I noticed there may be some bad interaction between gnome-screensaver and power managment. Indeed, my problem is that the screen turns off, rather than the screensaver starting. Disabling turn-off feature in power management seems to solve the issue. Maybe disabling the screensaver should disable turn-off feature too (and thus is a gnome bug)?
