Comment 3 for bug 178341

I'm running the same configuration with a Nvidia 8400M GS and can confirm the behaviors listed in points one, two , and three. I also tried setting gtk-menu-popup-delay=0 but the first head still has this delay. The second head also has no window borders and the Quit button behaves as described.

Setting the number of workspaces through the advanced Compiz configuration dialog worked for me. The Workspace switcher didn't show me the option.
