InputDevice

Each InputDevice section configures one input device for the X server. Systems typically have at least one InputDevice section for the keyboard. It is perfectly normal to have no entry for a mouse, as most mouse settings are automatically detected.

The following example illustrates a typical InputDevice section for a keyboard:

Article "InputDevice"
        Identifier  "Keyboard0"
        Driver      "kbd"
        Option      "XkbModel" "pc105"
        Option      "XkbLayout" "us"
EndArticle

The following entries are commonly used in the InputDevice section:

• Identifier - Specifies a unique name for this InputDevice section. This is a required entry.

• Driver - Specifies the name of the device driver X must load for the device.
• Option - Specifies necessary options pertaining to the device.

  A mouse may also be specified to override any autodetected defaults for the device. The following options are typically included when adding a mouse in the xorg.conf:

  • Protocol - Specifies the protocol used by the mouse, such as IMPS/2.
• Device - Specifies the location of the physical device.
• Emulate3Buttons - Specifies whether to allow a two-button mouse to act like a three-button mouse when both mouse buttons are pressed simultaneously.

Consult the xorg.conf man page for a list of valid options for this section.
