I installed the Ubuntu 14.04 on Asus Q502LA laptop. Most of the things work fine, but brightness control does not work.
First, everytime on reboot, the brightness resets to 100% brightness.
Second, the keys (Fn+F5 and Fn+F6) do not work either.
I tried pretty much all of the suggestions that I could find here. None of them worked.
Did anyone have any success with getting the Fn+ keys working again to control the brightness in 14.04?
Thanks,
