    • Worked immediately in Ubuntu 14.04. Not able to adjust settings yet and I wonder about RedshiftGUI but this'll do for now. Guest • Sep 2017 • 2 agrees and 3 disagrees Disagree   Agree

    • Has minimal performance impact and can be configured to have no impact at all (at the cost of smoothness). Best choice if you are a gamer. Guest • Mar 2017 • 4 agrees and 1 disagrees Disagree   Agree
    • + Free & open source + Adds the feature of setting your own sunset and sunrise times, which the f.lux developer(s) did not want to add + Access to the keyboard/mouse logging hook MSCTF.dll can be declined without affecting functionality except for the ability to configure quick-keys - Occasionally crashes when denied a permission by comodo HIPS, but nothing so regular that it gets in the way of use.
