Ditch The Blues At Night With the f.lux App For Linux
Research has shown that lack of sleep can lead to some type of cancer. Additionally, other researchers did state that continuous exposure to blue light during late hours — when blue light can sometimes be extremely difficult on eyes — can lead to sleep deprivation.
This means that those who frequently use their phones or computers at night tend to sleep few hours than normal due to their continuous exposure to blue light emitted from the displays and monitors of the phones and computers they use.
Apple did create a huge buzz when they released iOS 9.3 which comes with a feature called Night Shift.
Night Shift is a unique display-based feature that is set up based on the user’s location and it uses the changing of light through the day to adjust and cut down on the output of blue light from your phone. This makes the screen display a warmer yellow color as the day wears on which is so much easier on the eyes.
It should be noted that Apple — as they like to make every innovation theirs — is not the pioneer of this technology, in fact, the Play Store long since has Android apps which offer the same feature way before Apple came up with Night Shift.
Linux users can enjoy this feature through a software called f.lux which interestingly was available in the App Store and was unceremoniously taken down by Apple.
For those using Linux and other distros like Ubuntu, Elementary OS, Mint, or Linux Elite, smile because there is GUI based indicator applet that allows you to configure and use f.lux without much hassle.
Use this reliable PPA to install the f.lux applet by opening a terminal and using these command lines.
sudo add-apt-repository ppa:nathan-renniewaldock/flux
sudo apt-get update
sudo apt-get install fluxgui
For other Linux distributions that do not have the GUI based indicator applet, you can get the f.lux source code from the Github repository.
If you are on Ubuntu and have Unity as your desktop environment, using f.lux is really easy after its installed. Just head over to the Unity Dash and search for f.lux.
When the app is opened, it will ask you to enter the longitude and latitude of your current location. If you do not know it just click on the “Find My Longitude And Latitude Link” which should open a web window, check to see if location tracking is turn off and turn it on if it is.
When the pages on the web browsers have loaded, you get your longitude and latitude details on the browser, just copy it.
Now all you need to do is paste what you have copied to the appropriate space on the app.
You can twitch the lights to your preference and all the settings.
