Comment 16 for bug 1082139

I don't think it's a problem of nvidia proprietary driver, I tried to configure nouveau and notebook with intel video card the same way as I use nvidia driver but I wasn't able to. Because when you setting up driver with xrand it doesn't create two independent xorg screens, and the bug appears only when system has two xorg screens (":0.0" and ":0.1" in my case). And nvidia doesn't support xrand so people with these driver setting up two screens and there the bug appears.
