Welcome! ======== This document contains information about the X11 for Mac OS X that you should read before you install this product. You will learn about getting started, supported computer systems, hardware requirements, software features, and known issues. X11 for Mac OS X is an implementation of the X Window System that makes it possible to run X11-based applications in Mac OS X. Based on the open source XFree86 project -- the most common implementation of X11 -- X11 for Mac OS X is compatible, fast, and fully integrated with Mac OS X. It includes the full X11R6.6 technology including an X11 window server, Quartz window manager, libraries, and basic utilities such as xterm. For more information about X11 for Mac OS X, visit the Apple Mac OS X website page for X11 at <www.apple.com/macosx/x11/> Getting Started =============== X11 for Mac OS X is distributed as part of the Mac OS system install. Simply select the optional X11 package when installing. Note that if you want to compile applications for use with X11, you will also need to download the X11 SDK package. After installing, you can activate the software by launching /Applications/Utilities/X11.app The application opens an initial xterm window with the PATH and DISPLAY variables set to the appropriate values. You can open additional windows from the "Applications" menu of X11.app. System Requirements =================== Your computer must have: - at least 256 MB of RAM - a built-in display or a display connected to an Apple-supplied video card - at least 200 MB of hard disk space available Features ======== Key features of the X11 for Mac OS X include: - direct and indirect native OpenGL support Direct rendering has exactly the same performance as the native Mac OS X OpenGL framework. Indirect rendering also uses the native GL implementation, but incurs the penalty of marshalling, transmitting and unmarshalling all GL primitives. - improved performance of X11 server operations through direct use of Quartz services - hardware-accelerated fill, copy (scroll) and compositing operations - more efficient dirty-region accounting - better support for shaped windows - minimized intermediate copies when resizing windows - new X11.app front end, including a fully-functional "Windows" menu - new "quartz-wm" window manager - provides a native Mac OS X look and feel for window decorations - uses the Mac OS X Dock for minimization and window placement - /usr/bin/open-x11 shell script available to launch X apps from Terminal. - ability to cut and paste between X11 and native applications using PRIMARY and PASTEBOARD selections. - Native fonts are available to Xft applications. - supports multi-button mice and scroll-wheel events - now handles display changes correctly Known Issues ============ For the list of known issues and any recent changes, please visit: http://developer.apple.com/qa/qa2001/qa1232.html Feedback ======== Bug reports and feature requests related to X11 for Mac OS X can and should be filed at developer.apple.com/bugreporter.
