screensaver in 9.10

[R Kimber]

I have 'Activate screensaver when computer is idle' checked, and I have
'Regard the computer as idle after' set to 45 minutes.

However, the screensaver activates after 20 minutes.  Is there some other
setting I need to set, or is there a known bug?  I looked on launchpad, but
couldn't see that particular issue, though I may have missed it.

Anyone else unable to control the idle time?
