--- Comment #12 from Emil G <emil__gustafsson at hotmail.com> ---
I'm running Arch Linux on a docked Dell E7440. With this patch applied to
Arch's 3.13.5 kernel, the 'failed to train DP' error disappears but xrandr
still reports the output as DP1 independent of physical port. Further, xrandr
fails to separate dual monitors and reports them as a combined screen on DP1.
