<title>Introduction to the X11R&relvers; Release</title>
<para>
X11R&relvers; was the &whichfullrel; modular release of the
<productname>X Window System</productname>.
</para>
<para>
Unlike X11R1 through X11R6.9, X11R7.x releases were 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 were made by
&ldquo;rolling up&rdquo; the individual module releases into a
collection that is often affectionately called the
&ldquo;<foreignphrase>katamari</foreignphrase>&rdquo; by the developers.
</para>
<para>
The X11R&relvers; 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.
</para>
<para>
Once their window system build is established, most builders watch for
announcements of individual module updates on the <ulink
url="https://lists.x.org/mailman/listinfo/xorg-announce"
>xorg-announce mailing list</ulink> and update to those as needed.
</para>
<para>
There are no plans for any further
&ldquo;<foreignphrase>katamari</foreignphrase>&rdquo; releases of the
X Window System at this time, only releases of the individual modules
are planned for now.
</para>
<para>
For help with how to build and develop in the modular tree see the
<ulink url="https://wiki.x.org/wiki/ModularDevelopersGuide">Modular
Developer's Guide</ulink> in the X.Org wiki.
</para>
<para>
We encourage you to report bugs, and to
submit bug fixes and enhancements via
<ulink url="https://gitlab.freedesktop.org/xorg">the gitlab.freedesktop.org code management system</ulink>.
More details on patch submission and review process are available on the
<ulink

SubmittingPatches</ulink> page of the X.Org wiki.
</para>
<para>
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 module releases.

<para>
<firstterm>Multi-touch</firstterm> 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.
</para>
</listitem>
<listitem>
<para>
Additional <firstterm>Xinput extension</firstterm> 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.
</para>
</listitem>
<listitem>
<para>
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 <filename>/usr/share/doc/</filename>. They
are also posted on the X.Org website at
<ulink url="https://www.x.org/releases/X11R7.7/" />.

<listitem>
<para>
<firstterm>Fence</firstterm> objects are now available in Version
3.1 of the <olink targetdoc="sync" targetptr="sync">Synchronization
(<quote>Sync</quote>) extension</olink>. These allow clients
to create a object that is either in <quote>triggered</quote>
or <quote>not-triggered</quote> 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 <filename class="libraryfile">libxcb-sync</filename> and
<filename class="libraryfile">libXext</filename> API's.
</para>
</listitem>
<listitem>
<para>
<firstterm>Pointer barriers</firstterm> 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.
</para>
</listitem>
<!-- Skip for 7.7, since only the proto headers landed in time.
Restore for 7.8 once the server & client bits land.
<listitem>
<para>
Version 1.2 of the X Resource extension provides new requests
that allow clients to query for additional identification
information about other clients, such as their process id,
and to request size information about the resources clients
have allocated in the X server, to allow better observability
and easier debugging of client resource allocations in the server.

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 accessible via the XCB APIs. Some of this effort was funded
by past Google Summer of Code projects.

On most platforms, X11R&relvers; has a single hardware-driving
X server binary called <command>Xorg</command>. This binary can
dynamically load the video drivers, input drivers, and other modules
that are needed.
<command>Xorg</command> currently has support for Linux, Solaris,
and some BSD OSs on Alpha, PowerPC, IA-64, AMD64, Intel x86, Sparc,
and MIPS platforms.
</para>

<sect2 id='Xorg_server'>
<title>Xorg server</title>
<sect3 id='Loader_and_Modules'>
<title>Loader and Modules</title>
<para>
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 &amp; EXA).
</para>
<para>
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).
</para>
<warning>
<title>Note about module security</title>
<para>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.
</para></warning>
</sect3>
<sect3 id='Configuration_File'>
<title>Configuration File</title>
<para>
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 <ulink url="xorg.conf.5.html">
xorg.conf(5)</ulink> manual page.
</para>
<para>
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
<filename class="directory">xorg.conf.d</filename> directory.
</para>
<para>
If you do need to customize the configuration file, see the <ulink
url="xorg.conf.5.html"
>xorg.conf manual page</ulink> . You can also
check the driver-specific manual pages and the related
documentation (found at <xref linkend="drivertables"></xref>) also.
</para>
<para>
The recommended method for generating a configuration file is to use
the Xorg server itself. Run as root:
<screen>
Xorg -configure
</screen>
and follow the instructions.
</para>
</sect3>
<sect3 id='Command_Line_Options'>
<title>Command Line Options</title>
<para>
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 <ulink
url="Xserver.1.html">Xserver(1)</ulink> manual page.
Command line options specific to the Xorg server are described in
the <ulink url="Xorg.1.html">Xorg(1)</ulink> manual page.
</para>
</sect3>
<sect3 id='Multi-head'>
<title>Multi-head</title>
<para>
Some multi-head configurations are supported in X11R&relvers;.
Support for multiple PCI/AGP cards may require a kernel with
changes to support VGA arbitration.
</para>
<para>
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).
</para>
</sect3>
<sect3 id='Xinerama'>
<title>Xinerama</title>
<para>
<firstterm>Xinerama</firstterm> 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.
</para>
<para>
Xinerama is not enabled by default, and can be enabled with the
<option>+xinerama</option> command line option for the X server.
Note that enabling Xinerama may disable certain other extensions
which are not compatible with Xinerama.
</para>
</sect3>
<sect3 id='DDC'>
<title>DDC</title>
<para>
The <acronym>VESA</acronym>&reg; Display Data Channel
(<acronym><trademark>DDC</trademark></acronym>) 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.
</para>
<para>
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: <literal remap="tt">Option
"NoDDC"</literal>. We have support for DDC versions 1 and 2; these
can be disabled independently with <literal remap="tt">Option
"NoDDC1"</literal> and <literal remap="tt">Option
"NoDDC2"</literal>.
</para>
<para>
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.

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
<option>-dpi</option> option, a DPI setting in their graphical
environment, or an alternate scaling mechanism provided by their
environment.

Direct rendered OpenGL&reg; support is provided for several
hardware platforms by the Direct Rendering Infrastructure (DRI).
Further information about DRI can be found at the <ulink

<para>
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.

<sect3 id='Terminate_Server_keystroke'>
<title>Terminate Server keystroke</title>
<para>
The Xorg server has previously allowed users to exit the server
by pressing the keys
<keycap function="control">Control</keycap> +
<keycap function="alt">Alt</keycap> +
<keycap function="backspace">Backspace</keycap>.
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.
</para>
<para>
Users who wish to have this functionality available by default
may enable it via the XKB configuration option
&ldquo;<option>terminate:ctrl_alt_bksp</option>&rdquo;. For
instance, the <command>setxkbmap</command> command can be used
to enable this by running:
<screen>
setxkbmap -option "terminate:ctrl_alt_bksp"
</screen>
<olink targetdoc="XKB-Config" targetptr="XKB-Config">The XKB
Configuration Guide</olink> also includes
<olink targetdoc="XKB-Config" targetptr="zap">an example
xorg.conf.d file that sets the
&ldquo;<option>terminate:ctrl_alt_bksp</option>&rdquo;
option by default on all keyboards</olink>.
Many desktop environments include XKB configuration options in
their preferences to enable this as well.

<sect3 id='Grab_debugging_keystrokes'>
<title>Grab debugging keystrokes</title>
<para>
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.
</para>
<para>
The keysyms <keysym>XF86LogGrabInfo</keysym> and
<keysym>XF86LogWindowTree</keysym> 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.
</para>
<para>
The keysym <keysym>XF86Ungrab</keysym> forces the X server
to release all active grabs, which may leave the clients holding
them in an inconsistent state. <keysym>XF86ClearGrab</keysym>
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.
</para>
<para>
Users who are willing to accept the security risk and wish to enable
this functionality may do so via the XKB configuration option
&ldquo;<option>grab:break_actions</option>&rdquo;.
</para>
<warning>
<title>Security issue in older xkeyboard-config releases</title>
<para>
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 <ulink

a client sets the cursor image. To restore the classic behavior
of starting with the grey weave pattern and &times; cursor, start
the X server with the <option>-retro</option> option.

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

<command>gzip</command>, or <command>bzip2</command> programs.
To utilize bzip2 compression, the <literal>libXfont</literal>
and <command>mkfontscale</command> modules must be built with
the <option>--with-bzip2</option> &mdash; all other methods are
enabled by default.
</para>
<para>
To specify which compression method to use when installing
a font module from X11R&relvers; the configure scripts accept

<sect2 id='Strict_compilation_flags'>
<title>Strict compilation flags</title>
<para>
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
<option>--disable-selective-werror</option> to the configure command
for the affected module. If that is necessary for any X.Org modules,
please report a bug in the project for that module on
<ulink url="https://gitlab.freedesktop.org/xorg" />.
</para>
<para>
Builders seeking even stricter compiler checks can instead pass
<option>--enable-strict-compilation</option> to the configure command
to make all warnings become errors.

<sect2 id='Silent_build_rules'>
<title>Silent build rules</title>
<para>
Most of the modules in this release use the

When building the software, most output will show an abbreviated
format for the commands being run, such as:
<screen>
CC xmen.o
</screen>
To enable verbose output, showing all the arguments to the commands
being run, add the flag <option>V=1</option> to the
<command>make</command> command line or add the flag
<option>--disable-silent-rules</option> to the configure command.

<sect2 id='Socket_directory_ownership_and_permissions'>
<title>Socket directory ownership and permissions</title>
<para>
The socket directories created in <filename>/tmp</filename>
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:
<screen>
/tmp/.font-unix
/tmp/.ICE-unix
/tmp/.X11-unix
</screen>
These directories are used by the font server
(<command>xfs</command>), applications using the Inter-Client
Exchange protocol (<acronym>ICE</acronym>) and the X server,
respectively.
</para>
<para>
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 <filename class="directory">/tmp</filename> dir is
persistent. They could be created at boot time by the system's
boot scripts (e.g., the <filename class="directory" >init.d</filename>
scripts). Or, they could be created by PAM modules at service
startup or user login time.
</para>
<para>
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.

<title>Deprecated components and removal plans</title>
<para>
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 <email>xorg-devel@lists.x.org</email> to volunteer to
take over maintainership, either inside or outside of the Xorg release
process.
