Comment 12 for bug 385850

The only papercut-size fix I can see would be to remove the "Recommends" on xscreensaver-{data,gl} and rss-glx from gnome-screensaver and thus only install the native gnome-screensaver modes on new installations. This will leave the "cosmos" and "personal image folder" slideshows, which are pretty (cosmos at least) and resource-friendly.

Any solution involving selections of the existing screensavers (and leaving the possibility for those interested to enable others) would be non-trivial. Of course that should not stop anyone from coming up with a technical solution and a patch.
