Before using the xorgconfig program
to set up mouse configuration, you must identify the interface type,
the device name and the protocol type of your mouse.
Blindly trying every possible combination of mouse settings
will lead you nowhere.
The first thing you need to know is the interface type of the mouse you are going to use. It can be determined by looking at the connector of the mouse. The serial mouse has a D-Sub female 9- or 25-pin connector. The bus mice have either a D-Sub male 9-pin connector or a round DIN 9-pin connector. The PS/2 mouse is equipped with a small, round DIN 6-pin connector. Some mice come with adapters with which the connector can be converted to another. If you are to use such an adapter, remember that the connector at the very end of the mouse/adapter pair is what matters.
The next thing to decide is a device node to use for the given interface. For the bus and PS/2 mice, there is little choice; your OS most possibly offers just one device node each for the bus mouse and PS/2 mouse. There may be more than one serial port to which the serial mouse can be attached.
The next step is to guess the appropriate protocol type for the mouse. The X server may be able to select a protocol type for the given mouse automatically in some cases. Otherwise, the user has to choose one manually. Follow the guidelines below.
The bus and InPort mice always use "BusMouse"
protocol regardless of the brand of the mouse.
Some OSs may allow you to specify "Auto" as the
protocol type for the bus mouse.
The "PS/2" protocol should always be tried first for the PS/2 mouse
regardless of the brand of the mouse.
Any PS/2 mouse should work with this protocol type, although
wheels and other additional features are unavailable in the
X server.
After verifying the mouse works with this protocol,
you may choose to specify one of "xxxPS/2" protocols so that
extra features are made available in the X server.
However, support for these PS/2 mice assumes certain behavior of
the underlying OS and may not always work as expected.
Support for some PS/2 mouse models may be disabled all together
for some OS platforms for this reason.
Some OSs may allow you to specify "Auto" as the
protocol type for the PS/2 mouse and the X server will automatically
adjust itself.
The server supports a wide range of mice, both old and new. If your mouse is of a relatively new model, it may conform to the PnP COM device specification and the X server may be able to detect an appropriate protocol type for the mouse automatically.
Specify "Auto" as the protocol type and start the X server.
If the mouse is not a PnP mouse, or the X server cannot determine
a suitable protocol type, the server will print the following
error message and abort.
<mousename>: cannot determine the mouse protocol
If the X server generates the above error message, you need to manually specify a protocol type for your mouse. Choose one from the following list:
GlidePointIntelliMouseLogitechMicrosoftMMHittabMMSeriesMouseManMouseSystemsThinkingMouseWhen you choose, keep in mind the following rule of thumb:
"Logitech" protocol is for old serial mouse models
from Logitech.
Modern Logitech mice use either "MouseMan" or "Microsoft"
protocol."Microsoft" protocol."Mousesystems"
protocol. If it doesn't, it may work instead with the
"Microsoft" protocol although the third (middle) button won't
function.
3-button serial mice may also work with the "Mouseman"
protocol under which the third button may function as expected."Microsoft" protocol.
``PC'' or ``3'' will choose the "MouseSystems" protocol."IntelliMouse" protocol."IntelliMouse" protocol, you have to use it
as a regular 2- or 3-button serial mouse.If the "Auto" protocol is specified and the mouse seems working,
but you find that not all features of the mouse is available, that is
because the X server does not have native support for that model of mouse
and is using a ``compatible'' protocol according to PnP information.
If you suspect this is the case with your mouse, please enter a bugreport in bugzilla.freedesktop.org, using the xorg product.
If your mouse is connected to the USB port, it can either be supported
by the "Auto" protocol, or by an OS-specific protocol (see below),
or as a generic Human Interface Device by the "usb" protocol.
Mouse device drivers in your OS may use the standardized protocol
regardless of the model or the class of the mouse.
For example, SVR4 systems may support "Xqueue" protocol.
In FreeBSD the system mouse device /dev/sysmouse
uses the "SysMouse" protocol.
Please refer to the OS support section of this file for more information.
