This article mainly explains "how to automatically adjust the brightness of the screen on Linux". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to automatically adjust the screen brightness on Linux.

When you start to spend a lot of time in front of the computer, problems naturally begin to emerge. Is it healthy? How can I relieve the pressure on my eyes? Why does the light burn me? Although research to answer these questions is still ongoing, many programmers have adopted applications to change their daily habits and make their eyes healthier. Among these applications, I found two particularly interesting things: Calise and Redshift.

Calise

In intermittent development, Calise means "camera light sensor (Camera Light Sensor)". In other words, it is an open source program that calculates the backlight level of the screen based on the intensity of light received by the camera. Further, Calise can consider the weather in your area based on your geographic coordinates. I like it because it is compatible with all desktops, even non-X series.

It comes with both a command line interface and a graphical interface, supports multi-user configuration, and can even export data to CSV. After installation, you must quickly correct it before witnessing a miracle.

What is not very pleasant is that if you have delusions of voyeurism like me and put a piece of tape in front of your camera, it will be unfortunate, which will greatly affect the accuracy of Calise. In addition, Calise is also a great application that deserves our attention and support. As I mentioned earlier, it has gone through a difficult period of tinkering in the past few years, so I really hope this project will continue.

Redshift

If you've ever thought about reducing the pressure on your eyes caused by the screen, you've probably heard of f.lux, a free proprietary software that modifies the brightness and color matching of the monitor according to the time of day. However, if you really prefer open source software, then one option is: Redshift. Inspired by f. Luxury Redshift, you can also change the color and brightness to enhance your experience of sitting in front of the screen at night. At startup, you can use longitude and latitude to configure geographic coordinates, and then you can have it run in the tray. Redshift will smoothly adjust your color matching or screen according to the position of the sun. At night, you can see the warm color on the screen, which will make your eyes suffer less.

Like Calise, it provides a command line interface as well as a graphical client. To start Redshift quickly, simply use the command:

$redshift-l [LAT]: [LON]

Replace [LAT]: [LON] with your dimension and longitude.

However, it can also enter your coordinates through the gpsd module. For Arch Linux users, I recommend you read this wiki page.

The end.

All in all, Linux users have no reason not to protect their eyes. Calise and Redshift are both great. I really hope that their development can continue to give them the support they deserve. Of course, there are more programs than these two that can protect your eyes and stay healthy, but I think Calise and Redshift would be a good start.

At this point, I believe you have a deeper understanding of "how to automatically adjust the screen brightness on Linux". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
