Title:
  [Gateway NV77H] Brightness Keyboard Shortcuts no longer working after
  short time

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I am currently using Ubuntu 14.04 (upgraded from 13.10, and from that
  13.04) a Gateway NV77H Series laptop with an i5 core and intel's
  backlight controller. After the initial installation, the first bug
  workaround I had to do was set grub to have acpi_backlight=vendor, and
  that made brightness work in the first place. That should eventually
  be fixed, but the bigger problem I am having currently, is after the
  last upgrade to 14.04, the brightness keyboard shortcuts no longer
  work after a short period of time after boot. After reboot and log on,
  it all works fine, but after I focus to a window, it never seems to
  recover.
