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_
* Adding GRUB_CMDLINE_
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.

As per Timo's hint, I reverted back to nvidia- graphics- drivers- 304 from the repos and am not experiencing this issue anymore. Of course, it would be desirable to have working 319 drivers, to get all the performance fixes crucial to OpenGL applications etc.
