Get flux for Linux
You may already have flux installed for Windows. Now you can also give your eyes a break and get flux for Linux as well. All you have to do is follow a few steps and you are done.
What is flux?
We have covered this before, but then here I go again. flux for Linux automates the screen display temperature so that your eyes are saved from the strain. Also it helps you sleep better at night. You can go through the studies confirming this here.
If you have a reasonably recent distribution you are good. In any case you can try by just firing your terminal by pressing Ctrl + Alt + T.
Now sequentially just run the commands as shown below.
sudo add-apt-repository ppa:kilian/f.lux sudo apt-get update sudo apt-get install fluxgui
The rest of the functionality is the same as the Windows version. You can select the coordinates so that flux for Linux can configure the color temperature itself. Or you can modify it yourself as well. Tick the Autostart icon on and flux will start as an applet. flux for Linux is based on Gnome’s AppIndicator. So Ubuntu 10.04+ versions are all fine. Just like all things open source, the code is available for you to look into and modify.

If you are using an older distribution there is hope for you too. You just need to download the archive from here.
It is possible that in some cases the pre-configured settings may not work with flux for Linux as intended but that may just be because of your monitors settings itself. In case nothing really works well for you, reset the monitor if possible and turn flux on. You should also try playing with the manual settings. The Preview feature also helps you to know what you are doing.
Get flux for Linux on and help your eyes and get a good sleep. Good Luck!
