    • 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

    • + 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. Guest • May 2017 • 3 agrees and 0 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

    • So happy I can set my own times. In the winter the sunsets happened way to earlier in Flux, then I'd turn it off and forget to turn it back on. Guest • Jan 2017 • 2 agrees and 0 disagrees Disagree   Agree

    • Redshift is Nerdware - Hard to set up Guest • Mar 2017 Disagree   Agree
    • A Hole Pletora of Configuration Options in comparison with F.lux, allowing setting for Daylight color, Transition Time of any user specified Duration, Full Disable of Program ( not just for a temporary specified time period ), HSB Color Schemes in addition to just Kelvin temperature profiles.
