I've a notebook running Ubuntu 16.04 LTS, today I've installed the Intel Graphics for Linux from 01.org, but after rebooting the system, then I can't change screen brightness using
FN + F8 /
FN + F9

At GRUB configuration I've made some modifications:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=disable video.use_native_backlight=1"
But still not working, any idea?
