LXImage-Qt
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 development ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Polkit
Polkit (formerly PolicyKit) is a component for controlling system-wide privileges in Unix-like operating systems. It provides an organized way for non-privileged processes to communicate with privileged ones. Polkit allows a level of control of centralized system policy. It is developed and maintained by David Zeuthen from Red Hat and hosted by the freedesktop.org project. It is published as free software under the terms of version 2 of the GNU Lesser General Public License. Since version 0.105, released in April 2012, the name of the project was changed from ''PolicyKit'' to ''polkit'' to emphasize that the system component was rewritten and that the API had changed, breaking backward compatibility. Fedora became the first distribution to include PolicyKit, and it has since been used in other distributions, including Ubuntu since version 8.04 and openSUSE since version 10.3. Some distributions, like Fedora, have already switched to the rewritten polkit. It is also possible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taskbar
A taskbar is an element of a graphical user interface which has various purposes. It typically shows which programs are currently running. The specific design and layout of the taskbar varies between individual operating systems, but generally assumes the form of a strip located along one edge of the screen. On this strip are various icons which correspond to the windows open within a program. Clicking these icons allow the user to easily switch between programs or windows, with the currently active program or window usually appearing differently from the rest. In more recent versions of operating systems, users can also "pin" programs or files so that they can be accessed quickly, often with a single click. Due to its prominence on the screen, the taskbar usually also has a notification area, which uses interactive icons to display real-time information about the state of the computer system and some of the programs active on it. With the rapid development of operating systems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Openssh
OpenSSH (also known as OpenBSD Secure Shell) is a suite of secure networking utilities based on the Secure Shell (SSH) protocol, which provides a secure channel over an unsecured network in a client–server architecture. Network Working Group of the IETF, January 2006, RFC 4252, The Secure Shell (SSH) Authentication Protocol. OpenSSH started as a fork of the free SSH program developed by Tatu Ylönen; later versions of Ylönen's SSH were proprietary software offered by SSH Communications Security. OpenSSH was first released in 1999 and is currently developed as part of the OpenBSD operating system. OpenSSH is not a single computer program, but rather a suite of programs that serve as alternatives to unencrypted protocols like Telnet and FTP. OpenSSH is integrated into several operating systems, namely Microsoft Windows, macOS and most Linux operating systems, while the portable version is available as a package in other systems. History OpenBSD Secure Shell was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daemon (computing)
In computer multitasking, multitasking computer operating systems, a daemon ( or ) is a computer program that runs as a background process, rather than being under the direct control of an interactive user. Traditionally, the process names of a daemon end with the letter ''d'', for clarification that the process is in fact a daemon, and for differentiation between a daemon and a normal computer program. For example, is a daemon that implements system logging facility, and is a daemon that serves incoming Secure Shell, SSH connections. In a Unix environment, the parent process of a daemon is often, but not always, the init process. A daemon is usually created either by a process Fork (operating system), forking a child process and then immediately exiting, thus causing init to adopt the child process, or by the init process directly launching the daemon. In addition, a daemon launched by forking and exiting typically must perform other operations, such as dissociating the proce ...

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 of ...

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 encountered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freedesktop
freedesktop.org (fd.o) 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. 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 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. 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 Desktop Group, and the abbreviation "XDG" remains common in their work. freedesktop.org joined ...

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 ...

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.
