LCD backlight controler is not working.

[WoAnerges]

Fn + brightness-\brightness+ = shows notification about brightness status (50%), but does not control the intensity of backlight. it's just stuck on 50% and that's all.

Ubuntu 10.04 x64,
notebook vaio vgn-nw21mf.

thank you for any help bro's.

I was having this problem, but fixed it.

Under the battery preferences I had it set so that brightness was lower when running on battery power. That setting appears to override the brightness applet. Once I changed the power management preferences the brightness went to where I wanted it.
