--- Comment #28 from Rodney Dawes <dobey.pwns at gmail.com> ---
Now running 3.13.0-1 on Ubuntu, and second display still not working, and no
link train errors in dmesg.

Second screen remains black. I can use both screens only when I set them to an
extremely low resolution of 1280x800 each. Any higher resolution, and the
second screen remains black.

If I run "xrandr --output HDMI3 --crtc 2" the second screen displays the
mirrored copy of the first screen, but I don't seem to be able to disable
mirroring with that. Disabling mirroring results in the second screen returning
to black.
