It is definitely a bug. I think no one is working on that bug. I have looked at code, but I guess I wont be able to fix it. I have no time to study how compiz works and make necessary changes.
My pc setup is even more complicated. I have two nvidia cards with connected 4 monitors. I have two seats. One with 3 monitors/screens and second with two monitors/screens. One monitor is shared between both seats. So I have 5 screens - :0.1, :0.2, :0.3, :1.0, :1.1. I am using ubuntu 13.10 with pached nautilus, gedit, lightdm, xorg-server and unity-greeter. I have still 2 problems I would love to be resolved: 1) compiz not handling all screens. For this I am using workaround - I am starting compiz on each screen by adding new startup applications 2) https://bugs.launchpad.net/compiz/+bug/1158267 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/885989 Title: white screen on second monitor when using two xsessions Status in Nautilus: Confirmed Status in “nautilus” package in Ubuntu: Triaged Status in “nautilus” source package in Precise: Triaged Bug description: If enable dual head mode (two X screens), the second monitor went white after login with unity or unity-2d.
