How can I disable the Screen Saver on the login window?

You can edit the .plist file at /Library/Preferences/com.apple.screensaver either using a text editor, Plist Editor (requires the OS X Developer Tools) or the defaults command in Terminal to remove the screensaver at login window.

Like this:

sudo defaults write /Library/Preferences/com.apple.screensaver loginWindowIdleTime 0

I believe this does the trick (at least it seems to have worked for mefor several hours now):

sudo defaults write /Library/Preferences/com.apple.screensaver loginWindowIdleTime 0

This disables the screensaver in the loginwindow.
