Modules used by the default kernel
Linux provides a default kernel that loads almost all the drivers we will need for
our x455, and also some drivers we will never use.
As we can see in Example 4-4, it also loads some modules that are not used,
identified with
unused
. You can unload any unused module with the
rmmod
command. Enter
man rmmod
for more information about rmmod options and
parameters.
