backlight issue with laptop and 8.10

[Larissa Ardis]

Hi, folks...

I am a ubuntu newbie and mostly I love it. But - I can't control
backlight dimming. I want the backlight to be at max brightness at all
times and don't see how to do this. Currently, it appears to flicker
with ambient room light, dimming in dark rooms, getting brighter in
bright lighting conditions.

Details:

Seanix Z7100 laptop with Nvidia GeForce 6600 Go graphics. Is there
more info that would help disgnose or fix this?
