Annotation of xsrc/xfree/xc/RELNOTES, Revision ! veego       1:                      Release Notes for XFree86[tm] 4.0.3

                      4: ! veego       5:                                 16 March 2001
1.1       veego       6:
                      7:                                   Abstract
                      9:      This document contains some information about the features present ! veego      10:      in XFree86 4.0.3 and their status.
1.1       veego      11:
                     12: 1.  Introduction to the 4.x Release Series
                     13: ! veego      14: XFree86 4.0 was the first official release of the new XFree86 4 series.
        !            15: XFree86 4.0.3 is the first update to 4.0.2, which is the latest full release
        !            16: in that series.  XFree86 4 represents a significant redesign of the XFree86 X
        !            17: server.  Not all of the hardware drivers from 3.3.x have been ported to 4.x
        !            18: yet, but conversely, 4.x has some hardware support not present in 3.3.x.  Our
        !            19: Driver Status document summarizes how the hardware driver support compares
        !            20: between 3.3.6 and 4.0.3.  Please check there first before downloading 4.0.3.
1.1       veego      21:
                     22: The 4.0.1 release introduced a new graphical configuration tool, "xf86cfg",
                     23: and a text mode interface was added to it for the 4.0.2 release.  It is work
                     24: in progress, but definitely worth trying out.  The trusty old text-based tool
                     25: "xf86config" can also be used for generating X server config files.  In addi-
                     26: tion to these tools, we've been working on a configuration tool that is
                     27: built-in to the X server.  It is included in the release, and it works well
                     28: for some hardware.  To try it out, just run (as root) "XFree86 -configure".
                     29: Each of these configuration options will give you a reasonable starting point
                     30: for a suitable configuration file.  We've put some effort into documenting ! veego      31: the 4.0.3 config file format, and you can find that information in the
1.1       veego      32: XF86Config manual page. Check that, the driver manual pages and the related
                     33: documentation for further information.
                     35: Before you go to download and install the binary distributions for this
                     36: release, please have a quick read through the Installation Document.  It may
                     37: save you some time and help you figure out which of the binary releases you
                     38: need.
                     39: ! veego      40: The next sections describe what has changed in the update release(s) as well
        !            41: as what is new in the latest full release (4.0.2).  The other sections below
        !            42: describe some of the new features and changes between 3.3.x and 4.0.  There
        !            43: are lot's of new features, and we definitely don't have enough space to cover
        !            44: them all here.

                    288:              o MouseKeys, mouse control only with the keyboard.
                    290:              o RepeatKeys, repeat rate and repeat delay.
                    292:              o SlowKeys, to avoid pressing keys accidentally, they're only

1.1       veego     315:
                    316:    o Many of the "misc" bdf fonts have been updated and extended, and a wider
                    317:      range of ISO-8859 subsets have been added.  These are now auto-generated
                    318:      from ISO-10646 encoded master fonts.
                    320:    o The ClearlyU ISO-10646 encoded fonts have been updated.
                    322:    o Functions to read keyboard input in locale independent UTF-8 encoding
                    323:      have been added to libX11: Xutf8LookupString, Xutf8ResetIC.
                    325:    o Functions to output strings in locale independent UTF-8 encoding have
                    326:      been added to libX11: Xutf8DrawString, Xutf8DrawImageString, Xutf8Tex-

                    329:    o Functions to convert between Compound Text or locale dependent encoding
                    330:      and UTF-8 have been added to libX11: Xutf8TextListToTextProperty,
                    331:      Xutf8TextPropertyToTextList. The converter between Compound Text and
                    332:      UTF-8 in Xlib has been improved; a round-trip conversion now correctly
                    333:      converts all graphic Unicode characters back and forth.
                    335:    o libXaw now offers selected text using both selection targets,
                    336:      UTF8_STRING and COMPOUND_TEXT.
                    338:    o Locales with UTF-8 encodings are now supported; but the UTF-8 displaying
                    339:      facilities are not adequate yet.
                    341:    o XKB keyboard definitions have been added and updated for some countries.

                    432: ! veego     433: 5.  Summary of XFree86 4.
1.1       veego     434:
                    435: Unlike XFree86 3.3.x where there are multiple X server binaries, each of ! veego     436: which drive different hardware, XFree86 4.0.3 has a single X server binary
1.1       veego     437: called XFree86.  This binary can either have one or more video drivers linked
                    438: in statically, or, more usually, dynamically load the video drivers and other
                    439: modules that are needed.
                    440: ! veego     441: XFree86 4.0.3 has X server support for most UNIX(R) and UNIX-like operating
1.1       veego     442: systems on Intel/x86 platforms, plus support for Linux on Alpha, PowerPC,
                    443: IA-64, Sparc, and Mips platforms, and for Darwin on PowerPC.  Work on support
                    444: for additional architectures and operating systems is in progress, and is
                    445: planned for future releases.
                    446: ! veego     447: 5.1  Loader and Modules
1.1       veego     448:
                    449: The XFree86 X server has a built-in run-time loader, donated by Metro Link
                    450: <URL:http://www.metrolink.com>.  This loader can load normal object files and
                    451: libraries in most of the commonly used formats.  Since the loader doesn't
                    452: rely on an operating system's native dynamic loader support, it works on
                    453: platforms that don't provide this feature, and makes it possible for the mod-
                    454: ules to be operating system independent (although not, of course, independent
                    455: of CPU architecture).  This means that a module compiled on Linux/x86 can be
                    456: loaded by an X server running on Solaris/x86, or FreeBSD, or even OS/2.
                    458: One of the main benefits of this loader is that when modules are updated,
                    459: they do not need to be recompiled for every different operating system.  In
                    460: the future we plan to take advantage of this to provide more frequent driver
                    461: module updates in between major releases.
                    462: ! veego     463: The loader in version 4.0.3 has support for Intel (x86), Alpha and PowerPC
1.1       veego     464: platforms.  It also has preliminary support for Sparc platforms.
                    466: The X server makes use of modules for video drivers, X server extensions,
                    467: font rasterisers, input device drivers, framebuffer layers (like mfb, cfb,
                    468: etc), and internal components used by some drivers (like XAA),
                    470: The module interfaces (API and ABI) used in this release is still subject to
                    471: change without notice.  While we will attempt to provide backward compatibil-
                    472: ity for the module interfaces as of the 4.0 release (meaning that 4.0 modules
                    473: will work with future core X server binaries), we cannot guarantee this.
                    475: Note about module security
                    477:      The XFree86 X server runs with root privileges, i.e.  the X server
                    478:      loadable modules also run with these privileges.  For this reason
                    479:      we recommend that all users be careful to only use loadable modules
                    480:      from reliable sources,  otherwise the introduction of viruses and
                    481:      contaminated code can occur and wreak havoc on your system.  We
                    482:      hope to have a mechanism for signing/verifying the modules that we
                    483:      provide available in a future release.
                    484: ! veego     485: 5.2  Configuration File
1.1       veego     486:
                    487: The X server configuration file format has been extended to handle some of
                    488: the new functionality.  The xf86config utility can be used to generate a
                    489: basic config file, that may require some manual editing.  The X server also
                    490: has preliminary support for generating a basic config file.  This is done by
                    491: running (as root) "XFree86 -configure".  Alternatively, the sample config
                    492: file XF86Config.eg that is installed in /usr/X11R6/lib/X11 may be used as a
                    493: starting point.  The XF86Setup utility is currently not usable, but work is
                    494: continuing in this area.
                    496: The main changes are covered here, but please refer to the XF86Config manual
                    497: page for more comprehensive information:
                    499:    o The Module section is used to load server extension modules and font
                    500:      modules, but not XInput drivers.  The .so suffix should no longer be
                    501:      specified with module names.  Options may be supplied for modules by
                    502:      loading the module via a SubSection instead of the usual Load keyword.
                    503:      The bitmap module is the only font module that is loaded by default.  No
                    504:      server extensions are loaded by default, but some are built-in to the
                    505:      server.  It is strongly recommended that the extension module containing
                    506:      a range of small miscellaneous extensions (extmod) be loaded because
                    507:      some commonly used things won't work correctly without it.  The follow-
                    508:      ing example shows how to load all the server extensions plus the Type1
                    509:      and TrueType fonts support, and a commented example that shows how to
                    510:      pass options to an extension (this one is for loading the misc exten-
                    511:      sions (extmod) with the XFree86-VidModeExtension disabled):
                    513:                Section "Module"
                    515:                    Load "dbe"
                    516:                    Load "record"
                    517:                    Load "glx"
                    518:                    Load "pex5"
                    519:                    Load "xie"
                    520:                    Load "extmod"
                    522:                    Load "type1"
                    523:                    Load "freetype"
                    525:                  # SubSection "extmod"
                    526:                  #     Option "Omit XFree86-VidModeExtension"
                    527:                  # EndSubSection
                    529:                EndSection
                    531:    o Option flags have been extended and are now used more widely in the con-
                    532:      fig file.  Options flags come in two main types.  The first type is
                    533:      exactly like the old form:
                    535:                    Option "name"
                    537:      where the option just has a name specified.  The name is case insensi-
                    538:      tive, and white space and underscore characters are ignored.  The second
                    539:      type consists of a name and a value:
                    541:                    Option "name" "value"
                    543:      The value is passed transparently as a string to the code that uses the
                    544:      option.  Common value formats are integer, boolean, real, string and
                    545:      frequency.  The following boolean option values are recognised as mean-
                    546:      ing TRUE: "true", "yes", "on", "1", and no value.  The values recognised
                    547:      as FALSE are "false", "no", "off", "0".  In addition to this, "no" may
                    548:      be prepended to the name of a boolean option to indicate that it is
                    549:      false.  Frequency options can have the strings Hz, kHz, or MHz appended
                    550:      to the numerical value specified.
                    552:      Note: the value must always be enclosed in double quotes ("), even when
                    553:      it is numerical.
                    555:    o The ServerFlags section now accepts its parameters as Options instead of
                    556:      as special keywords.  The older keyword format is still recognised for
                    557:      compatibility purposes, but is deprecated and support for it will likely
                    558:      be dropped in a future release.  The DPMS and screen save timeout values
                    559:      are now specified in the ServerFlags section rather than elsewhere
                    560:      (because they are global parameters, not screen-specific).  This example
                    561:      shows the defaults for these:
                    563:                    Option "blank time"    "10"
                    564:                    Option "standby time"  "20"
                    565:                    Option "suspend time"  "30"
                    566:                    Option "off time"      "40"
                    568:    o The Keyboard, Pointer and XInput sections have been replaced by a more
                    569:      general InputDevice section.  The old Keyboard and Pointer sections are
                    570:      still recognised for compatibility purposes, but they are discommended
                    571:      and support for them may be dropped in future releases.  The old XInput
                    572:      sections are no longer recognised.  The keywords from the old sections
                    573:      are expressed as Options in the InputDevice sections.  The following
                    574:      example shows typical InputDevice sections for the core mouse and key-
                    575:      board.
                    577:                Section "InputDevice"
                    578:                    Identifier  "Keyboard 1"
                    579:                    Driver      "keyboard"
                    580:                    Option      "AutoRepeat" "500 5"
                    581:                    Option      "XkbModel"   "pc104"
                    582:                    Option      "XkbLayout"  "us"
                    583:                EndSection
                    585:                Section "InputDevice"
                    586:                    Identifier  "Mouse 1"
                    587:                    Driver      "mouse"
                    588:                    Option      "Protocol"   "PS/2"
                    589:                    Option      "Device"     "/dev/mouse"
                    590:                    Option     "SampleRate" "80"
                    591:                EndSection
                    593:    o The Monitor section is mostly unchanged.  The main difference is that a
                    594:      set of VESA modes is defined internally in the server, and so for most
                    595:      monitors, it isn't necessary to specify any modes explicitly in the Mon-
                    596:      itor section.  There is also a new Modes section that can be used to
                    597:      define a set of modes separately from the Monitor section, and the Moni-
                    598:      tor section may "include" them with the "UseModes" keyword.  The Monitor
                    599:      section may also include Options.  Options that are monitor-specific,
                    600:      like the "DPMS" and "Sync on Green" options are best specified in the
                    601:      Monitor sections.
                    603:    o The Device sections are mostly unchanged.  The main difference is the
                    604:      new (and mandatory) Driver keyword that specifies which video driver
                    605:      should be loaded to drive the video card.  Another difference is the
                    606:      BusID keyword that is used to specify which of possibly multiple video
                    607:      cards the Device section is for.  The following is an example for a
                    608:      Matrox card:
                    610:                Section "Device"
                    611:                    Identifier "MGA 1"
                    612:                    Driver     "mga"
                    613:                    BusID      "PCI:1:0:0"
                    614:                EndSection
                    616:    o The Screen sections are mostly unchanged.  The old Driver keyword is no
                    617:      longer used, and a mandatory Identifier keyword has been added.  The
                    618:      DefaultColorDepth keyword has been renamed to DefaultDepth.
                    620:    o A new section called ServerLayout has been added to allow the layout of
                    621:      the screens and the selection of input devices to be specified.  The
                    622:      ServerLayout sections may also include options that are normally found
                    623:      in the ServerFlags section.  Multiple ServerLayout sections may be pre-
                    624:      sent, and selected from the command line.  The following example shows a
                    625:      ServerLayout section for a dual-headed configuration with two Matrox
                    626:      cards, and two mice:
                    628:                Section "ServerLayout"
                    629:                    Identifier  "Layout 1"
                    630:                    Screen      "MGA 1"
                    631:                    Screen      "MGA 2" RightOf "MGA 1"
                    632:                    InputDevice "Keyboard 1" "CoreKeyboard"
                    633:                    InputDevice "Mouse 1"    "CorePointer"
                    634:                    InputDevice "Mouse 2"    "SendCoreEvents"
                    635:                    Option      "BlankTime"  "5"
                    636:                EndSection
                    638:      See the XF86Config man page for a more detailed explanation of the for-
                    639:      mat of the new ServerLayout section.
                    641: The config file search patch has been extended, with the directories /etc/X11
                    642: and /usr/X11R6/etc/X11 being added.  The full search path details are docu-
                    643: mented in the XF86Config manual page.
                    644: ! veego     645: 5.3  Command Line Options
1.1       veego     646:
                    647: The following new X server command line options have been added:
                    649:      -depth n
                    651:           This specifies the colour depth that the server is run-
                    652:           ning at.  The default is 8 for most drivers.  Most
                    653:           drivers support the values 8, 15, 16 and 24.  Some
                    654:           drivers also support the values 1 and 4.  Some drivers
                    655:           may also support other depths.  Note that the depth is
                    656:           different from the ``bpp'' that was specified with previ-
                    657:           ous versions.  The depth is the number of bits in each
                    658:           pixel that are significant in determining the pixel's
                    659:           value.  The bpp is the total size occupied by each pixel,
                    660:           including bits that are not used.  The old -bpp option is
                    661:           no longer recognised because it isn't a good way of spec-
                    662:           ifying the server behaviour.
                    664:      -fbbpp n
                    666:           This specifies the bpp format to use for the framebuffer.
                    667:           This may be used in 24-bit mode to force a framebuffer
                    668:           format that is different from what the driver chooses by
                    669:           default.  In most cases there should be no need to use
                    670:           this option.
                    672:      -pixmap24
                    674:           This specifies that the client-side pixmap format should
                    675:           be the packed 24-bit format that was often used by the
                    676:           3.3.x servers.  The default is the more common 32-bit
                    677:           format.  There should normally be no need to use this
                    678:           option.
                    680:      -pixmap32
                    682:           This specifies that the client-side pixmap format should
                    683:           be the sparse 32-bit format.  This is the default, so
                    684:           there should normally be no need to use this option.
                    686:      -layout name
                    688:           This specifies which ServerLayout section in the config
                    689:           file to use.  When this option is not specified, the
                    690:           first ServerLayout section is used.  When there is no
                    691:           ServerLayout section, the first Screen section is used.
                    693:      -screen name
                    695:           This specifies which Screen section in the config file to
                    696:           use.  When this option is not specified, the first
                    697:           ServerLayout section is used.  When there is no Server-
                    698:           Layout section, the first Screen section is used.
                    700:      -keyboard name
                    702:           This specifies which InputDevice section in the config
                    703:           file to use for the core keyboard.  This option may be
                    704:           used in conjunction with the -screen option.
                    706:      -pointer name
                    708:           This specifies which InputDevice section in the config
                    709:           file to use for the core pointer.  This option may be
                    710:           used in conjunction with the -screen option.
                    712:      -modulepath path
                    714:           This specifies the module search path.  The path should
                    715:           be a comma-separated list of absolute directory paths to
                    716:           search for server modules.  When specified here, it over-
                    717:           rides the value specified in the config file.  This
                    718:           option is only available when the server is started by
                    719:           the root user.
                    721:      -logfile file
                    723:           This specifies the log file name.  When specified here,
                    724:           it overrides the default value.  This option is only
                    725:           available when the server is started by the root user.
                    727:      -scanpci
                    729:           This specifies that the scanpci module should be loaded
                    730:           and executed.  This does a scan of the PCI bus.
                    732:      -logverbose [n]
                    734:           This options specifies the verbosity level to use for the
                    735:           log file.  The default is 3.
                    737: The following X server command line options have been changed since 3.3.x:
                    739:      -verbose [n]
                    741:           This option specifies the verbosity level to use for the
                    742:           server messages that get written to stderr.  It may be
                    743:           specified multiple times to increase the verbosity level
                    744:           (as with 3.3.x), or the verbosity level may be specified

                    759: from scratch for XFree86 4.x.  Most drivers implement acceleration by making
                    760: use of the XAA module.

1.1       veego     763:
                    764: Some multi-head configurations are supported in XFree86 4.x, primarily with
                    765: multiple PCI/AGP cards.  However, this is an area that is still being worked
                    766: on, and we expect that the range of configurations for which it works well
                    767: will increase in future releases.  A configuration that is known to work well
                    768: in most cases is multiple (supported) Matrox cards.
                    770: One of the main problems is with drivers not sufficiently initialising cards
                    771: that were not initialised at boot time.  This has been improved somewhat with
                    772: the INT10 support that is used by most drivers (which allows secondary card
                    773: to be "soft-booted", but in some cases there are other issues that still need
                    774: to be resolved.  Some combinations can be made to work better by changing
                    775: which card is the primary card (either by using a different PCI slot, or by
                    776: changing the system BIOS's preference for the primary card).

1.1       veego     779:
                    780: Xinerama is an X server extension that allows multiple physical screens to
                    781: behave as a single screen.  With traditional multi-head in X11, windows can-
                    782: not span or cross physical screens.  Xinerama removes this limitation.  Xin-
                    783: erama does, however, require that the physical screens all have the same root
                    784: depth, so it isn't possible, for example, to use an 8-bit screen together
                    785: with a 16-bit screen in Xinerama mode.
                    787: Xinerama is not enabled by default, and can be enabled with the +xinerama
                    788: command line option for the X server.
                    790: Xinerama was included with X11R6.4.  The version included in XFree86 4.x was
                    791: completely rewritten for improved performance and correctness.
                    793: Known problems:
                    795:    o Most window managers are not Xinerama-aware, and so some operations like
                    796:      window placement and resizing might not behave in an ideal way.  This is
                    797:      an issue that needs to be dealt with in the individual window managers,
                    798:      and isn't specifically an XFree86 problem.

1.1       veego     808:
                    809: The VESA(R) Display Data Channel (DDC[tm]) standard allows the monitor to
                    810: tell the video card (or on some cases the computer directly) about itself;
                    811: particularly the supported screen resolutions and refresh rates.
                    813: Partial or complete DDC support is available in most of the video drivers.
                    814: DDC is enabled by default, but can be disabled with a "Device" section entry:
                    815: Option "NoDDC".  We have support for DDC versions 1 and 2; these can be dis-
                    816: abled independently with Option "NoDDC1" and Option "NoDDC2".
                    818: At startup the server prints out DDC information from the display, but it
                    819: does not yet use it the determine modelines.  For some drivers, the X
                    820: server's new -configure option uses the DDC information when generating the
                    821: config file.
                    823: Changed behavior caused by DDC. Several drivers uses DDC information to set
                    824: the screen size and pitch.  This can be overridden by explicitly resetting it
                    825: to the and non-DDC default value 75 with the -dpi 75 command line option for
                    826: the X server, or by specifying appropriate screen dimensions with the "Dis-

1.1       veego     859:

                    862: ing model derived from Plan 9 based on Porter/Duff image composition rather
                    863: than binary raster operations.
                    865: Using simple compositing operators provided by most hardware, Render can draw

                    867: overlays and other image operations not possible with the core X rendering

                    872: geometric primitives and affine transformation of images.
                    874: Unlike the core protocol, Render provides no font support for applications,
                    875: rather it allows applications to upload glyphs for display on the screen.
                    876: This allows the client greater control over text rendering and complete

                    883: using the FreeType library, version 2.  FreeType currently supports Type1 and
                    884: TrueType font files, a future release is expected to support BDF and PCF
                    885: files as well, so Render applications will have access to the complete range
                    886: of fonts available to core applications.  One important thing to note is that
                    887: Xft uses the vertical size of the monitor to compute accurate pixel sizes for
                    888: provided point sizes; if your monitor doesn't provide accurate information
                    889: via DDC, you may want to add that information to XF86Config.
                    891: To allow a graceful transition for applications moving from core text render-
                    892: ing to the Render extension, Xft can use either core fonts or FreeType and
                    893: the Render extension for text.  By default, Xft is configured to support only
                    894: core fonts, see the section on building FreeType support for the changes
                    895: needed to add FreeType/Render fonts.
                    897: The Xft library uses a configuration file, XftConfig, which contains informa-
                    898: tion about which directories contain font files and also provides a sophisti-
                    899: cated font aliasing mechanism.  Documentation for that file is included in

                    908: To build FreeType support for Xft, first FreeType must be built and
                    909: installed, either from the sources included in XFree86 in extras/freetype2 or
                    910: from another FreeType (version 2.0.1 or later) release.  Early FreeType ver-

                    915: Second, XFree86 needs to know the installed location for FreeType, usually

                    929: By default, xterm uses core fonts through the standard core API.  It has two
                    930: command line options and associated resources to direct it to use Xft

                    971:      time.
                    973:    o Since Xpm was integrated into XFree86, programs linked with the new Xaw
                    974:      library     will also link with Xpm. This allows for color background
                    975:      pixmaps, and also for shaped widgets.
                    977:    o The text widget is the widget that will present more changes. These

                   1053:    o A first tentative to add programming modes was done. Currently, there is
                   1054:      one mode:
                   1056:         o C-mode: this mode is expected to be stable, and fully usable.

1.1       veego    1078:
                   1079: XFree86 4.x has a ``fontenc'' layer to allow the scalable font backends to
                   1080: use a common method of font re-encoding.  This re-encoding makes it possible
                   1081: to uses fonts in encodings other than their their native encoding.  This
                   1082: layer is used by the Type1 and Speedo backends and the `xfsft' version of the
                   1083: TrueType backend.  The `X-TrueType' version of the TrueType backend uses a
                   1084: different re-encoding method based on loadable encoding modules.

                   1090: consumption.  For non-local clients, the glyph metrics array is transmitted

                   1103:      automatically generated from the new ISO10646-1 master fonts.
                   1105:    o Some ``-misc-fixed-*'' BDF ISO10646-1 fonts now cover a comprehensive

                   1120:    o ISO 10646/Unicode UTF-8 Level 1 support added to xterm (enabled with the
                   1121:      -u8 option).
                   1123:    o Both the xfsft (the "freetype" module) and the X-TrueType (the "xtt"
