Brightness problem with 12.10 (32-Bits version)

[demonmusic]

I have problems using the brightness control on my Acer Aspire TimelineX 1830T (w/ Kubuntu 12.10) -

It seems to work for the system (the brightness bar goes up and down If I try to change the brightness with battery brightness indactor) but nothing happens.

And If I try it with control keys, brightness try to change, but do it slowly freezing my system.

Can you help me, please? Thanx!
