Release Notes for X11R6.8.2 the X.Orgfoundation the Xfree86 Project, Inc
Release Notes for X11R6.8.2 The X.OrgFoundation The XFree86 Project, Inc. 9February 2005 Abstract These release notes contains information about features and their status in the X.Org Foundation X11R6.8.2 release. It is based on the XFree86 4.4RC2 RELNOTES docu- ment published by The XFree86™ Project, Inc. Thereare significant updates and dif- ferences in the X.Orgrelease as noted below. 1. Introduction to the X11R6.8.2 Release The release numbering is based on the original MIT X numbering system. X11refers to the ver- sion of the network protocol that the X Window system is based on: Version 11was first released in 1988 and has been stable for 15 years, with only upwardcompatible additions to the coreX protocol, a recordofstability envied in computing. Formal releases of X started with X version 9 from MIT;the first commercial X products werebased on X version 10. The MIT X Consortium and its successors, the X Consortium, the Open Group X Project Team, and the X.OrgGroup released versions X11R3 through X11R6.6, beforethe founding of the X.OrgFoundation. Therewill be futuremaintenance releases in the X11R6.8.x series. However,efforts arewell underway to split the X distribution into its modular components to allow for easier maintenance and independent updates. We expect a transitional period while both X11R6.8 releases arebeing fielded and the modular release completed and deployed while both will be available as different consumers of X technology have different constraints on deployment. Wehave not yet decided how the modular X releases will be numbered. We encourage you to submit bug fixes and enhancements to bugzilla.freedesktop.orgusing the xorgproduct, and discussions on this server take place on <[email protected]>. -
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. -

How To: X11 Forwarding
written by Nate Book, `14 on 12/08/2011 updated 12/09/2011 How To: X11 Forwarding or, how to get Matlab through SSH Introduction SSH allows you to remotely access the cycle computers to test code for C (gcc, make), Prolog (pl), and Scheme (racket). All of these are accessible via the command-line. If you’re on Windows, you are familiar with something simple like PuTTY. On Linux or Mac, a command like ssh name@host brings it up for you. It’s command-line only and you’re stuck wondering, is there something better? Is there some way to access the familiar Dr. Racket interface as opposed to just racket? Is there a way to get the graphical Matlab environment (typing matlab just gives an error about a missing display— this is correct since it doesn’t know about your display. You might as well ssh from a non-graphical OS for all it cares)? Yes! The trick is X11 Forwarding. Linux and X11 X11 is the 11th version of the X Windows Server (not related to Windows in any way), a protocol allowing window managers to display GUIs on many Linux distributions such as Fedora or Ubuntu. X11 is a server in that applications “connect” to it and send it abstracted GUI information. It also allows remote computers to do the same through, for example, SSH. To actually do this on any OS you need two things, OpenSSH and X.Org. The following sections detail this for common operating systems. Linux/Unix-based This is astoundingly easy to do on any distribution that comes with X Windows. -
Aligning Intent and Behavior in Software Systems: How Programs Communicate & Their Distribution and Organization
© 2020 William B. Dietz ALIGNING INTENT AND BEHAVIOR IN SOFTWARE SYSTEMS: HOW PROGRAMS COMMUNICATE & THEIR DISTRIBUTION AND ORGANIZATION BY WILLIAM B. DIETZ DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Computer Science in the Graduate College of the University of Illinois at Urbana-Champaign, 2020 Urbana, Illinois Doctoral Committee: Professor Vikram Adve, Chair Professor John Regehr, University of Utah Professor Tao Xie Assistant Professor Sasa Misailovic ABSTRACT Managing the overwhelming complexity of software is a fundamental challenge because complex- ity is the root cause of problems regarding software performance, size, and security. Complexity is what makes software hard to understand, and our ability to understand software in whole or in part is essential to being able to address these problems effectively. Attacking this overwhelming complexity is the fundamental challenge I seek to address by simplifying how we write, organize and think about programs. Within this dissertation I present a system of tools and a set of solutions for improving the nature of software by focusing on programmer’s desired outcome, i.e. their intent. At the program level, the conventional focus, it is impossible to identify complexity that, at the system level, is unnecessary. This “accidental complexity” includes everything from unused features to independent implementations of common algorithmic tasks. Software techniques driving innovation simultaneously increase the distance between what is intended by humans – developers, designers, and especially the users – and what the executing code does in practice. By preserving the declarative intent of the programmer, which is lost in the traditional process of compiling and linking and building software, it is easier to abstract away unnecessary details. -
The Linux Gamers' HOWTO
The Linux Gamers’ HOWTO Peter Jay Salzman Frédéric Delanoy Copyright © 2001, 2002 Peter Jay Salzman Copyright © 2003, 2004 Peter Jay SalzmanFrédéric Delanoy 2004-11-13 v.1.0.6 Abstract The same questions get asked repeatedly on Linux related mailing lists and news groups. Many of them arise because people don’t know as much as they should about how things "work" on Linux, at least, as far as games go. Gaming can be a tough pursuit; it requires knowledge from an incredibly vast range of topics from compilers to libraries to system administration to networking to XFree86 administration ... you get the picture. Every aspect of your computer plays a role in gaming. It’s a demanding topic, but this fact is shadowed by the primary goal of gaming: to have fun and blow off some steam. This document is a stepping stone to get the most common problems resolved and to give people the knowledge to begin thinking intelligently about what is going on with their games. Just as with anything else on Linux, you need to know a little more about what’s going on behind the scenes with your system to be able to keep your games healthy or to diagnose and fix them when they’re not. 1. Administra If you have ideas, corrections or questions relating to this HOWTO, please email me. By receiving feedback on this howto (even if I don’t have the time to answer), you make me feel like I’m doing something useful. In turn, it motivates me to write more and add to this document. -

Xfree86® on Darwin and Mac OS X Torrey T
XFree86® on Darwin and Mac OS X Torrey T. Lyons 15 December 2003 1. Introduction XFree86, a freely redistributable open-source implementation of the X Window System, has been ported to Darwin and Mac OS X. This document is a collection of information for anyone running XFree86 on Apple’s next generation operating system. Most of the current work on XFree86 for Darwin and Mac OS Xiscentered around the XonX project at SourceForge. If you areinterested in up-to-date status, want to report a bug, or are interested in working on XFree86 for Darwin, stop by the XonX project. 2. Hardware Supportand Configuration The X window server for Darwin and Mac OS Xprovided by the XFree86 Project, Inc. is called XDarwin. XDarwin can run in three different modes. On Mac OS X, XDarwin runs in parallel with Aqua in full screen or rootless modes. These modes arecalled Quartz modes, named after the Quartz 2D compositing engine used by Aqua. XDarwin can also be run from the Darwin con- sole in IOKit mode. In full screen Quartz mode, when the X Window System is active, it takes over the entirescreen. Youcan switch back to the Mac OS Xdesktop by holding down Command-Option-A. This key combination can be changed in the user preferences. From the Mac OS Xdesktop, click on the XDarwin icon in the Dock to switch back to the X window system. (You can change this behavior in the user preferences so that you must click the XDarwin icon in the floating switch window instead.) In rootless mode, the X window system and Aqua shareyour display. -
Dotex — Integrating TEX Into the X Window System
Dotex — Integrating TEX into the X Window System Anthony J. Starks Merck Research Laboratories Computer Resources, RY86-200 126 Lincoln Avenue Rahway, NJ 07065 U.S.A. Phone: (908) 594 – 7288 FAX: (908) 594 – 1455 Internet: [email protected] Abstract Dotex is a system to integrate TEX tools and automate the format, edit, preview, and print cycle in the X Window System. Dotex uses a single X Window client, xtmenu, to provide a simple push-button interface to the TEX formatter, text editor, and dvi previewer. Other functions such as spell-checking are easily added. Dotex’s function is to integrate, not change existing tools, providing a highly interactive “point and shoot” interface to traditional batch-oriented programs. Dotex’s chief advantage is allowing the user to rapidly visualize changes in the manuscript, thus facilitating such things as prototyping different typographic effects. Introduction more importantly, the execution of an arbitrary program. TEX is an interactive, terminal based program, but today’s computing environment is increasingly xdvi. xdvi is a typical dvi previewer that has window- and mouse-based. Dotex provides a “point several attractive features: and click” wrapper around TEX and other tools in • It uses the same font bitmaps as the printer, so the X Window System (Gettys et al, 1990). that a special set of font bitmaps is not needed Dotex was built out of the frustration of just for the previewer. constantly running an editor and the TEX formatter • xdvi has a rich, unobtrusive interaction model during the document preparation cycle. The first for moving around within the dvi file, including step was to use the built-in history and line editing jumping to a particular page and zooming to functions of the shell command interpreter, but different magnifications. -
