Public bug reported:
In 14.04 using kernel 3.13 the special function buttons of this HP
Compaq nx6310 laptop used to work correctly. I could increase or
decrease brightness, invoke the battery settings (mostly useless but it
worked), switch to an external display or enter sleep mode. The key

I ran a test with kernel 3.18-rc7-vivid where the problem persists. I
ran another test with 3.15.10-utopic where the functionality is as it

3.16 series.

obvious that after that change it won't work anymore. It would be
interesting to know w
Done, same as with 3.18.

Shouldn't it rather go to platform-driver-x86 given the hp-wmi driver
seems to be the culprit as the bisection has shown?
As the instructions advise I would CC the maintainer and the committer
(since it is a regression) as well.
