dim

Native Wayland screen dimming tool

Usage

[!NOTE] A Wayland compositor implementing the wlr-layer-shell-unstable-v1 protocol is required, e.g. Niri, Sway, Hyprland, River, Labwc.

After installing, you may run dim before you would run your locker, when you want the screen to dim for a period, e.g. in your swayidle config/command:

timeout 270 'dim && swaylock'

Would make it so that at 270 seconds, dim is run waiting for user input for the default of 30 seconds, then if no input is detected the next command will proceed, in this case swaylock will lock your screen.

dim should only finish successfully when no input is detected for the duration. If dim finishes successfully before this duration, please submit an issue.

The alpha and duration of dim may be configured with either a config file located at ~/.config/dim/config.toml, or through arguments at call-time, for all options and their defaults please see:

dim --help
