    I can set the brightness on my Laptop with the CLI.
    For that I search in /proc/acpi/video...
    until I find a file called "brightness".

    Then I do
    Code:
    cat brightness
    and it prints the values it accepts.
    Code:
    10 20 30 40 ... 90 100
    Finally, I echo the brightness level I wish to that file.
    Code:
    echo "20" > brightness

    Hello and Welcome!

    Another suggestion would be to use keyboard shortcuts... manage to find your way to the preferences pane.

    Open a Terminal, hit 'Alt+e'... then 'o'
    This should open your profile preferences pane. You'll want to go to the 'Background' tab and set it accordingly.

    Remember guys I'm talking color brightness and I accidentally changed it from my catalyst control center.....
    I don't think if I change the system's color brightness to 0% my overalll color brightness =%50 cause %100 + %0/2 but I'm not about to risk anything...
    I managed to open it but didn't know how to reach the color part.....

    Maybe the aticonfig tool is of help. The Display attribute sections looks promising.

    Do not use ATI myself, but generally all settings in Linux are stored in some config file. User-level config files are stored in home directory. How about efiting that file? If this fails, removing ATI conf file will certainly reset it to defaults.
