Confirmed on ASUS X555LAB running Ubuntu 15.10.

$~# sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
X555LAB.503

First brightness was not working at all. Adding "acpi_osi=" at the end of GRUB_CMDLINE_LINUX_DEFAULT enables the brightness settings in system settings. Still Fn+F5 and Fn+F6 are not working. 
As a workaround I assigned Ctrl+F3 and  Ctrl+F4  to "xbacklight -dec 10" and "xbacklight -inc 10" to decrease and increase brightness. However this is suboptimal. 
Hope this "Brightness keys Fn+F5 and Fn+F6" problem can be fixed.
