xautolock does nothing...

[Tony Baldwin <photodharma@gmail.com>]

I have xautolock and slock installed, and have tried to use this:
xautolock -time 5 -locker slock
for those times I walk away and forget to engage slock.
But it doesn't work.
Any idea why?

I swear, it's on:
tony@deathstar:~$ ps aux | grep xautolock
tony     18390  0.0  0.0   2944  1044 pts/0    T    14:54   0:00 
xautolock -time 5 -locker slock

But I can walk away for 20 minutes (much more than the 5 min requested) 
and find my screen not locked.

thanks for any assistance.
