Unity has nothing to do with that notification bubble and I don't know
the correct project to target.

Title:
  Laptop luminosity switch makes high CPU usage

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hello,

  The bug is as follows:

  If I try and switch the luminosity setting of my laptop my CPU goes to
  100% usage for 3-10 minutes, and the luminosity notification in unity
  (the one in the top right corner) flashes for the same amount of time.

  I am not sure if it is a linux bug or how to trace it. Please help.

  My laptop is an MSI EX705-X.
