Sorry, you're far too late, for me at least. That machine broke down a
couple of years ago.

Title:
  [Samsung NP-NC10-KA01AE] Brightness control no longer works properly

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  The Fn+Brightness keys on the Samsung NC-10, which need a quirk to
  work, did not work with any Oneiric kernel until 3.0.0-15. This
  appears to be because (according to the Changelog) a quirk was added
  to that version. Previously, I had been using the latest natty kernel,
  which continued to work.

  Unfortunately, though I can see nothing relevant in the Changelog,
  3.0.0-16 breaks this functionality again: the brightness controls
  allow only the minimum, minimum + 1, and maximum brightness levels to
  be set, but nothing intermediate.
