gnome-screensaver issues

[D Canfield]

I don't see anything in bugzilla about this, so I'm guessing this is 
somehow specific to just me or my hardware, but I'm not sure what would 
be the cause: 

I've got gnome-screensaver enabled at 10 minutes, and I have the lock 
screen option un-checked.  At 10 minutes, the screen goes black, but 
then I can't get out of the screensaver using the mouse or keyboard.  If 
I hit ctrl-alt-F1 to switch to a text console, login, and then killall 
gnome-screensaver, I can then get back into my X session.  But then the 
screen starts blanking (and turning off my monitor) every 1 minute if idle.

I'm on a thinkpad T43 with an ATI chipset.  Does this make any 
difference?  Any thoughts?
