Help me, please. I can't work without flux. I tried everything. Flux does nothing (even when I press preview button), Night Color applet does nothing and Redshift gives "trying location provider 'geoclue2'" error

    You might want to try latest redshift from ppa:dobey/redshift-daily which has many fixes. Also, are you running Budgie 11 that's built on Qt/Wayland, or the older Budgie that's using Xorg? – dobey Dec 10 '18 at 14:14
  • Hasn't Budgie's move to qt stalled? Or do you have a link to a stable release version of Budgie 11? – DK Bose Dec 10 '18 at 14:41

If, for whatever reason, Flux, Redshift or the Night Color applet do not work for you, consider installing sct from the universe repository provided you're on 18.04 or higher. sct isn't available for 16.04 or older versions.

It's a small program and probably won't pull in many dependencies. You can try apt install -s sct to preview what will be installed: -s provides a simulation and doesn't need sudo.

If you do decide to try sct, man sct has

DESCRIPTION
       sct sets the screen's color temperature in a range from 1000 to 10000

OPTIONS
       temperature
              If passed a value in the correct range (see above) sct will set the current screen temperature to this value

       -h     If -h is passed sct will display usage information

       none   If no options are passed sct sets the color temperature to the default of 6500

So when you want a warmer screen, open a terminal and run sct 3500 for example. And when you want to revert to normalcy, just run sct.

    Using: apt policy sct returns: N: Unable to locate package sct. I've been digging through sct source code though and think I found the problem. Iniital release was July 2016 after Ubuntu 16.04 was published. I'm on 16.04 are you on 18.04? – WinEunuuchs2Unix Dec 09 '18 at 16:43

    Yes, I'm on 18.04. http://manpages.ubuntu.com/ confirms that sct isn't in 16.04. Sorry about that! I'll edit my answer. – DK Bose Dec 09 '18 at 16:47

Eyesome

I developed Eyesome that runs 24/7 to:

  • Control display brightness and gamma (night light, etc) for three monitors.
  • Each morning it gets the sunrise and sunset times from the internet based on your city name.
  • Brightness and gamma is gradually increased after sunrise
  • Brightness and gamma is gradually decreased before sunset
  • Sleeps ~ 12 hours daily and nightly unless resuming from suspend or monitors switched on/off

Sample Configuration - General Tab

enter image description here

Sample Configuration - Monitor 3 Tab
