![]() Redshift is standard installed in Linux Mint 19. So correction of color temperature is only acceptable for non-color critical applications such as word processing and reading of documents. Note: You only change the color temperature if you are not working with color critical applications, such as photo editing as you will compensate for it and completely disturb your output. However, we can make some simple changes by adding some command options to the startup data. It is possible that you prefer to have a warmer color or maybe a bit colder color for the night time color temperature adjustment. The standard values in Redshift for day and night time are 6500 kelvin vs 3500 kelvin. Simply put, it is a matter of taste as we are all individuals who perceive light in different ways. It is a nice little app, but it is only a bit of a shame that Redshift does not give options in the standard GUI to adjust the color temperature to your liking.īut maybe your first question is, why would I even want another color temperature than the standard settings of Redshift. The Linux Mint repository contains the application Redshift to help control the emitting of blue light. When it is getting darker the color temperature of your screens should shift towards the orange spectrum (below 6500 kelvin) to compensate for that. To reduce these eyesight and sleeping problems, operating systems for laptops, desktops and mobile devices now have options to reduce the blue light and also schedule this for the most important moments of the day, namely when it is getting darker. Redshift controls the scheduling of the color temperature In this article I explain how to change default color temperature values of Redshift at startup. Linux Mint uses a simple but effective application called Redshift to prevent such effects, but the GUI does not allow you to set the values as you want. At the very least, it can lead to excessive fatigue due to disturbed sleeping patterns caused by adversely affected melatonin production (a hormone that regulates sleep and wakefulness), but researchers are also afraid of far-reaching effects, such as macular degeneration, which is damaging the light-sensitive cells in the retina. Under certain circumstances and with long-term exposure there are some concerns about possible long-term effects on the health of your eyes. Displays of computers and mobile devices emit significant amounts of blue light. Where 18.98:72.Lately we read and hear more and more about the dangers of looking too long at a screen that emits too much blue light in a dark environment. In gedit window add "-l 18.98:72.83" next to "Exec=redshift-gtk"Ĭomment=Color temperature adjustment tool ![]() Once you get your Latitude and Longitude from above, Go ahead and Edit autostart config file for Redshift, which is found in cd gedit sktop ** (process:3541): WARNING **: Could not get location, 3 retries left.Īccording to the geoclue provider we're at: 18.98, 72.83 Started Geoclue provider `Geoclue Master'. # In order to enable or disable this script just change the executionĬonnect your computer to internet and run gtk-redshift in Terminal. # Make sure that the script will "exit 0" on success or any other # This script is executed at the end of each multiuser runlevel. The file should look similar to this: #!/bin/sh -e You can find the path by typing whereis redshift. Add the path to redshift before the exit in the file or else it won't run. To add redshift you simply have to edit /etc/rc.local file. Upstart is more low-level than crontab and you need root privileges. ![]() So we can just add our program in there to have it run in every booutup. Upstart is a program that amongst other things, looks in specific folders at bootup for scripts to be run. Where 56.20:16.35 is the LATITUDE:LONGITUTE of your location. To see the list with the programs you can type crontab -lĪdd this line in the end, to boot redshift whenever computer starts up export DISPLAY=:0.0 & /usr/bin/redshift -l 56.20:16.35 Crontab is used a lot by system administrators for making backups and automating tasks. ![]() It has a list with programs and scripts and the exact dates or intervals that they should run. Crontab is a program that is running all the time. ![]()
