A comment was added to Bug #34276 (a duplicate of this bug) by Bobby Feagin that should be added here as no one has mentioned it yet:
--- Another issue with the new gnome-screensaver. I always use the random screensaver mode, but now I can't pick which screensavers I want enabled. There are several installed screensavers that I don't like or cause problems, and I don't want them included in the random rotation. Since these are bundled together in packages, I can't uninstall the ones I don't like without hacking source code. Much less user friendly than giving us simple configuration options. --- This is not really a separate issue however; when "Random" is selected, clicking a Settings button should bring up a box to specifically allow you to choose which screensavers you want. -- no 'Settings' button in gnome-screensaver https://launchpad.net/bugs/22007 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
