wacom is an X input driver for Wacom devices.
The wacom driver functions as a pointer input device.
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.
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.
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
"Pressure2K" "bool"
- reduces the pressure range to the range of 0 to 2048 for backwards
compatibility with applications that have this range hardcoded. See
section BUGS. This option should not be used unless the user runs
one or more applications that rely on a hardcoded pressure range.
- 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.
Single_finger_(1FG)">Single_finger_(1FG)">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)">Two_finger_(2FG)">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.
In version 0.34, the driver's pressure range increased from 2048
steps to 65536 steps. The pressure axis range is advertised through the X
Input Protocol but some applications have the previous pressure range
hardcoded and cannot handle pressure values above 2048. This is an
application bug but for backwards-compatibility with such applications, this
driver provides the Pressure2K option to reduce the range to 2048
steps. Note that this setting applies to the device. Once applied, all
applications will see the reduced pressure range. It is not possible to
provide this setting on a per-application basis.
