Picaros Diego Linux for children. here are a few distributions aimed at children: Doudou springs to mind, Tand there’s also Sugar on a Stick.

Part II, Window Managers and Desktop Environments
Part II Window Managers and Desktop Environments The window manager is responsible for managing application windows and application- independent behavior, such as pop-up menus appearing in the background. The window manager manages the placement, borders, and decorations of all windows, and is responsible for the look and feel of your particular X session. Desktop environments typically include an integrated window manager, some sort of control panel, applications, and a consistent look and feel across applications. The chapters in Part II, Window Managers and Desktop Environments, are: Overview This chapter provides a conceptual introduction to window managers and desktop environments and briefly surveys some of the many window managers and desktop environments available for Linux. FVWM FVWM is a traditional window manager for Linux systems. It is now into its second major version, FVWM2. Window Maker Window Maker is an elegant X11 window manager designed to give integration support to GNUstep-based applications. It emulates the look and feel of OpenStep, the NeXTSTEP GUI. Enlightenment Enlightenment, often shortened to just E, may be the most elaborate and bizarre window manager available. Enlightenment’s motto, “time to rethink everything,” provides a good indication of the uniqueness and flashiness behind Enlightenment. Using GNOME GNOME, which stands for GNU Network Object Model Environment, is a freely available desktop environment that can be used with any of several window managers, including Enlightenment and Sawfish. Using KDE KDE, the K Desktop Environment, is another freely available desktop environment. KDE includes an assortment of games and utilities, as well as an integrated suite of office productivity applications.. -
Easy Slackware
1 Создание легкой системы на базе Slackware I - Введение Slackware пользуется заслуженной популярностью как классический linux дистрибутив, и поговорка "кто знает Red Hat тот знает только Red Hat, кто знает Slackware тот знает linux" несмотря на явный снобизм поклонников "бога Патре га" все же имеет под собой основания. Одним из преимуществ Slackware является возможность простого создания на ее основе практически любой системы, в том числе быстрой и легкой десктопной, о чем далее и пойдет речь. Есть дис трибутивы, клоны Slackware, созданные именно с этой целью, типа Аbsolute, но все же лучше создавать систему под себя, с максимальным учетом именно своих потребностей, и Slackware пожалуй как никакой другой дистрибутив подходит именно для этой цели. Легкость и быстрота системы определяется выбором WM (DM) , набором программ и оптимизацией программ и системы в целом. Первое исключает KDE, Gnome, даже новые версии XFCЕ, остается разве что LXDE, но набор программ в нем совершенно не устраивает. Оптимизация наиболее часто используемых про грамм и нескольких базовых системных пакетов осуществляется их сборкой из сорцов компилятором, оптимизированным именно под Ваш комп, причем каж дая программа конфигурируется исходя из Ваших потребностей к ее возможно стям. Оптимизация системы в целом осуществляется ее настройкой согласно спе цифическим требованиям к десктопу. Такой подход был выбран по банальной причине, возиться с gentoo нет ни какого желания, комп все таки создан для того чтобы им пользоваться, а не для компиляции программ, в тоже время у каждого есть минимальный набор из не большого количества наиболее часто используемых программ, на которые стоит потратить некоторое, не такое уж большое, время, чтобы довести их до ума. Кро ме того, такой подход позволяет иметь самые свежие версии наиболее часто ис пользуемых программ. -

An Introduction to the X Window System Introduction to X's Anatomy
An Introduction to the X Window System Robert Lupton This is a limited and partisan introduction to ‘The X Window System’, which is widely but improperly known as X-windows, specifically to version 11 (‘X11’). The intention of the X-project has been to provide ‘tools not rules’, which allows their basic system to appear in a very large number of confusing guises. This document assumes that you are using the configuration that I set up at Peyton Hall † There are helpful manual entries under X and Xserver, as well as for individual utilities such as xterm. You may need to add /usr/princeton/X11/man to your MANPATH to read the X manpages. This is the first draft of this document, so I’d be very grateful for any comments or criticisms. Introduction to X’s Anatomy X consists of three parts: The server The part that knows about the hardware and how to draw lines and write characters. The Clients Such things as terminal emulators, dvi previewers, and clocks and The Window Manager A programme which handles negotiations between the different clients as they fight for screen space, colours, and sunlight. Another fundamental X-concept is that of resources, which is how X describes any- thing that a client might want to specify; common examples would be fonts, colours (both foreground and background), and position on the screen. Keys X can, and usually does, use a number of special keys. You are familiar with the way that <shift>a and <ctrl>a are different from a; in X this sensitivity extends to things like mouse buttons that you might not normally think of as case-sensitive. -

Présentation Ligne De Commande
Kit de survie en lignes de commandes ... pour les nuls. Ceci est la version légèrement corrigée, étendue et complétée de la présentation du jeudi 2 juin 2018. Pourquoi la ligne de commande ? La ligne de commande est une chose qui a, pour des raisons marketting et en lien avec la massification de l'usage de l'outil informatique, peu à peu disparue alors qu'elle faisait partie intégrante des ordinateurs dans les années 80 et jusqu'en 1995 pour le grand public. Actuellement, la ligne de commande est perçue par les néophytes comme un objet de toute puissance ou de diabolisation. Les stéréotypes véhiculés par les media traditionnels associent souvent la ligne de commande, et in extenso le terminal, à un outil de hacker. Alors que cela a été pendant longtemps le quotidien de beaucoup d'utilisateurs. Posons un peu de vocabulaire : Linux est un noyau c'est à dire un binaire qui communique avec le matériel. Autour de lui est le système GNU (pour GNU is Not Unix). Le système GNU a été pensé dans les années 80 comme étant une alternative Libre au système (gratuit) mais propriétaire Unix. Dans les années 80, à la préhistoire informatique, les systèmes d'ordinateurs n'avaient pour ainsi dire pas d'interface graphique (et encore moins de souris) : un noyau, un interpréteur de commande (shell) et quelques utilitaires suffisaient à faire un ordinateur fonctionnel. Ici le système Microsoft Disk Operating System fonctionnant avec les fichier : msdos.sys et io.sys (l'équivalent du noyau), config.sys et autoexec.bat, à partir de là l'interpréteur de commande (ou shell) : COMMAND.COM s'exécute et affiche l'image précédente. -
