mouse is an Xorg input driver for mice. The driver supports
most available mouse types and interfaces. USB mice are only supported
on some OSs, and the level of support for PS/2 mice depends on the OS.
The
mouse driver functions as a pointer input device, and may be used as the
X server's core pointer. Multiple mice are supported by multiple instances
of this driver.
There is a detailed list of hardware that
the mouse driver supports in the README.mouse document. This can be found
in /usr/X11R6/lib/X11/doc/, or online at http://www.x.org/current/mouse.html.
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.
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.mouse
document 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" platform specifies that protocol auto-detection
should be attempted. There is no default protocol setting, and specifying
this option is mandatory.
- 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.
- 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: off
- 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.
- 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. 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:
"4 5".
- 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. Default: "4 5 6 7".
- Option
"ButtonMapping" "N1 N2 [...]"
- Specifies how physical mouse buttons are mapped
to logical buttons. Physcial 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-to-1 mapping.
- 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
"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.
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. 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.
