Simon Ser 1c4a625fe3 backend/drm: ensure disconnected outputs are disabled after VT switch ... The following situation can be dangerous: - Output DP-1 is plugged in, compositor enables it. - User VT switches away. - User unplugs DP-1. - User VT switches back. - scan_drm_connectors() figures out the output is now disconnected, uninitializes the struct wlr_output. - The loop restoring previous output state in handle_session_active() accesses the struct wlr_output to figure out what to restore. By chance, we zero out the struct wlr_output after uninitializing it, so enabled and current_mode will always be zero. But let's make sure we handle this case explicitly, to remind future readers that it exists and make the code less fragile.		2022-11-11 22:44:53 +00:00
