Not sure if this is the intended behavior but if one display is turned off via dpms (ie. a laptop screen)
grim errors out with (in this case
failed to copy output eDP-1
I would think grim would just grab the other existing display(s)
Right. I wonder if wlroots should just fill a black frame in this case. Or go through requesting a new frame for all visible clients on the DMPS'ed output, then capture.
I think this is fixed already... https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/3550
