Ahhh, I see.  I was running it in a Konsole but as root.  I did try to 
change to my user from root but it was the same.  Soooo, I set up a menu 
entry to run Konsole as my user from the start.  That seems to work MUCH 
better.  I get what I think we were both expecting.

I have one more question.  When I set this the way I want it, will this 
affect ONLY kde or will it affect everything?  When I am at the login 
screen, kdm, I want it to turn off after 5 minutes.  I have that set in 
xorg.  When I log out I am usually leaving the house so no need for it 
to be on for very long.  I do want it to stay on for a long while when I 
am logged in tho.  I have a slide show set up for the background and I 
watch it until I fall asleep.  Plus, I watch TV shows on it sometimes too.

Now to go tinker with this a bit.  Thanks.  I'm getting these issues 
dealt with one at a time but we're making progress.
