Comment 2 for bug 574386

I have 3 nvidia 9400 GTs with 6 monitors. After upgrading to 10.04 my mouse is flickering uncontrollably if I try to move it into one of my upper monitors. (my upper row monitors are running off the screen 1 port of each device)

Interestingly I find if I disable Xinerama in the xorg.conf then the mouse behaves (but of course you can't drag windows between monitors)

It just looks to me like the mouse issue may be somehow related to xinerama
