I use the Acer Aspire 3 netbook. Lubuntu's brightness adjustment works
nicely, although it differs from Xubuntu. With Lubuntu, the screen has a
slightly eerie glow to it. Also, tilt the screen away from one, and it
goes dark. Tilt it towards one, and it goes bright. Xubuntu, on the
other hand, is
Indeed! It's more like a 'screen dimmer' than a true screen backlight
changer.

I have a similar netbook called Dell Inspiron 11 3162 in which this is
reproducible. Changing brightness with the FN (function) key
combinations change the gamma of the screen instead of the actual
brightness. It's a fake brightness change, like the one Redshift can do

I'd like to request some more info:
1. Could you record what this looks like?
2. The exact specs of your computer might help, too.
3. I'd urge you to use `xev` to figure out what keycode is being used.
4. Is there anything in the logs suggesting what is being done?

Gain meaning, the screen brightness is not affecting screen brightness but
affecting the wrong setting.
Gain means it will brighten some parts of the screen (make the mids brighter,
but keep the darks dark).
This causes overexposure, and the screen doesn't look nice anymore.
When I open the
Two questions:
1. What do you mean by "screen gain?" I know this as a static property
projection screens have, so I'm not sure how it's relevant.
2. If you open terminal and run `xev -event keyboard` and press the key in the
resulting window, what is the result?
