DESCRIPTION
       mouse  is  an  Xorg  input  driver  for mice.  The driver supports most
       available mouse types and interfaces, though the	level of  support  for
       types of	mice depends on	the OS.

       The mouse driver	functions as a pointer input device. Multiple mice are
       supported by multiple instances of this driver.

SUPPORTED HARDWARE
       USB mouse
	      USB (Universal Serial Bus) ports are present on most modern com-
	      puters.  Several devices can be plugged into this	bus, including
	      mice and keyboards.  Support for USB mice	is platform specific.

       PS/2 mouse
	      The PS/2 mouse is	an intelligent device and may have  more  than
	      three  buttons  and a wheel or a roller.	The PS/2 mouse is usu-
	      ally compatible with the original	PS/2 mouse  from  IBM  immedi-
	      ately  after  power up.  The PS/2	mouse with additional features
	      requires a specialized initialization procedure to enable	 these
	      features.	  Without  proper initialization, it behaves as	though
	      it were an ordinary two or three button mouse.

       Serial mouse
	      There have been numerous serial mouse models from	 a  number  of
	      manufacturers.  Despite the wide range of	variations, there have
	      been relatively few  protocols  (data  format)  with  which  the
	      serial mouse talks to the	host computer.

	      The  modern serial mouse conforms	to the PnP COM device specifi-
	      cation so	that the host computer can  automatically  detect  the
	      mouse and	load an	appropriate driver.  This driver supports this
	      specification and	can detect popular PnP serial mouse models  on
	      most platforms.

       Bus mouse
	      The  bus	mouse  connects	 to  a	dedicated interface card in an
	      expansion	slot.  Some older video	cards, notably those from ATI,
	      and integrated I/O cards may also	have a bus mouse connector.

       The  interface  type  of	 the mouse can be determined by	looking	at the
       connector of the	mouse.	USB mice have a	 thin  rectangular  connector.
       PS/2 mice are equipped with a small, round DIN 6-pin connector.	Serial
       mouse have a D-Sub female 9- or 25-pin connector.  Bus mice have	either
       a D-Sub male 9-pin connector or a round DIN 9-pin connector.  Some mice
       come with adapters  with	 which	the  connector	can  be	 converted  to
       another.	  If you are to	use such an adapter, remember that the connec-
       tor at the very end of the mouse/adapter	pair is	what matters.

CONFIGURATION DETAILS
       Depending on the	X server version in use, input device options  may  be
       set  in	either a xorg.conf file, an xorg.conf.d	snippet	or in the con-
       figuration files	read by	the Hardware Abstraction Layer	(HAL)  daemon,
       hald(1).

       Please  refer to	xorg.conf(5) for general configuration details and for
       options that can	be used	with all input	drivers.   This	 section  only
       covers configuration details specific to	this driver.

       The  driver  can	auto-detect the	mouse type on some platforms.  On some
       platforms this is limited to plug and play serial mice, and on some the
       auto-detection  works  for  any	mouse that the OS's kernel driver sup-
       ports.  On others, it is	always necessary to specify the	mouse protocol
       in the config file.  The	README document	provided with this driver con-
       tains some detailed information about this.

       The following driver Options are	supported:

       Option "Protocol" "string"
	      Specify the mouse	protocol.  Valid protocol types	include:

		   Auto, Microsoft, MouseSystems, MMSeries,  Logitech,	Mouse-
		   Man,	 MMHitTab,  GlidePoint,	 IntelliMouse,	ThinkingMouse,
		   ValuMouseScroll, AceCad, PS/2, ImPS/2, ExplorerPS/2,	Think-
		   ingMousePS/2,    MouseManPlusPS/2,	GlidePointPS/2,	  Net-
		   MousePS/2, NetScrollPS/2, BusMouse, SysMouse, WSMouse, USB,
		   VUID, Xqueue.

	      Not  all	protocols  are supported on all	platforms.  The	"Auto"
	      protocol	specifies  that	 protocol  auto-detection  should   be
	      attempted.  The default protocol setting is platform-specific.

       Option "Device" "string"
	      Specifies	the device through which the mouse can be accessed.  A
	      common setting is	"/dev/mouse", which is often a	symbolic  link
	      to  the  real device.  This option is mandatory, and there is no
	      default setting. The driver may however attempt  to  probe  some
	      default  devices	if  this option	is missing.  Property: "Device
	      Node" (read-only).

       Option "Buttons"	"integer"
	      Specifies	the number of mouse buttons.  In cases where the  num-
	      ber  of buttons cannot be	auto-detected, the default value is 3.
	      The maximum number is 24.

       Option "Emulate3Buttons"	"boolean"
	      Enable/disable the emulation of the third	(middle) mouse	button
	      for mice which only have two physical buttons.  The third	button
	      is emulated by pressing both buttons  simultaneously.   Default:
	      on, until	a press	of a physical button 3 is detected.  Property:
	      "Mouse Middle Button Emulation"

       Option "Emulate3Timeout"	"integer"
	      Sets the timeout (in milliseconds) that the driver waits	before
	      deciding	if  two	 buttons where pressed "simultaneously"	when 3
	      button emulation is enabled.  Default:  50.    Property:	"Mouse
	      Middle Button Timeout"

       Option "ChordMiddle" "boolean"
	      Enable/disable handling of mice that send	left+right events when
	      the middle button	is used.  Default: off.

       Option "EmulateWheel" "boolean"
	      Enable/disable "wheel" emulation.	 Wheel emulation means emulat-
	      ing  button press/release	events when the	mouse is moved while a
	      specific real button is pressed.	Wheel button events (typically
	      buttons  4  and 5) are usually used for scrolling.  Wheel	emula-
	      tion is useful for getting wheel-like behaviour with trackballs.
	      It  can  also  be	 useful	for mice with 4	or more	buttons	but no
	      wheel.  See the description of the EmulateWheelButton,  Emulate-
	      WheelInertia,  XAxisMapping,  and	 YAxisMapping  options	below.
	      Default: off.

       Option "EmulateWheelButton" "integer"
	      Specifies	which button must be held down to enable wheel	emula-
	      tion  mode.  While this button is	down, X	and/or Y pointer move-
	      ment will	generate button	press/release events as	specified  for
	      the  XAxisMapping	 and  YAxisMapping  settings.  If set to 0, no
	      button is	required and any motion	of  the	 device	 is  converted
	      into wheel events.  Default: 4.

       Option "EmulateWheelInertia" "integer"
	      Specifies	 how far (in pixels) the pointer must move to generate
	      button press/release events in wheel emulation  mode.   Default:
	      10.

       Option "EmulateWheelTimeout" "integer"
	      Specifies	 the  time in milliseconds the EmulateWheelButton must
	      be pressed before	wheel emulation	is started.  If	 the  Emulate-
	      WheelButton is released before this timeout, the original	button
	      press/release event is sent.  Default: 200.

       Option "XAxisMapping" "N1 N2"
	      Specifies	which buttons are mapped to motion in the X  direction
	      in wheel emulation mode.	Button number N1 is mapped to the neg-
	      ative X axis motion and button number N2 is mapped to the	 posi-
	      tive X axis motion.  Default: no mapping.

       Option "YAxisMapping" "N1 N2"
	      Specifies	 which buttons are mapped to motion in the Y direction
	      in wheel emulation mode.	Button number N1 is mapped to the neg-
	      ative  Y axis motion and button number N2	is mapped to the posi-
	      tive Y axis motion.  Default: no mapping.

       Option "ZAxisMapping" "X"

       Option "ZAxisMapping" "Y"

       Option "ZAxisMapping" "N1 N2"

       Option "ZAxisMapping" "N1 N2 N3 N4"
	      Set the mapping for the Z	axis  (wheel)  motion  to  buttons  or
	      another  axis (X or Y).  Button number N1	is mapped to the nega-
	      tive Z axis motion and button number N2 is mapped	to  the	 posi-
	      tive  Z axis motion.  For	mice with two wheels, four button num-
	      bers can be specified, with the negative and positive motion  of
	      the  second  wheel  mapped respectively to buttons number	N3 and
	      N4.  Note	that the protocols for mice with one  and  two	wheels
	      can  be  different  and the driver may not be able to autodetect
	      it.  Default: "4 5".

       Option "ButtonMapping" "N1 N2 [...]"
	      Specifies	how physical mouse buttons are mapped to logical  but-
	      tons.   Physical button 1	is mapped to logical button N1,	physi-
	      cal button 2 to N2, and so forth.	 This enables the use of phys-
	      ical    buttons	 that	 are	obscured    by	 ZAxisMapping.
	      Default: "1 2 3 8	9 10 ...".

       Option "FlipXY" "boolean"
	      Enable/disable swapping the X and	Y axes.	  This	transformation
	      is applied after the InvX, InvY and AngleOffset transformations.
	      Default: off.

       Option "InvX" "boolean"
	      Invert the X axis.  Default: off.

       Option "InvY" "boolean"
	      Invert the Y axis.  Default: off.

       Option "AngleOffset" "integer"
	      Specify a	clockwise angular offset (in degrees) to apply to  the
	      pointer  motion.	 This  transformation  is  applied  before the
	      FlipXY, InvX and InvY transformations.  Default: 0.

       Option "SampleRate" "integer"
	      Sets the number of motion/button events the mouse	sends per sec-
	      ond.   Setting  this  is only supported for some mice, including
	      some Logitech  mice  and	some  PS/2  mice  on  some  platforms.
	      Default: whatever	the mouse is already set to.

       Option "Resolution" "integer"
	      Sets  the	 resolution of the device in counts per	inch.  Setting
	      this is only supported for some mice, including some  PS/2  mice
	      on  some	platforms.  Default: whatever the mouse	is already set
	      to.

       Option "Sensitivity" "float"
	      Mouse movements are multiplied by	this float before  being  pro-
	      cessed.  Use  this  mechanism to slow down high resolution mice.
	      Because values bigger than 1.0 will result in not	all pixels  on
	      the  screen being	accessible, you	should better use mouse	accel-
	      eration (see man xset) for  speeding  up	low  resolution	 mice.
	      Default: 1.0

       Option "DragLockButtons"	"L1 B2 L3 B4"
	      Sets "drag lock buttons" that simulate holding a button down, so
	      that low dexterity people	do not have to hold a button  down  at
	      the  same	time they move a mouse cursor. Button numbers occur in
	      pairs, with the lock button number occurring first, followed  by
	      the button number	that is	the target of the lock button.

       Option "DragLockButtons"	"M1"
	      Sets a "master drag lock button" that acts as a "Meta Key" indi-
	      cating that the next button pressed is to	be "drag locked".

       Option "ClearDTR" "boolean"
	      Enable/disable clearing the DTR line on the serial port used  by
	      the  mouse.   Some dual-protocol mice require the	DTR line to be
	      cleared to operate in the	non-default protocol.  This option  is
	      for  serial  mice	only and is handled by the X server.  Default:
	      off.

       Option "ClearRTS" "boolean"
	      Enable/disable clearing the RTS line on the serial port used  by
	      the  mouse.   Some dual-protocol mice require the	RTS line to be
	      cleared to operate in the	non-default protocol.  This option  is
	      for  serial  mice	only and is handled by the X server.  Default:
	      off.

       Option "BaudRate" "integer"
	      Set the baud rate	to use for communicating with a	serial	mouse.
	      This  option  should  rarely  be required	because	the default is
	      correct for almost all situations.  Valid	values	include:  300,
	      1200, 2400, 4800,	9600, 19200.  Default: 1200.

       There are some other options that may be	used to	control	various	param-
       eters for serial	port communication, but	they are not  documented  here
       because the driver sets them correctly for each mouse protocol type.
