Reduce eye strain on Linux Ubuntu Systems. Install f.lux, a software that warms up your computer display at night, to match your indoor lighting. f.lux changes your computer display’s color temperature according to location and time of day.
F.lux changes your computer display’s color temperature according to location and time of day. f.lux fixes this: it makes the color of your computer’s display adapt to the time of day, warm at night and like sunlight during the day.
It’s even possible that you’re staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better. f.lux makes your computer screen look like the room you’re in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.
Tell f.lux what kind of lighting you have, and where you live. Then forget about it. f.lux will do the rest, automatically.
Settings are located in a menu to the left of your system clock. In Windows, this is at the bottom right corner of your screen. On a Mac, it’s at the upper right. NOTE: f.lux does not appear in your dock, settings, or your alt-tab menu. Currently settings are only acessible through the taskbar.
