If you need to manually start the applet just type 'fluxgui' in terminal.

Resource: Flux Repo

sudo add-apt-repository ppa:nathan-renniewaldock/flux
sudo apt-get update
sudo apt-get install fluxgui
Enter fullscreen mode Exit fullscreen mode

Resource: Create a Cron Task in Ubuntu

Check if cron is installed:

dpkg -l cron
Enter fullscreen mode Exit fullscreen mode

Install cron (if needed)

sudo apt-get install cron
Enter fullscreen mode Exit fullscreen mode

Verify cron is running.

systemctl status cron
Enter fullscreen mode Exit fullscreen mode

Create a new cron job.

crontab -e
Enter fullscreen mode Exit fullscreen mode

Select your terminal editor of choice.

Resource: Crontab Generator

Use the Crontab Generator to select when you want fluxgui to run.
FYI: 'Command To Execute' field on Crontab Generator is 'fluxgui'

Verify cron job was created.

crontab -l
Enter fullscreen mode Exit fullscreen mode

If you need to manually start the applet just type 'fluxgui' in terminal.

Winning! You're good to go.

Just downloaded it on my Mac. I was already using the default Night Shift but I think this will ease my eye strain a lot more. I will start using it when I have a good sleeping schedule, right now I'm nocturnal 😬

When I’ve used it at night I noticed I was getting tired earlier; try it out tonight. Well, it may not work - make you sleeper - if you have led bulbs in your room or look at your phone. But it still helps with the eye strain 😊

I used to on macOS and I think is amazing software. I was using the default night on Ubuntu but f.lux is more better than default night mode.
