How to Install and Use Redshift in Ubuntu

Redshift is a more effective and amazing tool in case you are using a laptop/PC for a longer period of time. You can also take advantage of redshift for regular use cases. As redshift has an outstanding feature of maintaining the color temperature of your laptop/PC screen as per your wish. It can adjust color temperature for daylight or the night time too. With this feature, it makes the users more comfortable to use their laptop/pc.

In this article, we are going to install and show the cool feature by using it on Ubuntu 20.04 LTS.

How to install Redshift in Ubuntu 20.04 LTS

How to configure and Use Redshift in Ubuntu 20.04 LTS

You can search for the default configuration file at ~/.config/redshift.conf, if not available you can create a file and write the configurations as per your need for the color temperature. The daytime temperature is 6500K by default and 4500K for night. You can adjust as per your need.

You can create your configuration file with an editor like vim as shown below.

$ vim ~/.config/redshift.conf

Save the configuration now. Here, you can see configurations for temp-day, temp night, dawn-time, dusk-time, brightness-day, brightness-night, gamma, latitude, longitude, and screen. You can also change or adjust these configurations by running the syntax as shown below.

Adjusting Gamma for day and night

gamma = 0.8

Adjusting Gamma for day only

gamma-day = 0.8:0.7:0.8

Adjusting Gamma for night only

gamma-night = 0.6

temp-day = 5600

Adjusting the color temperature for night only

temp-night = 3500

How to Use Redshift with GUI in Ubuntu

You have learned to use redshift with the command line and set the configurations as per your need. But normally, you can also use redshift with GUI interface. You can simply search it on the application manager and it will be launched after you select redshift.
