DESCRIPTION

       wacom is an X input driver for Wacom devices.

       The wacom driver functions as a pointer input device.

SUPPORTED HARDWARE

       This  driver  supports  the  Wacom IV and Wacom V protocols. Serial tablets only need this
       driver.  USB tablet support is available on some Linux platforms and  requires  the  wacom
       kernel driver being loaded before this driver starts.

       Please  check  http://linuxwacom.sourceforge.net  for latest updates of Wacom X and kernel
       drivers.

DRIVER-INTERNAL DEVICE HOTPLUGGING

       When input device hotplugging in the X server is enabled and no InputDevice section exists
       for  a  compatible  tablet  device and an InputClass section (see xorg.conf.d(5x)) assigns
       this driver for the device, the wacom  driver  creates  multiple  X  devices  for  each  a
       physical  device,  one  X  device  for each available tool. The list of tools is hardware-
       dependent. See Option Type as outlined in the CONFIGURATION DETAILS section.

       These tool-specific devices are referred to as parent device and  dependent  device.   The
       parent  device  is the one presented by the system and the one that causes the X server to
       load the wacom driver. This parent device then causes the automatic  addition  of  several
       dependent  devices.  If the parent device is unplugged or otherwise removed, the dependent
       devices will be automatically removed as well.

       Dependent devices may be assigned  tool-specific  options  through  additional  InputClass
       sections. We recommend that a MatchDriver wacom line is used in these sections in addition
       to the user-specific pattern.

       Match directives are applied by the X server before the driver is selected.  The type name
       of  the  parent device is appended by the driver. It is not possible to use a MatchProduct
       directive to match against this appended type name.

CONFIGURATION DETAILS

Please refer to xorg.conf(5x) or xorg.conf.d(5x) 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.

Multiple instances of the Wacom devices can cohabit. Each device supports the following
entries:

Option "Type" "stylus"|"eraser"|"cursor"|"pad"|"touch"
sets the type of tool the device represents. This option is mandatory. The
core options, such as "SendCoreEvents" or "AlwaysCore", are unnecessary in
Gimp if you don't need to move system cursor outside of Gimp drawing area.
"pad" is for Intuos 3 or Cintiq 21UX tablet ExpressKeys/menu strips, and
Graphire 4 or Bamboo tablet buttons, wheel, and/or ring. It is required for
Intuos3, CintiqV5, Graphire 4, and Bamboo if you want to use keystroke
features. "pad" is reported as a second tool in the driver. "touch" is for
the tablet with touch support. Right now only a few Tablet PCs have this
feature.

Option "Device" "path"
sets the path to the special file which represents serial line where the
tablet is plugged. You have to specify it for each subsection with the same
value if you want to have multiple devices with the same tablet. This option
is mandatory.

Option "Suppress" "number"
sets the position increment under which not to transmit coordinates. This
entry must be specified only in the first Wacom subsection if you have
multiple devices for one tablet. If you don't specify this entry, the default
value, which is 2, will be used. To disable suppression, the entry should be
specified as 0. When suppress is defined, an event will be sent only when at
least one of the following conditions is met:

the change between the current X coordinate and the previous one is
greater than suppress;

the change between the current Y coordinate and the previous one is
greater than suppress;

the change between the current pressure and the previous one is
greater than suppress;

the change between the current degree of rotation and the previous
one of the transducer is greater than suppress;

the change between the current absolute wheel value and the previous
one is equal to or greater than suppress;

the change between the current tilt value and the previous one is
equal to or greater than suppress (if tilt is supported);

relative wheel value has changed;

button value has changed;

proximity has changed.

Option "Mode" "Relative"|"Absolute"
sets the mode of the device. The default value for stylus, pad and eraser is
Absolute; cursor is Relative; touch defaults to Relative for tablets with
touch pads and Absolute for touch screens.

Option "TopX" "number"
X coordinate of the top corner of the active zone. Default to 0.

Option "TopY" "number"
Y coordinate of the top corner of the active zone. Default to 0.

Option "BottomX" "number"
X coordinate of the bottom corner of the active zone. Default to width of the
tablet.

Option "BottomY" "number"
Y coordinate of the bottom corner of the active zone. Default to height of
the tablet.

Option "ButtonsOnly" "on"|"off"
disables the device's motion events. Default to off.

Option "ButtonM" "AC"
reports an action AC when button M is pressed, where M is one of the device
supported button numbers, it can be 1 to 32. Wacom uses a driver-internal
button mapping, where any physical button appears to the X server as the
button specified by the ButtonM mapping. Hence, if two physical buttons have
the same ButtonM mapping, the server will think they are the same physical
button. The default action reported to the X server is mouse button M click.
Because X uses buttons 4, 5, 6, and 7 as the four scrolling directions,
physical buttons 4 and higher are mapped to 8 and higher by default. Only
simple button presses can be configured here; for more complex actions, use
xsetwacom(1). To ignore the button click, i.e., to not report any button
click event to the X server, use "0" or "button 0".

Option "TPCButton" "on"|"off"
enables the stylus buttons as Tablet PC buttons. If enabled, the stylus
reports button events only when its tip is pressed. If any button is down,
pressing the tip reports a button event for the button. Otherwise if no button
is down, the tip reports as usual. Default to "on" for Tablet PCs; "off" for
all other models. Only available on the stylus tool.

Option "Touch" "on"|"off"
enables touch events for touch devices, i.e., system cursor moves when user
touches the tablet. Default to "on" for devices that support touch; "off" for
all other models.

Option "Rotate" "CW"|"CCW"|"HALF"|"NONE"
rotates the tablet orientation counterclockwise (CCW) or clockwise (CW) or 180
degrees (HALF). If you have specific tablet mappings, i.e. TopX/Y or
BottomX/Y were set, the mapping will be applied before rotation. Rotation must
be applied to the parent device (usually the stylus), rotation settings on in-
driver hotplugged devices (see DRIVER-INTERNAL DEVICE HOTPLUGGING ) will be
ignored. The default is "NONE".

Option "PressCurve" "x1,y1,x2,y2"
sets pressure curve by control points x1, y1, x2, and y2. Their values are in
range from 0..100. The pressure curve is interpreted as Bezier curve with 4
control points, the first and the last control point being fixed on the
coordinates 0/0 and 100/100, respectively. The middle control points are
adjustible by this setting and thus define the shape of the curve. The input
for linear curve (default) is "0,0,100,100"; slightly depressed curve (firmer)
might be "5,0,100,95"; slightly raised curve (softer) might be "0,5,95,100".
The pressure curve is only applicable to devices of type stylus or eraser,
other devices do not honor this setting.

Option "DebugLevel" "number"
sets the level of debugging info for tool-specific messages. There are 12
levels, specified by the integers between 1 and 12. All debug messages with a
level less than or equal to the "number" will be logged into the Xorg log
file. This option is only available if the driver was built with debugging
support.

Option "CommonDBG" "number"
sets the level of debugging info for common (i.e. not tool-specific) code
paths on the tablet. There are 12 levels, specified by the integers between 1
and 12. All debug messages with a level less than or equal to the "number"
will be logged into the Xorg log file. This option is only available if the
driver was built with debugging support.

Option "GrabDevice" "bool"
sets whether the underlying event device will be grabbed by the driver to
prevent the data from leaking to /dev/input/mice. When enabled, while the X
server is running, no other programs will be able to read the event stream.
Default: "false".

Option "CursorProx" "number"
sets the max distance from tablet to stop reporting movement for the cursor.
Default for Intuos series is 10, for Graphire series (including Volitos) is
42. Only available for the cursor/puck device.

Option "RawSample" "number"
Set the sample window size (a sliding average sampling window) for
incoming input tool raw data points. Default: 4, range of 1 to 20.

Option "Serial" "number"
sets the serial number associated with the physical device. This allows to
have multiple devices of the same type (i.e. multiple pens). This option is
only available on wacom V devices (Intuos series and Cintiq 21U). To see
which serial number belongs to a device, you need to run the utility program,
xsetwacom, which comes with linuxwacom package.

Option "ToolSerials" "number[,type[,label]][;...]"
sets the list of serial numbered devices that need to be hotplugged for a
physical device. The 'type' option may be any of "pen", "airbrush", "artpen",
or "cursor". This option is only available on wacom V devices (Intuos series
and Cintiq 21U). To see which serial number belongs to a device, you need to
run the utility program, xsetwacom, that comes with this driver.

Option "Threshold" "number"
sets the pressure threshold used to generate a button 1 events of stylus. The
threshold applies to the normalised pressure range of [0..2048]. The default
is 27.

Option "Gesture" "bool"
Enable or disable multi-finger in-driver gesture support on the device.
Default: off unless the tablet supports multi-touch. Note that disabling this
option may allow the desktop environment to detect multi-finger gestures
instead.

Option "ZoomDistance" "number"
If Option "Gesture" is enabled, this option specifies the minimum movement
distance before a zoom gesture is recognized.

Option "ScrollDistance" "number"
If Option "Gesture" is enabled, this option specifies the minimum movement
distance before a scroll gesture is recognized.

Option "TapTime" "number"
If Option "Gesture" is enabled, this option determines the maximum time of a
touch event to be recognized as tap. A press and release event shorter than
TapTime generates button press and release events. Presses longer than TapTime
do not generate button events, only motion events.

Option "PressureRecalibration" "bool"
Allows to disable pressure recalibration. Default: true. If the initial
pressure of a device is != 0 the driver recalibrates the pressure range. This
is to account for worn out devices. The downside is that when the user hits
the tablet very hard the initial pressure reading may be unequal to zero even
for a perfectly good pen. If the consecutive pressure readings are not higher
than the initial pressure by a threshold no button event will be generated.
This option allows to disable the recalibration.

TOUCH GESTURES

   Single finger (1FG)
       Left click: tap, actual click happens after TapTime period elapses.

       Left click drag: tap to select, quickly (within TapTime  period)  touch  selection  again.
       Then drag.  Available on touchpads, e.g. BambooPT, not touchscreens.

   Two finger (2FG)
       Right click: one finger down + tap second finger

       Vertical  scroll:  two  fingers  side  by side (in any orientation) moving vertically with
       constant separation initiates a vertical scroll.  By driver default a gesture  up  results
       in  a  scroll down event (the document moves up) and a gesture down results in a scroll up
       event (moving the document down).

       Horizontal  scroll:  two  fingers  side  by  side  held  at  a  constant  distance  moving
       horizontally  initiates  a  horizontal  scroll.  A gesture to the left results in a scroll
       right event (the document moves left) and a gesture right results in a scroll  left  event
       (moving the document right).

       Zoom in: two separated fingers side by side, bring together i.e. pinch.

       Zoom out: two fingers side by side, spread.  Not all applications support zoom.
