DESCRIPTION
mouse is an Xorg input driver for mice. The driver supports most
available mouse types and interfaces, though the level of support for types of
mice depends on the OS.
The
mouse driver functions as a pointer input device. Multiple mice are
supported by multiple instances of this driver.
SUPPORTED HARDWARE
- USB mouse
- USB (Universal Serial Bus) ports are present on most modern
computers. Several devices can be plugged into this bus, including mice
and keyboards. Support for USB mice is platform specific.
- PS/2 mouse
- 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.
- Serial mouse
- There have been numerous serial mouse models from a number
of manufacturers. 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. This driver 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 older video cards, notably those from ATI, and
integrated I/O cards may also have a bus mouse connector.
The interface type of the mouse can be determined by looking at the connector of
the mouse. USB mice have a thin rectangular connector. PS/2 mice are equipped
with a small, round DIN 6-pin connector. Serial mouse have a D-Sub female 9-
or 25-pin connector. Bus mice have either a D-Sub male 9-pin connector or a
round DIN 9-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.
CONFIGURATION DETAILS
Depending on the X server version in use, input device options may be set in
either a xorg.conf file, an xorg.conf.d snippet or in the configuration files
read by the Hardware Abstraction Layer (HAL) daemon, hald(1).
Please refer to xorg.conf(5) 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.
The driver can auto-detect the mouse type on some platforms. On some platforms
this is limited to plug and play serial mice, and on some the auto-detection
works for any mouse that the OS's kernel driver supports. On others, it is
always necessary to specify the mouse protocol in the config file. The
README document provided with this driver contains some detailed
information about this.
The following driver
Options are supported:
- Option "Protocol"
"string"
- Specify the mouse protocol. Valid protocol types
include:
Auto, Microsoft, MouseSystems, MMSeries,
Logitech, MouseMan, MMHitTab, GlidePoint, IntelliMouse, ThinkingMouse,
ValuMouseScroll, AceCad, PS/2, ImPS/2, ExplorerPS/2, ThinkingMousePS/2,
MouseManPlusPS/2, GlidePointPS/2, NetMousePS/2, NetScrollPS/2, BusMouse,
SysMouse, WSMouse, USB, VUID, Xqueue.
Not all protocols are supported on all
platforms. The "Auto" protocol specifies that protocol
auto-detection should be attempted. The default protocol setting is
platform-specific.
- Option "Device"
"string"
- Specifies the device through which the mouse can be
accessed. A common setting is "/dev/mouse", which is often a
symbolic link to the real device. This option is mandatory, and there is
no default setting. The driver may however attempt to probe some default
devices if this option is missing. Property: "Device Node"
(read-only).
- Option "Buttons"
"integer"
- Specifies the number of mouse buttons. In cases where the
number of buttons cannot be auto-detected, the default value is 3. The
maximum number is 24.
- Option "Emulate3Buttons"
"boolean"
- Enable/disable the emulation of the third (middle) mouse
button for mice which only have two physical buttons. The third button is
emulated by pressing both buttons simultaneously. Default: on, until a
press of a physical button 3 is detected. Property: "Mouse Middle
Button Emulation"
- Option "Emulate3Timeout"
"integer"
- Sets the timeout (in milliseconds) that the driver waits
before deciding if two buttons where pressed "simultaneously"
when 3 button emulation is enabled. Default: 50. Property: "Mouse
Middle Button Timeout"
- Option "ChordMiddle"
"boolean"
- Enable/disable handling of mice that send left+right events
when the middle button is used. Default: off.
- Option "EmulateWheel"
"boolean"
- Enable/disable "wheel" emulation. Wheel emulation
means emulating button press/release events when the mouse is moved while
a specific real button is pressed. Wheel button events (typically buttons
4 and 5) are usually used for scrolling. Wheel emulation is useful for
getting wheel-like behaviour with trackballs. It can also be useful for
mice with 4 or more buttons but no wheel. See the description of the
EmulateWheelButton, EmulateWheelInertia,
XAxisMapping, and YAxisMapping options below. Default:
off.
- Option "EmulateWheelButton"
"integer"
- Specifies which button must be held down to enable wheel
emulation mode. While this button is down, X and/or Y pointer movement
will generate button press/release events as specified for the
XAxisMapping and YAxisMapping settings. If set to 0, no
button is required and any motion of the device is converted into wheel
events. Default: 4.
- Option "EmulateWheelInertia"
"integer"
- Specifies how far (in pixels) the pointer must move to
generate button press/release events in wheel emulation mode. Default:
10.
- Option "EmulateWheelTimeout"
"integer"
- Specifies the time in milliseconds the
EmulateWheelButton must be pressed before wheel emulation is
started. If the EmulateWheelButton is released before this timeout,
the original button press/release event is sent. Default: 200.
- Option "XAxisMapping" "N1
N2"
- Specifies which buttons are mapped to motion in the X
direction in wheel emulation mode. Button number N1 is mapped to
the negative X axis motion and button number N2 is mapped to the
positive X axis motion. Default: no mapping.
- Option "YAxisMapping" "N1
N2"
- Specifies which buttons are mapped to motion in the Y
direction in wheel emulation mode. Button number N1 is mapped to
the negative Y axis motion and button number N2 is mapped to the
positive Y axis motion. Default: no mapping.
- Option "ZAxisMapping" "X"
- Option "ZAxisMapping" "Y"
- Option "ZAxisMapping" "N1
N2"
- Option "ZAxisMapping" "N1 N2 N3
N4"
- Set the mapping for the Z axis (wheel) motion to buttons or
another axis (X or Y). Button number N1 is mapped to
the negative Z axis motion and button number N2 is mapped to the
positive Z axis motion. For mice with two wheels, four button numbers can
be specified, with the negative and positive motion of the second wheel
mapped respectively to buttons number N3 and N4. Note that
the protocols for mice with one and two wheels can be different and the
driver may not be able to autodetect it. Default: "4 5".
- Option "ButtonMapping" "N1 N2
[...]"
- Specifies how physical mouse buttons are mapped to logical
buttons. Physical button 1 is mapped to logical button N1, physical
button 2 to N2, and so forth. This enables the use of physical
buttons that are obscured by ZAxisMapping.
Default: "1 2 3 8 9 10 ...".
- Option "FlipXY"
"boolean"
- Enable/disable swapping the X and Y axes. This
transformation is applied after the InvX, InvY and
AngleOffset transformations. Default: off.
- Option "InvX"
"boolean"
- Invert the X axis. Default: off.
- Option "InvY"
"boolean"
- Invert the Y axis. Default: off.
- Option "AngleOffset"
"integer"
- Specify a clockwise angular offset (in degrees) to apply to
the pointer motion. This transformation is applied before the
FlipXY, InvX and InvY transformations. Default:
0.
- Option "SampleRate"
"integer"
- Sets the number of motion/button events the mouse sends per
second. Setting this is only supported for some mice, including some
Logitech mice and some PS/2 mice on some platforms. Default: whatever the
mouse is already set to.
- Option "Resolution"
"integer"
- Sets the resolution of the device in counts per inch.
Setting this is only supported for some mice, including some PS/2 mice on
some platforms. Default: whatever the mouse is already set to.
- Option "Sensitivity"
"float"
- Mouse movements are multiplied by this float before being
processed. Use this mechanism to slow down high resolution mice. Because
values bigger than 1.0 will result in not all pixels on the screen being
accessible, you should better use mouse acceleration (see man xset)
for speeding up low resolution mice. Default: 1.0
- Option "DragLockButtons" "L1 B2 L3
B4"
- Sets "drag lock buttons" that simulate holding a
button down, so that low dexterity people do not have to hold a button
down at the same time they move a mouse cursor. Button numbers occur in
pairs, with the lock button number occurring first, followed by the button
number that is the target of the lock button.
- Option "DragLockButtons"
"M1"
- Sets a "master drag lock button" that acts as a
"Meta Key" indicating that the next button pressed is to be
"drag locked".
- Option "ClearDTR"
"boolean"
- Enable/disable clearing the DTR line on the serial port
used by the mouse. Some dual-protocol mice require the DTR line to be
cleared to operate in the non-default protocol. This option is for serial
mice only and is handled by the X server. Default: off.
- Option "ClearRTS"
"boolean"
- Enable/disable clearing the RTS line on the serial port
used by the mouse. Some dual-protocol mice require the RTS line to be
cleared to operate in the non-default protocol. This option is for serial
mice only and is handled by the X server. Default: off.
- Option "BaudRate"
"integer"
- Set the baud rate to use for communicating with a serial
mouse. This option should rarely be required because the default is
correct for almost all situations. Valid values include: 300, 1200, 2400,
4800, 9600, 19200. Default: 1200.
There are some other options that may be used to control various parameters for
serial port communication, but they are not documented here because the driver
sets them correctly for each mouse protocol type.
