As we can see in Example 4-5, it also loads some modules that are not used, identified with unused, including: parport_pc (the x450 does not provide a parallel port) isa_pnp (the x450 does not have any ISA buses) keybdev (the x450 does not support a standard keyboard device) joydev (for joystick support). You can unload any unused module with the rmmod command. Enter man rmmod for more information about rmmod options and parameters.
