I've discovered something else odd going on that seems to be related to 
this issue.

If I activate the screen lock by hand, and the screensaver starts 
running, I noticed that within say 30 seconds the screensaver pauses and 
displays the login box - as if someone pressed a key on the keyboard or 
moved the mouse.  This would explain why the screensaver never engages - 
it keeps getting keyboard or mouse input (or at least thinks it is) that 
prevents it.

But that makes the problem even more puzzling, as my hands are not on 
the keyboard or mouse.  My next guess was that perhaps there's a broken 
key on the keyboard that keeps pressing.  But I used xev, and it shows 
no keyboard or mouse events while my hands are off.

Is anyone else seeing similar behavior?  If not, I guess I'll have to 
assume this is a hardware problem.  But if so, I'd appreciate any 
suggestion on how I might go about debugging.

Thanks,

DR
