@BLOKKSTA90 Install Wine (Wine is not an emulator) that can load some windows programs. I'm not sure what the latest version is but here's the main website: https://www.winehq.org/
Install that by following the instructions here: https://wiki.winehq.org/Ubuntu I'm not sure if they'll translate or work as is, but if you run into trouble, here would not be the place to ask for help with installing Wine.
Once wine is installed, install f.lux just like you would on a windows computer and download the .exe file.
@lorna Since Android Apps are on their way, would f.Lux work on ChromeOS on the system level rather than an extension? I noticed this flag enabled, I'm not a programmer but would love to see F.lux on ChromeOS.
Color calibration of the display Chrome OS
Allow color calibration of the display if the display supports the feature. #disable-display-color-calibration
@Cruppellarius Yes, but I cannot recommend f.lux, unless you'd like to run it through Wine. A good alternative that got updated and finally accurate color tables since 1.9 is redshift, and it does an excellent job of matching f.lux on settings that I have tried such as 5500K and 2700. I hope the f.lux has time to work on the linux build when they get done with windows and mac variants.
