Wlroots: HDMI unplugging not detected

HDMI unplugging not detected

• Configuration File:
  The default /etc/sway/config

• Description:
  Sway doesn't recognize the unplugging of the HDMI output.
  After unplugging the HDMI cable, the output will stay visible
  in the output of sway -t get_outputs.
  For reference, #2525 and #2536 are also by me with the same hardware.
  This time I checked, and it does work on X11, so it's a sway/wlroots thing.

Can you grab a drm_info dump after unplugging the HDMI connector?

[fwSmit]

This is very weird. The act of doing the drm dump makes it detect the disconnect. So I can only give you the drm_info with the information that it is disconnected.

drm_info force-probes the connectors via drmModeGetConnector.

This is a driver bug, nouveau should send a hotplug uevent. Please open an issue at https://gitlab.freedesktop.org/drm/nouveau
