  • One way to make things lighter (using software, not hardware) would be to use xgamma.

    Note that this will affect all applications in X.

    In a terminal, type

    xgamma -d :0.0 -gamma $gamma

    where $gamma is a number greater than one.

    to reset, simply type

    xgamma -d :0.0 -gamma 1

    which will set the gamma levels to the defaults.
