I do not have this directory.

kernel 3.14.2 is running and nouveau mod is loaded, in result the unneeded
discrete nvidia card is running without bbswitch mod.
Maybe there is a needed package not installed?
Note, in my notebook (MSI fx700) bios i don't have an option to switch/power
off graphic cards.
