DESCRIPTION
     mouse  is an XLibre input driver for mice.  The driver supports most avail-
     able 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  comput-
	    ers.   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 usually compati-
	    ble with the original PS/2 mouse from IBM  immediately  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  manu-
	    facturers.	 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 specification
	    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  inte-
	    grated I/O cards may also have a bus mouse connector.

     The interface type of the mouse can be determined by looking at the connec-
     tor  of  the  mouse.  USB mice have a thin rectangular connector, which may
     have rounded corners.  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 connec-
     tor.  Some mice come with adapters with which the	connector  can	be  con-
     verted  to  another.   If you are to use such an adapter, remember that the
     connector 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 configuration
     files read by the Hardware Abstraction Layer (HAL) daemon, hald(1).

     Please  refer to xorg.conf(5) for general configuration details and for op-
     tions 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 plat-
     forms  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  supports.   On
     others,  it is always necessary to specify the mouse protocol in the config
     file.  The README document provided with this driver contains 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,  MouseMan,
		 MMHitTab,  GlidePoint,  IntelliMouse,	ThinkingMouse, ValuMous-
		 eScroll, AceCad, PS/2, ImPS/2, ExplorerPS/2, ThinkingMousePS/2,
		 MouseManPlusPS/2, GlidePointPS/2, NetMousePS/2,  NetScrollPS/2,
		 BusMouse, SysMouse, WSMouse, VUID.

	    Not all protocols are supported on all platforms.  The "Auto" proto-
	    col 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  de-
	    vices  if  this  option  is missing.  Property: "Device Node" (read-
	    only).

     Option "Buttons" "integer"
	    Specifies the number of mouse buttons.  In cases where the number of
	    buttons cannot be auto-detected, the default value is 3.  The  maxi-
	    mum 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 emu-
	    lated 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 de-
	    ciding 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  emulating
	    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  emulation  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  de-
	    scription  of the EmulateWheelButton, EmulateWheelInertia, XAxisMap-
	    ping, and YAxisMapping options below.  Default: off.

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

     Option "EmulateWheelInertia" "integer"
	    Specifies how far (in pixels) the pointer must move to generate but-
	    ton 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	EmulateWheelBut-
	    ton  is  released before this timeout, the original button press/re-
	    lease 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 negative X
	    axis motion and button number N2 is mapped to the  positive  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 negative  Y
	    axis  motion  and  button number N2 is mapped to the positive 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 negative Z axis
	    motion and button number N2 is mapped to the positive Z axis motion.
	    For mice with two wheels, four button numbers can be specified, with
	    the negative and positive motion of the second wheel mapped  respec-
	    tively  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	buttons.
	    Physical  button 1 is mapped to logical button N1, physical button 2
	    to N2, and so forth.  This enables the use of physical 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.   De-
	    fault: 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 second.
	    Setting this is only supported for some mice,  including  some  Log-
	    itech  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 processed.
	    Use this mechanism to slow down high resolution mice.  Because  val-
	    ues  bigger than 1.0 will result in not all pixels on the screen be-
	    ing accessible, you should instead use mouse acceleration  (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" indicat-
	    ing 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 parameters
     for serial port communication, but they are not documented here because the
     driver sets them correctly for each mouse protocol type.
