First things first, this question is already asked, but is 2 years old and without an answer. Now my problem...
I have one monitor with another from my laptop. That's my workspace. But when I install f.lux the app only worked on the laptop's monitor and not on the external. Why? I tried Redshift but I can't lower down the redness on the screens and unfortunately, it works on dual monitors.
So can someone share some workaround?
Thank you.
p.s. I have Ubuntu 14.04 32bit
