Alternative to f.lux for Ubuntu is Redshift

When using the computer in dimly lit surroundings, it helps to lower the brightness of the screen. One popular application for Windows was f.lux, and although they appear to have created a version for Linux, Ubuntu users don't need to install f.lux. We have Redshift.

Redshift can be installed hassle-free directly from the Ubuntu software center, but I was disappointed when I was not connected to the internet and Redshift didn't start because it wasn't able to access my location. I felt that's a dumb way to program a software.
Some laptops don't allow the brightness to go below a certain level, and the blue light from the screen is quite bright. Redshift creates and apparent reddish colour on the screen (although the blue light is still there) which is actually a bit comfortable.

Inspite of this, I'd still recommend having ambient lighting, and not working in the dark. Even with redshift, the monitor is bright and the surroundings are dark.

ps: Reports of digital screens making us lose sleep is a myth. We lose sleep because we force ourselves to stay awake. Not because of the digital screen's blue light. When you feel sleepy, just go to sleep instead of forcing yourself to stay awake longer.
