When I try to load the psmouse module I get:

$ /sbin/rmmod psmouse
rmmod: ERROR: ../libkmod/libkmod-module.c:793 kmod_module_remove_module() could not remove 'psmouse': Operation not permitted
rmmod: ERROR: could not remove module psmouse: Operation not permitted
$ /sbin/modprobe psmouse

I tried /sbin/rmmod psmouse and /sbin/modprobe psmouse but the above result came out. AMD processor(64 bit) is installed in the laptop.


Use sudo to load and unload kernel modules:

$ sudo rmmod psmouse
$ sudo modprobe psmouse
