Hello Linux Geeksters. As you may know, F.lux is an open-source software that adjusts the color temperature of your system, according to your timezone. It provides warm colors at night and sunny colors during the day.
All the users have to do is enter their latitude and longitude and set up the kind of lighting they have: Tungsten, Halogen, Fluorescent and Sunlight.
The latest version available is F.lux 1.1.8, which has been released a while ago.
In this article I will show you how to install F.lux 1.1.8 on Ubuntu 14.04 Trusty Tahr, Ubuntu 12.04 Precise Pangolin, Linux Mint 17 Qiana, Linux Mint 13 Maya, Pinguy OS 14.04, Elementary OS 0.3 Freya, Peppermint Five, Deepin 2014, LXLE 14.04, Linux Lite 2.0 and other Ubuntu 14.04 and Ubuntu 12.04 derivative systems.
Because it is available via PPA, installing F.lux 1.1.8 on Ubuntu 14.04 and Ubuntu 12.04 is easy. All you have to do is add the ppa to your system, update the local repository index and install the fluxgui package. Like this:
$ sudo add-apt-repository ppa: kilian / f.lux
$ sudo apt-get update
$ sudo apt-get install fluxgui
Optional, to remev fluxgui, do:
$ sudo apt-get remove fluxgui
