Comment 68 for bug 112518

I wish some effort were put into fixing this bug, but if that isn't the case, please at least read the whole post before answering and deciding that it isn't an issue. This could be a nvidia bug, it most definitely is not a compiz bug. Read the first post. Nothing about a white screen, it was a black screen that was frozen. Some posts down further explain that it occurs on Kubuntu with no compiz even installed. It has to be a bug that is related to xorg, which could be nvidia or not. Please don't disregard the post, but rather change what it applies to.
