Subject: [PATCH] drm/qxl: only report first monitor as connected if we have no state
Date: Thu, 17 Sep 2015 06:27:18 +1000 [thread overview]
Message-ID: <1442435238-12959-1-git-send-email-airlied@gmail.com> (raw)
From: Dave Airlie <airlied@redhat.com>
If the server isn't new enough to give us state, report the first
monitor as always connected, otherwise believe the server side.
