I'll take a look, but yes, it is a hard hang it becomes completely unresponsive including the network ports. I would imagine raring would have similar issues if it is an xorg intel problem. I've tried the newest available kernel with the newest updates with similar results. It's unique to my LG tv because it works well with a set of dell and Samsung monitors I've tested it with.

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.
