[mythtv-users] dpms stops working after a while

[Pat Pierce]

My system is set to shut down the monitor after 5 minutes,
which normally works just fine, but sometimes it stops working,
and the monitor will remain on, and I have to start turning off
the monitor manually when I leave it on the mythtv menu screens.
It will stay like that til I end up rebooting it or restarting gdm.
It seems to me it happens after mplayer or something exits
a video unexpectedly or something like that, but it's infrequent
enough that it is hard to pin down exactly what the deal is. I'm
using gnome 2.14.3 in ubuntu dapper drake.

Is there anyway to make gnome periodically check and/or
its dpms status without restarting gdm?
