Hello, I created the bug #60654
(https://bugzilla.kernel.org/show_bug.cgi?id=60654) in subject of backlight
control not works with my laptop. But the problem is complex and I receive an
advice to create another bug here to solve this problem.

I have a laptop HP Elitebook 8560w with a nVidia video card and the nouveau
driver. In fact the backlight control by keyboard was recognized (a GNOME's
pop-up appeared) but no effect on the backlight.

Use xbacklight or write in /sys/class/backlight/XXXX/ files did nothing.

Do you need more informpation about that ? 
Thank you in advance.
