Is this Kubuntu or Ubuntu? Which version?
Can you provide data as requested in https://wiki.ubuntu.com/KubuntuLaptopKeycodes ?

this is Kubuntu 7.10 desktop amd64, as stated in the bug title/body.

in a terminal, i ran xev | grep -A2 --line-buffered '^KeyRelease' |
sed -n '/keycode /s/^.*keycode \([0-9]*\).* (.*, \(.*\)).*$/\1 \2/p'
and then i pressed Fn,UpArrow,DownArrow and then i released Fn key,
and pressed A, and then i pressed Fn,F3. this is the output

212 NoSymbol
212 NoSymbol
101 NoSymbol
101 NoSymbol
38 a
241 XF86LaunchB

i think Fn+F3 works (which has a battery sign on it, and when pressed
shows the battery/cpu usage u would see when u move ur pointer over
Power Manager in system tray) but Fn+Up and Fn+Down does not work
(they are supposed to increase decrease screen brightness according to
the signs on them).

Is there any development on this bug's fix? I see the state has been set to incomplete. what does that mean?

[JoshuaKersey (goodtimetribe)]

I'm experiencing the same problem too.
