Introduction to the X11R7.7 Release

   This release is the eighth modular release of the X Window
   System(TM). The next full release will be X11R7.8 and is
   expected in 2013.

   Unlike X11R1 through X11R6.9, X11R7.x releases are not built
   from one monolithic source tree, but many individual modules.
   These modules are distributed as individual source code
   releases, and each one is released when it is ready, instead of
   only when the overall window system is ready for release. The
   X11R7.x releases are made by "rolling up" the individual module
   releases into a collection that is often affectionately called
   the "katamari" by the developers.

   The X11R7.7 release does not include all of the software
   formerly included in the previous X Window System releases. It
   is designed to be a reasonable baseline from which to start
   when building the window system for the first time for a new
   installation, distribution, or package set. It does not provide
   a full desktop environment, expecting a more feature rich set
   of applications to be installed from one of the several
   excellent desktop environments available for the X Window
   System. The X.Org developers continue to maintain and produce
   new releases of much of the software that was formerly in the
   main window system releases but is no longer included in the
   katamari releases, including many of the Athena Widgets desktop
   applications that were provided as samples in previous window
   system versions.

   Once their window system build is established, most builders
   watch for announcements of individual module updates on the
   xorg-announce mailing list and update to those as needed. The
   X.Org Foundation currently releases the X Window System
   katamari releases approximately once a year, but many modules,
   especially the X servers and drivers, are updated more
   frequently between those releases.

   For help with how to build and develop in the modular tree see
   the Modular Developer's Guide in the X.Org wiki.

   We encourage you to report bugs using freedesktop.org's bug
   tracking system using the xorg product, and to submit bug fixes
   and enhancements to <xorg-devel@lists.x.org>. More details on
   patch submission and review process are available on the
   SubmittingPatches page of the X.Org wiki.

   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 nearly 25 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 version 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. Since the
   founding of the X.Org Foundation in early 2004, many further
   releases have been issued, from X11R6.7 to the current 7.7.

   The next section describes what is new in the latest full
   release (7.7) compared with the previous full release (7.6).

Summary of new features in X11R7.7

   This is a sampling of the new features in X11R7.7. A more
   complete list of changes can be found in the ChangeLog files
   that are part of the source of each X module.

     * Multi-touch events are now supported for touchpads and
       touchscreens which can report position information on more
       than one finger providing input at the same time, such as
       found on many tablets and recent laptops. These are exposed
       by Xorg server 1.12 and later via the Xinput extension
       version 2.2.
     * Additional Xinput extension features were introduced in
       version 2.1, as supported in Xorg server 1.11, including
       allowing clients to track raw events from input devices,
       additional detail in scrolling events so that clients may
       perform smoother scrolling, and additional constants in the
       Xlib-based libXi API.
     * More progress has been made on the X.Org Documentation
       modernization - the rest of the library and protocol
       specifications have been converted to DocBook XML from the
       variety of formats they were previously in, and support for
       cross-linking between documents hase been added. On most
       systems these documents will be installed under
       /usr/share/doc/. They are also posted on the X.Org website
       at http://www.x.org/releases/X11R7.7/.
     * Fence objects are now available in Version 3.1 of the
       Synchronization ("Sync") extension. These allow clients to
       create a object that is either in "triggered" or
       "not-triggered" state, and to perform actions when the
       object becomes triggered. When a client requests a fence be
       triggered, the X server will first complete all rendering
       from previous requests that affects resources owned by the
       fence's screen before changing the state, so that clients
       may synchronize with such rendering. Support for these has
       been added to both the libxcb-sync and libXext API's.
     * Pointer barriers were added by X Fixes extension Version
       5.0. Compositing managers and desktop environments may have
       UI elements in particular screen locations such that for a
       single-headed display they correspond to easy targets, for
       example, the top left corner. For a multi-headed
       environment these corners should still be semi-impermeable.
       Pointer barriers allow the application to define additional
       constraint on cursor motion so that these areas behave as
       expected even in the face of multiple displays.
     * The XCB libraries have begun adding support for the GLX and
       XKB extensions. This work is not yet complete in this
       release, and not all of the functionality available through
       these extensions is accessibile via the XCB APIs. Some of
       this effort was funded by past Google Summer of Code
       projects.
     * Video and input driver enhancements. Please see the
       ChangeLog files for individual drivers; there are far too
       many updates to list here.
     * ... and the usual assortment of correctness and crash
       fixes.

Overview of X11R7.7

   On most platforms, X11R7.7 has a single hardware-driving X
   server binary called Xorg. This binary can dynamically load the
   video drivers, input drivers, and other modules that are
   needed. Xorg has currently has support for Linux, Solaris, and
   some BSD OSs on Alpha, PowerPC, IA-64, AMD64, Intel x86, Sparc,
   and MIPS platforms.

   Additional specialized X server binaries may be found depending
   on the platform and build configuration, including:

   Xdmx
          is a proxy X server that uses one or more other X
          servers as its display devices. It provides multi-head X
          functionality for displays that might be located on
          different machines.

   Xnest
          is a nested X server, that operates as both an X client
          and X server. Xnest is a client of the real server which
          manages windows and graphics requests on its behalf.
          Xnest is a server to its own clients, and manages
          windows and graphics requests on their behalf. To these
          clients, it appears to be a conventional server.

   Xephyr
          is a X server that outputs to a window on a pre-existing
          "host" X display. Unlike Xnest which is an X proxy, and
          thus limited to the capabilities of the host X server,
          Xephyr is a full X server which uses the host X server
          window as a "framebuffer" via fast SHM XImages.

   Xvfb
          is a virtual framebuffer X server that can run on
          machines with no display hardware and no physical input
          devices. It emulates a dumb framebuffer using virtual
          memory.

   Xquartz
          is an X server that interacts with the MacOS X native
          Aqua window system, displaying windows on the Mac
          desktop and accepting input from the Mac system devices,
          allowing X11 applications to be used in a native Mac
          desktop session.

   Xwin
          is an X server that runs under the Cygwin environment,
          interacting with the Microsoft Windows native window
          system, displaying windows on the Windows desktop and
          accepting input from the Windows system devices,
          allowing X11 applications to be used in a native Windows
          desktop session.

Xorg server

Loader and Modules

   The Xorg server relies on the operating system's native module
   loader support for handling program modules. The X server makes
   use of modules for video drivers, X server extensions, input
   device drivers, framebuffer layers, and internal components
   used by some drivers (like XAA & EXA).

   The module interfaces (both API and ABI) used in this release
   are subject to change without notice. While we will attempt to
   provide backward compatibility for the module interfaces in
   stable releases, we cannot guarantee this. Compatibility in the
   other direction is explicitly not guaranteed because new
   modules may rely on interfaces added in new releases, nor is
   compatibility across stable release branches (such as between
   Xorg 1.11 and 1.12).

Note about module security

   The Xorg server runs with root privileges, so the Xorg server
   loadable modules also run with these privileges. For this
   reason we recommend that all users be careful to only use
   loadable modules from reliable sources, otherwise the
   introduction of malware and contaminated code can occur and
   wreak havoc on your system.

Configuration File

   The Xorg 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.

   Note that this release features significant improvements for
   running the server without a configuration file, so many users
   may find that that they don't need a configuration file, or may
   rely on just snippets of configuration placed in the
   xorg.conf.d directory.

   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 driver
   tables) also.

   The recommended method for generating a configuration file is
   to use the Xorg server itself. Run as root:
        Xorg -configure

   and follow the instructions.

Command Line Options

   Command line options can be used to override some default
   parameters and parameters provided in the configuration file.
   Command line options available for use with all X servers in
   this release are described in the Xserver(1) manual page.
   Command line options specific to the Xorg server are described
   in the Xorg(1) manual page.

Multi-head

   Some multi-head configurations are supported in X11R7.7.
   Support for multiple PCI/AGP cards may require a kernel with
   changes to support VGA arbitration.

   One of the main problems is with drivers not sufficiently
   initializing cards that were not initialized 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).

Xinerama

   Xinerama is an X server extension that allows multiple physical
   screens connected to multiple video devices to behave as a
   single screen. With traditional multi-head in X11, windows
   cannot span or cross physical screens. Xinerama removes this
   limitation. Xinerama 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. Note that
   enabling Xinerama may disable certain other extensions which
   are not compatible with Xinerama.

DDC

   The VESA® Display Data Channel (DDC(TM)) standard allows the
   monitor to tell the video card (or in some cases the computer
   directly) about itself; particularly 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 disabled 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.

Changed behavior in handling information from DDC

   The X server previously used DDC information to detect screen
   size and pitch, and compute DPI automatically, allowing fonts
   and other UI elements to automatically scale to appropriate
   sizes. This mechanism worked reasonably well for many
   single-monitor cases, but did not compute accurate DPI values
   for multi-monitor cases or less common single-display setups.
   Thus, this autodetection has been removed, and the X server no
   longer tries to compute an appropriate DPI value. All users
   wanting fonts, physical measurement units, and other UI
   elements scaled appropriately for their display (including
   users for whom autodetection previously worked) must now set
   DPI or some other scaling factor explicitly, either via the X
   server's -dpi option, a DPI setting in their graphical
   enironment, or an alternate scaling mechanism provided by their
   environment.

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. The 3D core rendering component is provided
   by Mesa.

   Of note is that this release supports building the X server
   using the system-wide libdrm. Previously, drm was kept in the
   server's tree and loaded as a module, rather than using the
   standard OS mechanisms for managing shared libraries of code.
   This requires that the server be built using a version of
   libdrm of 2.3.0 or newer if it is to use DRM.

Terminate Server keystroke

   The Xorg server has previously allowed users to exit the server
   by pressing the keys Control + Alt + Backspace. While this
   function is still enabled by default in this release, the
   keymap data usually used with Xorg, from the xkeyboard-config
   project, has been modified to not map that sequence by default,
   in order to reduce the chance that inexperienced users will
   accidentally destroy their work.

   Users who wish to have this functionality available by default
   may enable it via the XKB configuration option
   "terminate:ctrl_alt_bksp". For instance, the setxkbmap command
   can be used to enable this by running:
        setxkbmap -option "terminate:ctrl_alt_bksp"

   The XKB Configuration Guide also includes an example
   xorg.conf.d file that sets the "terminate:ctrl_alt_bksp" option
   by default on all keyboards. Many desktop environments include
   XKB configuration options in their preferences to enable this
   as well.

Grab debugging keystrokes

   The Xorg server in this release provides various functions that
   can be mapped to keystrokes to aid in the debugging of programs
   with errant input grabs.

   The keysyms XF86LogGrabInfo and XF86LogWindowTree are defined
   to print information to the Xorg log file on the current set of
   input grabs, and the window tree of the current display. By
   default, these are available for use, but not mapped to any
   key.

   The keysym XF86Ungrab forces the X server to release all active
   grabs, which may leave the clients holding them in an
   inconsistent state. XF86ClearGrab goes further, killing the
   client connection of any client holding an active grab when it
   is pressed. These keystrokes are intended to allow developers
   to debug clients which are not properly releasing grabs or have
   problems occur while input is grabbed. Since grabs are a
   fundamental part of the X client security model, these
   keystrokes come with risks, such as the ability to bypass or
   kill screen locks without knowing the password, and thus are
   not available by default.

   Users who are willing to accept the security risk and wish to
   enable this functionality may do so via the XKB configuration
   option "grab:break_actions".

Security issue in older xkeyboard-config releases

   The xkeyboard-config data files included in this release have
   the grab disabling keys correctly disabled by default, but
   versions before xkeyboard-config 2.5 had them enabled, leading
   to the security risk described above. When upgrading to the X
   server in this release be sure to also ensure xkeyboard-config
   is a safe version. More details about this issue may be found
   in advisories for CVE-2012-0064.

X Server startup state

   The X servers in the X11R7.7 release now start by default with
   an empty black screen and do not draw the mouse cursor until a
   client sets the cursor image. To restore the classic behavior
   of starting with the grey weave pattern and × cursor, start the
   X server with the -retro option.

Font support

   Details about the font support in X11R7.7 can be found in the
   "Fonts in X11R7.7" document.

Default font installation directory

   Previous versions of X installed font files under the
   lib/X11/fonts subdirectory of the X installation directory (for
   instance, in X11R6 releases, /usr/X11R6/lib/X11/fonts was
   commonly used). This release uses the default installation path
   of the fonts subdirectory of the datadir setting from the GNU
   autoconf configuration. For instance, if the fonts are
   configured with ./configure --prefix=/usr, they will be
   installed under subdirectories of /usr/share/fonts/X11. The
   font module configure scripts all take an option of
   --with-fontrootdir=PATH to override the default. If
   --with-fontrootdir is not specified, the fontutil pkg-config
   file will be consulted to find the fontrootdir specified when
   the fontutil module was installed.

Bitmap font compression methods

   The X11R7.7 release supports PCF format bitmap fonts stored
   uncompressed or compressed via the compress, gzip, or bzip2
   programs. To utilize bzip2 compression, the libXfont and
   mkfontscale modules must be built with the --with-bzip2 -- all
   other methods are enabled by default.

   To specify which compression method to use when installing a
   font module from X11R7.7 the configure scripts accept an option
   of --with-compression=TYPE, where TYPE may be none, compress,
   gzip, or bzip2.

Type1 Font support

   Previous versions of X came with two Postscript Type1 font
   backends. The functionality from the "Type1" backend has been
   replaced by the Type1 support in the "FreeType" backend.

CID Font support

   The CID-keyed font format was designed by Adobe Systems for
   fonts with large character sets. The CID-keyed format is
   obsolete, as it has been superseded by other formats such as
   OpenType/CFF and support for CID-keyed fonts has been removed
   from X11.

Build changes and issues

Strict compilation flags

   Most of the modules in this release use stricter compiler flags
   when building with the GNU gcc, LLVM clang, Oracle Solaris
   Studio, or Intel compilers. These flags both enable more
   warnings, and promote some warnings to fatal errors in the
   build. If these flags cause your build to fail, you can disable
   the flags that turn these selected warnings into errors by
   adding --disable-selective-werror to the configure command for
   the affected module. If that is necessary for any X.Org
   modules, please report a bug in the xorg product on
   https://bugs.freedesktop.org/.

   Builders seeking even stricter compiler checks can instead pass
   --enable-strict-compilation to the configure command to make
   all warnings become errors.

Silent build rules

   Most of the modules in this release use the AM_SILENT_RULES
   option of GNU automake 1.11. When building the software, most
   output will show an abbreviated format for the commands being
   run, such as:
   CC   xmen.o

   To enable verbose output, showing all the arguments to the
   commands being run, add the flag V=1 to the make command line
   or add the flag --disable-silent-rules to the configure
   command.

New configure options for font modules

   The bitmap font modules now accept a configure option of
   --disable-all-encodings to set the default for all encodings to
   off, requiring builders to then pass --enable-<encoding> flags
   for each encoding to be built.

New configure options for documentation in modules

   As many more modules now contain documentation to be converted
   from DocBook XML to text, HTML, PostScript, and/or PDF formats,
   new standard options have been added to the configure macros to
   control the build of these in the modules.

   --with-xmlto=yes|no

   Enables or disables use of the xmlto command to translate
   DocBook XML to other formats. All DocBook XML conversions
   require use of this command.

   --with-fop=yes|no

   Enables or disables use of the Apache fop command to translate
   DocBook XML to PostScript and PDF formats.

   --enable-docs=yes|no

   Enables or disables the build and installation of all
   documentation except traditional man pages or those covered by
   the --enable-devel-docs and --enable-specs options.

   --enable-devel-docs=yes|no

   Enables or disables the build and installation of documentation
   for developers of the X.Org software modules.

   --enable-specs=yes|no

   Enables or disables the build and installation of the formal
   specification documents for protocols and APIs.

Miscellaneous

   This section describes other items of note for the X11R7.7
   release.

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 directories. 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.

Deprecated components and removal plans

   This section lists current plans for removal of obsolete or
   deprecated components in the X.Org releases. As our releases
   are open source, users who continue 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-devel@lists.x.org> to volunteer to take over
   maintainership, either inside or outside of the Xorg release
   process.

Future Removals

   DGA version 2

   DGA 2.0 is included in 7.7. Documentation for the client
   libraries can be found in the XDGA(3) man page. DGA should be
   considered deprecated; if you are relying on it, please let us
   know what you need it for so we can find better solutions. In
   this release, support has been removed for all DGA rendering
   and mapping code, leaving just mode setting and raw input
   device access.

   Input device discovery via HAL

   Xorg server 1.4 started using the HAL framework to discover
   connected input devices, receive notification of hotplug events
   for them, and to retrieve configuration parameters for them.
   The HAL maintainers have since deprecated HAL, so the X.Org
   developers have begun replacement with alternatives. As a
   result, configuration of input devices via HAL *.fdi files is
   no longer supported on Linux platforms using udev, and may not
   be supported on other platforms in future Xorg server releases.

   Nested and virtual X servers

   As described in the section called "Overview of X11R7.7", this
   release contains several X servers that either display onto
   another X server (Xephyr & Xnest), or render into a virtual
   memory framebuffer (Xvfb & Xfake). These may be replaced in a
   future release by use of the Xorg server with the
   xf86-video-nested and xf86-video-dummy drivers which perform
   the same tasks.

Removed in this Release

   Unmaintained drivers

   This release no longer contains the following drivers, due to
   lack of maintainers with relevant hardware. Existing driver
   versions may work with current Xorg servers, but they are not
   being actively updated to support Xorg driver API & ABI
   changes.
