Not sure if it is fixed, or what fixed it, but it seems to be working
correctly now.. marking as fixed unless it happens again (and figure out
what exactly caused it).

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

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  [From last change: not sure if it was fixed, but the issue seems to
  have stopped within the last week of use, doing plenty of updates]

  
  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.
