1.  Requirements

Before you can either compile or execute a binary distribution of X11R6.8.1,
the following conditions must be met:

   o Ensure that you are running Release 5.0.4 or later. This is required
     because OSS646 is only supported on those platforms. There are no plans
     to support X11R6.8.1 on earlier releases of OpenServer.

   o Ensure that OSS646, the ``Execution Environment Update'' package is
     installed, if appropriate.  Check the release notes for that update to
     see whether or not your current operating system requires this update.
     At least version OSS646B is required.  If you are running SCO OpenServer
     Release 5.0.7, you must have Maintenance Pack 1 installed.

   o Ensure that the "Graphics, Web and X11 Libraries" package is installed.
     At least version 1.3.2Ag is required.  You should always install the
     latest possible version of this supplement that is valid for your oper-
     ating system release.  From time to time this release is bundled with
     Maintenance Packs, so if you are running 5.0.7 or later, the latest ver-
     sion may be in the latest Maintenance Pack.  Always check the release
     notes for GWXLIBS to see if your platform requires the update.  The lat-
     est version can always be found at the SCO FTP site
     <URL:ftp://ftp.sco.com/pub/openserver5/opensrc>.

   o To compile X11R6.8.1, you must use the SCO-supported version of the GNU
     C Compiler.  It is possible that Skunkware versions of the compiler will
     work too, but this has not been tested.  The ``GNU Development System''
     is available for all releases from (and including) SCO OpenServer
     Release 5.0.5.  It is provided with the operating system in all versions
     from Release 5.0.7, although you need to run ``custom'' to install it
     from the media.  You can always download the latest latest version of
     the GNU Development System from the SCO FTP site
     <URL:ftp://ftp.sco.com/pub/openserver5/opensrc>.

   o If you are not using OSR 5.0.7 or later, you need to get an updated con-
     sole driver.  See urlnam <URL:http://www.sco.com> for details on
     OpenServer supplements.  If you can't or don't want to upgrade your con-
     sole driver, X11R6.8.1 will still compile, but you may run into problems
     with some cards such as the Riva TNT and ATI Rage cards.  The problem
     with the console driver in 5.0.6A and earlier is that when the X server
     sets graphics mode, the driver does not set a status bit, so any text
     that is sent directly to /dev/console, such as kernel warning or notice
     messages when you access tape drives or NFS notices, will be sent to the
     console video memory.  This just happens to be slap bang in the middle
     of palette data for the Riva TNT, so you get color map corruption.  The
     updated console driver also has an improved mechanism for allocating
     video memory that X11R6.8.1 detects at compile time, and it will use it
     if it exists.  It is STRONGLY recommended that you get the console
     driver update.

2.  Compiling X11R6.8.1

Using the GNU Development System, compiling the distribution should be fairly
straightforward.  Before attempting to compile the system though, you should
make sure that you have met all of the requirements above.  To actually start
the compilation, perform the following steps:

   o Copy the unmodified xorgsite.def in xc/config/cf to host.def. Edit
     host.def and make any changes you think you need. The most useful
     options to change are HasTcl, HasTk, HasXdmAuth if you have the file
     WrapHelp.c and GccWarningOptions. Due to the nature of OpenServer's
     header files, the default options for this last setting are a bit
     aggressive, and I recommend you set this option to -Wpointer-arith.

   o Make sure that the official version of the GNU Development System is
     first in your PATH.  The official version lives in /usr/gnu/bin, and the
     Skunkware version (if any) lives in /usr/local/bin. You must ensure that
     /usr/gnu/bin appears first in your PATH.

   o Go to the top level of the source tree and execute the command CC=gcc
     make World BOOTSTRAPCFLAGS=-DSCO5 2>&1 | tee world.log.  This will do a
     full build, and send all of the build results to the file world.log.

   o If the build succeeded, install the new server by executing the command
     make install 2>&1 | tee install.log as root.  This will send the install
     results to the file install.log.

   o If you want to install the manual pages, execute the command make
     install.man 2>&1 | tee -a install.log as root.

3.  Before Running X11R6.8.1

The SCO xterm terminfo description is not compatible with the xterm in the R5
distribution.

To use a Bus/Keyboard or PS2 mouse you should configure the mouse drivers
using 'mkdev mouse'.  You may then use the OsMouse option in your xorg.conf
to specify that X should use the SCO mouse drivers.  To do this, set the Pro-
tocol to "OsMouse" in the Pointer section of your xorg.conf file.  You can
also use "OsMouse" for your serial mouse, especially if you are having trou-
ble getting your mouse to work using the X mouse drivers.

4.  Switching Consoles

X11R6.8.1 uses similar console switching keys as the SCO R4 and R5 servers.
That is, Ctrl-PrntScr takes you to the next console along from the one X is
running on.  If this is the last console it will take you to console 1. Ctrl-
Alt-FXX, where XX is a function key between F1 and F12 will switch you to the
console number assigned to that function key. F1 corresponds to tty01 (or
console 1), F2 corresponds to tty02 (or console 2) etc.

Unlike the SCO X server, the "kill me now" key is Alt+Ctrl+Backspace.  This
does not ask for confirmation, it simply kills the X server as immediately as
possible.  Use with extreme caution.  This may cause applications to termi-
nate in an unpredictable way.  You can set the DontZap option in the Server-
Flags section of your XF86Config file to disable this.

5.  Setting up Man Pages

After compiling the tree, or after installing the binary distribution you can
get man to recognise the Xorg man pages by adding /usr/X11R6/man to the MAN-
PATH in /etc/default/man. The line should look similar to:

         MANPATH=/usr/man:/usr/gnu/man:/usr/X11R6/man:/usr/local/man

This allows all users to view the X man pages.  You may change your own MAN-
PATH environment variable if you do not want everyone to access the man
pages.

By default the man pages are compressed using ``compress'' to conserve space.
If you do not want to compress the man pages change CompressManPages to NO in
your ``host.def'' file.  Those using the binary distribution can use ``uncom-
press'' to uncompress the man pages.  Binary distributions contain pre-for-
matted versions of all man pages.  If you are compiling the server yourself,
you need to have the GNU Tools package installed to get groff, the GNU nroff
replacement, to format the man pages.  Use the manroff script to format the
manual pages yourself.

6.  Using SCO binaries/servers.

X11R6.8.1 will accept connections from SCO binaries (R3 upwards) and the SCO
R5 server will also accept connections from X11R6.8.1 binaries. This means
you may mix and match the two if you have ODT.  For example you may still use
the Panning Motif window manager (pmwm) if you prefer.
