

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, folders, wallpapers and desktop widgets (see Elements of graphical user interfaces and WIMP). A GUI might also provide drag and drop functionality and other features that make the desktop metaphor more complete. A desktop environment aims to be an intuitive way for the user ...

PCMan File Manager
PCMan File Manager (PCManFM) is a file manager application, developed by Hong Jen Yee () from Taiwan, which is meant to be a replacement for GNOME Files, Dolphin (file manager), Dolphin and Thunar. PCManFM is the standard file manager in LXDE, also developed by the same author in conjunction with other developers. Since 2010, PCManFM has undergone a complete rewrite from scratch; build instructions, setup and configuration have changed in the process. Released under the GNU General Public License, PCManFM is free software. It follows the specifications given by Freedesktop.org for interoperability. Dissatisfied with GTK, GTK3, Hong Jen Yee experimented with Qt (framework), Qt in early 2013 and released the first version of a Qt-based PCManFM on . He clarified, though, that does not indicate any departure from GTK in LXDE, saying: "The GTK and Qt versions will coexist". The new PCManFM-Qt is a core component of LXQt. In 2020 the Arch Linux community ported PCManFM to GTK 3. Featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Qt (software)
Qt (pronounced "cute") is cross-platform software for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed. Qt is currently being developed by The Qt Company, a publicly listed company, and the Qt Project under open-source governance, involving individual developers and organizations working to advance Qt. Qt is available under both commercial licenses and open-source GPL 2.0, GPL 3.0, and LGPL 3.0 licenses. Purposes and abilities Qt is used for developing graphical user interfaces (GUIs) and multi-platform applications that run on all major desktop platforms and most mobile or embedded platforms. Most GUI programs created with Qt have a native-looking interface, in which case Qt is classified as a '' widget tool ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dialog Box
The dialog box (also called dialogue box (non-U.S. English), message box or simply dialog) is a graphical control element in the form of a small window that communicates information to the user and prompts them for a response. Dialog boxes are classified as " modal" or "modeless", depending on whether they block interaction with the software that initiated the dialog. The type of dialog box displayed is dependent upon the desired user interaction. The simplest type of dialog box is the alert, which displays a message and may require an acknowledgment that the message has been read, usually by clicking "OK", or a decision as to whether or not an action should proceed, by clicking "OK" or "Cancel". Alerts are also used to display a "termination notice"—sometimes requesting confirmation that the notice has been read—in the event of either an intentional closing or unintentional closing (" crash") of an application or the operating system. (E.g., "Gedit has encounte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Viewer
An image viewer or image browser is a computer program that can display stored graphical images; it can often handle various graphics file formats. Such software usually renders the image according to properties of the display such as color depth, display resolution, and color profile. Although one may use a full-featured raster graphics editor (such as Photoshop or GIMP) as an image viewer, these have many editing functionalities which are not needed for just viewing images, and therefore usually start rather slowly. Also, most viewers have functionalities that editors usually lack, such as stepping through all the images in a directory (possibly as a slideshow). Image viewers give maximal flexibility to the user by providing a direct view of the directory structure available on a hard disk. Most image viewers do not provide any kind of automatic organization of pictures and therefore the burden remains on the user to create and maintain their folder structure (using tag- or fo ...

Freedesktop
freedesktop.org (fd.o) is a project to work on interoperability and shared base technology for Free software, free-software desktop environments for the X Window System (X11) and Wayland (display server protocol), Wayland on Linux and other Unix-like operating systems. It was founded by Havoc Pennington, a GNOME developer working for Red Hat in March 2000. The project's servers are hosted by Portland State University, sponsored by Hewlett-Packard, Intel, and Google. Widely used open-source software, open-source X-based desktop projects, such as GNOME, KDE Plasma 5, KDE's Plasma Desktop, and Xfce, are collaborating with the freedesktop.org project. In 2006, the project released Portland Project, Portland 1.0 (xdg-utils), a set of common interfaces for desktop environments. However, freedesktop.org is a "collaboration zone" for standards and specifications where users can freely discuss ideas, and not a formal standards organization. freedesktop.org was formerly known as the X De ...

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer 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 CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. 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 measuring programming language popularity, most widely used programming languages, with C compilers avail ...

RandR
X.Org Server is the free and open-source implementation of the X Window System 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 server side ...
