The mouse daemon listens to the specified port for mouse data, interprets and then passes it via ioctls to the console driver. The mouse daemon reports translation movement, button press/release events and movement of the roller or the wheel if available. The roller/wheel movement is reported as "Z" axis movement.
The console driver will display the mouse pointer on the screen and provide cut and paste functions if the mouse pointer is enabled in the virtual console via vidcontrol(1). If sysmouse(4) is opened by the user program, the console driver also passes the mouse data to the device so that the user program will see it.
If the mouse daemon receives the signal SIGHUP, it will reopen the mouse port and reinitialize itself. Useful if the mouse is attached/detached while the system is suspended.
If the mouse daemon receives the signal SIGUSR1, it will stop passing mouse events. Sending the signal SIGUSR1 again will resume passing mouse events. Useful if your typing on a laptop is interrupted by accidentally touching the mouse pad.
The following options are available:
|Emulate the third (middle) button for 2-button mice. It is emulated by pressing the left and right physical buttons simultaneously.|
|Set double click speed as the maximum interval in msec between button clicks. Without this option, the default value of 500 msec will be assumed. This option will have effect only on the cut and paste operations in the text mode console. The user program which is reading mouse data via sysmouse(4) will not be affected.|
|Lower DTR on the serial port. This option is valid only if mousesystems is selected as the protocol type. The DTR line may need to be dropped for a 3-button mouse to operate in the mousesystems mode.|

is enabled, the
Apply exponential (dynamic) acceleration to mouse movements:
the faster you move the mouse, the more it will be accelerated.
That means that small mouse movements are not accelerated,
so they are still very accurate, while a faster movement will
drive the pointer quickly across the screen.
The exp value specifies the exponent, which is basically the amount of acceleration. Useful values are in the range 1.1 to 2.0, but it depends on your mouse hardware and your personal preference. A value of 1.0 means no exponential acceleration. A value of 2.0 means squared acceleration (i.e. if you move the mouse twice as fast, the pointer will move four times as fast on the screen). Values beyond 2.0 are possible but not recommended. A good value to start is probably 1.5.
The optional offset value specifies the distance at which the acceleration begins. The default is 1.0, which means that the acceleration is applied to movements larger than one unit. If you specify a larger value, it takes more speed for the acceleration to kick in, i.e. the speed range for small and accurate movements is wider. Usually the default should be sufficient, but if you're not satisfied with the behaviour, try a value of 2.0.
Note that the

This is a linear acceleration only.

Also note that if your mouse is attached to the PS/2 mouse port, you should always choose auto or ps/2, regardless of the brand and model of the mouse. Likewise, if your mouse is attached to the bus mouse port, choose auto or busmouse. Serial mouse protocols will not work with these mice.
For the USB mouse, the protocol must be auto. No other protocol will work with the USB mouse.
Valid types for this option are listed below.
For the serial mouse:
|microsoft||Microsoft serial mouse protocol. Most 2-button serial mice use this protocol.|
|intellimouse||Microsoft IntelliMouse protocol. Genius NetMouse, ASCII Mie Mouse, Logitech MouseMan+ and FirstMouse+ use this protocol too. Other mice with a roller/wheel may be compatible with this protocol.|
|mousesystems||MouseSystems 5-byte protocol. 3-button mice may use this protocol.|
|mmseries||MM Series mouse protocol.|
|logitech||Logitech mouse protocol. Note that this is for old Logitech models. mouseman or intellimouse should be specified for newer models.|
|mouseman||Logitech MouseMan and TrackMan protocol. Some 3-button mice may be compatible with this protocol. Note that MouseMan+ and FirstMouse+ use intellimouse protocol rather than this one.|
|glidepoint||ALPS GlidePoint protocol.|
|thinkingmouse||Kensington ThinkingMouse protocol.|
|mmhitab||Hitachi tablet protocol.|
|kidspad||Genius Kidspad and Easypad protocol.|
|versapad||Interlink VersaPad protocol.|
|gtco_digipad||GTCO Digipad protocol.|
For the bus and InPort mouse:
|busmouse||This is the only protocol type available for the bus and InPort mouse and should be specified for any bus mice and InPort mice, regardless of the brand.|
For the PS/2 mouse:
|ps/2||This is the only protocol type available for the PS/2 mouse and should be specified for any PS/2 mice, regardless of the brand.|
For the USB mouse, auto is the only protocol type available for the USB mouse and should be specified for any USB mice, regardless of the brand.
Make the physical button
act as the wheel mode button.
While this button is pressed, X and Y axis movement is reported to be zero
and the Y axis movement is mapped to Z axis.
You may further map the Z axis movement to virtual buttons by the
| ||Map Z axis (roller/wheel) movement to another axis or to virtual buttons. Valid target maybe:|
|X or Y axis movement will be reported when the Z axis movement is detected.|
|N||Report down events for the virtual buttons N and N+1 respectively when negative and positive Z axis movement is detected. There do not need to be physical buttons N and N+1. Note that mapping to logical buttons is carried out after mapping from the Z axis movement to the virtual buttons is done.|
|N1 N2||Report down events for the virtual buttons N1 and N2 respectively when negative and positive Z axis movement is detected.|
|N1 N2 N3 N4||
This is useful for the mouse with two wheels of which
the second wheel is used to generate horizontal scroll action,
and for 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 will not be detected.
Note that horizontal movement or second roller/wheel movement may not always be detected, because there appears to be no accepted standard as to how it is encoded.
Note also that 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.
The next thing to decide is a port to use for the given interface. For the bus, InPort and PS/2 mice, there is little choice: the bus and InPort mice always use /dev/mse0, and the PS/2 mouse is always at /dev/psm0. There may be more than one serial port to which the serial mouse can be attached. Many people often assign the first, built-in serial port /dev/cuau0 to the mouse. You can attach multiple USB mice to your system or to your USB hub. They are accessible as /dev/ums0, /dev/ums1, and so on.
You may want to create a symbolic link /dev/mouse pointing to the real port to which the mouse is connected, so that you can easily distinguish which is your "mouse" port later.
The next step is to guess the appropriate protocol type for the mouse.

Assign the physical button 3 (right button) to the logical button 1 (logical left) and the physical button 1 (left) to the logical button 3 (logical right). This will effectively swap the left and right buttons.
moused -p /dev/mouse -t intellimouse -z 4
Report negative Z axis movement (i.e., mouse wheel) as the button 4 pressed and positive Z axis movement (i.e., mouse wheel) as the button 5 pressed.
If you add

to your /usr/local/etc/sudoers file, and bind
killall -USR1 moused
to a key in your window manager, you can suspend mouse events on your laptop if you keep brushing over the mouse pad while typing.
Cut and paste functions in the virtual console assume that there
are three buttons on the mouse.
The logical button 1 (logical left) selects a region of text in the
console and copies it to the cut buffer.
The logical button 3 (logical right) extends the selected region.
The logical button 2 (logical middle) pastes the selected text
at the text cursor position.
If the mouse has only two buttons, the middle, `paste' button
is not available.
To obtain the paste function, use the
