DESCRIPTION
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 multi-
ple instances of this driver.
SUPPORTED HARDWARE
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.xfree86.org/cur-
rent/mouse.html.
CONFIGURATION DETAILS
Please refer to xorg.conf(4) 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 sup-
ports. 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, Mouse-
Man, MMHitTab, GlidePoint, IntelliMouse, ThinkingMouse,
ValuMouseScroll, AceCad, PS/2, ImPS/2, ExplorerPS/2, Think-
ingMousePS/2, MouseManPlusPS/2, GlidePointPS/2, Net-
MousePS/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 num-
ber 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 emulat-
ing 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 emula-
tion 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, Emulate-
WheelInertia, XAxisMapping, and YAxisMapping options below.
Default: off.
Option "EmulateWheelButton" "integer"
Specifies which button must be held down to enable wheel emula-
tion mode. While this button is down, X and/or Y pointer move-
ment 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 neg-
ative X axis motion and button number N2 is mapped to the posi-
tive 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 neg-
ative Y axis motion and button number N2 is mapped to the posi-
tive 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 nega-
tive Z axis motion and button number N2 is mapped to the posi-
tive Z axis motion. For mice with two wheels, four button num-
bers 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 sec-
ond. 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" indi-
cating 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 param-
eters for serial port communication, but they are not documented here
because the driver sets them correctly for each mouse protocol type.
