Linux On My Samsung

Hello everyone, i have a N150 plus netbook.
until i used 10.04 ubuntu version it has been all right with touchpad behaviour.
after the upgrade to 10.10 (and 11.04) I have a really annoying touchpad scroll issue: it's almost useless because it's like too sensitive and the pages scrolls up and down as I simply put two fingers.

I googled much but i didn't find anything useful

Thanks in advance for any help.

Marco.

it would be great just to downgrade to older touchpad drivers

if someone has my problem, this fix it out (also in 11.04 with the latest kernel):

I didn't experience this issue with mine but thanks for the tip.
