I have the same issue with an Acer Aspire 5734z-4512. Backlights controls show a notification, but do not do anything. I upgraded from Maverick, and the old kernel that I had still shows brightness just fine, but the latest ones do not...it goes black...fast. I tried all the fixes on here, and nothing works. I'm at bug# 773820. :)
