--- Comment #9 from spam at magnien.info ---
Upgrading from Ubuntu 12.10 to 13.04 caused this bug to appear on an Asus UX31A
computer with Intel HD4000 graphics.
Specifically, going into any full-screen game caused the external screen to
stop responding, with this error : [drm:intel_dp_complete_link_train] *ERROR*

Reverting to
linux-image-3.7.1-030701-generic_3.7.1-030701.201212171620_amd64.deb
solved the problem.
