xscreensaver blanking display too soon

[Paulo Silva]

I don't know if this is related to xscreensaver or power-management -
i tried to set xscreensaver on never blanking and never going into
screensaving mode, and the displays gets blank always after 10 minutes
(and besides this, at xscreensaver-demo (from terminal command line),
i set 720 minutes at 'Blank After', and 1000 minutes at
Advanced:DisplayPowerManagement )

The very annoying resulting situation is i can't see decently, for
example, any video or dvd lasting more than 10 minutes, or video
streaming, being far away from the computer, keyboard or mouse -
always being annoyed with this display blanking situation

How can this bug be fixed, and where else should i change (like
configuration files) for fixing it? btw, i think these preference
interfaces like xscreensaver-demo should be enough for this...

(for example, just imagine how silly would be a situation like this on
ubuntu-tv - http://www.youtube.com/watch?v=bwiFrN-fZTg )

thanks and cheers,
p.
