f.lux and Redshift are the two major players for making your laptop screen turn red. I had f.lux working on Linux Mint but recently upgraded to Linux Mint 18 and it stopped working. I cannot get the applet to show so I cannot turn f.lux on or off.

My workaround was to install Redshift. It does not have a GUI, so it is even less customizable, but at least you get a red screen. It can easily be installed from the Software Manager and you need three packages to get it to work. The Goeclue2 is needed or Redshift will not start!

• Redshift
• Redshift-gtk
• Geoclue2

If you know how to get f.lux to start on Linux Mint, let me know!!
