Perhaps this PPA could help you.

@herf Is there something new? I really miss this feature too.

@mquiles start "xflux" from the command line, and do xflux -h or similar and you'll find the commands.

You can use

xflux -l 12300 -t 6000:2700

to rune flux with different daytime color, and your preferred nighttime color.

I don't know why is not maintained anymore by Kilian but the original GIT repository provides the link to the project discussed above.
Old GIT:
https://github.com/Kilian/f.lux-indicator-applet which links the new maintained one at:
https://github.com/xflux-gui/xflux-gui

If you have any concerns you could always remove the source and don't update the application.
No, I am not associated with the project.
Hope it helps.

@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
Disable

For some Nvidia users downgrading the driver to version 361.42 solved the problem.

Xflux needs to be adjusted to the 11th bit.

@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.

O.K. whoops, forgot about ARM! Disregard above!

That's right, the simplest way to install f.lux on Debian (7 / 8 / LMDE2) is by downloading the binary and installing it to your /usr/local/bin/ directory.

On top of this, you could also install Xflux, which is a nice GUI for f.lux available here on GitHub...

If anyone is interested, I have a wiki page of mine that explains this in details ;-)

Found another option to f.lux, apart from redshift. It is called Iris and you can install it or you can download the micro version which is the one I am using. It is a portable very little executable with a couple of scripts (day mode and night mode), and you can also create your own very easily.

Yes. Updating the linux version would be great and adding other options like being able to turn it on during day time :)

I also have the same question several months ago. I recommend you use the redshift instead. There is a easy method to pre-set the location of redshift, so it will automatically start even without the internet connection.

The second answer of the following link gives you the solution.

xflux daemon (command line, but for X-Windows)
September 2013

A 64-bit version with multiple monitor support is available here: xflux64.tgz

A 32-bit build with support for multiple monitors is available here: xflux-pre.tgz

Download one of those two files. Then, you will want to extract that, like a zip folder. So right click the downloaded folder and click "Extract here" or if you're on KDE choose "Extract to folder "xflux-pre"".

Then, drag the xflux file inside the new folder, into a terminal. Or do cd ./home/downloads/xflux-pre/ or something like that to get into the folder.

Then do xflux -h

xflux -l -80:50 -k 2300 is a place to start.
