Thanks for testing those. Since using what was basically the latest
upstream kernel didn't help, it sounds like this is something that needs
to be addressed upstream. That doesn't mean that we'll stop trying to
find a temp solution, just that a fix may originate quicker from
upstream. If you would, please open an upstream bug report at
https://bugzilla.kernel.org. This will point out your issue to the
developers, and may provide a resolution more quickly.

If you feel comfortable opening a bug upstream, it would be helpful if
you would post the upstream bug number as a comment here, so that we can
link this to the appropriate upstream report. While you are doing that,
I'm going to finish looking over the provided logs and should have a few
other things that we can try out a bit later today.

Title:
  Clevo W350ST brightness keys don't work on Kubuntu

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  The Fn+F8 and Fn+F9 keys are not working on my Clevo W350ST with
  Kubuntu Raring to change screen brightness of the internal laptop
  screen. I installed linux-headers-3.11.0-4, linux-
  headers-3.11.0-4-generic,  linux-image-3.11.0-4-generic and linux-
  image-extra-3.11.0-4-generic  from Saucy packages repository but the
  problem persists.

  When trying:

  $ xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'                                                            
  keycode 36 = (keysym 0xff0d, Return), state = 0x10                                           
  keycode 232 = (keysym 0x1008ff03, XF86MonBrightnessDown), state = 0x10                       
  keycode 233 = (keysym 0x1008ff02, XF86MonBrightnessUp), state = 0x10

  Event codes appear correctly.

  And changing:

  /sys/class/backlight/intel_backlight/brightness

  changes the brightness of the screen, but pressing the key combination
  does not. I believe this happens because the key combination is, in
  fact, changing the value of

  /sys/class/backlight/acpi_video0/brightness

  I have

  http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu
  http://ppa.launchpad.net/bumblebee/stable/ubuntu

  in my package sources

  Thanks!
