Public bug reported: According to <https://wiki.ubuntu.com/Hotkeys/Troubleshooting>, "If the events are reported by more than one input device then report a kernel bug (Ubuntu linux package) because it should only send the event on one device." On my Latitude 2110, the brightness control keys (Fn+Up and Fn+Down) seem to appear through two different devices, /dev/input/event3 ("AT Translated Set 2 keyboard") and /dev/input/event4 ("Video Bus"). The keys also control the screen brightness, even in a text console.
