Message:

bugref:8087: Additions/x11: support non-root X server: call drm_kms_helper_hotplug_event() directly from the KMS driver rather than drm_helper_hpd_irq_event(). The second only accepts a hot-plug event as genuine if a screen is disconnected and then re-connected. Our screens are swapped without any intermediate disconnection.
