Automatically turn off the screen when idle for SDDM Wayland on KWin

I'm using Wayland for my SDDM as described in the wiki. So far, if I stays on the login screen without doing anything, the screen is kept on, which is annoying since it can be kept on for hours. In Plasma, the screen can automatically turns off normally. I wonder how to configure the screen to turn off if idled for 10 mins in SDDM?

I've tried copying `~/.config/powermanagementprofilesrc` and `~/.config/powerdevilrc` to `/var/lib/sddm/.config` and chown them to `sddm:sddm`, but it still not working.

Not directly  possible: https://bbs.archlinux.org/viewtopic.php?id=294006 -- if you need this keep SDDM on xorg is the simplest option. Or use another compositor for SDDM that can invoke DPMS on it's own.
