UKUI: a Lightweight Desktop Environment Based on Pluggable
2016 International Conference on Artificial Intelligence and Computer Science (AICS 2016) ISBN: 978-1-60595-411-0 UKUI: A Lightweight Desktop Environment Based on Pluggable Framework for Linux Distribution Jie YU1, Lu SI1,*, Jun MA1, Lei LUO1, Xiao-dong LIU1, Ya-ting KUANG2, Huan PENG2, Rui LI1, Jin-zhu KONG2 and Qing-bo WU1 1College of Computer, National University of Defense Technology, Changsha, China 2Tianjin KYLIN Information Technology Co., Ltd, Tianjin, China *[email protected] *Corresponding author Keywords: Desktop environment, Ubuntu, User interface. Abstract. Ubuntu is an operating system with Linux kernel based on Debian and distributed as free and open-source software. It uses Unity as its default desktop environment, which results in more difficulties of usage for Microsoft Windows users. In this paper, we present a lightweight desktop environment named UKUI based on UbuntuKylin, the official Chinese version of Ubuntu, for Linux distribution. It is designed as a pluggable framework and provides better user experience during human-computer interaction. In order to evaluate the performance of UKUI, a set of testing bench suits were performed on a personal computer. Overall, the results showed that UKUI has better performance compared with Unity. Introduction Linux is a freely available operating system (OS) originated by Linux Torvalds and further developed by thousands of others. Typically, Linux is packaged in a form known as a Linux distribution for both desktop and server use. Some of the most popular mainstream Linux distributions are Red Hat [1], Ubuntu [2], Arch [3], openSUSY [4], Gentoo [5], etc. There are several desktop environments available for nowadays modern Linux distributions, such as XFCE [6], GNOME [7], KDE [8] and LXDE [9]. -

The GNOME Desktop Environment
The GNOME desktop environment Miguel de Icaza ([email protected]) Instituto de Ciencias Nucleares, UNAM Elliot Lee ([email protected]) Federico Mena ([email protected]) Instituto de Ciencias Nucleares, UNAM Tom Tromey ([email protected]) April 27, 1998 Abstract We present an overview of the free GNU Network Object Model Environment (GNOME). GNOME is a suite of X11 GUI applications that provides joy to users and hackers alike. It has been designed for extensibility and automation by using CORBA and scripting languages throughout the code. GNOME is licensed under the terms of the GNU GPL and the GNU LGPL and has been developed on the Internet by a loosely-coupled team of programmers. 1 Motivation Free operating systems1 are excellent at providing server-class services, and so are often the ideal choice for a server machine. However, the lack of a consistent user interface and of consumer-targeted applications has prevented free operating systems from reaching the vast majority of users — the desktop users. As such, the benefits of free software have only been enjoyed by the technically savvy computer user community. Most users are still locked into proprietary solutions for their desktop environments. By using GNOME, free operating systems will have a complete, user-friendly desktop which will provide users with powerful and easy-to-use graphical applications. Many people have suggested that the cause for the lack of free user-oriented appli- cations is that these do not provide enough excitement to hackers, as opposed to system- level programming. Since most of the GNOME code had to be written by hackers, we kept them happy: the magic recipe here is to design GNOME around an adrenaline response by trying to use exciting models and ideas in the applications. -

KDE Plasma 5
Arvo Mägi KDE Plasma 5 Tallinn, 2017 1 Sissejuhatus KDE töökeskkonnale pani aluse saksa programmeerija Matthias Ettrich 14.10.1996. 2016. a oktoobris sai populaarne KDE seega 20. aastaseks. Hea ülevaate KDE ajaloost annab artikkel „19 Years of KDE History: Step by Step.” KDE 4.14 ilmumisega oli KDE saavutanud kasutusküpsuse, kuid edasine areng kippus takerduma – vaja oli põhimõttelisi uuendusi. Otsustati võtta kasutusele iseseisvatel moodulitel põhinev KDE 5 arhitektuur – Qt/Frameworks. Kõik KDE rakendusprogrammid, sh Plasma 5 töölaud, kasutavad ainult konkreetse rakenduse jaoks vajalikke mooduleid. Varem kasutati kõigi rakenduste jaoks ühist suurt teeki, mis raskendas muudatuste tegemist ja pidurdas arendustööd. Qt on C++ programmeerimiskeskkond. Pikaajalise toega Qt 5.9 LTS ilmus 31. mail 2017. KDE Frameworks on 70 moodulist koosnev komplekt, mis lihtsustab Qt keskkonnas KDE programmide koostamist. Frameworks veaparandused ja täiendused ilmuvad iga kuu. KDE Plasma 5 töölaud põhineb KDE Frameworksil (KF5). Töölaua veaparandused ilmuvad iga kuu, vajadusel mitu korda kuus, uued versioonid kord kvartalis. Plasma 5.8 LTS, mis on pikaajalise toega (18 kuud), ilmus 4.10.2016, veidi enne KDE 20. aastaseks saamist. Plasma 5.10 ilmus 30.05.2017. Järgmine pikaajalise toega Plasma 5.12 ilmub 2018. a jaanuaris. Plasma 5 töölaud on pälvinud palju kiitvaid hinnanguid ja sobib igapäevaseks tööks. Eeldab kaasaegset, mitme tuumaga protsessori ja piisava mäluga (vähemalt 4 GB) arvutit. SSD kettalt töötab välkkiirelt. Töölaud on keskkond rakendusprogrammide käivitamiseks ja kasutamiseks. KF5-le on üle viidud kõik KDE põhirakendused (failihaldur Dolphin, pildinäitaja Gwenview, konsool Konsole, teksti- redaktor Kate, ekraanitõmmise võtja Spectacle, videoredaktor Kdenlive, plaadikirjutaja K3b jt). Need on KDE Applications koosseisus, mille uued versioonid ilmuvad kolm korda aastas, veaparandused kord kuus. -

Most users are familiar with Windows and OS X. Those operating systems only have one desktop interface. The user can tweak those desktops to a certain extent, but essentially you’re stuck with whatever Apple or Microsoft has decided to do. Menus are always going to be in certain places and key combinations are going to be tied to specific tasks and pro- grams. -

Lumina-DE: Redefining the Desktop Environment for Modern Hardware
Lumina-DE: Redefining the Desktop Environment for Modern Hardware Author: Ken Moore [email protected] PC-BSD/iXsystems Lumina Desktop source repository: https://github.com/pcbsd/lumina Date: Nov 2014 Abstract: As computers continue to advance into every aspect of our daily lives through the pervasiveness of cell phones and tablets, the traditional “desktop computer” is gradually being shifted to a smaller subset of the total systems in use. This presents a problem for open source operating systems, as the available open source graphical environments are increasingly designed for systems with powerful hardware or traditional mouse/keyboard inputs – resulting in a much lower percentage of devices that are physically capable of utilitizing the OS. The open-source Lumina desktop environment is designed to solve these problems by meeting its goals of being a highly flexible and scalable interface that runs with relatively little hardware requirements. The project also provides a simple framework for integrating OS-specific functionality directly into the interface for ease-of-use without causing conflict with the underlying system or affecting portability. This paper will take a top-level view of the Lumina desktop project, breaking it down to its components, explaining the framework and methodology, and listing the work that is still yet to be completed to achieve its goals. Please note: for all intents and purposes, there is no distinction between laptops and box-based desktop computers when it comes to the capabilities and distinctions of a graphical interface, so for the purposes of this paper they will both be considered “desktop” systems. The Problem: Smartphones, tablets, laptops and desktop computers all utilitize graphical interfaces to provide the user access to the capabilities of the device, but laptops and desktop computers are the only ones with fully open source desktop environments available. -
