[Harry P <1519282@xxxxxxxxxxxxxxxxxx>]

Sorry Christopher, I'm not sure this should be closed.  An Ubuntu
install with UEFI boot consistently shows the problem.  An install with
old-style BIOS does not.  So the problem is with Ubuntu's UEFI boot
loader, which I'm sure the team would want to fix, since it's meant to
be the preferred way of booting PCs these days?

This might mean you want to reassign the bug to a different package,
rather than closing it?

Title:
  Keyboard backlight stopped working after upgrade to Wily

Status in efibootmgr package in Ubuntu:
  New

Bug description:
  I'm using a Samsung Ativ Book 9.  Keyboard backlight worked OK under
  Vivid, seems to have stopped working since I installed Wily.  Can't
  see any evidence of it in /sys/class.

  Happy to do any further debugging if it helps.
