Configuring Your Mouse Before using the xf86config 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.
Some mice come with adapters with which the connector can be converted to another.
The next thing to decide is a device node to use for the given interface. 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.
