You may check your mouse with the mev command from the GPM package.
Trackpad, Touchpad, are used with the majority of current laptops
Trackball, e.g. COMPAQ LTE
Pop-up-Mouse, e.g. HP OmniBook 800
Trackpoint, Mouse-Pin, e.g. IBM™ ThinkPad and Toshiba laptops
3 Button Mice, e.g. IBM™ Thinkpads at least the 600s and some COMPAQ models e.g. Armada M700. I have heard rumor about a 3 button mouse for Texas Instruments Travelmates, but couldn't verify this yet.
Touchscreen, e.g. some Fujitsu-Siemens laptops, TabletPCs and PDAs
Most of the mice used in laptops are PS/2 mice (actually I
don't know one with another mouse protocol). You may
communicate with the PS/2 mouse through
/dev/psmouse. If you use X Windows
this device and the protocol has to be set in
/etc/X11/XF86Config. In earlier
releases, sometimes the GPM mouse manager and X Windows had
trouble sharing a mouse when enabled at the same time. But
as far as I know this is no problem anymore for the latest
/etc/X11/XF86Configfor XFree86 3.x:
Section "Pointer" ... Emulate3Buttons Emulate3Timeout 100 ... EndSection

Usually a touchpad works with the PS/2 mouse device
/dev/psaux and the PS/2 protocol (for GPM and X11,
for X11 it seems also worth to check the GlidePointPS/2 protocol).
The Synaptics TouchPad driver has the following functions (some functions require features from the touchpad that must be present, multifinger taps for example):
Movement with adjustable, non-linear acceleration and speed (Options: MinSpeed, MaxSpeed, AccelFactor)
Button events through short touching of the touchpad (Options: MaxTapTime, MaxTapMove)
Double-Button events through double short touching of the touchpad
Dragging through short touching and holding down the finger on the touchpad
Middle and right button events on the upper and lower corner of the touchpad (Option: Edges)
Scrolling (button four and five events) through moving the finger on the right side of the touchpad (Options: Edges, VertScrollDelta)
The up/down button sends button four/five events
Adjustable finger detection (Option: Finger)
Ext Mouse repeater support - Alpha! (Option: Repeater)
Multifinger taps: two finger for middle button and three finger for right button events
Online configuration through shared-memory (in development) (Option: SHMConfig)
The synclient command is provived with the driver sources (note it's not included in SuSE Linux, at least not until 9.3). The command queries and modifies the Synaptics TouchPad driver parameters on the fly.
Tipping with one, two or three fingers on the touchpad simultaneously results in pressing the left, middle and respectively the right mouse-button.
There is also another touchpad driver available. The Synaptics Touchpad Linux Driver - tpconfig supports pointing devices used in notebooks by Acer, Compaq, Dell, Gateway, Olivetti, Texas Instruments, Winbook, and others.
Dell and Sony have started incorporating a touchpad, touchstick from ALPS. They are in at least the Dell Latitude CPx and the Sony VAIO laptop lines. Maintainer Bruce Kall writes: "tpconfig does NOT support them at this time, but I am in the process of getting the API from ALPS and will be incorporating this in the next version of tpconfig. The Dell's also incorporate the ALPS GlideStick in the middle of the keyboard (like the stick pointer in some of the IBM Thinkpads). I also intend to support the disabling of "tapping" the GlideStick as well. Tapping of the touchpad/touchsticks drives me crazy, I'm not sure about you (causes the "selection" of things on the screen when you don't want to)!"
tpconfig is a command-line utility to set options on Synaptics Touchpad and (now) ALPS Glidepad/ Stickpointers. Most people primarily use it to turn off the "tap mode" on laptop touchpads.
How to use tpconfig: tpconfig is currently supported as a command-line configuration tool. The PS/2 port does not currently support sharing. Therefore the tpconfig utility will not work while any other mouse driver is loaded (e.g. gpm). This also means that you cannot use tpconfig while X Windows is running. The suggested use of tpconfig is to run it from a startup script before gpm is started.
Not all touchpads are being from Synaptics, e.g some Gateways incorporate an EZ-Pad (Registered TM) and there might be other brands. The TPREV.EXE utility will verify you have a Synaptics touchpad.
The recent gpm package (version >=1.8, maybe earlier versions contain touchpad support, too) includes the above mentioned Synaptics touchpad device driver. This device driver has been developed by H. Davies <hdavies_AT_ameritech.net>. Instead of using the PS/2 compatibility mode of touchpad devices, you can now use native touchpad mode with some pretty impressive features.
In addition to translating finger motion into mouse motion and supporting the buttons, this support currently has several features (from the README):
a "tap" on the TouchPad causes a left mouse click
a "tap" followed quickly by a finger motion causes a left button drag type action.
a "tap" in one of the corners causes an action the default configuration is upper right causes middle mouse click and lower right causes right mouse click
more pressure on the touch pad speeds the motion of the cursor
a "tap" with a motion component (default > 2mm) initiates a toss and catch sequence. This is terminated by a finger touch on the pad (the toss also ends after 1 sec since that is the idle timeout period for the touchpad).
if the finger moves close to an edge then the mouse motion will be continued in that direction so that you don't need to pick up your finger and start moving again. This continued motion is pressure sensitive (more pressure is faster motion).
These features can be enabled/disabled and many of them have time and speed parameters which can be adjusted to the taste of the user.
It seems gpm is best known as a console biased tool.
This is true, but you may use it as an X11 input device.
gpm is used as a repeater device. In this way you can
use both the built-in synaptics touchpad with all the features and at
the same time a serial mouse (with three buttons). This all works
smoothly together. X11 reads the mouse events from a named pipe
/dev/gpmdata in a protocol it understands, which in
my case is Mouse-Systems-Compatible (5bytes). Most
3-button mice use the default protocol. So a simple reconfiguration in
XF86Config is all that is required, after starting
gpm in an appropriate way, of course.
gpm could be started on your laptop with the
following arguments : /usr/bin/gpm -t synps2 -M -t ms -m
/dev/ttyS0 . Both touchpad and serial mouse work in console
and X11 mode. You do have to create the named pipe
Tapping with two fingers simultaneously to simulate a middle mouse button works on Logitech touchpads used in a few machines.

The only modern laptops I know which include a touchscreen are the Fujitsu Biblo 112/142 (aka MC 30) and the Palmax PD 1000/1100 (aka IPC 1000/1100).
The latest version of the Linux Compaq Concerto Pen Driver is available from Joe Pfeiffer's home page.
A current survey of drivers you may find at my page Touchscreen Laptops and Linux .
IBM and Toshiba laptops currently come with a pen devices instead of a mousepad or trackball.
It needs some time to get used to this kind of pointer device. It may help to rest your palm at the front rest. Also it's recommended to reduce the mouse speed.
For better handling, e.g. with a 3 button mouse you may use an external mouse. This is usually a serial mouse or a PS/2 mouse, or in our days a USB mouse, appropriate to the port your laptop offers. Usually this is no problem. The only thing I currently don't know a solution for is the automagic detection of a newly plugged in mouse from X11. To get it work you have to restart your X server.
For PS/2 ports there are so called Y-Cable available, which make it possible to use external mouse and external keyboard at the same time if your laptop supports this feature.
Don't plug in the external mouse while powered up. If you have separate mouse and keyboard ports, make sure you plug the mouse in the mouse port and the keyboard in the keyboard port. If you don't, you may have to do a hard reboot of the laptop to get it to recover.
Imwheel makes the wheel of your Intellimouse (and other wheel and stick mice) work in Linux/X11 to scroll windows up and down, or send keys to programs. It runs in the background as a daemon and requires little reconfiguration of the XWindows setup. 4 or more button mice and Alps Glidepad 'Taps' may also be used. imwheel includes a modified gpm for an alternate method of wheel input.
This part is taken from The Linux USB Sub-System by Brad Hards.
There are two options for using a USB mouse or a USB keyboard - the standalone Boot Protocol way and the full featured HID driver way. The Boot Protocol way is generally inferior, and this document describes the full featured way. The Boot Protocol way may be appropriate for embedded systems and other systems with resource constraints and no real need for the full keyboard and mouse capabilities.
It is important to remember that the HID driver handles those devices (or actually those interfaces on each device) that claim to comply with the Human Interface Device (HID) specification. However the HID specification doesn't say anything about what the HID driver should do with information received from a HID device, or where the information that is sent to a device comes from, since this is obviously dependent on what the device is supposed to be doing, and what the operating system is. Linux (at the operating system kernel level) supports four interfaces to a HID device - keyboard, mouse, joystick and a generic interface, known as the event interface.
In the kernel configuration stage, you need to turn on
USB Human Interface Device (HID) support and Mouse
Support Do not turn on USB HIDBP Mouse support.
Perform the normal kernel rebuild and installation steps. If you are
installing as modules, you need to load the
Plug in a USB mouse and check that your mouse has
been correctly sensed by the kernel. If you don't have a kernel message,
look for the changes to
Since USB supports multiple identical devices, you can have multiple mice plugged in. You can get each mouse seperately, or you can get them all mixed together. You almost always want the mixed version, and that is what will be used together. You need to set up a device node entry for the mixed mice. It is customary to create the entries for this device in the /dev/input/ directory.
mkdir /dev/input mknod /dev/input/mice c 13 63
If you are unsure whether you are configuring the right mouse device, use cat /dev/input/mice (or other appropriate devices names). In case you do this for the correct mouse, you should see some bizarre looking characters as you move the mouse or click any of the buttons.
If you want to use the mouse under X, you have various options. Which one you select is dependent on what version of XFree86 you are using and whether you are using only USB for your mouse (or mice), or whether you want to use a USB mouse and some other kind of pointer device.
You need to edit the
XF86Config file (usually
Section "InputDevice" Identifier "USB Mice" Driver "mouse" Option "Protocol" "IMPS/2" Option "Device" "/dev/input/mice" EndSection
Section "InputDevice" Identifier "USB Mice" Driver "mouse" Option "Protocol" "IMPS/2" Option "Device" "/dev/input/mice" Option "ZAxisMapping" "4 5" Option "Buttons" "5" EndSection
Consult the current XFree86 documentation for a detailed explaination and more examples.

Section "Xinput" SubSection "Mouse" DeviceName "USB Mice" Protocol "IMPS/2" Port "/dev/input/mice" AlwaysCore EndSubSection EndSection
Restart the X server. If you don't have any mouse support at this point, remember that Ctrl-Alt-F1 will get you a virtual terminal that you can use to kill the X server and start debugging from the error messages.
If you want to use the mouse under gpm, run (or kill and restart if it
is already running) gpm with the following options. gpm -m
/dev/input/mice -t imps2 (as superuser). You can make
this the default if you edit the initialisation files. These are
typically named something like rc.d and are in
/etc/rc.d/ on RedHat distributions.
If you have both a USB mouse (or
USB mice) and some other kind of pointer device, you
may wish to use gpm in repeater mode. If you have a PS/2 mouse on
/dev/psaux and a USB mouse (or USB
mice) on /dev/input/mice, then the following gpm
command would probably be appropriate: gpm -m /dev/input/mice
-t imps2 -M -m /dev/psaux -t ps2 -R imps2. Note that this will
make the output appear on
/dev/gpmdata, which is a
FIFO and does not need to be created in advance. You can use this as the
mouse "device" to non-X programs, and both mice will work together.

The gpm contains a driver for the Twiddler device at the serial port. For information about the Twiddler see Handykey Corporation .
PowerBooks have a trackpad and only one button, although you can plug in external multi-button USB mice. The usual thing is to map a couple of keys on the keyboard to the middle and right mouse buttons; your Linux distribution should come with instructions on how to configure this (it's not specific to laptops, as all Apple mice are single-button).
If you are using the Xpmac server, the default is option-1 and option-2, and you can change this by passing -middlekey <keycode> -rightkey <keycode> arguments to Xpmac, and -nooptionmouse if you don't want the option key to be needed.
If you are using XFree86, you pass adb_buttons=<middlekey>,<rightkey> kernel arguments (no option is required). I use adb_buttons=58,55 to map the option and Apple/command keys (which are little-used in Linux); use e.g. xev to find out the keycode for a given key.
