I like turning off the monitor when I don't need it, to reduce eyestrain and energy consumption (e. g. when only listening to music). On X11, I have been using the sleep 0.5; xset dpms force off shell command and assigned it a custom keyboard shortcut.

Recently, I've switched my entire workflow to Wayland, and the xset dpms commands apparently don't work on this platform - output says server does not have an extension for dpms option.

Is there an alternative method which I can use to turn off the monitor on Wayland? If not, where do I need to open a feature request?
