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.
