ray@ray-desktop:~$ lsinput
The program 'lsinput' is currently not installed. You can install it by typing:
sudo apt-get install input-utils
ray@ray-desktop:~$ sudo apt-get install input-utils
[sudo] password for ray:

it installed then:
ray@ray-desktop:~$ lsinput
open /dev/input/event0: Permission denied
ray@ray-desktop:~$ sudo lsinput
