Back when I was using Ubuntu, I could install an app called Redshift, which is basically the Linux equivalent for f.lux.

Redshift is great. I have a systemd user unit for it, and I actually prefer it to Flux on OS X.

Setting up (configure/build + daemon) Redshift is bit pain, a built-in would be awesome, similar to the one just launched in GNOME.

Why did you build from source and make your own daemon instead of using the Ubuntu package?

There is f.lux for Ubuntu. Although maybe not for Unity? I use Gnome.

f.lux for Linux is an X11 app, it does not care for Unity or Gnome. You have to manually start it after you log-in, or find out how to make it autostart. Not very user-friendly.

Being X11 app means, it does not work with Wayland.

I'm running it with Unity

it has been broken for a while; nobody maintains it afaik

sudo apt-get install redshift redshift-gtk

This is a feature I'd really like as well, a blue light filter is a must for me on any device with a screen. I've always had problems with f.lux to behave correctly on Linux, so having one built into the OS (as an option of course) would be great.

I used redshift successfully for a time. It worked rather well but I don't know the current state (eg does it support wayland)

Redshift still works quite well. Maybe it should be pre-installed and better 'advertised'. Many people still don't know that this is a very nice feature to have.

Windows has recently integrated this in the 'creators update' as a feature. Would be nice to see Ubuntu follow suit.

macOS just got it too in 10.12.4

I would love to have that feature, automated blue light filtering and or screen dimming :)

+1 every system now has it. so make sense to join the club
