I thought this site could be useful but maybe I was wrong, or maybe I can't use it well (it's more likely!). Somebody can post a guide of how use properly this site? (I'm italian)
But is more importantly my issue: when I had Ubuntu 8.04 on this Notebook Asus 1015 px, the combo FN + F7 worked since I formatted it the first time. From then FN + F7 don't work and I could not turn off anymore my LCD. It was a useful option for save energy on battery when I took notes at university! Now I have Ubuntu 12.10. It's possibile solve this problem? I no longer believe now, internet researches have been a waterhole!
Thanks a lot, Dimix!
