Adjusts the color temperature of your screen
  20 reviews

The color temperature is set according to the position of the sun. A different color temperature is set during night and daytime. During twilight and early morning, the color temperature transitions smoothly from night to daytime temperature to allow your eyes to slowly adapt.

This package provides the base program.

I would give it 5 except for one irritation. When I use a VPN it locks in to the time zone of the VPN server. I would like it to stick to the time on the clock in the computer

I have a suggestion : add a setting to restore the day rules early in the morning because some people don't receive too much light everyday, so they need full light from their screen. Know that not enough light is bad for mental health. So filtering in the evening is good but only it the person is not in situation of privation., it is good to help to sleep too. So I know no reason to limit the light in the first hours of the day. I am a doctor in medecine to say this. So I think that changing the location of the current place toward the east is part of a solution, diffrent, for that purpose.

If you're looking for a graphical menu, download QRedshift from your Applets menu.

The program for the preservation of health. It is especially effective for inexpensive laptops with a cheap screen matrix.

Tried them all and the winner is Iris and Iris mini. Not even fair contest when it comes to usability and fast access to bluelight and dimmer.

It's awesome, if you want a smart yellow filter for your eyes look no further. Oh and be sure to use the applet for it.

Great program. Make sure to try the Redshift applet in the applets store if you wish to fine-tune the settings -- no need to create/change a config file. Just use the Applets command from your menu and check the download tab.

Functions perfectly, super-low on resources, able to set both day and night temperatures and brightness, by location, no snoops... What more could anyone want?

Excellent utility. It gradually shifts to a warmer screen around sunrise and sunset. Much better than f.lux (mostly used in Windows environments). I’m very happy with it.

After about a month of using this great little app, I can honestly say that my eyes don't hurt as much and are not dry after staring at screen late at night. My wholehearted recommendations!

Works perfectly. I just had to install geclue2-0 to work after installation.

only works if AFTER installation you run "sudo apt-get install geoclue-2.0"

If you don't start redshift, you need to find latitude and longitude coordinats. After this, "redshift -l :"

Works very well, once you are used to it you don't want to do without. Needs a manually added startup delay to start up reliably after rebooting.
