Combining xrandr, Redshift, and Darker Screen for a Redshifted, Darker Screen Experience
In this article, we will explore how to combine the xrandr command, Redshift, and a darker screen setting to achieve a redshifted and darker screen experience on your Linux machine. We will cover the key concepts, provide detailed context, and use subtitles and paragraphs to make the topic clear and accessible.
What is xrandr?
xrandr is a command-line tool for configuring the X Window System's output devices, such as monitors and projectors. It allows you to change the resolution, rotation, and reflection of your screen, as well as set the brightness level. The xrandr command is often used to troubleshoot display issues and to set up multi-monitor configurations.
What is Redshift?
Redshift is a software that adjusts the color temperature of your screen according to the time of day. This helps to reduce eye strain and improve sleep quality. By default, Redshift adjusts the color temperature of your screen to match the color temperature of the sun at your current location. However, you can also manually adjust the color temperature using command-line options.
Combining xrandr, Redshift, and a Darker Screen
By combining xrandr, Redshift, and a darker screen setting, you can achieve a redshifted and darker screen experience. This can be useful for reducing eye strain and improving sleep quality, especially when using your computer in a dimly lit environment.
Setting the Brightness Level with xrandr
To set the brightness level of your screen using xrandr, use the following command:
xrandr --output eDP --brightness 0.3This command sets the brightness level of the eDP output device to 30%. You can adjust the brightness level by changing the value of the --brightness option.
Using Redshift with a Custom Color Temperature
To use Redshift with a custom color temperature, use the following command:
redshift -O 3800This command sets the color temperature of your screen to 3800K. You can adjust the color temperature by changing the value of the -O option.
Combining xrandr, Redshift, and a Darker Screen
To combine xrandr, Redshift, and a darker screen setting, use the following command:
xrandr --output eDP --brightness 0.3; redshift -O 3800 -r -P -O 3800This command sets the brightness level of the eDP output device to 30%, and then adjusts the color temperature of your screen to 3800K using Redshift. The -r option tells Redshift to use the red component of the color temperature, and the -P option tells Redshift to use the purple component of the color temperature. The final -O 3800 option sets the color temperature to 3800K.
