-It is possibile to customize the ACPI events to reassign the brightness keys to plain function keys, but it is not the preferred way (see [[#acpi_and_evemu|ACPI and evemu]]), because it requires to run an additional sofware layer (the acpid daemon) and the execution of slow action scripts.+It is possibile to customize the ACPI events to reassign the brightness keys to plain function keys, but it is not the preferred way (see [[#acpi_and_evemu|ACPI and evemu]]), because it requires to run an additional sofware layer (the acpid daemon) and the execution of slow action scripts. The simplest method is to **[[#customize_events_using_udev_and_hwdb|customize input events using udev and hwdb]]**.
  
 It seems that the LCD (DISPLAYTOGGLE) multimedia function is intercepted by the hardware and it is not handled as an input event nor as an ACPI event by the operating system. It seems that the LCD (DISPLAYTOGGLE) multimedia function is intercepted by the hardware and it is not handled as an input event nor as an ACPI event by the operating system.
