Brightness control works fine on my Dell laptop. Could this be a
    hardware problem  on my new Acer Aspire (it worked fine on my
    previous Acer laptop ...)?

Title:
  Brightness control not working on Acer Aspire E1-531

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have been advised to post this problem as a bug. Having used Ubuntu
  12.04 for several years, I recently purchased a new laptop, an Acer
  Aspire E1-531, and the screen brightness control doesn't work - with
  12.04 or 13.10. When the slider is moved back and forth there is no
  change  - the screen remains on full brightness.  Several helpful
  suggestions to fix this have been provided via Launchpad, but none
  were successful - hence listing the problem as a bug. My daughter has
  my previous Dell laptop running 12.04 and the brightness works
  perfectly. Ditto my Asus netbook.  But NOT on my Aspire. Having
  Googled the problem in search of a solution, I find many people with
  the same problem with other machines.
