I upgraded to raring and am currently using the 3.8.0-6.13 kernel. The
problem has gotten worse. The machine will not boot while connected to
the external monitor. It still continues to hard freeze when the monitor
is connected while the machine is running.

Title:
  [gm45] Hard hang when plugging, unplugging, or turning off LG 55LE5400
  TV

Status in “xserver-xorg-video-intel” package in Ubuntu:
  Incomplete

Bug description:
  The system crashes whenever breaking the connection between the
  television and computer outputs. It's not a broad problem because the
  EDID for dell computer monitors is correct and they work just fine;
  however, my 24" samsung computer monitor and and LG HDMI TV cause the
  same problem. I've tried using a few bash scripts that modify the
  monitor settings using xrandr, but it must be an infinite loop issue
  in xorg that isn't properly handling the monitor switch.

  I'm using a SONY VAIO FW250J (this is a similar bug to a few others
  already listed). The graphics driver should be supported by the open
  source intel graphics drivers (chipset GM45, GMA 4500 MHD). I
  originally thought it was a graphics driver issue, but transitioned to
  thining it was a hardware compatibility issue after tooling forward
  and backwards with the xserver-xorg-video-intel graphcs. I can't rule
  out a compatibilty issue mostly because it's a SONY laptop (they like
  to do things differently). I'll probably dive into xorg intel graphics
  source code to poke around, but doubt I'll uncover the issue.
