How to stop "session was locked"

[joe at actionline.com]

On a new install of kubuntu, there are many things to appreciate,
including the fact that suspend works perfectly ... except for one
annoying trait.

After I close the lid, and the system goes into suspend mode, then open
the lid again, there is an annoying pop-up that requires a password to
"unlock" the system.

What do I need to do to eliminate this annoying requirement to enter a
password to unlock the system?
