Linux Wacom Project HOWTO
5.1 - Adding the InputDevices
Navigation:
MAIN UP PREV NEXT INDEX ALL
The X Window system identifies the stylus (tip and side switches
of your pen), eraser (the other end of your pen if it is clickable),
cursor (your Wacom mouse), and pad (buttons, strips and rings on
your tablet if your tablet has any) as XInput devices. Most settings,
such as stylus pressure level and system cursor movement mode can be
done in /etc/X11/XF86Config or /etc/X11/xorg.conf configuration
file before X server starts or live through command-line
xsetwacom
or the simple GUI control panel wacomcpl while Wacom driver is running.
However, adding the InputDevice sections to your XF86Config/
xorg.conf file for Wacom devices is required. You should add these
devices to the ServerLayout section of your XF86Config/xorg.conf
file too.
We assume you are running Either XFree86 4.2 or later Or Xorg.
On some distributions, this file is called XF86Config-4.
Notice that the serial and USB configurations are different, so only
include the appropriate lines. The default serial devices are given.
For serial Tablet PCs, options "ForceDevice" should be included. You
should also change the device (e.g. ttyS0 or /dev/input/wacom) to the
correct one for your tablet. Tablet PC and Cintiq/PL/DTF models don't
support cursor type.
All the new driver options are listed in the manual page below.

The above four sections identify the stylus, eraser, cursor, touch, and pad devices
to XInput. Notice that all four reference the same device /dev/ttyS0 or
/dev/input/wacom depending on whether its a serial or USB tablet. Please refer to
Testing Tablet Detection and
Updated wacom.c pages to see which port your
tablet is actually mapped to.
The configuration options listed by your system's man page may be way out of date.
Below is an updated wacom man page which will be installed by default when you issue
make install.

...
EndSection
DESCRIPTION
wacom is an X input driver for Wacom devices.
The wacom driver functions as a pointer input device, and may be used
as the X server's core pointer.
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. USB tablets needs wacom Linux kernel driver being loaded
before this driver starts. Please check linuxwacom.sf.net for latest
updates of Wacom X and kernel drivers.
CONFIGURATION DETAILS
Please refer to xorg.conf(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. It can be useful
to define multiple devices with different active zones. Each device
supports the following entries:
Option "Type" "stylus"|"eraser"|"cursor"|"touch"|"pad"
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 and CintiqV5 ExpressKeys and menu strips, or
Graphire 4 and Bamboo tablet buttons and wheel/ring. It is
required for Intuos3, CintiqV5, Graphire 4, or 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 "USB" "on"
tells the driver to dialog with the tablet the USB way.
This option is mandatory for USB tablets.
Option "ForceDevice" "ISDV4"
tells the driver to dialog with the tablet the serial
Tablet PC way. It is a special Wacom IV protocol, called
ISDV4 protocol. This option is mandatory for serial Tablet
PCs only.
Option "DeviceName" "name"
sets the name of the X device.
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. The default value is 2. If you don't specify this
entry or your value is less than the default vaule or
greater than 100, the default value 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
and eraser is Absolute; cursor is Relative; pad mode is
decided according to its core option due to its nature of
not moving system cursor: Relative if it is a core device;
Absolute, otherwise.
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. The default action reported to Xinput is mouse button M
click. To ignore the button click, i.e., to not report any
button click event to Xinput, use "0" or "button 0".
Option "TPCButton" "on"|"off"
enables the stylus buttons as Tablet PC buttons, i.e.,
reports stylus button event only when its tip is pressed.
Default to "on" for Tablet PCs; "off" for all other models.
Option "Touch" "on"|"off"
enables the touch device for models that support touch
feature. Default to "on" for tablets with touch; "off" for
all other models.
Option "Capacity" "number"
sets touch sensitivity level for capacitive touch device,
where number can be an integer from -1 to 5. Default is 3
for capacitive tools and -1 for none capacitive tools.
Option "Speed" "Rspeed"
sets the cursor's relative movement speed to Rspeed. The
default value is 1.0. A Rspeed greater than 1.0 will speed
up the cursor's relative movement. A Rspeed less than 1.0
but greater than 0 will slow down the cursor's relative
movement. A Rspeed too close to 0 is not recommanded.
Option "Twinview" "horizontal"|"vertical"|"leftof"|"aboveof"
|"xinerama"|"none"
sets the orientation of TwinView to map the tablet to one
screen and to be able to move the screen cursor from one
screen to the other when tool reaches the edge of the
tablet. The cursor can be constrained in a specific screen
if "ScreenNo" option is added. If you want to map the
tablet to the whole desktop, you should NOT add this
option. The default is "none". Note: due to historic reason,
"horizontal" represents the "RightOf" and "vertical"
represents the "BelowOf" in acutal TwinView setup.
Option "TVResolution" "res0,res1"
specifies different resolutions for the two screens in
TwinView setup. For example, if the resolution of screen 0
(res0) is 1024x768 and screen 1 (res1) is 1280x1024, the
option will be set to:
Option "TVResolution" "1024x768,1280x1024"
This option is used only when TwinView option is not none.
It is unnecessary to add this option if your screens are
displaying in the same resolutions.
Option "ScreenNo" "n"
In a multi-monitor environment, specifies the screen number
in which the cursor can move. Here n starts from 0,
which indicates the first screen.
Option "MMonitor" "on"|"off"
turns on/off across monitor movement on a non-TwinView
multi-monitor desktop. If you have specific tablet mappings,
i.e. TopX/Y or BottomX/Y were set, the mapping will be
applied before rotation. The default is "on".
Option "Rotate" "CW"|"CCW"|"HALF"|"NONE"
rotates the tablet orientation counterclockwise (CCW) or
clockwise (CW) or 180 degrees (HALF). 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 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".
Option "KeepShape" "on"
When this option is enabled, the active zone begins
according to TopX and TopY. The bottom corner is adjusted
to keep the ratio width/height of the active zone the same
as the screen while maximizing the area described by TopX,
TopY, BottomX, BottomY.
Option "DebugLevel" "number"
sets the level of debugging info reported for the defined
device. There are 12 levels in use, specified by the
integers between 1 and 12. Once it is defined, all the
debug messages with a level less than or equal to the
"number" will be logged into /etc/X11/XFree86.0.log or
/etc/X11/Xorg.0.log.
Option "CommonDBG" "number"
sets the level of debugging info for all devices defined
for the same tablet. There are 12 levels in use, specified
by the integers between 1 and 12. Once it is defined, all
the debug messages with a level less than or equal to the
"number" will be logged into /etc/X11/XFree86.0.log or
/etc/X11/Xorg.0.log.
Option "CursorProx" "number"
sets the max distance from tablet to stop reporting
movement for cursor in relative mode. Default for Intuos
series is 10, Graphire series (including Volitos) is 42.
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 21UX). To see the serial
number associated with a device, run xsetwacom.
Option "Threshold" "number"
sets the pressure threshold used to generate a button 1
events of stylus. The default is MaxPressure*3/50.
