INPUTDEVICE SECTION in xorg.conf(5) man page contains: The config file may have multiple InputDevice sections. Recent X servers employ input hotplugging to add input devices, with the HAL backend being the default backend for X servers since 1.4. It is usually not necessary to provide InputDevice sections in the xorg.conf if hotplugging is enabled. By "it is usually not necessary", one may assume that one can still add them for additional options. However, if hotplugging is enabled, such options will be ignored. The description should add something like: If hotplugging is enabled and options need to be added, an InputClass section should be used instead of an InputDevice section. and perhaps replace "it is usually not necessary" by "it is usually incorrect".
