So I reviewed the bug links in your most recent message suggesting that adjusting the aspi_osi parameter fixed your issue. I have not tried it, but did this fix it for you? I have been up and down the kernel ladder from v13.04 back to v10.10 and the issue persists for my system. Any input would be greatly appreciated =^)

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.
