Compiz mirrors screens on return from suspend/hibernate--dual monitors

[Chris Conatser]

Binary package hint: compiz

Expected behavior: upon return from suspend, dual monitors should show exactly what was on them before suspend.
Actual behavior: upon suspend, secondary monitor (located above primary monitor) shows what was on it before suspend, but primary monitor simply mirrors secondary monitor. Mouse pointer can move freely over both monitors as if they were a single large desktop (as though compiz does not realize that the background is simply a zombie mirror), but only secondary monitor responds to click.

Steps to reproduce:
1. Turn on computer (in my case, an HP dv100 notebook with an extra, external monitor--both monitors 1280x768; running Karmic clean install).
2. Log in.
3. Check that the two monitors are displaying separate images, creating a large dual-desktop.
4. Suspend/hibernate the computer (in my case, closing the lid works).
5. awaken the computer and type in password.
6. The secondary monitor (physically topmost) will look like before, but the primary monitor (laptop screen, located below the secondary monitor) will show a nonfunctional mirror of the secondary monitor.

Apologies for not attaching a log--Alt+F2 opens dialog box on my primary monitor, where it doesn't show or function when bug is in effect.
