Filed a duplicate before finding this. See Bug #278086 in duplicates section.

I'm using Intrepid (beta packages) and Nvidia 8600GT with Nvidia-glx-177 restricted driver.

'Undirect Fullscreen Windows' fixed the screensaver problem, but is causing black screen after resume from standby, particularly when two user sessions are logged on when the machine is put into standby. Blindly typing password allowed logon, and alt-tab restored correct display of the desktop.

Disabling compiz allowed screensaver and display-blanking, as well as standby/hibernate/resume to function correctly.
