I have installed Ubuntu 12.04 (Precise Pangolin). If I open System Settings >> Displays there is a new (?) on/off button for a setting named Sticky edges.
Can someone tell me what this setting is supposed to control?

if you just wana change and save the screen brightness only, you can use xbacklight
sudo apt-get install xbacklight
after installing, type command to set the screen brightness easily
xbacklight -set `num`
the num is percentage of your screen brightness.
An easier way to set brightness and contrast
sudo setpci -s `00:02.0` F4.B=`XX`
to set brightness, 00:02.0 is your VGA device code.XX is hexadecimal form 00 to FF
use lspci command to find out your VGA device code.
xgamma -gamma `X`
to set contrast,X from 0 to 1
Hi yes this is in the System Setting -> Brightness and Lock
Then you can change the amount of time to turn the screen off.

It controls the mouse behaviour at the edges between monitors in a multi-monitor setup: If "Sticky Edges" is enabled the mouse stops on the edge.
See bug #965080 if you think this should be more obvious.
