[SOLVED] Fn brightness keys not working on a Sony Vaio + gnome 3.10

I'm aware a similar problem occured with some laptops and that it was fixed already with upstream patches, but in my SVE14113EBB laptop when I press the Fn + F5/F6 nothing happens. I can change the brightness with the Gnome menu slider but whenever I press the key combination to bring up/down the screen brightness nothing happens, not even the popup 'blob' appears like when I use the Fn + F3/F4 keys to raise/lower the volume.

By the way, I tried the suggestions here like passing 'acpi_backlight=vendor' as a kernel parameter but none worked

If all else fails, just map them with xbindkeys until they are either fixed upstream.

You won't get those popup 'blob' but it gets the trick done.  There are other ways like sxhkd https://bbs.archlinux.org/viewtopic.php?id=155613

But how am I going to report this upstream? Is it a gnome problem or an intel driver problem?

edit: upgrade to xf86-video-intel 2.99.907-1 solved the problem.
