Public bug reported:

Hi

 I have ubuntu 14.04 running on Dell E5430. Backlight control is working fine, but cannot be controlled via function keys (Fn+Up/Down). When xev started all other function keys works correctly, when Fn+UP/Down is pressed sometimes event is registered after +/- 10 seconds, sometimes is lost completely.
And the issue is gone after I suspend/resume the system :|
After reboot the issue is back again.

Let me know what info you need.

Cheers.
Piotr
