It is + based on the XFree86 4.4RC2 RELNOTES document published by The + XFree86[tm] Project, Inc. There are significant updates and dif- + ferences in the X.Org release as noted below. + +1. Introduction to the X11R6.9/X11R7.0 Release + +This release constitutes the first major version release of the X Window Sys- +tem in over a decade. The main reasons for the major version bump from 6 to +7 is that we have moved from what has traditionally been a source codebase +comprised of many different components brought together into a single mono- +lithic tree to a source codebase where each of those same components found in +the monolithic tree are now split into logical modules that can be developed, +built and maintained separately, but still fit together coherently into the +larger project. At the same time, we have moved away from the imake build +system to an autotools build system. By making these changes we have opened +the source code up to a new generation of developers that can continue to +build upon the long tradition of the X Window System. + +The reason for having simultaneous releases for both the monolithic and modu- +lar trees is to allow for a transition period as developers, builders and +vendors incorporate the significant changes to how the tree is built and +developed into their products and to allow time for additional platforms to +be supported the modular tree. This initial modular release has support for +Linux and Solaris. During the transition period, we expect both the mono- +lithic and modular trees to coexist. For the monolithic tree, we expect that +there will be maintenance releases in the X11R6.8.x and X11R6.9.x series as +needed. However, the main development effort will move over to the new modu- +lar tree. + +The X11R7.0 release is the first in the modular series. One of the advan- +tages of the modular tree is that it allows for more rapid and independent +updates of module components, so full maintenance releases will no longer be +required for simple bug fixes. Rather, each module component maintainer can +prepare new releases as needed. These module component releases will then be +periodically "rolled up" into official X.Org Foundation releases. The next +official release will be X11R7.1 and is expected in mid 2006. + +For more information on the modularization effort see the Modularization Pro- +posal <URL:http://wiki.x.org/wiki/ModularizationProposal>, and for help with +how to build and develop in the new modular tree see Modular Developer's +Guide <URL:http://wiki.x.org/wiki/ModularDevelopersGuide>. + +We encourage you to submit bug fixes and enhancements to freedesktop.org's +bug tracking system <URL:https://bugs.freedesktop.org/> using the xorg prod- +uct, and to discuss them on <xorg@lists.freedesktop.org>. + +The release numbering is based on the original MIT X numbering system. X11 +refers to the version of the network protocol that the X Window system is +based on: Version 11 was first released in 1988 and has been stable for 17 +years, with only upward compatible additions to the core X protocol, a record +of stability envied in computing. Formal releases of X started with X ver- +sion 9 from MIT; the first commercial X products were based on X version 10. +The MIT X Consortium and its successors, the X Consortium, the Open Group X +Project Team, and the X.Org Group released versions X11R3 through X11R6.6, +before the founding of the X.Org Foundation in early 2004. + +The next section describes what is new in the latest version (6.9/7.0) com- +pared with the previous full release (6.8). The other sections below +describe some of the new features and changes between 3.3.x and 4.0. There +are lots of new features, and we definitely don't have enough space to cover +them all here. + +2. Summary of new features in X11R6.9 and X11R7.0 + +This is a sampling of the new features in X11R6.9/X11R7.0. A more complete +list of changes can be found in the ChangeLog file that is part of the X +source tree. + + o EXA support included + + EXA is a new accleration architecture to replace XAA, the current archi- + tecture. It is largely based upon KAA in KDrive, and is far more effi- + cient at accelerating typical workloads on modern hardware, particularly + involving the RENDER extension. + + o FreeType was updated to version 2.1.9. But installing FreeType from X + distributions would often or usually result in the replacement or use of + "stale" versions of FreeType. On Linux, FreeBSD, Solaris 10, and SCO5, + therefore, X11R6.9 will by default use the version of FreeType2 that is + installed on the system. If your system doesn't come with an installed + FreeType2 and you wish to use the version supplied with this distribu- + tion, please add: + + #define HasFreetype2 NO + + to config/cf/host.def. + + o Updated Mesa and DRI from upstream sources + + o More OpenGL extensions + + o Support for Radeon r3xx/r4xx and PCI-Express chips + + o Support for mixed 32-bit and 64-bit clients on 64-bit machines. + + o Individual extensions may be enabled or disabled on the command line + using the -extension flag + + o Improved chipset probing for IA64 + + o SecureRPC enabled on Linux by default + + o Updated XRX support + + o Fixes to rootless mode for Cygwin and Darwin ports + + o Numerous K&R-to-ANSI C conversions + + o Many Darwin fixes + + o Updated XvMC support, enabling generic loading of hardware-specific + drivers + + o Added wsfb video driver for OpenBSD and NetBSD framebuffer consoles + + o Numerous ATI driver updates from the GATOS project, including TV input + support + + o Improved ProPolice support + + o Improved module loader support for Alpha chips + + o Added mingw port for native Win32 builds + + o Updated PCI scanning + + o Experimental DRI support for Radeon 9500 and above + + o Updated xterm to #207 from Thomas Dickey's xterm project + <URL:http://dickey.his.com/xterm/xterm.html> + + o Added evdev input driver for generic input handling on Linux + + o Switched to libdl-based module loader + + o MMX blending routines for the Render extension + + o Initial support for running the Xorg server without root privileges + + o Add DragonFly BSD support + + o SGI Altix support + + o Support for FreeBSD/powerpc + + o Enhanced software Render core + + o Support for more than 12 buttons in the generic mouse driver + + o Better support for DRI on 64-bit platforms + + o Solaris support updates: + + o enhanced mouse driver + + o agpgart support + + o experimental AMD64 support + + o kbd support + + o /dev/audio keyboard bell option + + o Output-only windows + + o Non-rectangular mergedfb desktops + + o Update bundled fontconfig to 2.3.2 + + o Added gradient, solid fill, and convolution filter operations to Render + + o Support for XGI chipsets in SiS video driver + + o Xft updated to 2.1.7 + + o Include stack backtraces in logfiles when server crashes on glibc and + Solaris systems + + o Multiseat support + + o xload made compatible with 64-bit kernels on Solaris + + o Bundled Mesa upgraded to 6.4.1 + + o CAN-2005-2495 security fixes + + o Shared libraries now built for libXau and libXdmcp + + o GNU/kFreeBSD support + +2.1 Updated keyboard mappings + +The requirement for XKB data can, in the modular tree, be satisfied either by +the traditional data set (the 'xkbdata' module), or by the dataset from the +xkeyboard-config project (the 'xkbdesc' module). xkbdesc has numerous +improvements relative to xkbdata: layouts have been cleaned up for consis- +tency and universal multi-layout support, some new layouts have added, and +some layouts have changed names to be more straightforward and ISO compliant. +Some setups will need adjustments in order to use xkbdesc. + +2.2 New loader mechanism + +The loader now uses the standard libdl-based loader, instead of implementing +its own ELF loading and parsing mechanism. This extends loadable server sup- +port to many platforms where it was not previously possible, such as MIPS, +Motorola 68000, HP PA/RISC, et al. The core loader itself has also been sig- +nificantly optimised. + +2.3 Video driver enhancements + + o SiS driver updates include + + o Support for EXA acceleration + + o Support for non-rectangular MergedFB, including RandR + + o Support for XGI chipsets + + o New sisusb driver for USB-attached video + + o ATI driver updates + + o Mach64 TV out support + + o Rage 128 driver updates + + o Added dualhead support + + o Radeon driver updates + + o Support for non-rectangular MergedFB + + o Support for EXA acceleration + + o Full 3D support for r3xx/r4xx series, and PCI-Express + + o Support for RN50/ES1000 chips + + o VIVO support merged from the GATOS project + + o Hostdata blit support for Xv videos and RENDER images + + o BIOS hotkey support + + o Tiled framebuffer support + + o MGA driver updates + + o New BIOS parsing + + o i810 driver updates + + o i915GM, i945G and E7221 support + + o Linux power management support (ACPI) + + o BIOS hotkey support + + o ShadowFB support + + o Improved DDC support + + o SunFFB driver updates + + o XAA acceleration + + o Savage driver updates + + o Support for PCI Savages + + o Added dualhead and DRI support + + o Newport driver updates + + o XAA acceleration + + o VIA driver updates + + o Unichrome Pro support + + o DRI support + + o NV driver updates + + o DPMS support for GeForce4 and greater laptops + + o VMWare driver updates + + o RandR support + +3.

Overview of X11R6.9 and X11R7.0 + +On most platforms, X11R6.9/X11R7.0 has a single X server binary called Xorg. +This binary can either have one or more video and input drivers linked in +statically, or more usually, dynamically, and in that manner load the video +drivers, input drivers, and other modules that are needed. + +X11R6.9 has X server support for most UNIX and UNIX-like operating systems +on Intel/x86 platforms, plus support for Linux and some BSD OSs on Alpha, +PowerPC, IA-64, AMD64, Sparc, and Mips platforms, and for Darwin on PowerPC. +X11R7.0 has X server currently has support for Linux and Solaris, and is +expected to have other platform support in X11R7.1. + +4.1 Loader and Modules + +The X server has a built-in run-time loader, which can load normal object +files and libraries in most of the commonly used formats. The loader does +not rely on an operating system's native dynamic loader support and it works +on platforms that do not provide this feature. This allows for the modules +to be operating system independent (although not, of course, CPU architecture +independent) which means that a module compiled on Linux/x86 can be loaded by +an X server running on Solaris/x86, or FreeBSD, or even OS/2. + +A main benefit of this, is that when modules are updated, they do not need to +be recompiled for every different operating system. The loader in version +6.9/7.0 has support for Intel (x86), Alpha and PowerPC platforms. It also +has preliminary support for Sparc platforms. + +The X server makes use of modules for video drivers, X server extensions, +font rasterisers, input device drivers, framebuffer layers (like mfb, cfb, +etc), and internal components used by some drivers (like XAA), + +The module interfaces (both API and ABI) used in this release are subject to +change without notice. While we will attempt to provide backward compatibil- +ity for the module interfaces as of the 4.0 release (meaning that 4.0 modules +will work with future core X server binaries), we cannot guarantee this. +Compatibility in the other direction is explicitly not guaranteed because new +modules may rely on interfaces added in new releases. + +Note about module security + + The X server runs with root privileges, i.e., the X server loadable + modules also run with these privileges. For this reason we recom- + mend that all users be careful to only use loadable modules from + reliable sources, otherwise the introduction of viruses and con- + taminated code can occur and wreak havoc on your system. We hope + to have a mechanism for signing/verifying the modules that we pro- + vide available in a future release. + +4.2 Configuration File + +The X server uses a configuration file as the primary mechanism for providing +configuration and run-time parameters. The configuration file format is +described in detail in the xorg.conf(5) manual page. + +This release comes with a graphical configuration tool called "xorgcfg", +which also has a text mode interface and can be used to create an initial +configuration file. It can also be used to customise existing configurations. + +Next in the order of configuration preferences is to use the Xorg server's +ability to create a starting configuration file. Run as root: + + Xorg -configure + + and follow the instructions. + +Finally, if all else fails, the trusty old standby text-based tool "xorgcon- +fig" can also be used for generating X server config files. + +At least one, and hopefully, all of these configuration options will give you +a reasonable starting point for a suitable configuration file. With the +automatic mechanism you might even find that you don't need one! + +If you do need to customize the configuration file, see the xorg.conf manual +page. You can also check the driver-specific manual pages and the related +documentation (found at tables below (section , page ) also. + +4.3 Command Line Options + +Command line options can be used to override some default parameters and +parameters provided in the configuration file. These command line options +are described in the Xorg(1) manual page. + +4.4 XAA + +The XFree86 Acceleration Architecture (XAA) was completely rewritten from +scratch for XFree86 4.x and is used in X11R6.9/X11R7.0. Most drivers imple- +ment acceleration by making use of the XAA module. The Xorg server will +accept modules built either for XFree86 4.4 servers or its own. + +4.5 Multi-head + +Some multi-head configurations are supported in X11R6.9/X11R7.0, primarily +with multiple PCI/AGP cards. + +One of the main problems is with drivers not sufficiently initialising cards +that were not initialised at boot time. This has been improved somewhat with +the INT10 support that is used by most drivers (which allows secondary card +to be "soft-booted", but in some cases there are other issues that still need +to be resolved. Some combinations can be made to work better by changing +which card is the primary card (either by using a different PCI slot, or by +changing the system BIOS's preference for the primary card). + +4.6 Xinerama + +Xinerama is an X server extension that allows multiple physical screens to +behave as a single screen. With traditional multi-head in X11, windows can- +not span or cross physical screens. Xinerama removes this limitation. Xin- +erama does, however, require that the physical screens all have the same root +depth, so it isn't possible, for example, to use an 8-bit screen together +with a 16-bit screen in Xinerama mode. + +Xinerama is not enabled by default, and can be enabled with the +xinerama +command line option for the X server. + +Xinerama was included with X11R6.4. The version included in X11R6.9/X11R7.0 +was completely rewritten for improved performance and correctness. + +Known problems: + + o Most window managers are not Xinerama-aware, and so some operations like + window placement and resizing might not behave in an ideal way. This is + an issue that needs to be dealt with in the individual window managers, + and isn't specifically an X server problem. + +4.7 DGA version 2 + +DGA 2.0 is included in 6.9/7.0. Documentation for the client libraries can +be found in the XDGA(3) man page. A good degree of backwards compatibility +with version 1.0 is provided. + +4.8 DDC + +The VESA Display Data Channel (DDC[tm]) standard allows the monitor to tell +the video card (or on some cases the computer directly) about itself; partic- +ularly the supported screen resolutions and refresh rates. + +Partial or complete DDC support is available in most of the video drivers. +DDC is enabled by default, but can be disabled with a "Device" section entry: +Option "NoDDC". We have support for DDC versions 1 and 2; these can be dis- +abled independently with Option "NoDDC1" and Option "NoDDC2". + +At startup the server prints out DDC information from the display, and can +use this information to set the default monitor parameters, or to warn about +monitor sync limits if those provided in the configuration file don't match +those that are detected. + +4.8.1 Changed behavior caused by DDC. + +Several drivers uses DDC information to set the screen size and pitch. This +can be overridden by explicitly resetting it to the and non-DDC default value +75 with the -dpi 75 command line option for the X server, or by specifying +appropriate screen dimensions with the "DisplaySize" keyword in the "Monitor" +section of the config file. + +4.9 GLX and the Direct Rendering Infrastructure (DRI) + +Direct rendered OpenGL support is provided for several hardware platforms by +the Direct Rendering Infrastructure (DRI). Further information about DRI can +be found at the DRI Project's web site <URL:http://dri.sf.net/>. The 3D core +rendering component is provided by Mesa <URL:http://www.mesa3d.org>. + +4.10 XVideo Extension (Xv) + +The XVideo extension is supported in X11R6.7.x. An XvQueryPortAttributes +function has been added as well as support for XvImages. XvImages are XIm- +ages in alternate color spaces such as YUV and can be passed to the server +through shared memory segments. This allows clients to display YUV data with +high quality hardware scaling and filtering. + +4.11 X Rendering Extension (Render) + +The X Rendering extension provides a 2D rendering model that more closely +matches application demands and hardware capabilities. It provides a render- +ing model derived from Plan 9 based on Porter/Duff image composition rather +than binary raster operations. + +Using simple compositing operators provided by most hardware, Render can draw +anti-aliased text and geometric objects as well as perform translucent image +overlays and other image operations not possible with the core X rendering +system. + +Unlike the core protocol, Render provides no font support for applications, +rather it allows applications to upload glyphs for display on the screen. +This allows the client greater control over text rendering and complete +access to the available font information while still providing hardware +acceleration. The Xft library provides font access for Render applications. + +4.11.1 The Xft Library + +On the client side, the Xft library provides access to fonts for applications +using the FreeType library, version 2. One important thing to note is that +Xft uses the vertical size of the monitor to compute accurate pixel sizes for +provided point sizes; if your monitor doesn't provide accurate information +via DDC, you may want to add that information to xorg.conf. + +To allow a graceful transition for applications moving from core text render- +ing to the Render extension, Xft can use either the core rendering requests +or the Render extension for text. See the section on FreeType support in Xft +for instructions on configuring X11R6.9/X11R7.0 to use an existing FreeType +installation. + +The Xft library uses configuration files, /etc/fonts/fonts.conf and +/etc/fonts/local.conf, which contains information about which directories +contain font files and also provides a sophisticated font aliasing mechanism. +Documentation for that file is included in the Xft(3) man page. + +4.11.2 Application Support For Anti-Aliased Text + +Only four applications have been modified in X11R6.9/X11R7.0 to work with the +Render extension and the Xft and FreeType libraries to provide anti-aliased +text: xterm, xditview, x11perf and xclock. Migration of other applications +may occur in future releases. + +By default, xterm uses core fonts through the standard core API. It has a +command line option and associated resource to direct it to use Xft instead: + + o -fa family / .VT100.faceName: family. Selects the font family to use. + +Xditview will use Xft instead of the core API by default. X11perf includes +tests to measure the performance of text rendered in three ways, anti- +aliased, anti-aliased with sub-pixel sampling and regular chunky text, but +through the Render extension, a path which is currently somewhat slower than +core text. + +Xclock uses the Render extension to draw the analog face and shares the -fa +option and faceName resources with xterm to select a font for the digital +mode. + +4.12 Other extensions + +The XFree86-Misc extension has not been fully ported to the new server archi- +tecture yet. This should be completed in a future release. + +The XFree86-VidModeExtension extension has been updated, and mostly ported to +the new server architecture. The area of mode validation needs further work, +and the extension should be used with care. This extension has support for +changing the gamma setting at run-time, for modes where this is possible. +The xgamma utility makes use of this feature. Compatibility with the 3.3.x +version of the extension is provided. The missing parts of this extension +and some new features should be completed in a future release. + +4.13 xedit + +Xedit has several new features, including: + + o An embedded lisp interpreter that allows easier extension of the editor. + + o Several new syntax highlight modes, and indentation rules for C and + Lisp. + + o Flexible search/replace interface that allows regex matches. + + o Please refer to xedit(1) for more details. + + o XPrint support. + +4.14 Font support + +Details about the font support in X11R6.9.x/X11R7.0.x can be found in the +README.fonts document. + +4.15 TrueType support + +X11R6.7 came with two TrueType backends. The functionality from the `X-True- +Type' backend has been integrated into the `FreeType' backend which is +designed to transparently support all of the functionality from the `X-True- +Type' backend with the exception of the font encoding libraries; the +`FreeType' backend uses only the fontenc-based encoding system . + +4.16 CID font support + +Support for CID-keyed fonts is included in X11R6.9/X11R7.0 The CID-keyed font +format was designed by Adobe Systems <URL:http://www.adobe.com> for fonts +with large character sets. The CID-keyed font support in X11R6.9/X11R7.0 was +donated by SGI <URL:http://www.sgi.com>. See the LICENSE document for a copy +of the CID Font Code Public License. + +4.17 Internationalisation of the scalable font backends + +X11R6.9/X11R7.0 has a ``fontenc'' layer to allow the scalable font backends +to use a common method of font re-encoding. This re-encoding makes it possi- +ble to uses fonts in encodings other than their their native encoding. This +layer is used by the Type1 and FreeType backends. + +4.18 Large font optimisation + +The glyph metrics array, which all the X clients using a particular font have +access to, is placed in shared memory, so as to reduce redundant memory con- +sumption. For non-local clients, the glyph metrics array is transmitted in a +compressed format. + +4.19 Unicode/ISO 10646 support + +What is included in X11R6.9/X11R7.0 + + o All ``-misc-fixed-*'' BDF fonts are now available in the ISO10646-1 + encoding and cover at least the 614 characters found in ISO + 8859-{1-5,7-10,14,15}, CP1252, and MES-1. The non-bold fonts also cover + all Windows Glyph List 4 (WGL4) characters, including those found in all + 8-bit MS-DOS/Windows code pages. The 8-bit variants of the ``-misc- + fixed-*'' BDF fonts (ISO8859-1, ISO8859-2, KOI8-R, etc.) have all been + automatically generated from the new ISO10646-1 master fonts. + + o Some ``-misc-fixed-*'' BDF ISO10646-1 fonts now cover a comprehensive + Unicode repertoire of over 3000 characters including all Latin, Greek, + Cyrillic, Armenian, Gregorian, Hebrew, IPA, and APL characters, plus + numerous scientific, typographic, technical, and backwards-compatibility + symbols. Some of these fonts also cover Arabic, Ethiopian, Thai, + Han/Kanji, Hangul, full ISO 8859, and more. For the 6x13 font there is + now a 12x13ja Kanji extension and for the 9x18 font there is a 18x18ja + Kanji/Han/Hangul extension, which covers all ISO-2022-JP-2 (RFC 1554) + characters. The 9x18 font can also be used to implement simple combining + characters by accent overstriking. For more information, read Markus + Kuhn's UTF-8 and Unicode FAQ <URL:http://www.cl.cam.ac.uk/~mgk25/uni- + code.html>. + + o Mark Leisher's ClearlyU proportional font (similar to Computer Modern). + + o ISO 10646/Unicode UTF-8 Level 1 support added to xterm (enabled with the + -u8 option). + + o The Freetype backend (the "freetype" module) supports Unicode-encoded + fonts. + +4.20 Xlib Compose file support and extensions + +A more flexible Compose file processing system was added to Xlib in +X11R6.9/X11R7.0. The compose file is searched for in the following order: + + 1. If the environment variable $XCOMPOSEFILE is set, its value is used as + the name of the Compose file. + + 2. If the user's home directory has a file named ".XCompose", it is used + as the Compose file. + + 3. The old method is used, and the compose file is "<xlocaledir>/<locale- + name>/Compose". + +Compose files can now use an "include" instruction. This allows local modi- +fications to be made to existing compose files without including all of the +content directly. For example, the system's iso8859-1 compose file can be +included with a line like this: + + include "/usr/X11R6/lib/X11/locale/iso8859-1/Compose" + +There are two substitutions that can be made in the file name of the include +instruction. %H expands to the user's home directory (the $HOME environment +variable), and %L expands to the name of the locale specific Compose file +(i.e., "<xlocaledir>/<localename>/Compose"). + +For example, you can include in your compose file the default Compose file by +using: + + include "%L" + +and then rewrite only the few rules that you need to change. New compose +rules can be added, and previous ones replaced. + +Finally, it is no longer necessary to specify in the right part of a rule a +locale encoded string in addition to the keysym name. If the string is omit- +ted, Xlib figures it out from the keysym according to the current locale. +I.e., if a rule looks like: + + <dead_grave> <A> : "\300" Agrave + +the result of the composition is always the letter with the "\300" code. But +if the rule is: + + <dead_grave> <A> : Agrave + +the result depends on how Agrave is mapped in the current locale. + +4.21 Bitstream Vera fonts + +X11R6.9 includes the Bitstream Vera family of typefaces in TrueType format. +This family includes the ``Bitstream Vera Sans'', ``Bitstream Vera Sans +Mono'' and ``Bitstream Vera Serif'' in Roman and Bold varients as well as the +``Bitstream Vera Sans'' and ``Bitstream Vera Sans Mono'' in Oblique and Bold +Oblique. These fonts include all of the glyphs needed for ISO 8859 parts 1 +9 and 15. + +The license terms for the Vera fonts are inclued in the file COPYRIGHT.Vera>. + +4.22 Luxi fonts from Bigelow and Holmes + +The X distribution includes the ``Luxi'' family of Type 1 fonts and TrueType +fonts. This family consists of the fonts ``Luxi Serif'', ``Luxi Sans'' and +``Luxi Mono'' in Roman, oblique, bold and bold oblique variants. The True- +Type version have glyphs covering the basic ASCII Unicode range, the Latin 1 +range, as well as the Extended Latin range and some additional punctuation +characters. In particular, these fonts include all the glyphs needed for +ISO 8859 parts 1, 2, 3, 4, 9, 13 and 15, as well as all the glyphs in the +Adobe Standard encoding and the Windows 3.1 character set. + +The glyph coverage of the Type 1 versions is somewhat reduced, and only cov- +ers ISO 8859 parts 1, 2 and 15 as well as the Adobe Standard encoding. + +The Luxi fonts are original designs by Kris Holmes and Charles Bigelow from +Bigelow and Holmes Inc., who developed the Luxi typeface designs in Ikarus +digital format. URW++ Design and Development GmbH converted the Ikarus for- +mat fonts to TrueType and Type 1 font programs and implemented the grid-fit- +ting "hints" and kerning tables in the Luxi fonts. + +The license terms for the Luxi fonts are included in the file `COPYRIGHT.BH', +as well as in the License document. For further information, please contact +<design@bigelowandholmes.com> or <info@urwpp.de>, or consult the URW++ web +site <URL:http://www.urwpp.de>. + +5. Miscellaneous + +This section describes other items of note for the X11R6.9/X11R7.0 release. + +5.1 Legacy keyboard driver phase-out + +The legacy keyboard driver is no longer compiled into the X server by default +on certain platforms (including Linux). The newer kbd driver replaces the +older built-in driver. It is suggested that, if the X server says that it +cannot load the keyboard driver, then the xorg.conf file should be updated to +use the new kbd driver, which can be done by changing the Driver line in the +InputDevice section. For example, + + Section "InputDevice" + Identifier "Keyboard0" + Driver "kbd" + EndSection + +Note that the driver name is case-sensitive. + +5.2 Socket directory ownership and permissions + +The socket directories created in /tmp are now required to be owned by root +and have their sticky-bit set. If the permissions are not set correctly, the +component using this directory will print an error message and fail to start. +Common socket directories that are known to be affected include: + + /tmp/.font-unix + /tmp/.ICE-unix + /tmp/.X11-unix + +These directories are used by the font server, xfs, applications using the +Inter-Client Exchange protocol (ICE) and the X server, respectively. + +There are several solutions to the problem of when to create these directo- +ries. They could be created at install time by the system's installer if the +/tmp dir is persistent. They could be created at boot time by the system's +boot scripts (e.g., the init.d scripts). Or, they could be created by PAM +modules at service startup or user login time. + +The solution chosen is platform dependent, and the system administrator +should be able to handle creating those directories on any systems that do +not have the correct ownership or permissions. + +5.3 Composite exposes extra visuals + +When the Composite extension is enabled via xorg.conf or the command line, a +new visual is created. This visual is different from the other visuals used +by X applications in that it includes an alpha component. It is used by the +compositing manager and other Composite aware applications. + +Most X applications ignore this visual since it is not useful to them; how- +ever some applications mistakenly try to use it, which will cause them to +fail. An environment variable, XLIB_SKIP_ARGB_VISUALS, was added to the X11 +library to hide this visual from applications that mistakenly try to use it. +If an application fails only when the Composite is enabled, try setting this +environment variable before starting the application. + +Since Composite is not enabled by default, it is not expected that this issue +will be visible to most users. + +6. Deprecated components and removal plans + +This section lists current plans for removal of obsolete or deprecated compo- +nents in the X.Org releases. As our releases are open source, users who con- +tinue to require these can find the source in previous releases and continue +to use these, but the X.Org Foundation and its volunteers have decided the +burden of continued maintenance and distribution in the core X11 releases +outweighs the benefits of doing so. In some cases, this is simply because no +one has volunteered to do continued maintenance, so if software is listed +here that you need, you can contact <xorg@lists.freedesktop.org> to volunteer +to take over maintainership, either inside or outside of the Xorg release +process. + + Display Postscript (DPS) + The DPS software is included and built by default (except as + noted in README.dps) in the X.Org X11R6.8 release series. The + software will be included, but not built unless specifically con- + figured by the builder, in the X.Org X11R6.9 release series. At + this time, X.Org does not plan to include any of the DPS software + in X11R7.0 or later releases. For more information, see xc/pro- + grams/Xserver/hw/xfree86/doc/README.dps in the X.Org source + release. + +7. Attributions/Acknowledgements/Credits + +This section lists the credits for the X11R6.9/X11R7.0 release.
