[Jaunty] On laptop Acer TM6292 brightness hotkey events are sent by /video/input0 and isa0060/serio0/input0

Following instructions on https://wiki.ubuntu.com/Hotkeys/Troubleshooting :
On my laptop (Acer TM6292), if I press only one time Fn+LEFT ARROW (BRIGHTNESSDOWN hotkey), brightness levels decrease by 3 levels.
Same behavior with the Fn+RIGHT ARROW (BRIGHTNESSUP hotkey): It increase levels by 3 levels for only one key press.

I noticed that two devices sent events when I press these keys : /video/input0 and isa0060/serio0/input0
Here is the ouput of input-events for each device when I press these keys (first, one Fn+LEFT ARROW that one Fn+RIGHT ARROW):
$ sudo input-events 5

As you can see in input-events 5 (for isa0060/serio0/input0 device). Pressing FN+ARROW RIGHT also send KEY_KPPLUSMINUS. There is a bug report for that :

If need more information in order to diagnose that problem, do not hesitate to ask.

Same here, running latest Jaunty beta on my Acer Aspire 3620. All hotkeys except brightness work correctly.

[Fred (frederic-lespez)]

Same behavior under Karmic Alpha 3.
