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. -

Troubleshooting Passwords
Troubleshooting Passwords The following procedures may be used to troubleshoot password problems: • Performing Password Recovery with an Existing Administrator, page 1 • Performing Password Recovery with No Existing Administrator, page 1 • Performing Password Recovery for the Linux Grapevine User Account, page 2 Performing Password Recovery with an Existing Administrator To perform password recovery for a user (administrator, installer or observer) where there exists at least one controller administrator (ROLE_ADMIN) user account, take the following steps: 1 Contact the existing administrator to set up a temporary password for the user that requires password recovery. Note The administrator can set up a temporary password by deleting the user's account and then recreating it with the lost password. The user can then log back into the controller to regain access and change the password once again to whatever he or she desires. 2 The user then needs to log into the controller with the temporary password and change the password. Note Passwords are changed in the controller GUI using the Change Password window. For information about changing passwords, see Chapter 4, Managing Users and Roles in the Cisco Application Policy Infrastructure Controller Enterprise Module Configuration Guide. Performing Password Recovery with No Existing Administrator The following procedure describes how to perform password recovery where there exists only one controller administrator (ROLE_ADMIN) user account and this account cannot be successfully logged into. Cisco Application Policy Infrastructure Controller Enterprise Module Troubleshooting Guide, Release 1.3.x 1 Troubleshooting Passwords Performing Password Recovery for the Linux Grapevine User Account Note We recommend that you create at least two administrator accounts for your deployment. -

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. -

The Strange Birth and Long Life of Unix - IEEE Spectrum Page 1 of 6
The Strange Birth and Long Life of Unix - IEEE Spectrum Page 1 of 6 COMPUTING / SOFTWARE FEATURE The Strange Birth and Long Life of Unix The classic operating system turns 40, and its progeny abound By WARREN TOOMEY / DECEMBER 2011 They say that when one door closes on you, another opens. People generally offer this bit of wisdom just to lend some solace after a misfortune. But sometimes it's actually true. It certainly was for Ken Thompson and the late Dennis Ritchie, two of the greats of 20th-century information technology, when they created the Unix operating system, now considered one of the most inspiring and influential pieces of software ever written. A door had slammed shut for Thompson and Ritchie in March of 1969, when their employer, the American Telephone & Telegraph Co., withdrew from a collaborative project with the Photo: Alcatel-Lucent Massachusetts Institute of KEY FIGURES: Ken Thompson [seated] types as Dennis Ritchie looks on in 1972, shortly Technology and General Electric after they and their Bell Labs colleagues invented Unix. to create an interactive time- sharing system called Multics, which stood for "Multiplexed Information and Computing Service." Time-sharing, a technique that lets multiple people use a single computer simultaneously, had been invented only a decade earlier. Multics was to combine time-sharing with other technological advances of the era, allowing users to phone a computer from remote terminals and then read e -mail, edit documents, run calculations, and so forth. It was to be a great leap forward from the way computers were mostly being used, with people tediously preparing and submitting batch jobs on punch cards to be run one by one.
