Comment 31 for bug 543294

Sorry for not being clear before but here is some clarification:

keymap -i doens't produce any output for brightness up/down. In fact, none of fn+fX keys show anything when I "keymap -i input/event4". For example, I can use fn+f9 to enable/disable touchpad but "keymap -i" doesn't show anything. Same goes for volume up/down/mute - they work properly but keymap doens't print anything.

Thanks.
