I have to apologize, I do have a brightness shortcut in combination with the
'function' button.
I am astounded that Ubuntu does not have support for color, contrast and other
common monitor customization features. I am a photographer and need to be able
to have those controls. It surprises me that this seems to be overlooked or
maybe more accurately, is just not a priority?

Thanks to all that put there 2 cents worth in and to anyone that can solve this.
