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.
