I have no idea to what package this belongs. Please file it under the
correct one.

Brightness doesn't change anymore in X.Org / GNOME Shell in 14.10. It
stays on maximum (10) and sometimes the less brightness down/less key
makes it go to 9 or 6. Each time I press the brightness down/less key,
the overlay with brightness setting shows up (so the key works.

I can set brightness to any level with
echo 1 >/sys/class/backlight/acpi_video0/brightness
echo 2 >/sys/class/backlight/acpi_video0/brightness
...
echo 10 >/sys/class/backlight/acpi_video0/brightness
and the display responds properly and I can read out the value with
cat /sys/class/backlight/acpi_video0/brightness
but changing it with keys only goes from 10 to 9 or 10 to 6.

This used to work in older versions of Ubuntu. Please fix this and let
me know how  I can fix this temporarily.
