xbacklight 1.2.3

Control display backlight

Xbacklight is used to adjust the backlight brightness where supported. It uses the RandR extension to find all outputs on the X server supporting backlight brightness control and changes them all in the same way.


Install xbacklight 1.2.3 as follows:

guix install xbacklight@1.2.3

Or install the latest version:

guix install xbacklight

You can also install packages in augmented, pure or containerized environments for development or simply to try them out without polluting your user profile. See the guix shell documentation for more information.
