Bug Description

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)

On a machine using an Nvidea Card, specificially, an older Mac Mini (using the experimental open source driver) this DOES work for me (I have expo across two monitors); on another, with a ATI Radeon card (using the proprietary driver), it doesn't.

I don't know if it's the graphic card / driver is what makes the difference, or something else.

I cannot reproduce this in current trunk anymore.
Also, soon it will be hopefully possible to select "One big wall" for non-same-resolution multimonitor configs again, see the screenshot here:

Although the original description tells nothing about the actual bug, I'm assuming as per comment #7 that this is a duplicate of bug 438580. Currently "One wall per output" doesn't render the workspace switcher correctly on the second monitor, which may look a lot like one large wall but is actually two walls overlapping each other.

Please check out if bug 438580 is the same as this. If I'm mistaken, please remove the duplicate status of this bug by clicking on the red "Remove linked duplicate bug" button at the top of this report and add a clear description with screenshots of the actual problem to this report.
