Comment 83 for bug 1308105

@Steve
I guess that Olivier, Alexander or Sean are more suitable to tackle this than me, all I did was to give some instructions and update the patch, so don't expect a patch from me any sooner.
I use a 27" display and 19" in extended mode(configured via NVidia Settings) and everything works smoothly, but as soon as possible, I'll give it a go(with and without patches) and see what happens while switching, plugging and unplugging them.
