Title:
10de:0dfa [HP EliteBook 8560w] Changing the screen brightness does not
work anymore in 319.xx

Bug description:
Changing the screen brightness always used to work on my HP Elitebook
8560w -- both with the function keys and in the dialog "Brightness &
Lock" in the system settings. The environment light sensor also used
to work IIRC.
Since the update to 13.10, this stopped working. Methods I have tried that
didn't work for adapting the brightness are:
* Adding GRUB_CMDLINE_LINUX="acpi_backlight=vendor" to /etc/default/grub
* Adding GRUB_CMDLINE_LINUX=”acpi_osi="!Windows 2012" to /etc/default/grub
Currently I am changing the brightness manually using xrandr --output
LVDS-0 --brightness 0.9. However, AFAIK this does not really change
the brightness, but only changes the contrast.
WORKAROUND: Use nvidia-graphics-drivers-304.
