Hi Ofir,
If you could also please test the latest upstream kernel available that
would be great. It will allow additional upstream developers to examine
the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds .

It's the same for me on a Lenovo Y450 with Intel Mobile 4 graphics, but I can
change the brightness with setpci -s 00:02.0 F4.B=FF where FF is a brightest
mode and 00:02.0 is from lspci | grep VGA.
I found this wokraround here: http://bbs.archlinux.org/viewtopic.php?id=73889
How could I set acpi
Lenovo Y450 with nvidia GeForce GT 130M graphics, not fixed for me

change it step-less, but thats ok for me)
Thank you for you good w
