Comment 16 for bug 129152

Eric. I fixed mine by turning off desktop effects, then the workspace switcher works correctly. I set the number of workspaces I wanted and any other settings (name workspaces, view on n rows etc.) then turned on desktop effects and everything worked fine. I had to go back to the open source ATI drivers to get desktop effects working. You shouldn't have to with Nvidia drivers. The problem I had with the desktop flashing through any open windows every few seconds was caused by a system monitor utility called Conky updating every 5 seconds. Turned that off and no problems. I also installed compiz-settings-manager to give me full control over desktop effects.
