Something is keeping my X awake

[Vladimir Dergachev]

This normally happens when movie player or VNC turns it off (you don't 
want the screen locking while the movie is playing).

If any of such programs were terminated before they could restore the 
regular behaviour, the screen won't lock.

Try using "xset q" to see what the current state is. You can use "xset 
+dpms" to enable power saving again.
