Actually I have a /proc/acpi/sony folder with nothing in there
If I try to create a folder but I cant for some reason
:/proc/acpi/sony$ sudo mkdir brightness
[sudo] password for xxx:
mkdir: cannot create directory `brightness': No such file or directory
I am pretty new to linux so I might be doing something work here I dont now
Ask me for any output/information you need.
Its a friend computer so I might not have access to it right away know.
