Hey Chris,

(Not sure why the apport utility created multiple comments for all of
those attachments instead of grouping them like before....but oh well)

Anyways, I tried it again...this time I booted with my two DP monitors
plugged in. Started up fine, logged in...still good.

I switched the active workspace a few times left/right and then the
first monitor blanked.

I did it a few more times and then the second monitor blanked.

I then physically undocked the laptop, detaching both screens and
everything else, to send the captured system reports.

Maybe that will drop the amount of hotplug events you see to help filter
things out for debugging?

Are there any other debug options you'd like me to turn on/up? What else
can I do to help pinpoint the buffer underrun error?
