DESCRIPTION

       synaptics  is  an  Xorg  input  driver for the touchpads from Synaptics
       Incorporated. Even though these touchpads (by default, operating  in  a
       compatibility  mode  emulating  a standard mouse) can be handled by the
       normal evdev  or  mouse  drivers,  this  driver  allows  more  advanced
       features of the touchpad to become available. Some benefits would be:

       ·   Movement with adjustable, non-linear acceleration and speed.

       ·   Button events through short touching of the touchpad.

       ·   Double-Button events through double short touching of the touchpad.

       ·   Dragging through short touching and holding down the finger on  the
           touchpad (tap-and-drag gesture).

       ·   Middle and right button events on the upper and lower corner of the
           touchpad.

       ·   Vertical scrolling (button four and five events) through moving the
           finger on the right side of the touchpad.

       ·   The up/down button sends button four/five events.

       ·   Horizontal  scrolling  (button six and seven events) through moving
           the finger on the lower side of the touchpad.

       ·   The  multi-buttons  send  button  four/five  events  for   vertical
           scrolling and button six/seven events for horizontal scrolling.

       ·   Adjustable finger detection.

       ·   Multifinger  taps: two finger for right button and three finger for
           middle button events.  (Needs hardware  support.   Not  all  models
           implement this feature.)

       ·   Pressure dependent motion speed.

       ·   Run-time  configuration  using  shared  memory.  This means you can
           change parameter settings without restarting the X server.

       Note that depending on the touchpad firmware, some  of  these  features
       might  be  available even without using the synaptics driver. Note also
       that some functions are not available on all touchpad  models,  because
       they  need  support  from  the touchpad hardware/firmware. (Multifinger
       taps for example.)

CONFIGURATION DETAILS

       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 following driver Options are supported:

       Option "Device" "string"
              This option specifies the device file in your  "/dev"  directory
              which  will  be used to access the physical device. Normally you
              should use something like "/dev/input/eventX", where X  is  some
              integer.

       Option "Protocol" "string"
              Specifies  which kernel driver will be used by this driver. This
              is  the  list  of  supported  drivers  and  their  default   use
              scenarios.

              auto-dev   automatic, default (recommend)
              event      Linux 2.6 kernel events

              Property: "Synaptics Button Scrolling"

       Option "UpDownScrollRepeat" "boolean"
              If   on,   and  the  up/down  buttons  are  used  for  scrolling
              (UpDownScrolling), these buttons will  send  auto-repeating  4/5
              events,   with   the   delay   between   repeats  determined  by
              ScrollButtonRepeat.   Property:  "Synaptics   Button   Scrolling
              Repeat"

       Option "LeftRightScrollRepeat" "boolean"
              If  on,  and  the  left/right  buttons  are  used  for scrolling
              (LeftRightScrolling), these buttons will send auto-repeating 6/7
              events,   with   the   delay   between   repeats  determined  by
              ScrollButtonRepeat.   Property:  "Synaptics   Button   Scrolling
              Repeat"

       Option "ScrollButtonRepeat" "integer"

              If off, a tap-and-drag gesture ends when you release the finger.
              If  on,  the  gesture  is active until you tap a second time, or
              until LockedDragTimeout  expires.  Property:  "Synaptics  Locked
              Drags"

       Option "LockedDragTimeout" "integer"
              This parameter specifies how long it takes (in milliseconds) for
              the LockedDrags mode to be automatically turned  off  after  the
              finger  is  released  from  the  touchpad.  Property: "Synaptics
              Locked Drags Timeout"

       Option "RTCornerButton" "integer"

              touchpads. Property: "Synaptics Circular Pad"

       Option "PalmDetect" "boolean"
              If  palm  detection  should  be  enabled.   Note  that this also
              requires hardware/firmware support from the touchpad.  Property:
              "Synaptics Palm Detection"

       Option "PalmMinWidth" "integer"
              Minimum  finger  width  at  which  touch  is  considered a palm.
              Property: "Synaptics Palm Dimensions"

       Option "PalmMinZ" "integer"

              Property: "Synaptics Palm Dimensions"

       Option "CoastingSpeed" "float"
              Coasting   threshold  scrolling  speed.   0  disables  coasting.
              Property: "Synaptics Coasting Speed"

       Option "SingleTapTimeout" "integer"
              Timeout after a tap to recognize it as a single  tap.  Property:
              "Synaptics Tap Durations"

       Option "GrabEventDevice" "boolean"
              If  GrabEventDevice  is  true,  the  driver  will grab the event
              device  for  exclusive  use  when  using  the  linux  2.6  event
              protocol.   When  using  other  protocols,  this  option  has no
              effect.  Grabbing the event device  means  that  no  other  user
              space or kernel space program sees the touchpad events.  This is
              desirable if the X config file includes  /dev/input/mice  as  an
              input  device,  but  is  undesirable  if you want to monitor the
              device from user space.  When changing this parameter  with  the
              synclient  program,  the  change  will not take effect until the
              synaptics  driver  is  disabled  and  reenabled.   This  can  be
              achieved  by switching to a text console and then switching back
              to X.

       Option "TapAndDragGesture" "boolean"
              Switch on/off the tap-and-drag  gesture.   This  gesture  is  an
              alternative  way  of  dragging.   It  is  performed  by  tapping
              (touching and releasing the finger),  then  touching  again  and
              moving  the  finger  on the touchpad.  The gesture is enabled by
              default and can be disabled  by  setting  the  TapAndDragGesture
              option to false. Property: "Synaptics Gestures"

       Option "VertResolution" "integer"
              Resolution  of  X  coordinates in units/millimeter. The value is
              used  together  with  HorizResolution  to   compensate   unequal
              vertical  and horizontal sensitivity. Setting VertResolution and
              HorizResolution equal  values  means  no  compensation.  Default
              value  is  read from the touchpad or set to 1 if value could not
              be read.  Property: "Synaptics Pad Resolution"

       Option "HorizResolution" "integer"
              Resolution of Y coordinates in units/millimeter.  The  value  is
              used together with VertResolution to compensate unequal vertical
              and   horizontal   sensitivity.   Setting   VertResolution   and
              HorizResolution  equal  values  means  no  compensation. Default
              value is read from the touchpad or set to 1 if value  could  not
              be read.  Property: "Synaptics Pad Resolution"

       The  LeftEdge, RightEdge, TopEdge and BottomEdge parameters are used to
       define the edge and corner areas of the touchpad.  The parameters split
       the touchpad area in 9 pieces, like this:

             |             |
             | LeftEdge    | RightEdge
       +-----+-------------+---+ Physical top edge
       | 1   |      2      | 3 |
       +-----+-------------+---+ TopEdge

       Coordinates to the left of LeftEdge are part of the left edge (areas 1,
       4 and 7), coordinates to the left of LeftEdge and above  TopEdge  (area
       1)  are  part  of  the  upper  left  corner,  etc.   A good way to find
       appropriate edge parameters is to enable the SHMConfig option  and  run
       "synclient  -m 1" to see the x/y coordinates corresponding to different
       positions on the touchpad.

       Option "AreaLeftEdge" "integer"
              Ignore movements, scrolling and tapping which take place left of
              this edge.  The option is disabled by default and can be enabled
              by setting the AreaLeftEdge option to any  integer  value  other
              than zero. Property: "Synaptics Area"

       Option "AreaRightEdge" "integer"
              Ignore  movements,  scrolling and tapping which take place right
              of this edge.  The option is disabled  by  default  and  can  be
              enabled by setting the AreaRightEdge option to any integer value
              other than zero. Property: "Synaptics Area"

       Option "AreaTopEdge" "integer"
              Ignore movements, scrolling and tapping which take  place  above
              this edge.  The option is disabled by default and can be enabled
              by setting the AreaTopEdge option to  any  integer  value  other
              than zero. Property: "Synaptics Area"

       Option "AreaBottomEdge" "integer"
              Ignore  movements,  scrolling and tapping which take place below
              this edge.  The option is disabled by default and can be enabled
              by  setting the AreaBottomEdge option to any integer value other
              than zero. Property: "Synaptics Area"

       Option "JumpyCursorThreshold" "integer"
              Set the threshold above which movement  events  are  ignored  on
              single-touch  touchpads.   The option is disabled by default and
              can be enabled by setting the JumpyCursorThreshold option to any
              integer value other than zero. Property: "Synaptics Jumpy Cursor
              Threshold"

       A tap event happens when the finger is touched and released in  a  time
       interval shorter than MaxTapTime, and the touch and release coordinates
       are less than MaxTapMove units apart.  A "touch" event happens when the
       Z  value goes above FingerHigh, and an "untouch" event happens when the
       Z value goes below FingerLow.

       The MaxDoubleTapTime parameter has the same function as the  MaxTapTime
       parameter,  but  for  the second, third, etc tap in a tap sequence.  If
       you can’t perform double clicks fast enough (for example, xmms  depends
       on  fast double clicks), try reducing this parameter.  If you can’t get
       word selection to work in xterm (ie  button  down,  button  up,  button
       down, move mouse), try increasing this parameter.

       The  ClickTime parameter controls the delay between the button down and
       button up X events generated in response to a tap event.   A  too  long
       value  can  cause undesirable autorepeat in scroll bars and a too small
       value means that visual feedback  from  the  gui  application  you  are
       interacting  with  is  harder  to  see.  For this parameter to have any
       effect, "FastTaps" has to be disabled.

       The MinSpeed, MaxSpeed and AccelFactor parameters control  the  pointer
       motion  speed.   The  speed  value defines the scaling between touchpad
       coordinates and  screen  coordinates.   When  moving  the  finger  very
       slowly,  the MinSpeed value is used, when moving very fast the MaxSpeed
       value is used.  When moving the finger at moderate  speed,  you  get  a
       pointer  motion  speed somewhere between MinSpeed and MaxSpeed.  If you
       don’t want any acceleration, set MinSpeed  and  MaxSpeed  to  the  same
       value.

       The MinSpeed, MaxSpeed and AccelFactor parameters don’t have any effect
       on scrolling speed.  Scrolling speed  is  determined  solely  from  the
       VertScrollDelta  and  HorizScrollDelta parameters.  To disable vertical
       or horizontal scrolling, set  VertScrollDelta  or  HorizScrollDelta  to
       zero.

       When  hitting  an  egde,  movement  can be automatically continued.  If
       EdgeMotionUseAlways is false, edge motion is only used  when  dragging.
       With EdgeMotionUseAlways set to true, it is also used for normal cursor
       movements.

       Edge motion speed is calculated by taking into account  the  amount  of
       pressure  applied  to  the  touchpad.   The sensitivity can be adjusted
       using  the  EdgeMotion  parameters.    If   the   pressure   is   below
       EdgeMotionMinZ,  EdgeMotionMinSpeed  is  used,  and  if the pressure is
       greater  than  EdgeMotionMaxZ,  EdgeMotionMaxSpeed  is  used.   For   a
       pressure  value between EdgeMotionMinZ and EdgeMotionMaxZ, the speed is
       increased linearly.

       When pressure motion is activated, the cursor motion speed  depends  on
       the  pressure exerted on the touchpad (the more pressure exerted on the
       touchpad, the faster the pointer).  More precisely the speed  is  first
       calculated according to MinSpeed, MaxSpeed and AccelFactor, and then is
       multiplied by a sensitivity factor.   The  sensitivity  factor  can  be
       adjusted using the PressureMotion parameters.  If the pressure is below
       PressureMotionMinZ,  PressureMotionMinFactor  is  used,  and   if   the
       pressure is greater than PressureMotionMaxZ, PressureMotionMaxFactor is
       used.  By default, PressureMotionMinZ and PressureMotionMaxZ are  equal
       to  EdgeMotionMinZ  and  EdgeMotionMaxZ.   For a pressure value between
       PressureMotionMinZ and  PressureMotionMaxZ,  the  factor  is  increased
       linearly.

       Since   most  synaptics  touchpad  models  don’t  have  a  button  that
       corresponds to the middle button on a mouse,  the  driver  can  emulate
       middle mouse button events.  If you press both the left and right mouse
       buttons at almost the same  time  (no  more  than  EmulateMidButtonTime
       milliseconds apart) the driver generates a middle mouse button event.

       Circular  scrolling  acts  like  a  scrolling  wheel  on  the touchpad.
       Scrolling is engaged when a drag starts in the given  CircScrollTrigger
       region,  which  can  be  all  edges, a particular side, or a particular
       corner.  Once scrolling is engaged, moving  your  finger  in  clockwise
       circles  around  the  center  of the touchpad will generate scroll down
       events and counter clockwise motion will  generate  scroll  up  events.
       Lifting  your  finger  will  disengage  circular  scrolling.  Use tight
       circles near the center of the pad for fast scrolling and large circles
       for  better  control.   When  used  together  with  vertical scrolling,
       hitting the upper or lower right corner  will  seamlessly  switch  over
       from vertical to circular scrolling.

       Coasting  is  enabled  by setting the CoastingSpeed parameter to a non-
       zero value.  Coasting comes in two flavors: conventional  (finger  off)
       coasting, and corner (finger on) coasting.

       Conventional   coasting  is  enabled  when  coasting  is  enabled,  and
       CornerCoasting is set to false.  When conventional coasting is enabled,
       horizontal/vertical scrolling can continue after the finger is released
       from the lower/right edge of the touchpad.   The  driver  computes  the
       scrolling  speed  corresponding  to the finger speed immediately before
       the finger leaves the touchpad.  If this scrolling speed is larger than
       the CoastingSpeed parameter (measured in scroll events per second), the
       scrolling will continue with the same speed in the same direction until
       the finger touches the touchpad again.

       Corner coasting is enabled when coasting is enabled, and CornerCoasting
       is set to true.  When corner coasting is enabled,  edge  scrolling  can
       continue as long as the finger stays in a corner.  Coasting begins when
       the finger enters the corner, and continues until the finger leaves the
       corner.   CornerCoasting takes precedence over the seamless switch from
       edge scrolling to circular scrolling.  That is,  if  CornerCoasting  is
       active,  scrolling  will  stop,  and circular scrolling will not start,
       when the finger leaves the corner.

       Trackstick emulation mode is entered when pressing the finger  hard  on
       the  touchpad.  The FingerPress parameter controls the minimum required
       finger pressure.  If the finger hasn’t moved more than MaxTapMove after
       MaxTapTime  has  elapsed,  trackstick  mode  is entered.  In this mode,
       moving the finger slightly in any direction gives a speed  vector  that
       moves  the  pointer.   The TrackstickSpeed parameter controls the ratio
       between pointer speed and finger movement distance.  Trackstick mode is
       exited  when  the  finger  pressure  drops  below FingerLow or when the
       finger is moved further than MaxTapMove away from the initial position.

DEVICE PROPERTIES

       Synaptics  1.0 and higher support input device properties if the driver
       is running on X server 1.6 or higher. On these driver versions,  Option
       "SHMConfig"  is  not  needed  to  enable  run-time  configuration.  The

       Synaptics Area
              The AreaLeftEdge, AreaRightEdge, AreaTopEdge and  AreaBottomEdge
              parameters  are  used  to define the edges of the active area of
              the touchpad. All movements, scrolling and  tapping  which  take
              place  outside  of  this  area will be ignored. This property is
              disabled by default.

              32 bit, 4 values,  left,  right,  top,  bottom.  0  disables  an
              element.

       Synaptics Capabilities
              This read-only property expresses the physical capability of the
              touchpad, most notably whether the  touchpad  hardware  supports
              multi-finger tapping and scrolling.

              8  bit (BOOL), 5 values (read-only), has left button, has middle

              suppress movements (which take place in 20 milliseconds or less)
              whose covered distance is greater than or equal to the threshold
              on single-touch touchpads. This property is disabled by default.

              32 bit, 1 value. 0 disables the property.

NOTES

       If either of Protocol "auto-dev" (default) or Protocol "event" is used,
       the  driver  initializes defaults based on the capabilities reported by
       the kernel driver. Acceleration, edges and resolution are based on  the
       dimensions  reported  by the kernel. If the kernel reports multi-finger
       detection, two-finger vertical scrolling is  enabled,  horizontal  two-
       finger  scrolling  is  disabled  and  edge scrolling is disabled. If no
       multi-finger capabilities are reported, edge scrolling is  enabled  for
       both horizontal and vertical scrolling.  Tapping is disabled by default
       for touchpads with one or more physical buttons.  To enable it you need
       to  map  tap actions to buttons. See the "TapButton1", "TapButton2" and
       "TapButton3" options.

       Button mapping for physical buttons is handled in the server.   If  the
       device  is  switched  to  left-handed (an in-server mapping of physical
       buttons 1, 2, 3 to the logical buttons 3,  2,  1,  respectively),  both
       physical   and   TapButtons  are  affected.  To  counteract  this,  the
       TapButtons  need  to  be  set  up  in  reverse   order   (TapButton1=3,
       TapButton2=1).

REMOVED OPTIONS

       The following options are no longer part of the driver configuration:

       Option "Repeater" "string"

       Option "HistorySize" "integer"

       Option "SpecialScrollAreaRight" "boolean"
