-
- 1. What and Where is XFree86?
-
- XFree86 is a port of X11R6.4 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 improve-
- ments as well as many bug fixes.
-
- See the Copyright Notice.
-
- The sources for XFree86 4.0 are available by anonymous ftp from:
-
- ftp://ftp.XFree86.org/pub/XFree86/4.0
-
- Binaries of XFree86 for LynxOS x86 are available from:
-
- ftp://ftp.XFree86.org/pub/XFree86/4.0/binaries/LynxOS
-
- A list of mirror sites is provided by ftp://ftp.XFree86.org/pub/XFree86/MIR-
- RORS
-
- The binaries on the FTP site were built on the latest released LynxOS version
- at the time XFree86 4.0 was released. In this case it is `LynxOS x86 3.0.1'.
- Because of changes made to the object format they don't run on LynxOS ver-
- sions earlier than 3.0.0.
-
- Building of this XFree86 version has never been tested on LynxOS versions
- earlier than 2.5.1.
-
- XFree86 4.0 supports LynxOS on the x86 and on the PowerPC platform. X servers
- are currently available only on the x86 platform. The X server may work with
- some PowerPC platforms supported by LynxOS though this has not (yet) been
- thoroughly tested.
-
- If you need binaries for other platforms than the one on the XFree86 FTP
- server or if you have comments or suggestions about this document contact me
- (<tmueller@sysgo.de>).
-
- 2. Installing the Binaries
-
- Please refer to the Installation Document for detailed installation instruc-
- tions.
-
- It may be necessary to increase the process stack limit in order to run
- XFree86 on your system. Edit /etc/startab and reboot your system to make the
- changes active before you begin the installation.
-
- Also, be sure to include /usr/X11R6/bin in your PATH environment variable.
-
- Refer to the next section Running XFree86 (section , page ) for further
- information on necessary configuration steps before running XFree86 on
- LynxOS.
-
- 2.1 Accessing XFree86 manual pages
-
- Include /usr/X11R6/man in the MANPATH environment variable or add the direc-
- tory /usr/X11R6/man to /usr/Lib/man.config
-
- 3. Running XFree86
-
- This section describes the changes to the LynxOS environment which may be
- necessary to successfully run XFree86.
-
- 3.1 System tuning
-
- 3.1.1 Tunable parameters
-
- To reasonably run XFree86 you may have to adjust a few system parameters.
-
- On LynxOS 2.5.x and 3.0.x include a line
-
- #define X_WINDOWS
-
- in /sys/lynx.os/uparam.h.
-
- 3.1.2 Adjustment for "nv" driver for NVidia graphics cards
-
- If you're using the "nv" driver (Riva 128, nVidia TNT, TNT2, GeForce), you
- will have to increase the value of the SMEMS parameter in
- /sys/lynx.os/uparam.h from 10 to 20.
-
- 3.1.3 Increase number of ptys
-
- You should also increase the number of ptys to be able run a couple more
- xterms. You may replace /sys/cfg/pty.cfg with /usr/X11R6/lib/X11/etc/pty.cfg.
-
- 3.1.4 MTRR device driver
-
- If you're using an Intel PentiumPRO or Pentium II (or higher) class CPU you
- might want to install the MTRR device driver. This driver enables the XFree86
- X server to manipulate the CPU memory type range registers which may improve
- performance on certain systems.
-
- To install the driver (on LynxOS x86 2.5.0 systems an higher) follow these
- steps:
-
- # cd /
- # bash /usr/X11R6/lib/X11/etc/MTRR-Lynx.shar
- # cd sys/drivers/mtrr
- # make install
-
- Then add a line
-
- I:../drivers/mtrr/mtrr.cfg
-
- to /sys/lynx.os/CONFIG.TBL and rebuild the kernel (see next section).
-
- 3.1.5 Kernel build
-
- If you plan to use a PS/2 mouse to the following sections before rebuilding
- the kernel, if not, you should rebuild the kernel now:
-
- # cd /sys/lynx.os
- # make install
- # reboot -N
-
- 3.2 Mouse support in XFree86
-
- XFree86 includes support for PnP mice (see also Mouse Support in XFree86).
- The current LynxOS TTY device driver doesn't allow the necessary manipulation
- of the RTS line and therefore the support for PnP mice has been disabled for
- LynxOS.
-
- 3.3 PS/2 mouse drivers
-
- LynxOS x86 comes with a PS/2 mouse driver. If it is not currently installed
- on your system install it with /usr/bin/Install.ps2mouse. Older versions of
- this driver contained code to translate the PS/2 mouse protocol to the format
- of a serial mouse, thus you'll have to specify "Microsoft" as the mouse pro-
- tocol format. The mouse driver contained in LynxOS x86 patchlevel 015 (and
- higher) does no longer perform the protocol translation an therefore can be
- defined as "PS/2" protocol format.
-
- 3.4 ATC console driver and VT switching
-
- Currently there is no support for virtual terminal switching once the server
- has started. Support for this feature may be added in future versions (it
- requires a patch to the vt100 LynxOS terminal driver).
-
- You will need a free console which the X server will use for keyboard input.
- You must disable login on at least one of the four virtual terminals in
- /etc/ttys, e.g. /dev/atc3:
-
- change
-
- /dev/atc3:1:default:vt100at:/bin/login
-
- to
-
- /dev/atc3:0:default:vt100at:/bin/login
- ^
-
- 3.5 X Server debug diagnostics output and other VT peculiarities
-
- Output made by the XFree86 X on its stdout or stderr will be lost after the
- server switches to graphics mode. The XFree86 4.0 server stores its output in
- /usr/adm/XFree86.n.log (where n is the screen number).
-
- When the X server is running output made to other consoles will be lost.
- After server shutdown the screen contents of other consoles may be inconsis-
- tent with what one would expect (i.e. random).
-
- 4. Compiling the XFree86 Distribution
-
- The next sections contain LynxOS specific notes with respect to the build
- process.
-
- 4.1 Disk space requirements
-
- Currently there is no support for shared libraries in the LynxOS XFree86
- port. A complete binary installation along with manual pages will require
- approximately 100 MBytes of disk space. To compile the system you will need
- at least 250 MBytes of free disk space.
-
- 4.2 Changes to system environment (LynxOS x86)
-
- Before compiling the XFree86 distribution you will have to make a few little
- adjustments to your system:
-
- o If not already installed on your system create a shell script named
- /lib/cpp as follows:
-
- #!/bin/sh
- /usr/lib/gcc-lib/i386-unknown-lynxos2.5/2.7-96q1/cpp \
- -traditional "$@"
-
- On other platforms than the x86 the paths for the compiler support pro-
- grams are different. You may use
-
- gcc -v
-
- to find out the correct path. Set the file mode of /lib/cpp with
-
- # chown root /lib/cpp
- # chmod 755 /lib/cpp
-
- o Modify /lib/liblynx.a. The X servers need the smem_create() system call
- to map the frame buffer into their address space. The system call is in
- liblynx library along with other Lynx proprietary calls which (unfortu-
- nately) overlap with calls in libc. To reduce confusion you should mod-
- ify liblynx as follows:
-
- # mv /lib/liblynx.a /lib/liblynx.a.ORG
- # mkdir /tmp/xx; cd /tmp/xx
- # ar xv /lib/liblynx.a.ORG
- # ar rv /lib/liblynx.a *smem*
- # ranlib /lib/liblynx.a
-
- 4.3 make World
-
- If you have the MTRR device driver installed, add a line
-
- #define HasMTRRSupport YES
-
- to the config/cf/host.def file.
-
- You may then issue a
-
- make World
-
- to compile XFree86. After a few hours (and hopefully a successful build of
- the XFree86 system) you can install the software using
-
- make install
-
- You must be logged in as super-user (root) when you invoke `make install'.
-
- On LynxOS x86 2.5.0 you may encounter problems with make in deeply nested
- subdirectories (eg core dumps, hangups). In this case update to GNU make ver-
- sion 3.75 or higher.
-
- 4.4 Installing XFree86 manual pages
-
- LynxOS uses cat-able manual pages, and because a doc preparation system is
- definitely not a vital component of a real-time operating system you must
- first install groff-1.09 (or newer).
-
- XFree86 manual pages may be installed using
-
- make install.man
-
- The index and whatis database for the XFree86 manual pages will be created
- automatically. If you already have a whatis database or index file in the
- destination directories you should perform a sort/uniq operation to remove
- duplicate entries:
-
- for i in 1 3 5
- do
- rm -f /tmp/tmpfile
- sort /usr/X11R6/man/cat$i/LIST$i | uniq > /tmp/tmpfile
- mv /tmp/tmpfile /usr/X11R6/man/cat$i/LIST$i
- done
- sort /usr/X11R6/man/whatis | uniq > /tmp/tmpfile
- mv /tmp/tmpfile /usr/X11R6/man/whatis
