Hi Christopher, thank you for looking into this. I'm running Ubuntu MATE
15.04 at the moment, and the problem doesn't happen in that distro.

Maybe somebody else will be able to pick up this bug from where I left
off?

Title:
  Soft buttons and keyboard shortcuts sometimes don't work on HP
  EliteBook 6930p

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  On my HP EliteBook 6930p, there are some soft buttons, the most
  important being Mute, Volume Up, Volume Down.

  Sometimes, these soft buttons don't work. Interesting: in those cases,
  normal keyboard shortcuts (for example: Ctrl + Alt + T for opening a
  terminal) also don't work. I  have to reboot my system, and then, they
  usually work again.

  In those cases, the buttons themselves do work: the mute button
  indicator on the keyboard will switch from blue to red and the volume
  buttons will do a 'bouncing' animation to confirm that you've pressed
  those buttons. Additionally, I do believe that in those cases the
  buttons are interpreted somehow by the system, because for instance,
  when running

  xev | grep -A2 --line-buffered '^KeyRelease' | sed -n '/keycode
  /s/^.*keycode \([0-9]*\).* (.*, \(.*\)).*$/\1 \2/p'

  (source:
  https://wiki.archlinux.org/index.php/Extra_keyboard_keys#In_Xorg)

  I get the following output when pressing those buttons:

  
  36 Return
  122 XF86AudioLowerVolume
  123 XF86AudioRaiseVolume


  So there must be something else going on. I just don't know what to do
  from here. Any help here is appreciated.
