NAME
       Xhp - cfb-based X window system server for Hewlett-Packard
       workstations

SYNOPSIS
       This cfb-based X server implementation is  contributed  by
       Hewlett-Packard as a sample implementation for HP worksta
       tions.  Its performance on HP workstations will	be  infe
       rior  to	 the  product  X  servers available from Hewlett-
       Packard.	 Not all graphics display devices available  from
       Hewlett-Packard are supported by this implementation.


SUPPORTED GRAPHICS DEVICES
       Please  refer  to the HP catalog or to the apropriate data
       sheets for the displays.	 The data  that	 follows  relates
       the  use of the product names with their official HP prod
       uct numbers.

       The following graphics display devices  are  supported  by
       this implementation:


       HPA4070A
	      This   graphics  device,	known  as  "HCRX",  is	a
	      1280x1024 color device that has 8 planes.

       HPA4071A
	      This graphics  device,  known  as	 "HCRX24",  is	a
	      1280x1024	 color	device that has 24 planes.  It is
	      optionally available with a  hardware  accelerator,
	      in which case the product number is HPA4071A_Z.

       HPA1659A
	      This   graphics	device,	 known	as  "CRX",  is	a
	      1280x1024 color device that has 8 planes.

       HPA1439A
	      This  graphics  device,  known  as  "CRX24",  is	a
	      1280x1024	 color	device that has 24 planes.  It is
	      optionally available with a hardware accelerator.

       HPA1924A
	      This graphics device, known as "GRX" is a 1280x1024
	      grayscale device that has 8 planes.

       HPA2269A
	      This  graphics  device,  known  as  "Dual CRX" is a
	      1280x1024 color  device  that  has  8  planes.   It
	      implements  support  for	two  displays on a single
	      graphics card.

       HP710C This graphics device is the internal graphics  sup
	      port  optionally	available  on the HP9000s710 SPU.

	      It supports 1280x1024  color  displays  and  has	8
	      planes.

       HP710G This  graphics device is the internal graphics sup
	      port optionally available on  the	 HP9000s710  SPU.
	      It  supports 1280x1024 grayscale displays and has 8
	      planes.

       HP710L This graphics device is the internal graphics  sup
	      port  optionally	available  on the HP9000s710 SPU.
	      It supports  1024x768  color  displays  and  has	8
	      planes.

       HP712  This  graphics device is the internal graphics sup
	      port available on the HP9000s712 SPU.  It	 supports
	      640x480,	1024x768  or 1280x1024 color displays and
	      has 8 planes.


MULTIPLE SCREEN SUPPORT
       This Xhp X11  sample  server  supports  multiple	 physical
       screens	connected to a single X server.	 To use this fea
       ture, you must have an SPU that allows the installation of
       a   second   graphics   display	card.	The  file  $(LIB
       DIR)/X*screens is read by  the  X11  server  to	determine
       information  about  the	system screen configuration.  You
       must modify this file to add information	 for  the  second
       graphics display.

       $(LIBDIR) is /usr/X11R6/lib/X11 by default.

       For a complete description of the X*screens file, refer to
       the HP-UX manuals, or view the sample file in $(LIBDIR).

24 PLANE SUPPORT FOR HCRX24 AND CRX24
       This Xhp X11 sample server  supports  two  modes	 for  the
       HCRX24  and CRX24 display hardware:  8 plane and 24 plane,
       with 8 plane being the default.	To run the server  in  24
       plane  mode,  you  must	add  a	depth  parameter  to  the
       X*screens file.	For example:

       /dev/crt	 depth 24


       In depth 24 mode, the default visual type is  DirectColor.


KEYMAP FILE
       This Xhp server loads a keymap that is appropriate for the
       attached keyboard from the XHPKeymaps file, which  resides
       in  $(LIBDIR).  The XHPKeymaps file supplied with this Xhp
       server is a minimal file that supports US English, French,
       Spanish,	 German, and Japanese JIS keyboards.  If you have
       some other keyboard, the appropriate  keymap  may  not  be

       contained  in  the  XHPKeymaps file.  In this case, if you
       have access to the Hewlett-Packard product X  server,  you
       can     copy	its	keymap	   file	    (found     in
       /usr/lib/X11/XHPKeymaps) to $(LIBDIR).

FAST SCROLLING OPTION
       Since scrolling speed is especially slow	 on  this  server
       compared	 to  HP's  product  server, we have supplied fast
       scrolling support, using a .o to	 link  into  the  server.
       Using HP's fast scrolling is optional.  To enable the fast
       scrolling, set the token "HPFastScrolling" to TRUE in  the
       config/hp.cf  file.   If you want to use the CFB scrolling
       module, simply remove the define in  config/hp.cf,  remake
       the Makefiles, and recompile.
