In the Ubiquity session, when selecting to try or install, leaving it for over half-an-hour did not activate the screensaver. Neither did leaving the installation process.
On the live-session, either going AFK, hitting Ctrl+L or selecting lock from the menu, nothing made the installer lock. I did manage to logout, however, and that left me with a red line like a TTY cursor that didn't accept text input, but I think this is a separate problem.
This appears to be fixed in the 20140529 build.
