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 /tmp/Xorg-KEM/lib/X11/doc/, or online at http://www.xfree86.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, 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.
- 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: 50.
- 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: no 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.
