--brightness brightness -
multiply the gamma values on the crtc currently attached to the output to specified floating value. Useful for overly bright or overly dim outputs. However, this is a software only modification, if your hardware has support to actually change the brightness, you will probably prefer to use xbacklight.
What does it mean?!

It means that it doesn't actually change the brightness of your monitor, it just applies a filter to the colors so they look brighter. It's the same thing TV commercial use to sound louder without changing your hardware volume control, only with light instead of sound. You shouldn't really mess with the gamma settings unless you're forced to use an old, burnt-out CRT ;-)

mosvy, thank you. I assumed that was the case. I will need to learn more about how it actually does it
