I thought you meant you didn't see any events at all until xrandr (which is a side-effect of not having udev). When we see a hotplug uevent, we iterate over all connectors looking for new outputs and comparing the connector->status on existing outputs, if the kernel reports that the output->status is different we send a RROutputChanged(output->randr_output, TRUE); and committed with RRTellChanged(screen). Hmm, what we seem to be missing is setting the RROutputSetConnection(). commit f5aabb7bddc6fc5dc910a983d1291c9864f65f06 Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Wed Sep 9 11:18:15 2015 +0100 sna: On hotplug events, update the output->status During the hotplug event, we query the current connector status and use that to trigger an output changed event to the clients. However, since we know the new status, we can set that on the RROutput immediately. Note the modelist is left unchanged, and will only be queried when the user requests it (though we may want to provide that in the hotplug notify as well).
