______________________________________________________________________
1. Introduction
This document describes mouse support in X.org Foundation's X11R6.8
server.
Mouse configuration has often been mysterious task for novice users.
However, once you learn several basics, it is straightforward to write
the mouse "InputDevice" section in the xorg.conf file by hand.
2. Supported Hardware
The X.org Foundation X server supports three classes of mice: serial,
bus and PS/2 mice.
Serial mouse
The serial mouse has been the most popular pointing device for
PCs. There have been numerous serial mouse models from a number
of manufactures. Despite the wide range of variations, there
have been relatively few protocols (data format) with which the
serial mouse talks to the host computer.
The modern serial mouse conforms to the PnP COM device
specification so that the host computer can automatically detect
the mouse and load an appropriate driver. The X server supports
this specification and can detect popular PnP serial mouse
models on most platforms.
Bus mouse
The bus mouse connects to a dedicated interface card in an
expansion slot. Some video cards, notably those from ATI, and
integrated I/O cards may also have a bus mouse connector. Some
bus mice are known as `InPort mouse'.
Note that some mouse manufactures have sold a package including
a serial mouse and a serial interface card. Don't confuse this
type of products with the genuine bus mouse.
PS/2 mouse
They are sometimes called `Mouse-port mouse'. The PS/2 mouse is
becoming increasingly common and popular.
The PS/2 mouse is an intelligent device and may have more than
three buttons and a wheel or a roller. The PS/2 mouse is
usually compatible with the original PS/2 mouse from IBM
immediately after power up. The PS/2 mouse with additional
features requires a specialized initialization procedure to
enable these features. Without proper initialization, it
behaves as though it were an ordinary two or three button mouse.
USB mouse
USB (Universal Serial Bus) ports are present on most modern
computers. Several devices can be plugged into this bus,
including mices and keyboards.
The server includes support for USB mices on some systems.
Many mice nowadays can be used both as a serial mouse and as a PS/2
mouse. They has a logic to distinguish which interface it is
connected to. However, the mouse which is not marketed as compatible
with both serial and PS/2 mouse interface lacks this logic and cannot
be used in such a way, even if you can find an appropriate adapter
with which you can connect the PS/2 mouse to a serial port or visa
versa.
X11R6.8 supports the mouse with a wheel, a roller or a knob. Its
action is detected as the Z (third) axis motion of the mouse. As the
X server or clients normally do not use the Z axis movement of the
pointing device, a configuration option, "ZAxisMapping", is provided
to assign the Z axis movement to another axis or a pair of buttons
(see below).

*1 Refer to the following sections for details.
*2 X11R6.8/OS2 will support any type of mouse that the OS supports,
whether it is serial, bus mouse, or PnP type.
3.2. BSD/OS
No testing has been done with BSD/OS.
3.3. FreeBSD
FreeBSD supports the "SysMouse" protocol which must be specified when
the moused daemon is running in versions 2.2.1 or later.
When running the mouseddaemon, you must always specify the
/dev/sysmouse device and the "SysMouse" protocol to the X server,
regardless of the actual type of your mouse.
FreeBSD versions 2.2.6 or later include the kernel-level support for
extended PS/2 mouse protocols and there is no need to specify the
exact protocol name to the X server. Instead specify the "PS/2" or
"Auto" protocol and the X server will automatically make use of the
kernel-level support.
In fact, "Auto" protocol support is really efficient in these
versions. You may always specify "Auto" to any mouse, serial, bus or
PS/2, unless the mouse is an old serial model which doesn't support
PnP.
FreeBSD versions 2.2.5 or earlier do not support extended PS/2 mouse
protocols ("xxxPS/2"). Always specify the "PS/2" protocol for any
PS/2 mouse in these versions regardless of the brand of the mouse.
FreeBSD versions 3.1 or later have support for USB mice. Specify the
"Auto" protocol for the /dev/ums0 device. (If the moused daemon is
running for the USB mouse, you must use /dev/sysmouse instead of
/dev/ums0 as explained above.) See the ums(4) manual page for details.
3.4. FreeBSD(98)
The PS/2 mouse is not supported.
3.5. Interactive Unix
The PnP serial mouse support (the "Auto" protocol) is not supported
for the moment.
The bus mouse and PS/2 mouse should be supported by using the
appropriate device drivers. Use /dev/mouse for the "BusMouse"
protocol and /dev/kdmouse for the "PS/2" protocol. These protocols
are untested but may work. Please send success/failure reports to
<michael.rohleder@stadt-frankfurt.de>.
3.6. Linux
All protocol types should work.
3.7. Linux/98
The PS/2 mouse is not supported.
3.8. LynxOS
The PnP serial mouse support (the "Auto" protocol) is disabled in
LynxOS, because of limited TTY device driver functionality.
3.9. NetBSD
NetBSD 1.3.x and former does not support extended PS/2 mouse protocols
("xxxPS/2"). The PS/2 mouse device driver /dev/pms emulates the bus
mouse. Therefore, you should always specify the "BusMouse" protocol
for any PS/2 mouse regardless of the brand of the mouse.
The "wsmouse" protocol introduced in NetBSD 1.4 along with the wscons
console driver is supported. You need to run binaries compiled on
NetBSD 1.4 to have support for it though. Use "/dev/wsmouse0" for the
device. Refer to the wsmouse(4) manual page for kernel configuration
informations.
This driver also provides support for USB mices. See the ums(4) manual
page for details.
3.10. NetBSD/pc98
The PS/2 mouse is not supported.
3.11. OpenBSD
The raw PS/2 mouse device driver /dev/psm0 uses the raw PS/2 mouse
protocol.
OpenBSD 2.2 and earlier does not support extended PS/2 mouse protocols
("xxxPS/2") . Therefore, you should specify the "PS/2" protocol for
any PS/2 mouse regardless of the brand of the mouse.
OpenBSD 2.3 and later support all extended PS/2 mouse protocols. You
can select the "Auto" protocol for PnP PS/2 mice or any specific
extended ("xxxPS/2") protocol for non PnP mice.
There is also a cooked PS/2 mouse device driver /dev/pms0 which
emulates the bus mouse. Specify the "BusMouse" protocol for any PS/2
mouse regardless of the brand of the mouse when using this device.
XFree86 3.3.6 support USB mices on OpenBSD 2.6 and later though the
generic Human Interface Device (hid) /dev/uhid*. Select the "usb"
protocol and the /dev/uhid* instance corresponding to your mouse as
the device name.
3.12. OS/2
X11R6.8/OS2 always uses the native mouse driver of the operating
system and will support any type of pointer that the OS supports,
whether it is serial, bus mouse, or PnP type. If the mouse works
under Presentation Manager, it will also work under X11R6.8/OS2.
Always specify "OSMouse" as the protocol type.
3.13. SCO
The bus and PS/2 mouse are supported with the "OSMouse" protocol type.
The "OSMouse" may also be used with the serial mouse.
3.14. Solaris
Testing has been done with Solaris 2.5.1, 2.6, 7, 8, 9 and pre-release
versions of Solaris 10. Logitech and Microsoft bus mice have not been
tested, but might work with the /dev/logi and /dev/msm devices.
Standard 2 and 3 button PS/2 mice work with the "PS/2" protocol type
and the /dev/kdmouse device. USB mice work with the "VUID" protocol
type and the /dev/mouse device. The PnP serial mouse support (the
"Auto" protocol) has been tested and does not work. The "Auto"
protocol can however detect PS/2 and USB mice correctly.
Additional USB mice can be connected using the "VUID" protocol type
and the appropriate "/dev/usb/hid" device with the Option
"StreamsModule" "usbms" line included in the associated "InputDevice"
section.
3.15. SVR4
The bus and PS/2 mouse may be supported with the "Xqueue" protocol
type.
The "Xqueue" may also be used with the serial mouse.
The PnP serial mouse support (the "Auto" protocol) is not tested.
3.16. PANIX
The PC/AT version of PANIX supports the bus and PS/2 mouse with the
"Xqueue" protocol type. The PC-98 version of PANIX supports the bus
mouse with the "Xqueue" protocol type.
4. Configuring Your Mouse
Before using the xorgconfig program to set up mouse configuration, you
must identify the interface type, the device name and the protocol
type of your mouse. Blindly trying every possible combination of
mouse settings will lead you nowhere.
The first thing you need to know is the interface type of the mouse
you are going to use. It can be determined by looking at the
connector of the mouse. The serial mouse has a D-Sub female 9- or
25-pin connector. The bus mice have either a D-Sub male 9-pin
connector or a round DIN 9-pin connector. The PS/2 mouse is equipped
with a small, round DIN 6-pin connector. Some mice come with adapters
with which the connector can be converted to another. If you are to
use such an adapter, remember that the connector at the very end of
the mouse/adapter pair is what matters.
The next thing to decide is a device node to use for the given
interface. For the bus and PS/2 mice, there is little choice; your OS
most possibly offers just one device node each for the bus mouse and
PS/2 mouse. There may be more than one serial port to which the
serial mouse can be attached.
The next step is to guess the appropriate protocol type for the mouse.
The X server may be able to select a protocol type for the given mouse
automatically in some cases. Otherwise, the user has to choose one
manually. Follow the guidelines below.
Bus mouse
The bus and InPort mice always use "BusMouse" protocol
regardless of the brand of the mouse.
Some OSs may allow you to specify "Auto" as the protocol type
for the bus mouse.
PS/2 mouse
The "PS/2" protocol should always be tried first for the PS/2
mouse regardless of the brand of the mouse. Any PS/2 mouse
should work with this protocol type, although wheels and other
additional features are unavailable in the X server.
After verifying the mouse works with this protocol, you may
choose to specify one of "xxxPS/2" protocols so that extra
features are made available in the X server. However, support
for these PS/2 mice assumes certain behavior of the underlying
OS and may not always work as expected. Support for some PS/2
mouse models may be disabled all together for some OS platforms
for this reason.
Some OSs may allow you to specify "Auto" as the protocol type
for the PS/2 mouse and the X server will automatically adjust
itself.
Serial mouse
The server supports a wide range of mice, both old and new. If
your mouse is of a relatively new model, it may conform to the
PnP COM device specification and the X server may be able to
detect an appropriate protocol type for the mouse automatically.
Specify "Auto" as the protocol type and start the X server. If
the mouse is not a PnP mouse, or the X server cannot determine a
suitable protocol type, the server will print the following
error message and abort.
<mousename>: cannot determine the mouse protocol
If the X server generates the above error message, you need to
manually specify a protocol type for your mouse. Choose one from
the following list:
+o GlidePoint
+o IntelliMouse
+o Logitech
+o Microsoft
+o MMHittab
+o MMSeries
+o MouseMan
+o MouseSystems
+o ThinkingMouse
When you choose, keep in mind the following rule of thumb:
1. "Logitech" protocol is for old serial mouse models from
Logitech. Modern Logitech mice use either "MouseMan" or
"Microsoft" protocol.
2. Most 2-button serial mice support the "Microsoft" protocol.
3. 3-button serial mice may work with the "Mousesystems"
protocol. If it doesn't, it may work instead with the
"Microsoft" protocol although the third (middle) button won't
function. 3-button serial mice may also work with the
"Mouseman" protocol under which the third button may function
as expected.
4. 3-button serial mice may have a small switch at the bottom of
the mouse to choose between ``MS'' and ``PC'', or ``2'' and
``3''. ``MS'' or ``2'' usually mean the "Microsoft"
protocol. ``PC'' or ``3'' will choose the "MouseSystems"
protocol.
5. If the serial mouse has a roller or a wheel, it may be
compatible with the "IntelliMouse" protocol.
6. If the serial mouse has a roller or a wheel and it doesn't
work with the "IntelliMouse" protocol, you have to use it as
a regular 2- or 3-button serial mouse.
If the "Auto" protocol is specified and the mouse seems working,
but you find that not all features of the mouse is available, that
is because the X server does not have native support for that model
of mouse and is using a ``compatible'' protocol according to PnP
information.
If you suspect this is the case with your mouse, please enter a
bugreport in bugzilla.freedesktop.org, using the xorg product.
USB mouse
If your mouse is connected to the USB port, it can either be
supported by the "Auto" protocol, or by an OS-specific protocol
(see below), or as a generic Human Interface Device by the "usb"
protocol.
Standardized protocols
Mouse device drivers in your OS may use the standardized
protocol regardless of the model or the class of the mouse. For
example, SVR4 systems may support "Xqueue" protocol. In FreeBSD
the system mouse device /dev/sysmouse uses the "SysMouse"
protocol. Please refer to the OS support section of this file
for more information.
5. xorg.conf Options
The old Pointer section has been replaced by a more general
InputDevice section. The following is a minimal example of an
InputDevice section for a mouse:
______________________________________________________________________
Section "InputDevice"
Identifier "Mouse 1"
Driver "mouse"
Option "Device" "/dev/mouse"
Option "Protocol" "Auto"
EndSection
______________________________________________________________________
The mouse driver supports the following config file options:
5.1. Buttons
This option tells the X server the number of buttons on the mouse.
Currently there is no reliable way to automatically detect the correct
number. This option is the only means for the X server to obtain it.
The default value is three.
Note that if you intend to assign Z axis movement to button events
using the ZAxisMapping option below, you need to take account of those
buttons into N too.
Option "Buttons" "N"
5.2. ZAxisMappping
This option maps the Z axis (wheel) motion to buttons or to another
axis.
Option "ZAxisMapping" "X"
Option "ZAxisMapping" "Y"
Option "ZAxisMapping" "N1 N2"
Option "ZAxisMapping" "N1 N2 N3 N4"
The first example will map the Z axis motion to the X axis motion.
Whenever the user moves the wheel/roller, its movement is reported as
the X axis motion. When the wheel/roller stays still, the real X axis
motion is reported as is. The third example will map negative Z axis
motion to the button N1 and positive Z axis motion to the button N2.
If this option is used and the buttons N1 or N2 actually exists in the
mouse, their actions won't be detected by the X server.
The last example is useful for the mouse with two wheels of which the
second wheel is used to generate horizontal scroll action, and the
mouse which has a knob or a stick which can detect the horizontal
force applied by the user. The motion of the second wheel will be
mapped to the buttons N3, for the negative direction, and N4, for the
positive direction. If the buttons N3 and N4 actually exist in this
mouse, their actions won't be detected by the X server.
NOTE #1: horizontal movement may not always be detected by the current
version of the X11R6.8 X servers, because there appears to be no
accepted standard as to how the horizontal direction is encoded in
mouse data.
NOTE #2: Some mice think left is the negative horizontal direction,
others may think otherwise. Moreover, there are some mice whose two
wheels are both mounted vertically, and the direction of the second
vertical wheel does not match the first one's.
You need to edit the xorg.conf file by hand to change this option if
the default value of "4 5 6 7" does not match the needs of your
configuration.
5.3. Resolution
The following option will set the mouse device resolution to N counts
per inch, if possible:
Option "Resolution" "N"
Not all mice and OSs can support this option.
5.4. Drag Lock Buttons
Some people find it difficult or inconvenient to hold a trackball
button down, while at the same time moving the ball. Drag lock buttons
simulate the holding down of another button. When a drag lock button
is first pressed, its target buttons is "locked" down until the
second time the lock button is released, or until the button itself is
pressed and released. This allows the starting of a drag, the movement
of the trackball, and the ending of the drag to be separate
operations.
Option "DragLockButtons" "W X Y Z"
This option consists of pairs of buttons. Each lock button number is
followed by the number of the button that it locks. In the above,
button number "W" is a drag lock button for button "X" and button
number "Y" is a drag lock button for button "Z".
It may not be desirable to use multiple buttons as drag locks.
Instead, a "master drag lock button" may be defined. A master drag
lock button acts as a "META" key. After a master lock button is
released, the next button pressed is "locked" and not released until
the second time the real button is released.
Option "DragLockButtons" "M"
Since button "M" is unpaired it is a master drag lock button.
6. Mouse Gallery
In all of the examples below, it is assumed that /dev/mouse is a link
to the appropriate serial port or PS/2 mouse device.
6.1. MS IntelliMouse (serial, PS/2)
This mouse has a wheel which also acts as the button 2 (middle
button). The wheel movement is recognized as the Z axis motion. This
behavior is not compatible with XFree86 versions prior to 3.3.2, but
is more consistent with the support for other mice with wheels or
rollers. If you want to make the wheel behave like before, you can
use the "ZAxisMapping" option as described above.

6.7. ALPS GlidePoint (serial, PS/2)
The serial version of this pad device has been supported since XFree86
3.2. `Tapping' action is interpreted as the fourth button press.
(IMHO, the fourth button of GlidePoint should always be mapped to the
first button in order to make this pad behave like the other pad
products.)

7. Configuration Examples
This section shows some example InputDevice section for popular mice.
All the examples assume that the mouse is connected to the PS/2 mouse
port, and the OS supports the PS/2 mouse initialization. It is also
assumed that /dev/mouse is a link to the PS/2 mouse port.
Logitech MouseMan+ has 4 buttons and a wheel. The following example
makes the wheel movement available as the button 5 and 6.

You can change button number assignment using the xmodmap command
AFTER you start the X server with the above configuration. You may
not like to use the wheel as the button 2 and rather want the side
button (button 4) act like the button 2. You may also want to map the
wheel movement to the button 4 and 5. This can be done by the
following command:
xmodmap -e "pointer = 1 6 3 2 4 5"
After this command is run, the correspondence between the buttons and
button numbers will be as shown in the following table.
Physical Buttons Reported as:
------------------------------------
1 Left Button Button 1
2 Wheel Button Button 6
3 Right Button Button 3
4 Side Button Button 2
5 Wheel Negative Move Button 4
6 Wheel Positive Move Button 5
For the MS IntelliMouse Explorer which as a wheel and 5 buttons, you
may have the following InputDevice section.

Option "Protocol" "ExplorerPS/2"
Option "Buttons" "7"
Option "ZAxisMapping" "6 7"
EndSection
______________________________________________________________________
The IntelliMouse Explorer has 5 buttons, thus, you should give "7" to
the Buttons option if you want to map the wheel movement to buttons (6
and 7). With this configuration, the correspondence between the
buttons and button numbers will be as follows:
Physical Buttons Reported as:
------------------------------------
1 Left Button Button 1
2 Wheel Button Button 2
3 Right Button Button 3
4 Side Button 1 Button 4
5 Side Button 2 Button 5
6 Wheel Negative Move Button 6
7 Wheel Positive Move Button 7
You can change button number assignment using xmodmap AFTER you
started the X server with the above configuration.
xmodmap -e "pointer = 1 2 3 4 7 5 6"
The above command will moves the side button 2 to the button 7 and
make the wheel movement reported as the button 5 and 6. See the table
below.
Physical Buttons Reported as:
------------------------------------
1 Left Button Button 1
2 Wheel Button Button 2
3 Right Button Button 3
4 Side Button 1 Button 4
5 Side Button 2 Button 7
6 Wheel Negative Move Button 5
7 Wheel Positive Move Button 6
For the A4 Tech WinEasy mouse which has two wheels and 3 buttons, you
may have the following InputDevice section.

The Kensington Expert mouse is really a trackball. It has 4 buttons
arranged in a rectangle around the ball.

Identifier "DLB"
Driver "mouse"

Option "Buttons" "3"
Option "Emulate3Buttons"
Option "Device" "/dev/mouse"
Option "DragLockButtons" "2 1 4 3"
EndSection
______________________________________________________________________
In this example, button 2 is a drag lock button for button number 1,
and button 4 is a drag lock button for button 3. Since button 2 is
above button 1 and button 4 is above button 3 in the layout of this
trackball, this is reasonable.
Because button 2 is being used as a drag lock, it can not be used as
an ordinary button. However, it can be activated by using the
"Emulate3Buttons" feature. However, some people my be unable to press
two buttons at the same time. They may prefer the following
InputDevice section which defines button 4 as a master drag lock
button, and leaves button 2 free for ordinary use.
