Comment 54 for bug 1389215

Ok, so I upgraded my Lenovo w510 to Ubuntu 16.04 LTS Xenial Xerus and the problem persists. The fix I provide works, though when changing the brightness, it is jerky, i.e. it flashes between a low level and the actual selected level. But once the desired level reached, all is good.

So, can we finally introduce my fix into 14.04 and 16.04? At least, it provides a mean to change the brightness.
