I rebooted and then booted with kernel 3.2.
So my system was 14.04 but with kernel 3.2.
Much to my surprise the brightness function keys did NOT work !!!
I booted a live USB with ubuntu 12.04 (kernel 3.2) and the brightness keys worked just fine.
So, is it NOT a kernel thing? Is it something else??? What could it be...????
Just another piece of information I would like to add.
As I said, I have ubuntu 14.04 installed with kernel 3.13.
I have downloaded from here: http:// kernel. ubuntu. com/~kernel- ppa/mainline/ v3.2.59- precise/ the latest 3.2 kernel and installed it.
More specifically I downloaded and installed the following 3 packages:
linux-headers- 3.2.59- 030259- generic_ 3.2.59- 030259. 201405181035_ amd64.deb 3.2.59- 030259_ 3.2.59- 030259. 201405181035_ all.deb 3.2.59- 030259- generic_ 3.2.59- 030259. 201405181035_ amd64.deb
