I tried the samsung-tools and istalled it. With no difference.
Then I installed samsung-brightness witch resultes no changes, too.
When I start samsung-tools all Buttons are activated, but why isn't there one for the arrow keys?
This ones works for me:
ESC go to sleep
F3 switches Webcam
F6 mute
Pos1 and End
My system:
Samsung N150 Eom
Ubuntu netbook remix Lucid Lynx 10.04
I hope you could give me an advice, to solve the problem.
Thanks a lot!
EDIT:
Get it by myself:
needed to update my system first

maybe old kernel or somthing...
please close the threat
