no brightness control with Fn key and rt & lt arrow keys.
I have a new netbook: Acer Aspire One model 725. I installed Ubuntu 12.04.2LTS. The touch pad does not work (unless I push Ctrl + Fn + F7) and the Fn brightness does not work. I have tried several "fixes" but none have worked and one even "broke" my system and I had to reinstall Ubuntu.
I would like to get the Fn brightness control to work, as I often turn the brightness down to extend battery life.
