Comment 12 for bug 1283589

I have a Samsung NP530U3C-A01 laptop and I can confirm this bug affects my laptop. After applying the workaround script from juanmanuel in #3 and #4 I re-tested and the problem no longer appears.

Thanks juanmanuel for writing the fix and being so patient with Ubuntu's ridiculous bug policies - just don't lose your laptop otherwise we'll have to start this whole bug report process again!
