1.  What and Where is XFree86?

XFree86 3.3.3 is a port of X11R6.3 that supports several versions of Intel-
based Unix.  It is derived from X386 1.2, which was the X server distributed
with X11R5.  This release consists of many new features and performance
improvements as well as many bug fixes.  The release is available as source
patches against the X Consortium X11R6.3 code, as well as binary distributions
for many architectures.

See the Copyright Notice.

The sources for XFree86 are available by anonymous ftp from:

ftp://ftp.XFree86.org/pub/XFree86/current

Binaries for NetBSD 1.2 are available from:
ftp://ftp.XFree86.org/pub/XFree86/current/binaries/NetBSD-1.2

Binaries for NetBSD 1.3 and later are available from:
ftp://ftp.XFree86.org/pub/XFree86/current/binaries/NetBSD-1.3

A list of mirror sites is provided by ftp://ftp.XFree86.org/pub/XFree86/MIRRORS

Other NetBSD versions:

These binaries are not compatible with earlier NetBSD versions. If you're still
running NetBSD 0.9, 1.0 or 1.1, you should think about upgrading to a newer
version of NetBSD first.

If you don't upgrade, you'll have to build XFree86 from the sources.  XFree86
3.3.3 should compile cleanly under earlier versions of NetBSD, although this
has not been tested.

XFree86 3.3.3 also builds on NetBSD/sparc. See section Building on other archi-
tectures (section 8.5, page 8) for details.

The client side of XFree86 also builds on NetBSD/alpha and many other architec-
ture supported by NetBSD.

XFree86 3.3.3 also supports NetBSD on PC98 machines.

2.  Bug Reports for This Document

Send email to matthieu@laas.fr (Matthieu Herrb) or XFree86@XFree86.org if you
have comments or suggestions about this file and we'll revise it.


3.  New features in this release

See the Release Notes for non-OS dependent new features in XFree86 3.3.3.


4.  Installing the Binaries

Refer to section 5 of the Release Notes  for detailed installation instruc-
tions.


5.  Configuring X for Your Hardware

The /etc/XF86Config file tells the X server what kind of monitor, video card
and mouse you have.  You must create it to tell the server what specific hard-
ware you have.

The easiest way to create this file is to run the XF86Setup utility as root.
Refer to QuickStart.doc for details about its use.

You'll need info on your hardware:

   o Your mouse type, baud rate and its /dev entry.

   o The video card's chipset (e.g. ET4000, S3, etc).

   o Your monitor's sync frequencies.

The recommended way to generate an XF86Config file is to use the XF86Setup
utility.  The xf86config text utility is still there for the (few) cases where
XF86Setup can't be used. Also, there is a sample file installed as
/usr/X11R6/lib/X11/XF86Config.eg, which can be used as a starting point.

For details about the XF86Config file format, refer to the XF86Config(5) manual
page.

Once you've set up a XF86Config file, you can fine tune the video modes with
the xvidtune utility.

5.1  About mouse configuration

If your serial mouse does not work try using kermit or tip to connect to the
mouse serial port and verify that it does indeed generate characters.

The NetBSD pms mouse driver handles PS/2 style mice as Busmouse. Specify the
protocol as ``busmouse'' in the mouse section of your XF86Config file if you're
using a PS/2 mouse.









README for XFree86 3.3.3 on NetBSD                                            3



Only standard PS/2 mice are supported by this driver. Newest PS/2 mice that
send more than three bytes at a time (especially Intellimouse, or MouseMan+
with a ``3D'' roller) are not supported yet.

See README.mouse  for general instruction on mouse configuration in XFree86.

5.2  Other input devices

XFree86  supports the dynamic loading of drivers for external input devices
using the XInput extension. Currently supported devices are:

   o Joystick (xf86Jstk.so)

   o Wacom tablets (Wacom IV protocol only, xf86Wacom.so)

   o SummaSketch tablets (xf86Summa.so)

   o Elographics touchscreen (xf86Elo.so)

To use a specific device, add the line

     load "module"


in the Module section of XF86Config, where module is the name of the .so file
corresponding to your device.  You also need to set up a XInput section in
XF86Config.  Refer to the XF86Config(5) man page for detailed configuration
instructions.

You can then change the device used to drive the X pointer with the xset-
pointer(1) command.

For joystick support, you'll need to install the joystick device driver in the
kernel. It is included in NetBSD 1.2. See joy(4) for details.

5.3  Configuring PEX and XIE extensions

The PEX and XIE extensions are  supported as external modules.  If you want to
have access to these extensions, add the following lines to the Module section
of XF86Config:

        load    "pex5.so"
        load    "xie.so"


6.  Running X

8mb of memory is a recommended minimum for running X.  The server, window man-
ager and an xterm take about 4 Mb of memory themselves.  On a 4Mb system that
would leave nothing left over for other applications like gcc that expect a few
meg free.  X will work with 4Mb of memory, but in practice compilation while
running X can take 5 or 10 times as long due to constant paging.

The easiest way for new users to start X windows is to type:








README for XFree86 3.3.3 on NetBSD                                            4



     startx >& startx.log


Error messages are lost unless you redirect them because the server takes over
the screen.

To get out of X windows, type: ``exit'' in the console xterm.  You can cus-
tomize your X by creating .xinitrc, .xserverrc, and .twmrc files in your home
directory as described in the xinit and startx man pages.

6.1  Starting Xdm, the display manager

To start the display manager, log in as root on the console and type: ``xdm
-nodaemon''.

You can start xdm automatically on bootup by disabling the console getty and
adding the following code to /etc/rc.local:

       if [ -x /usr/X11R6/bin/xdm ]; then
         echo -n ' xdm'; /usr/X11R6/bin/xdm
       fi

To disable the console getty, change ``on'' to ``off'' in the console entry in
/etc/ttys:

      ttyv0    "/usr/libexec/getty Pc"  pc   off secure

Note that the binary distributions of XFree86 for NetBSD don't include support
for the XDM-AUTHORIZATION-1 protocol.


7.  Kernel Support for X

To make sure X support is enabled under NetBSD, the following line must be in
your config file in /sys/arch/i386/conf:

     options XSERVER, UCONSOLE

7.1  Console drivers

The server supports the two standard NetBSD/i386 console drivers: pccons and
pcvt. They are detected at runtime and no configuration of the server itself is
required.

The pccons driver is the most widely tested and is the console driver contained
in the NetBSD binary distribution's kernels.

The pcvt console driver is bundled with NetBSD. The pcvt X mode is compatible
with the pccons driver X mode. It offers several virtual consoles and interna-
tional keyboard support. In order to use this driver, change the line:

     device          pc0     at isa? port "IO_KBD" irq 1

to








README for XFree86 3.3.3 on NetBSD                                            5



     device         vt0     at isa? port "IO_KBD" irq 1

in your kernel config file, and rebuild and install your kernel.

XFree86 will also run with the wscons console driver in NetBSD-current. For
now, it uses the pcvt compatibility mode, so be sure to have the line:

     options         WSDISPLAY_COMPAT_PCVT           # emulate some ioctls


in your kernel configuration file if you're using wscons.

7.2  Aperture Driver

By default NetBSD 0.9C and higher include the BSD 4.4 kernel security feature
that disable access to the /dev/mem device when in multi-users mode. But
XFree86 servers can take advantage (or require) linear access to the display
memory.

Moset recent accelerated servers require linear memory access, some other can
take advantage of it, but do not require it.

There are two ways to allow XFree86 to access linear memory:

The first way is to disable the kernel security feature by adding `option INSE-
CURE' in the kernel configuration file and build a new kernel.

The second way is to install the aperture driver: You can get the aperture
driver sources from ftp://ftp.netbsd.org/pub/NetBSD/arch/i386/apNetBSD.shar.

How to activate it is highly dependent from your exact operating system ver-
sion:

   o  NetBSD 1.0, 1.1, 1.2, 1.2.1:

     Add the following lines to the end of /etc/rc.local:

           KERNDIR=/usr/X11R6/lib/X11/kernel
           if [ -f ${KERNDIR}/ap.o ]; then
             modload -o ${KERNDIR}/ap -e ap -p ${KERNDIR}/apinstall ${KERNDIR}/ap.o
           fi

   o  NetBSD 1.2D and later

     Add the following line to  /etc/lkm.conf:

          /usr/X11R6/lib/X11/kernel/ap.o  -  ap /usr/X11R6/lib/X11/kernel/apinstall -



   o  NetBSD 1.2G, 1.3 and later

     The lkm.conf format changed in 1.2G.  Add the following line to
     /etc/lkm.conf:








README for XFree86 3.3.3 on NetBSD                                            6



          /usr/X11R6/lib/X11/kernel/ap.o  -  ap /usr/X11R6/lib/X11/kernel/apinstall - -AFTERMOUNT



Reboot your system. XFree86 will auto-detect the aperture driver if available.

Warning: if you boot another kernel than /netbsd or /bsd, loadable kernel mod-
ules can crash your system. Always boot in single user mode when you want to
run another kernel.

     Caveat: the  aperture driver only allows one access at a time (so
     that the system is in the same security state once X is launched).
     This means that if you run multiple servers on multiples VT, only the
     first one will have linear memory access.  Use 'option INSECURE' if
     you need more that one X server at a time.

7.3  MIT-SHM

NetBSD 1.0 and later supports System V shared memory. If XFree86 detects this
support in your kernel, it will support the MIT-SHM extension.

To add support for system V shared memory to your kernel add the lines:

      # System V-like IPC
      options         SYSVMSG
      options         SYSVSEM
      options         SYSVSHM

to your kernel config file.


8.  Rebuilding the XFree86 Distribution

The server link kit allow you to rebuild just the X server with a minimum
amount of disk space.  Just unpack it, make the appropriate changes to the
xf86site.def, type ``./mkmf'' and ``make'' to link the server.  See
/usr/X11R6/lib/Server/README for more info.

See INSTALL for instructions on unbundling and building the source distribu-
tion.

You should configure the distribution by editing xc/config/cf/host.def  before
compiling.  To compile the sources, invoke ``make World'' in the xc directory.

8.1  Console drivers

XFree86 3.3.3 has a configuration option to select the console drivers to use
in xf86site.def:

   o  if you're using pccons put:

           #define XFree86ConsoleDefines -DPCCONS_SUPPORT










README for XFree86 3.3.3 on NetBSD                                            7



   o if you're using pcvt put:

           #define XFree86ConsoleDefines -DPCVT_SUPPORT

   o if you're using syscons put:

           #define XFree86ConsoleDefines -DSYSCONS_SUPPORT

   o if you're running codrv put:

           #define XFree86ConsoleDefines -DCODRV_SUPPORT


If you don't define XFree86ConsoleDefines in xf86site.def the pccons and pcvt
drivers will be supported by default.

Syscons and codrv are not bundled with NetBSD. They are available by anonymous
FTP from a number of sites. They are not supported by the XFree86 binary dis-
tribution anymore.

8.2  pcvt_ioctl.h file:

XFree86's default configuration includes support for the PCVT console driver.
Unfortunately, NetBSD versions before 19980413 don't install the pcvt_ioctl.h
file in /usr/include/machine. If you want to build XFree86 with PCVT support,
execute the following command as root before starting make World:

     cp /usr/src/sys/arch/i386/isa/pcvt/pcvt_ioctl.h /usr/include/machine

If you don't have kernel sources, you can grab this file from ftp.netbsd.org or
one of its mirrors. If you're not running PCVT, you can remove -DPCVT_SUPPORT
from XFree86ConsoleDefines in xf86site.def too.

8.3  console.h and ioctl_pc.h files:

If you want to build a server supporting codrv and you don't already have the
corresponding header file ioctl_pc.h installed in /usr/include/machine, then
install the copy that is supplied in xc/programs/Xserver/hw/xfree86/etc.  If
you run NetBSD-current you probably want to install it in
/usr/src/sys/arch/i386/include too, so that it get reinstalled each time you
run make includes.

If you have installed the  codrv console driver, this file should be taken from
your installed version of the driver.

The console.h file for syscons isn't distributed with XFree86 anymore. You
should get it from the syscons distribution.

8.4  Support for shared libs under NetBSD 1.0 and later

By default XFree86 builds for NetBSD with shared libraries support. If you're
building on 0.9 or don't want shared libraries add the following line to
host.def:









README for XFree86 3.3.3 on NetBSD                                            8




     #define BuildBsdSharedLibs    NO

8.5  Building on other architectures

XFree86 3.3.3 also compiles on NetBSD/sparc. The Sun server patches from Dennis
Ferguson and Matthew Green have been integrated in xc/programs/Xserver/hw/sun.
Small modifications to xf86site.def are needed:

   o Set all variables defining the servers to build to NO. (The variables con-
     trolling the Sun servers to build Xsun24Server, XsunServer and Xsun-
     MonoServer are defined at the end of NetBSD.cf.)

   o Set ServerToInstall to the sun server of your choice. (Xsun or XsunMono).

   o Look at other applicable options in the INSTALL document.

Problems with this port should be reported to the port-sparc@NetBSD.Org mailing
list or directly to me matthieu@laas.fr rather than to the xfree86 mailing
list.


Note that the NetBSD project has now its own source tree, based on the XFree86
source tree, with some local modifications. You may want to start with this
tree to rebuild from sources.  The NetBSD xsrc source tree is available at:
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-current/xsrc/


9.  Building New X Clients

The easiest way to build a new client (X application) is to use xmkmf if an
Imakefile is included in the sources.  Type ``xmkmf -a'' to create the Make-
files, check the configuration if necessary and type ``make''.  Whenever you
install additional man pages you should update whatis.db by running ``make-
whatis /usr/X11R6/man''.

To avoid the ``Virtual memory exhausted'' message from cc while compiling,
increase the data and stack size limits (in csh type ``limit datasize 32M'' and
``limit stacksize 16M'').

Note: Starting with XFree86 2.1 and NetBSD 0.9A, the symbol __386BSD__ no
longer gets defined either by the compiler or via the X config files for *BSD
systems.  When porting clients to *BSD systems, make use of the symbol BSD for
code which is truly BSD-specific.  The value of the symbol can be used to dis-
tinguish different BSD releases.  For example, code specific to the Net-2 and
later releases can use:


     #if (BSD >= 199103)

To ensure that this symbol is correctly defined, include <sys/param.h> in the
source that requires it.  Note that the symbol CSRG_BASED is defined for *BSD
systems in XFree86 3.1.1 and later.  This should be used to protect the inclu-
sion of <sys/param.h>.








README for XFree86 3.3.3 on NetBSD                                            9



For code that really is specific to a particular i386 BSD port, use __FreeBSD__
for FreeBSD, __NetBSD__ for NetBSD, __OpenBSD__ for OpenBSD, __386BSD__ for
386BSD, and __bsdi__ for BSD/386.

Another note: If you get the message:


     ld.so: undefined symbol _XtCvtStringToFont

at run-time, you've stumbled on a semantic weakness of the NetBSD dynamic
linker. Applications that use libXmu also need libXt. If the client uses a
standard Imakefile, this dependency will probably by included in the Makefile
automagically -- you'll not see the problem. Otherwise, just add ``-lXt'' to
your library list in the Imakefile or Makefile and relink.
