-!!!1. Introduction
-
-This mini-HOWTO was created by gathering the information already available on
-the internet, in newsgroups and other HOWTOs. I needed to hook up an USB mouse
-in addition to the built-in trackpoint on my Thinkpad laptop.
-
-
-
-Examples in this mini-HOWTO pertain to my particular hardware configuration,
-which is PS/2 mouse as a primary pointer and USB wheel mouse as an additional
-one. It should be pretty straightforward to implement another combination, say,
-a PS/2 and a serial mice. Two things that would have to be changed are the
-''mouse protocol'' and the ''mouse device''. Wherever
-possible, I try to provide appropriate examle.
-
-
-
-The instructions for X are divided into two sections, one fro XFree version 3 and one
-for XFree 4. The format of the XF86Config file has significantly changed between
-versions and requires slightly different approach. In XFree 3.x, the second
-mouse has to appear in an ''Xinput'' section, which has
-slightly different syntax than the regular ''Pointer'' section.
-In XFree 4.x, it's just another pointer.

-!!!3. Mouse Protocols
-
-Two most important parameters in the XF86Config file, ones that are crucial to the mouse working properly are the ''Protocol'' and ''Device''.
-
-
-
-As far as ''Protocol'' is concerned, it seems that
-''gpm'' uses compatible protocol names, so please look there
-for the detailed information. Here is the excerpt taken from the gpm info page
-(just the few most commont types):
-
-
-__Table 1. Most Common Mouse Protocols in X__
-
-
-Protocol
-
-|Name | Description
-|Microsoft | Standard Microsoft mice.
-|!MouseSystems | This is the standard protocol for three-button serial devices.
-| MMSeries | Title says it all. This mouse decoder accepts standard serial options, although they should not be needed.
-| Logitech | This is the protocol used by old serial Logitech mice.
-| !BusMouse | Some bus devices use this protocol, including those produced by Logitech.
-| PS/2 | The protocol used by most busmice.
-| IMPS/2 | IntelliMouse on the ps/2 port. ''Also works with USB mice''
-
-----
-!!!4. XFree 3.x
-
-In XFree 3.x, additional pointing devices, like mice or tablets, are defined
-through the use of an ''Xinput'' section. The primary mouse is
-defined as usual:
-
-Section "Pointer"
-Protocol "PS/2"
-Device "/dev/mouse"
-!EndSection
-In the case above, it's a regular three-button PS/2 mouse, which works for the
-trackpoint as well. Now, for the USB mouse:
-
- Section "Xinput"
-!SubSection "Mouse"
-!DeviceName "USB Mice"
-Protocol "IMPS/2"
-ZAxisMapping 4 5
-Port "/dev/input/mice"
-Alwayscore
-!EndSubSection
-!EndSection
-My mouse is a wheel mouse, thus the protocol is ''IMPS/2''. ZAxisMapping line is also needed for the wheel to work.
-I also want the mouse to always work alongside the other one, and this is achieved
-through the ''!AlwaysCore'' option. If. for example, this was
-a serial mouse, the ''Port'' would read
-__"/dev/ttyS0"__ for __COM1__.
-
-----
-!!!5. XFree 4.x
-
-With XFree 4.x the task is even easier. First, the primary mouse, usually present in the config file already:
-
-Section "!InputDevice"
-Identifier "Mouse0"
-Driver "mouse"
-Option "Device" "/dev/mouse"
-Option "Protocol" "PS/2"
-Option "Emulate3Buttons" "off"
-Option "ZAxisMapping" "4 5"
-!EndSection
-To add another mouse just copy the above section and modify it, so that it reads:
-
-Section "!InputDevice"
-Identifier "Mouse1"
-Driver "mouse"
-Option "Device" "/dev/input/mice"
-Option "Protocol" "IMPS/2"
-Option "Emulate3Buttons" "off"
-Option "ZAxisMapping" "4 5"
-!EndSection
-Well, this way you can define as many additional pointers as you wish, and the same applies to joysticks and tablets.
-
-
-
-To make both mice work together, there's one more change to be made to the XF86Config file.
-There is a section called ''!ServerLayout'' where all the components are specified. Here's how it looks ''before'' adding a second mouse:
-
-Section "!ServerLayout"
-Identifier "XFree86 Configured"
-Screen 0 "Screen0" 0
-!InputDevice "Mouse0" "!CorePointer"
-!InputDevice "Keyboard0" "!CoreKeyboard"
-!EndSection
-And ''after'' adding the second mouse:
-
-Section "!ServerLayout"
-Identifier "XFree86 Configured"
-Screen 0 "Screen0" 0
-!InputDevice "Mouse0" "!CorePointer"
-!InputDevice "Mouse1" "!AlwaysCore"
-!InputDevice "Keyboard0" "!CoreKeyboard"
-!EndSection

-!!!6. Alternatives
-
-Another way to use two (or more) mice at the same time time is to use a program such as ''!MultiMouse'' by Takashi Manabe. It's a daemon multiplexing several mice and making them available through the special device /dev/mumse as a !MouseSystems compatible mouse.
-
-
-
- According to the author: "This program allows you to use multiple mice at the same time. This program is developed for a subnote user who want to use both a pre-mounted pointing device and a external serial mouse."
-
-
-
-I'm not sure if the program supports second mouse other than serial, but the advantage is that the second mouse works in console mode too. __!MultiMouse__ can be found at Sunsite (sunsite.unc.edu /pub/Linux/system/Misc) and Tucows (www.tucows.com Linux Console -b Utilities).
