Sorry, when I saw it was a .deb file I had already sent de message.
I had no problem to install and it worked fine.
I have an Acer Aspire 5738

Fn keys work too, but I found a couple of isues:
* when using the Fn keys and you're near the less bright side it moves very
slowly (doesn't occur near the more bright side)
* It has a curious behaviour when connecting and disconnecting the power
adapter: sometimes changes brightness, sometimes not. Sometimes changes too
much, sometimes just to the half bright. And sometimes it changes even if
you don't do anything.

I hope it would help. I'm not an expert user, buy I offer my simple-user
experience.

Thanks to all of you
