+Native support for HID input from the linux kernel
+==================================================
+
+Support starts from 2.6.32-ubuntu, or 2.6.34.
+
+To configure HIDInput, add this to your configuration::
+
+    [input]
+    # devicename = hidinput,/dev/input/eventXX
+    # example with Stantum MTP4.3" screen
+    stantum = hidinput,/dev/input/event2
+
+.. note::
+    You must have read access to the input event.
+
+You can use a custom range for the X, Y and pressure values.
+For some drivers, the range reported is invalid.
+To fix that, you can add these options to the argument line:
+
+* invert_x : 1 to invert X axis
+* invert_y : 1 to invert Y axis
+* min_position_x : X relative minimum
+* max_position_x : X relative maximum
+* min_position_y : Y relative minimum
+* max_position_y : Y relative maximum
+* min_abs_x : X absolute minimum
+* min_abs_y : Y absolute minimum
+* max_abs_x : X absolute maximum
+* max_abs_y : Y absolute maximum
+* min_pressure : pressure minimum
+* max_pressure : pressure maximum
+* rotation : rotate the input coordinate (0, 90, 180, 270)
+
+For example, on the Asus T101M, the touchscreen reports a range from 0-4095 for
+the X and Y values, but the real values are in a range from 0-32768. To correct
+this, you can add the following to the configuration::
+
+    [input]
+    t101m = hidinput,/dev/input/event7,max_position_x=32768,\
+max_position_y=32768
+
+.. versionadded:: 1.9.1
+
+    `rotation` configuration token added.

+Native support of Wacom tablet from linuxwacom driver

+    pen = linuxwacom,/dev/input/event2,mode=pen
+    finger = linuxwacom,/dev/input/event3,mode=touch
+
+.. note::

+
+You can use a custom range for the X, Y and pressure values.
+On some drivers, the range reported is invalid.
+To fix that, you can add these options to the argument line:
+
+* invert_x : 1 to invert X axis
+* invert_y : 1 to invert Y axis
+* min_position_x : X minimum
+* max_position_x : X maximum
+* min_position_y : Y minimum

+Mouse provider implementation
+=============================
+
+On linux systems, the mouse provider can be annoying when used with another
+multitouch provider (hidinput or mtdev). The Mouse can conflict with them: a
+single touch can generate one event from the mouse provider and another
+from the multitouch provider.
+
+To avoid this behavior, you can activate the "disable_on_activity" token in
+the mouse configuration. Then, if any touches are created by another
+provider, the mouse event will be discarded. Add this to your configuration::
+
+    [input]
+    mouse = mouse,disable_on_activity
+
+Using multitouch interaction with the mouse
+-------------------------------------------
+
+.. versionadded:: 1.3.0
+
+By default, the middle and right mouse buttons, as well as a combination of
+ctrl + left mouse button are used for multitouch emulation.
+If you want to use them for other purposes, you can disable this behavior by
+activating the "disable_multitouch" token::
+
+   [input]
+   mouse = mouse,disable_multitouch
+
+.. versionchanged:: 1.9.0
+
+You can now selectively control whether a click initiated as described above
+will emulate multi-touch. If the touch has been initiated in the above manner
+(e.g. right mouse button), a `multitouch_sim` value will be added to the
+touch's profile, and a `multitouch_sim` property will be added to the touch.
+By default, `multitouch_sim` is True and multitouch will be emulated for that
+touch. If, however, `multitouch_on_demand` is added to the config::
+
+   [input]
+   mouse = mouse,multitouch_on_demand
+
+then `multitouch_sim` defaults to `False`. In that case, if `multitouch_sim`
+is set to True before the mouse is released (e.g. in on_touch_down/move), the
+touch will simulate a multi-touch event. For example::
+
+    if 'multitouch_sim' in touch.profile:
+        touch.multitouch_sim = True
+
+.. versionchanged:: 2.1.0
+
+Provider dispatches hover events by listening to properties/events in
+:class:`~kivy.core.window.Window`. Dispatching can be disabled by setting
+:attr:`MouseMotionEventProvider.disable_hover` to ``True`` or by adding
+`disable_hover` in the config::
+
+    [input]
+    mouse = mouse,disable_hover
+
+It's also possible to enable/disable hover events at runtime with
+:attr:`MouseMotionEventProvider.disable_hover` property.
+
+Following is a list of the supported values for the
+:attr:`~kivy.input.motionevent.MotionEvent.profile` property list.
+
+================ ==========================================================
+Profile value    Description
+---------------- ----------------------------------------------------------
+button           Mouse button (one of `left`, `right`, `middle`, `scrollup`
+                 or `scrolldown`). Accessed via the 'button' property.
+pos              2D position. Also reflected in the
+                 :attr:`~kivy.input.motionevent.MotionEvent.x`,
+                 :attr:`~kivy.input.motionevent.MotionEvent.y`
+                 and :attr:`~kivy.input.motionevent.MotionEvent.pos`
+                 properties.
+multitouch_sim   Specifies whether multitouch is simulated or not. Accessed
+                 via the 'multitouch_sim' property.

+Native support for Multitouch devices on Linux, using libmtdev.
+===============================================================
+
+The Mtdev project is a part of the Ubuntu Maverick multitouch architecture.
+You can read more on http://wiki.ubuntu.com/Multitouch
+
+To configure MTDev, it's preferable to use probesysfs providers.
+Check :py:class:`~kivy.input.providers.probesysfs` for more information.
+
+Otherwise, add this to your configuration::
+
+    [input]
+    # devicename = hidinput,/dev/input/eventXX
+    acert230h = mtdev,/dev/input/event2
+
+.. note::
+    You must have read access to the input event.
+
+You can use a custom range for the X, Y and pressure values.
+On some drivers, the range reported is invalid.
+To fix that, you can add these options to the argument line:
+
+* invert_x : 1 to invert X axis
+* invert_y : 1 to invert Y axis
+* min_position_x : X minimum
+* max_position_x : X maximum
+* min_position_y : Y minimum
+* max_position_y : Y maximum
+* min_pressure : pressure minimum
+* max_pressure : pressure maximum
+* min_touch_major : width shape minimum
+* max_touch_major : width shape maximum
+* min_touch_minor : width shape minimum
+* max_touch_minor : height shape maximum
+* rotation : 0,90,180 or 270 to rotate
+
+An inverted display configuration will look like this::
+
+    [input]
+    # example for inverting touch events
+    display = mtdev,/dev/input/event0,invert_x=1,invert_y=1

+Auto Create Input Provider Config Entry for Available MT Hardware (linux only).
+===============================================================================
+
+Thanks to Marc Tardif for the probing code, taken from scan-for-mt-device.
+
+The device discovery is done by this provider. However, the reading of
+input can be performed by other providers like: hidinput, mtdev and
+linuxwacom. mtdev is used prior to other providers. For more
+information about mtdev, check :py:class:`~kivy.input.providers.mtdev`.
+
+Here is an example of auto creation::
+
+    [input]
+    # using mtdev
+    device_%(name)s = probesysfs,provider=mtdev
+    # using hidinput
+    device_%(name)s = probesysfs,provider=hidinput
+    # using mtdev with a match on name
+    device_%(name)s = probesysfs,provider=mtdev,match=acer
+
+    # using hidinput with custom parameters to hidinput (all on one line)
+    %(name)s = probesysfs,
+        provider=hidinput,param=min_pressure=1,param=max_pressure=99
+
+    # you can also match your wacom touchscreen
+    touch = probesysfs,match=E3 Finger,provider=linuxwacom,
+        select_all=1,param=mode=touch
+    # and your wacom pen
+    pen = probesysfs,match=E3 Pen,provider=linuxwacom,
+        select_all=1,param=mode=pen
+
+By default, ProbeSysfs module will enumerate hardware from the /sys/class/input
+device, and configure hardware with ABS_MT_POSITION_X capability. But for
+example, the wacom screen doesn't support this capability. You can prevent this
+behavior by putting select_all=1 in your config line. Add use_mouse=1 to also
+include touchscreen hardware that offers core pointer functionality.

+TUIO Input Provider
+===================
+
+TUIO is the de facto standard network protocol for the transmission of
+touch and fiducial information between a server and a client. To learn
+more about TUIO (which is itself based on the OSC protocol), please
+refer to http://tuio.org -- The specification should be of special
+interest.
+
+Configure a TUIO provider in the config.ini
+-------------------------------------------
+
+The TUIO provider can be configured in the configuration file in the
+``[input]`` section::
+
+    [input]
+    # name = tuio,<ip>:<port>
+    multitouchtable = tuio,192.168.0.1:3333
+
+Configure a TUIO provider in the App
+------------------------------------
+
+You must add the provider before your application is run, like this::
+
+    from kivy.app import App
+    from kivy.config import Config
+
+    class TestApp(App):
+        def build(self):
+            Config.set('input', 'multitouchscreen1', 'tuio,0.0.0.0:3333')
+            # You can also add a second TUIO listener
+            # Config.set('input', 'source2', 'tuio,0.0.0.0:3334')
+            # Then do the usual things
+            # ...
+            return
+'''

+    OSC messages:
+
+        * /tuio/2Dcur
+        * /tuio/2Dobj
+
+    You can easily extend the provider to handle new TUIO paths like so::
+
+        # Create a class to handle the new TUIO type/path
+        # Replace NEWPATH with the pathname you want to handle
+        class TuioNEWPATHMotionEvent(MotionEvent):

+                # arguments. you basically translate from TUIO args to Kivy
+                # MotionEvent variables. If all you receive are x and y
+                # values, you can do it like this:
+                if len(args) == 2:
+                    self.sx, self.sy = args
+                    self.profile = ('pos', )

+                super().depack(args)
+
+        # Register it with the TUIO MotionEvent provider.
+        # You obviously need to replace the PATH placeholders appropriately.
+        TuioMotionEventProvider.register('/tuio/PATH', TuioNEWPATHMotionEvent)
+
+    .. note::
+
+        The class name is of no technical importance. Your class will be
+        associated with the path that you pass to the ``register()``
+        function. To keep things simple, you should name your class after the
+        path that it handles, though.
