Comment 39 for bug 350327

Thanks for confirming it is an issue still. Sorry it is not getting attention; there are literally thousands of X bug reports to Ubuntu and not very many people for working on them. Since there is limited resources, we tend to focus them on bug reports where the reporters have provided information needed to analyze the bug. I notice in this one there is one Xorg.0.log posted (which doesn't show any error message).

I would encourage those experiencing this bug to do a bit more digging to see if you can identify the error that is occuring. We have some docs to help give guidance on this at http://wiki.ubuntu.com/X/Troubleshooting/ although I'm not sure how much bearing they'll have on this specific problem. My gut tells me that perhaps nvidia simply doesn't support compositing screen operations over whatever protocol vinagre uses. If that's the case, there is really nothing we'll be able to do in ubuntu to resolve the problem, aside from just recommending compiz be turned off in such cases. Open to suggestions though...
