On my laptop, as it turns out, the AMD dGPU can get in some sort of power saving state where it doesn't detect hotplugged monitors until a TTY switch or, apparently, even simply running lspci. I should check if force-probbing connectors with DrmScanner helps this (same thing as in device_changed()). If so, maybe it would be worth to force-probe when trying to run niri msg outputs and such.
