Minimum XFree version should be 3.3.3.1 because this version has extended XInput support, the second side switch works now and the blocking mouse effect has been fixed.
If you must use any prior version, XInput support should be available since 3.1.2.d.
XInput support in XFree is configured basically in a file called XF86Config. In most cases the XF86Config file is located in /etc or in /etc/x11. I will show now two very short configuration sections, the first works with XFree 3, the other is for XFree 4. I will explain then what can be changed and why this is needed.

Please notice the different syntax between XFree 3 and XFree 4:
In XFree 3 configuration is done in the section "XInput" with one subsection for each device. XFree 3 has keywords.
In XFree 4 configuration is done with one section "InputDevice" for each device. All Settings are "options", with one exception: the identifier statement. The Alwayscore option goes to the Serverlayout section.
Because the usage can be seen from the above examples, this difference will be considered as clear for the rest of the document.
XInput support in XFree is reached due to the use of modules. The wacom device driver module file for XFree 3 is called xf86Wacom.so, for XFree 4 the filename changed to wacom_drv.o. The files are located usually in /usr/X11R6/lib/modules/ or in /usr/X11R6/lib/modules/input. We have to specify in the "Module" section that we want to load this driver (look at above snippets):
XFree 3: Load "xf86Wacom.so"
XFree 4: Load "wacom"
This has to appear only once per XF86Config file.
The penpartner and graphire products simply recognize the type of a device, but they can not distinguish them. For example, you can not use two different pens, say, one configured red and one configured blue - all what these products say is: "I found a pen tip on my surface", or "I found an Eraser on my surface", or "I found a mouse on my surface".
XInput maps the device types to devices, these device types are later specified in XF86Config. For XFree 3 this is a subsection in the section XInput, for XFree 4 this goes to individuell InputDevice sections.
The devicetypes are:
WacomStylus Tip of a pen or airbrushWacomEraser Eraser of a pen or airbrushWacomCursor Mice, like graphire mouse, lens cursor, 4d-mouseAs you can see from above examples, device types are specified with the keyword "Devicetype" in XFree 3 and with Option "Type" in XFree 4.
You must give every configured device a unique name. This name will be used later in your program to talk to that device. You can choose this name free. This statement is mandantory. In XFree 3 you will use the "Devicename" keyword, in XFree 4 you will use the Identifier "name" keyword. Please notice that Identifier is not an Option !
XInput wants to know at which serial port this device can be found. This allows me to use two different tablets at the same time, for example a graphire connected to /dev/ttyS0 and a penpartner connected to /dev/ttyS1.
USB is treated as a serial line too, so this statement is mandantory. If you connect your product to the USB, you have to specify this with Option USB.
Example how to use the USB-Port (XF4):
Section "InputDevice" Driver "wacom" Identifier "stylus" Option "Device" "/dev/input/event0" Option "Type" "stylus" Option "Mode" "absolute" Option "USB" "on" Option "Tilt" "on" EndSection
Most people use both, the mouse and the tablet for core pointer functions. However, if you want to switch your mouse off and only will use your tablet, here comes the trick for that:
First, specify AllowMouseOpenFail in section ServerFlags. Then set the device to a file which must not exist (fake or dummy). Do not set it to /dev/null as this will eat up your CPU-time.
Example how to switch off the mouse (XF3):
Section "Pointer" Device "/dev/fake" #Phony device file ... EndSection
Example how to switch off the mouse (XF4):
Section "ServerLayout" ... InputDevice "Mouse0" "CorePointer" ... EndSection Section "InputDevice" Identifier "Mouse0" ... Option "Device" "/dev/fake" #Phony #device file Endsection
This statement controls how verbose the Wacom driver is. The Level goes from 0 to 10. If this statement is not given, DebugLevel 0 is used, which logs the very less.
Example (XFree 3):
SubSection "WacomStyLus" # Pen DeviceName "PenRed" # Name, choose it free ... DebugLevel 10 # be very verbose ... EndSubSection
Example (XFree 4):
Section "InputDevice" Identifier "PenRed" # Name, choose it free Option "Type" "stylus" ... Option "DebugLevel" "10" # be very verbose ... EndSection
The intuos product is more efficient than penpartner and graphire because it can distinguish many devices of the same type. This means that it is now possible to use two pens, one configured red and one configured blue. As you see, the use of device types is not enough information to handle different pens. Therefore, each intuos device, be it a pen, ink pen, mouse, or whatever has a serial number, which you can specify to aid XInput in resolving the right device. This would look like:
Example (XFree 3):
Section "XInput" SubSection "WacomStylus" # Pen DeviceName "PenRed" # Name, choose it free ... Serial 2609917443 # Serial Number of that device ... EndSubSection SubSection "WacomStylus" # another Pen DeviceName "PenBlue" # Name, choose it free ... Serial 2609918664 # Serial Number of that device ... EndSubSection EndSection
Example (XFree 4):
Section "InputDevice" Identifier "PenRed" # Name, choose it free Option "Type" "stylus" ... Option "Serial" "2609917443" ... EndSection Section "InputDevice" Identifier "PenBlue" # Name, choose it free Option "Type" "stylus" ... Option "Serial" "2609918664" ... EndSection
It should be said that combined input devices like pens have only one serial number. The driver uses the serial number it gets to recognize one specific pen and the device type to distinguish the tip of that specific pen from its eraser.
You should get a list of your different numbers.
(serial_num is in Line 4 Word 2).BEGIN xf86WcmProc dev=0x8354d60 priv=0x833e3f0 type=stylus flags=9 what=1 xf86WcmProc pWcm=0x8354d60 what=ON END xf86WcmProc Success what=1 dev=0x8354d60 priv=0x833e3f0 device_id=0x96 serial_num=2595227137 type=cursor [cursor] abs prox=false x=0 y=0 z=0 button=false buttons=0
If you set a device in mode absolute, this means, that the active area of the tablet will be mapped to the screen. Every time you go down to the tablet at the same point with an absolute device the pointer will appear at the same point of the screen.
If you set a device in mode relative, you will get the well known behavior of a mouse. This means, that if you take the mouse off from the surface, move it and go down again, the pointer does (ideally) not move.
Example (XFree 3):
Section "XInput" SubSection "WacomStylus" # Pen DeviceName "PenRed" # Name, choose it free ... Mode absolute ... EndSubSection EndSection
Example (XFree 4):
Section "InputDevice" Identifier "PenRed" # Name, choose it free Option "Type" "stylus" ... Option "Mode" "absolute" ... EndSection
XFree knows two pointers: one with only the standard features (buttons, moving-capabilities), which is used for selecting menus, text, clicking buttons and doing other controlling stuff. This is the Core Device.
The other pointer is used by applications which want more information, like pressure and tilt.
This is the extension device.
Starting with version 3.3.3.1, the Statement AlwaysCore tells the driver that it should send both types of events.
If you do not specify Alwayscore in your XF86Config, then this device is initially used as extension device, this means it is usable only in applications but you can not control the menus of your window manager with it.
If Alwayscore is given, then your device acts as core pointer (in addition to the mouse) as well as it sends tilt and pressure information to applications which opened the device in extension mode.
You can configure two different logical devices, one in Core-Mode and one in Extension-Mode, to the same physical device.
To do so, simply type two identical sections, only the DeviceName statement must differ. Then specify AlwaysCore only for the last section.
Example (XFree 3):
Section "XInput" SubSection "WacomStylus" # Pen DeviceName "PenRed" # Name, choose it free ... AlwaysCore ... EndSubSection EndSection
For XFree 4, this is not an option in the InputDevice section, it goes to the Serverlayout section and can be one of: AlwaysCore / SendCoreEvents or CorePointer:
Example (XFree 4):
Section "ServerLayout" Identifier "XFree86 Configured" Screen 0 "Screen0" 0 0 ... InputDevice "icursor" "AlwaysCore" EndSection
This statement sets the buffer size that is used to cache motion events.
Example (XFree 3):
Section "XInput" SubSection "WacomStylus" # Pen DeviceName "PenRed" # Name, choose it free ... HistorySize 200 ... EndSubSection EndSection
Example (XFree 4):
Section "InputDevice" Identifier "PenRed" # Name, choose it free Option "Type" "stylus" ... Option "HistorySize" "200" ... EndSection
This statement specifies how many units the device must move before the driver moves the pointer. This can be necessary if very large resolutions are used.
Example (XFree 3):
Section "XInput" SubSection "WacomStylus" # Pen DeviceName "PenRed" # Name, choose it free ... Suppress 10 ... EndSubSection EndSection
Example (XFree 4):
Section "InputDevice" Identifier "PenRed" # Name, choose it free Option "Type" "stylus" ... Option "Suppress" "10" ... EndSection
This works only with intuos series tablets.
TiltMode enables sending of tilt information for intuos devices. If this statement is missing, only pressure information is transferred.
Example (XFree 3):
Section "XInput" SubSection "WacomStylus" # Pen DeviceName "PenRed" # Name, choose it free ... TiltMode ... EndSubSection EndSection
Example (XFree 4):
Section "InputDevice" Identifier "PenRed" # Name, choose it free Option "Type" "stylus" ... Option "Tilt" "on" ... EndSection
Max[axis] limits / owerwrites the max[axis] values normaly retrieved from the tablet. More or less developer stuff.
Resolution[axis] presets the resolution[axis] values normaly retrieved from the tablet. More or less developer stuff.
These four statements allow to reduce the active area of the tablet. My intuos A4 oversize, for example, is so big that you can not do painting work with it because the ways of the pen are too long. I use these four Statements to tell the driver that it should map only the lower left quarter of the tablet to the screen.
It is possible to define more than one active area on the same tablet: Define as many subsections as you need with the same Port Statement but with different Top... statements and Devicenames. This results in multiple logical devices all of them restricted to their individual bounds. You may use one device in absolute mode and one in relative mode as well.
Example (XFree 3):
Section "XInput" SubSection "WacomStylus" # Pen DeviceName "PenRed" # Name, choose it free ... TopX 0 TopY 5000 BottomX 5000 BottomY 10000 ... EndSubSection EndSection
Example (XFree 4):
Section "InputDevice" Identifier "PenRed" # Name, choose it free Option "Type" "stylus" ... Option "TopX" "0" Option "TopY" "5000" Option "BottomX" "5000" Option "BottomY" "10000" ... EndSection
If you use the above four statements, you sometimes want to make some calculations on the size and position of the rectangle to be defined. Often the maximal tablet coordinates and the resolution are needed for this. To get these values, start your server: X 2>t. Kill the X-Server (usually Ctrl+Alt+Backspace) and do a grep "X=" t .You should get back the values in question.
(--) Wacom IV tablet maximum X=5103 maximum Y=3711 X resolution=1000 Y resolution=1000 suppress=6 (--) Wacom tablet top X=0 top Y=0 bottom X=5103 bottom Y=3711 (--) Wacom tablet top X=0 top Y=0 bottom X=5103 bottom Y=3711 (--) Wacom tablet top X=0 top Y=0 bottom X=5103 bottom Y=3711
This option uses the TopX, TopY statements (or their built in defaults, if omitted) and adjusts the BottomX, BottomY statements so that
Any given BottomX, BottomY statement is ignored, because these values will be calculated.
Example (XFree 3):
Section "XInput" SubSection "WacomStylus" # Pen DeviceName "PenRed" # Name, choose it free ... KeepShape ... EndSubSection EndSection
Example (XFree 4):
Section "InputDevice" Identifier "PenRed" # Name, choose it free Option "Type" "stylus" ... Option "KeepShape" "1" ... EndSection
This is available since alpha 16 and is used to control the minimum pressure that is needed to detect that a tool is pressed on the surface. It works with intuos and graphire. Please note that the integer value has to be coded as String, unlike all other integer values.
Example (XFree 3):
Section "XInput" SubSection "WacomStylus" # Pen DeviceName "PenRed" # Name, choose it free ... Threshold "5" ... EndSubSection EndSection
Example (XFree 4):
Section "InputDevice" Identifier "PenRed" # Name, choose it free Option "Type" "stylus" ... Option "Treshold" "5" ... EndSection
USB tells the driver that the serial line is the usb port. This needs a Kernel 2.4 with usb enabled. Alpha 20 driver only supports absolute devices. Here is an example for use with XFree 4.
Please read the Wacom-USB-mini-HOWTO by Arnauld Claden and the USB-'Micro-HOWTO' by Semyon Sosin for more information on USB setup.
