Touchpad multi-gesture

[cristian_c]

Ciao, sul mio computer è montato questo tipo di touchpad 

Sapete quale tool occorre utilizzare per gestire tutte le funzioni del touchpad?  ???

[cristian_c]

Mi è stata segnalata questa pagina wiki: https://wiki.kubuntu.org/Multitouch/GettingStarted/Natty, la quale rimanda a quest'altra: https://wiki.kubuntu.org/Multitouch/Ginn 

Però non ho capito dove va inserito il codice presente nel paragrafo 'Unity Gestures with Ginn'  ::)

Voi avete un'idea di come si possa fare? 

[cristian_c]

Faccio riferimento a questa pagina del wiki internazionale (che secondo me è sempre identica a quella indicata precedentemente  :-[ ): https://wiki.ubuntu.com/Multitouch/Ginn 

Ho trovato il file associato alle porzioni di codice, relative al paragrafo della guida in questione precedentemente menzionato, che si chiama wishes.xml e si trova in /etc/ginn 

Quando viene aperto il file in questione, esso ha al suo interno il seguente contenuto:

non la trovo  :-[

A questo punto come faccio ad abilitare tutti i gesture tipici del touchpad in questione? 

[cristian_c]

Mi è stato suggerito di utilizzare synaptics per attivare i gesture del touchpad, consultando prima il man di synaptics  (yes)

Il contenuto del man è il seguente:

Codice: Seleziona tutto

SYNAPTICS(4)                                                      SYNAPTICS(4)



NAME
       synaptics - touchpad input driver

SYNOPSIS
       Section "InputDevice"
         Identifier "devname"
         Driver "synaptics"
         Option "Device"   "devpath"
         Option "Path"     "path"
         ...
       EndSection

DESCRIPTION
       synaptics is an Xorg input driver for touchpads.  Even though touchpads
       can be handled by the normal evdev or mouse drivers, this driver allows
       more  advanced features of the touchpad to become available. Some bene‐
       fits 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.)

       The name "synaptics" is historical and the driver  still  provides  the
       synaptics  protocol  parsing  code.  Under Linux however, the hardware-
       specifics are handled by the kernel and this driver will work  for  any
       touchpad that has a working kernel driver.


CONFIGURATION OPTIONS
       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 scenar‐
              ios.

              auto-dev   automatic, default (recommend)
              event      Linux 2.6 kernel events
              psaux      raw device access (Linux 2.4)
              psm        FreeBSD psm driver

       Option "SHMConfig" "boolean"
              Switch on/off shared memory for run-time debugging. This  option
              does not have an effect on run-time configuration anymore and is
              only useful for hardware event debugging.

       Option "LeftEdge" "integer"
              X coordinate for left edge. Property: "Synaptics Edges"

              as a touch. Property: "Synaptics Finger"

       Option "FingerPress" "integer"
              When finger pressure goes above this value, the driver counts it
              as  a  press.   Currently  a  press is equivalent to putting the
              touchpad in trackstick emulation mode. Property: "Synaptics Fin‐
              ger"

              touchpads  with  physical  scroll buttons.  Property: "Synaptics
              Button Scrolling"

       Option "LeftRightScrolling" "boolean"
              If on, the left/right buttons generate button  6/7  events.   If

              with the delay between repeats determined by ScrollButtonRepeat.
              This option is only available for touchpads with physical scroll
              buttons.  Property: "Synaptics Button Scrolling Repeat"

       Option "LeftRightScrollRepeat" "boolean"
              If  on, and the left/right buttons are used for scrolling (Left‐
              RightScrolling), these  buttons  will  send  auto-repeating  6/7
              events,  with the delay between repeats determined by ScrollBut‐
              tonRepeat.  This option is only  available  for  touchpads  with
              physical  scroll buttons.  Property: "Synaptics Button Scrolling
              Repeat"

       Option "ScrollButtonRepeat" "integer"
              The number of milliseconds between repeats of button events  4-7
              from the up/down/left/right scroll buttons.  This option is only

              "Synaptics Button Scrolling Time"

       Option "EmulateMidButtonTime" "integer"
              Maximum  time  (in  milliseconds)  for  middle button emulation.
              Property: "Synaptics Middle Button Timeout"

       Option "EmulateTwoFingerMinZ" "integer"
              For touchpads not capable of detecting multiple fingers but  are
              capable  of detecting finger pressure and width, this sets the Z
              pressure threshold.  When both Z pressure and W width thresholds
              are  crossed, a two finger press will be emulated. This defaults
              to a value that disables emulation on touchpads with  real  two-
              finger  detection and defaults to a value that enables emulation
              on remaining touchpads that support pressure and width  support.
              Property: "Synaptics Two-Finger Pressure"

       Option "EmulateTwoFingerMinW" "integer"
              For  touchpads not capable of detecting multiple fingers but are
              capable of detecting finger width and pressure, this sets the  W
              width  threshold.   When  both W width and Z pressure thresholds
              are crossed, a two finger press will be emulated.  This  feature
              works  best with (PalmDetect) off. Property: "Synaptics Two-Fin‐
              ger Width"

              Property: "Synaptics Palm Dimensions"

       Option "CoastingSpeed" "float"
              Your  finger  needs  to  produce this many scrolls per second in
              order to start coasting.  The default is 20 which should prevent
              you  from  starting coasting unintentionally.  0 disables coast‐
              ing. Property: "Synaptics Coasting Speed"

              Default is 50.  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 proto‐
              col.  When using other protocols, this  option  has  no  effect.
              Grabbing the event device means that no other user space or ker‐
              nel 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 syn‐
              client program, the change will not take effect until the synap‐
              tics  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 (touch‐
              ing 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  verti‐
              cal  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 HorizRes‐
              olution  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 "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. If supported by the server (version 1.9  and  later),
              the  edge  may be specified in percent of the total width of the
              touchpad. 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.  If  supported by the server (version 1.9 and
              later), the edge may be specified in percent of the total  width
              of the touchpad. 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. If supported by the server (version 1.9  and  later),
              the  edge may be specified in percent of the total height of the
              touchpad. 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.  If supported by the server (version 1.9 and later),
              the edge may be specified in percent of the total height of  the
              touchpad. Property: "Synaptics Area"


CONFIGURATION DETAILS
   Area handling
       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
       │     │             │   │
       │ 4   │      5      │ 6 │
       │     │             │   │
       └─────└─────────────└───┘ BottomEdge
       │ 7   │      8      │ 9 │
       └─────└─────────────└───┘ Physical bottom edge
       │Physical left edge     │ Physical right edge

       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 SHMCon‐
       fig option and run "synclient -m 1" to see the x/y  coordinates  corre‐
       sponding to different positions on the touchpad.

       The  perceived  physical  edges  may be adjusted with the AreaLeftEdge,
       AreaRightEdge, AreaTopEdge, and AreaBottomEdge options. If these values
       are  set to something other than the physical edges, input in the space
       between the area edge and the respective physical edge is ignored. Note
       that this reduces the available space on the touchpad.

   Tapping
       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.

       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"

       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.

   Acceleration
       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 EdgeMotion‐
       MinZ, 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  lin‐
       early.

       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 pres‐
       sure 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 lin‐
       early.

   Middle button emulation
       Since most synaptics touchpad models don't have a  button  that  corre‐
       sponds  to  the middle button on a mouse, the driver can emulate middle
       mouse button events.  If you press both the left and right  mouse  but‐
       tons  at  almost  the same time (no more than EmulateMidButtonTime mil‐
       liseconds apart) the driver generates a middle mouse button event.

   Circular scrolling
       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 cor‐
       ner.   Once  scrolling is engaged, moving your finger in clockwise cir‐
       cles 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 cir‐
       cular scrolling.


   Coasting
       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  Corner‐
       Coasting is set to false.  When conventional coasting is enabled, hori‐
       zontal/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 mode
       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, mov‐
       ing  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  fin‐
       ger is moved further than MaxTapMove away from the initial position.

              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  ele‐
              ment.


       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), 7 values (read-only), has left button, has middle
              button, has right  button,  two-finger  detection,  three-finger
              detection, pressure detection, and finger/palm width detection.

              units/millimeter.


       Synaptics Jumpy Cursor Threshold
              The Synaptics Jumpy Cursor Threshold parameter is used  to  sup‐
              press  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  TapBut‐
       tons need to be set up in reverse order (TapButton1=3, TapButton2=1).


REMOVED OPTIONS

che ho controllato dall'inizio alla fine, ma ancora non ho capito qual'è il legame con il file wishes.xml  ::)

Avete un'idea di quale sia? 

[cristian_c]

Ho dato una lettura a questa guida: https://help.ubuntu.com/community/SynapticsTouchpad, ma non ho capito come possa aiutarmi  ::)

Avete qualche idea?  ???

Prova toucheeg, avevo letto una recensione sul programma e sembra funzionare bene.

Dai quanto hai segnalato pare che sia bello. Appena mi trovo sul notebook lo provo. Che bello, non lo conoscevo, grazie!
P.S. Però io non lo trovavo perché avevi scritto il nome in modo non corretto  :-[

[cristian_c]

Ho seguito le indicazioni presenti nel sito del programma su google code e ho installato il programma.
Però non sono riuscito a trovarlo da nessuna parte, in nessun meù, ho provato anche in Menù principale al fine di aggiungerlo ma non vi era traccia.
Allora l'ho lanciato da terminale ma si pianta (ho aspettato una vita) 
C'è una procedura specifica per utilizzarlo?  ???

per installarlo basta un apt-get install dato che e' presente nei repo di Oneric,
Per configurarlo l'unica maniera sembra essere quella di andare in .config/touchegg/touchegg.conf e modificare a mano
Ho provato a mettere la gui di natty ma crasha in continuazione ed inoltre legge un config in posizione diversa
Per farlo partire mettilo nei programmi all'avvio, anche se la finestra di teminale ti fa vedere quello che il programma sta recependo dal touchpad
Ancora non l'ho sperimentato a fondo ma sembra funzionare

ma se Oneiric non è neanche uscito ufficialmente...  (rotfl)

Io più che altro non ho capito come far apparire l'interfaccia grafica che si vede nella guida...  ::)

Hai ragione scusa, davo per scontato che usavi la 11.10, ( io la uso dalla seconda alpha)
Cmq per Natty ti rimando alla pagina :

http://code.google.com/p/touchegg/wiki/Downloads?tm=2

Io li ho trovato pure il deb della gui anche se e' una versione precedente.
Con la gui ( Che appare nelle applicazioni) puoi configurare le gesture che vuoi

che tra l'altro è vietato chiedere supporto nelle sezioni tecniche per questa release (almeno fino alla sua uscita ufficiale)

guarda che quello l'avevo già fatto  Però non ho trovato niente nelle Applicazioni 

[mrko27]

Boh,molto strano. Io ieri ho provato la gui e funzionava ( l'applicazione era presente )
L'unico motivo x cui l'ho tolta e' che crashava ( era x la ver 0.3)

Ma quando lanci touchegg da terminale funziona?

No, perché si pianta, io non vedo nessuna interfaccia grafica  ::)

[cristian_c]

Ho installato la versione 0.3 di touchegg e touchegg-gui, e fatto questo l'applicazione è apparsa nel menù Preferenze  (yes)

A parte che l'interfaccia grafica è un po' diversa da quella delle immagini e del video presenti su lffl, il problema maggiore è che non riesco a far funzionare i singoli gesti.
Mi spiego: per non fare confusione ho lasciato nella lista soltanto il gesto di interesse per provarlo singolarmente. Che io prema Apply o Accept, il risultato è che funziona tutto molto male o non funziona affatto. Ad esempio ho testato il pitch e riesco a farlo funzionare un po' ma è molto macchinoso e fallace. Mentre invece per quanto riguarda ad esempio il drag con tre dita per muovere le finestre non funziona affatto  :-\

Che procedura devo eseguire per testare al meglio i gesti? Hai qualche idea?  ???

Io sto provando la versione per la 11.10, e anche qui noto dei malfunzionamenti. La gui non c'e' e quindi devo intervenire sul file di config manualmente. Il problema maggiore e' che non c'e' la sicurezza che il comando parta cosi' come programmato.

Continuo a cercare una soluzione.

A qualcuno funziona bene :

[cristian_c]

Ho seguito le indicazioni scritte qui: http://www.ubuntu-linux.it/touchegg-gesture-multitouch-su-linux/, disinstallando la versione 0.3 e scaricando i due pacchetti della versione 0.2  (yes)

Però ancora non riesco a far funzionare i gesti: come posso fare?
