    There may be easier ways to do this, but off the top of my head the way I'd do it is to set up a cron job to modify the Screen Saver preference directly:

    Here's the command:
    $ defaults -currentHost write idleTime 0

    0 will cause the screen saver to never activate. To set the screen saver back to 30 minutes (1800 seconds), use:
    $ defaults -currentHost write idleTime 1800
