Description kdebugs 2024-10-28 18:44:52 UTC

AFAIK there is no way on KDE/Wayland to query the state of DPMS for a monitor.

There is a method via ddccontrol or ddcutil (see here: https://unix.stackexchange.com/questions/785736/command-line-to-tell-if-monitor-is-off-in-wayland ) but it would be nice to have a more straightforward method, and kscreen-doctor seems like an appropriate tool for the job.

Having the info included in the results of -o would make sense, and we could have -d with no argument supplied print the current DPMS state.
