Comment 6 for bug 496716

I'm now seeing this problem after having upgraded from 10.04 to 10.10. Previously, gnome-screensaver worked normally. After the upgrade, the screensaver will work correctly the first time or two after a reboot, but, afterwards, instead of the chosen screensaver only a black screen is shown. This is also true when the screensaver is activated via gnome-screensaver-command --activate. The screensaver preferences screen displays everything normally.
