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.
