[Bug 776738] [NEW] Expo plugin doesn't support "one wall per output" Multi Output Mode anymore


Public bug reported:

Binary package hint: compiz

The Multi Output Mode does not work as expected and either mode behaves
like the "One big wall" option. I find the "One wall per output" option
much more usable.

This is not specific to Nvidia Twinview, I also use an ATI Dual Display with Open Source drivers at work and this bug still occurs.
This is not specific to Unity (but might be closely related to it), the bug occurs with Unity and the classic desktop.
I can't say if this bug is specific to Ubuntu as I haven't installed Compiz on my other Linux distros (using Gnome3, KDE and OpenBox)
