I have gnome-screensaver setup to activate after 1 min of inactivity.  I have written a script that runs the following command in 30 second intervals:

 gnome-screensaver-command -p > /dev/null # for gnome-screensaver

This should keep gnome-screensaver from activating, but it does not; after the 1 min is up, the screensaver starts.

Normally, I use mplayer to view videos and it uses the very same command in ~/.mplayer/config to send the "heartbeat-cmd" every 30 seconds and gnome-screensaver ignore it as well.  That's why I tried it from a bash script.

Thoughts?

Running Arch Linux x86_64 with Gnome installed and system is up to date.

Glad to provides logs, etc. upon request.
