I have the same problem on my nc10. After the update, the brightness did not work so I deleted your repository and have reinstalled but the problem was still there.
I tried installing "NC10-backlight" but always the same, it does not work
First, i'm french and i don't speak english very well.
I installed your repository. Everything works except Compiz. Indeed, when I mark "normal" in the visual effects, my pc slows down and my applets does not appear in my taskbar.
