Public bug reported: Since updating, about a couple weeks ago, whenever I plug my home Samsung SyncMaster P2450 external HDMI screen into my Dell XPS laptop, my desktop disappears and both screens go black. Even if I unplug the screen the laptop still stays dead. When I plug the cable in the firts time and I monitor my Xorg logs from another machine I get the following:

Restart lightdm does not work, unplugging the cable does nothing. Displays are dead. NOTE: This ONLY happens with this monitor. The older model samsung I have at the office works quite well, besides for a different bug I have logged here: https://bugs.launchpad.net/bugs/921540 A work around I have found is to delete my ~/.config/monitors.xml. So I have attached both the office working monitors file as well and my home one. But find that if I try adjust working settings afterwards at home I get the same issue described above and I have to end up deleting the monitors file again.
