Public bug reported:

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. The
included log from 'ubuntu-bug linux' might give a few extra bug reports
as well, but this is probably more important since it has to deal with a
common function of a laptop.

I am also sorry about not knowing what the package is, but the nature of
this bug, probably won't throw an exception anywhere, so locating it may
be difficult for my level of understanding.
