Public bug reported:

I'm not sure whether this is a "false lockup" or not. The display became
unresponsive for maybe a second or two and then was back to life again
followed by the apport message.

Not sure what else I can provide information-wise other than this is a retina 
macbook pro early 2013 model with intel IGP 3rd Gen Core processor Graphics 
Controller (rev 09).
I have several usb devices hook-ed up:
- wireless is turned-on and associated with a network
- I have a display-port-to-vga adapter connected to one monitor and an 
hdmi-to-dvi adapter connected to another
- finally I also have a thunderbolt ethernet adapter plugged-in.

(my wireless adapter is the inbuilt broadcom 4331 running with
proprietary drivers.)

There should be plenty of attached debugging information from apport I
hope which might help better diagnose the problem than I can describe
it. It seems to be happening randomly and sporadically. I've had two
such notifications of GPU lockups today in the past 8 hours, which makes
it difficult to understand how one might reproduce the issue on-demand.
