Does Wayland have an equivalent of xrandr for changing brightness and color temperature?

  • 772

xrandr can be used to change the display brightness using the command line. For example,

xrandr --output VGA-1 --brightness 0.4

Wayland does not support xrandr. Is there any similar tool in Wayland that can be used to control brightness and color temperature?

Note: This is NOT a duplicate of this question because that is about changing resolution, I want to control brightness on a desktop computer that does not support sys/class/backlight, so that frontends like Brightness Controller or Redshift can be made to work with Wayland.

  1. Yes, Wayland has an equivalent to xrandr. The package is called wlr-randr and is in the universe repository of Ubuntu 21.04 and later.

    You can find the project's webpage here: https://sr.ht/~emersion/wlr-randr/
