asgard2, thank you for testing Trusty. For now, I'm going to send this
to xorg for review, as this would appear to be an issue there, versus
the kernel.

Despite this, regarding the information you provided:
ubuntu@ubuntu:~$ xrandr --output HDMI-1-1 --auto
Floating point exception (core dumped)

If your OS is not in too bad of a shape, a window should pop open to allow you the opportunity to report a bug. If not, this should populate a crash file in the folder /var/crash , where it is recommended this is copied to your installed OS, and report from there via:
ubuntu-bug NAMEOFCRASHFILE

Just to clarify, in the best scenario from all the xrandr permutations
tested, while the external monitor was working via HDMI in Trusty, the
FPS was 1-3, and you would have graphics artifacts?

** Package changed: linux (Ubuntu) => xorg (Ubuntu)

Title:
  10de:0df4 [Dell XPS 15 L502X] no nouveau HDMI support with dual grafic
  card in Ubuntu 12.04LTS with 3.2.0-29-generic

Status in “xorg” package in Ubuntu:
  Incomplete

Bug description:
  The HDMI port is not working via Ubuntu 12.04LTS with 3.2.0-29-generic, newest nvidia driver with bumblebee.
  $ dpkg --status nvidia-current | grep Version
  Version: 304.37-0ubuntu1~precise~xup1

  This also doesn't work in Saucy via nouveau (i.e. no nvidia
  drivers+bumblebee).

  second monitor is plugged in on HDMI but is not recognized:
  $ xrandr
  Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192
  LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
     1366x768       60.1*+

  VGA1 disconnected (normal left inverted right x axis y axis)
  HDMI1 disconnected (normal left inverted right x axis y axis)

  WORKAROUND: connect the monitor on the mini DP connector over a DP adapter:
  $ xrandr
