samsung q210 fn + up/down doesn't work

[gutek8654]

Binary package hint: hal-info

hi, I've got samsung q210 and have problem with brightness (fn + up/down)
I noticed, after upgrade hal-info to 20090227-0ubuntu1 fn+up/down exist but they doesn't work as I want. I can set brightness on 100% or 0%, no middle option, and after that I can't use keyboard. Menu (Applications, Places, etc.) doesn't work after use fn+up/down.
Something more about brightness: I can set brightness with brightness panel but only without NVidia drivers. If it is active brightness doesn't change (I test it on versions: 173, 177, 180.44 - everywhere is the same)

I don't know where write it, but I can't use fn+F9 (on/off wifi :/ ), nothing happens

I use Ubuntu 8.10
