["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Matthew Haughton, thank you for reporting this and helping make Ubuntu
better. Could you please test the latest upstream kernel available from
the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-3.XY-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-3.XY-rcZ

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Title:
  regression: backlight can't be adjusted on UX32VD with
  3.19.0-12-generic kernel

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  The keyboard buttons are working as I get the on screen notification.
  But it has no effect on the backlight itself.

  I rebooted and switched back to 3.19.0-11-generic which works fine,
  rebooted and went back to 3.19.0-12-generic and it stopped working
  again, so very confident something broke in the new kernel version.
