Comment 1 for bug 35170

Hello, many thanks for your bug report!

You've mentioned several key-combinations and I can't follow which ones do which. Could you write then out separately, eg:

  Brightness: Does nothing
  Volume: Shows indicator on screen; but no change in volume
  Hibernate: Doesn't work, doesn't show anything
  ...

You can see if the key-combations for these keys work by following the checks on:

Could you also post the dmidecode information for your laptop (see the bottom of that page).
