My Asus G75XV has the same problem, but xbacklight is working.
For some time the hotkeys were misplaced and working on left and right cursor arrows.
Try

$ xbacklight -10%

. Of course from within Xorg.

Re: ASUS X555L Screen Brightness doesn't work

They were[1] used at the beginning of X startup. But they were just the plain keys without any fn.

[1] Now has changed and they are disappeared. What does xbacklight to you ?
The rest of the reading is in the wiki. In particular some tweaking in the xorg.conf for nvidia card.
