Comment 11 for bug 901211

I have had the same bug. I have a dual nvidia card (2 or 4 monitors) ge 440 and gt 550 ti. The problem is only when I try to use xinerama mode in unity 3d with dual card. gone 3 does not work. unity 2d and kde+kwin works. I laso have xrandr error about missing parameters (when I use unity 2d)
