RH9 KDE/Gnome autologout

["Thomas M. Langley" <langley nersc gov>]

Did a boxed upgrade from RH8 to RH9 yesterday. Upon logging into KDE was 
pleased to find that the display (especially the Mozilla fonts) seem to be 
getting cleaner and cleaner. However, I walked away from my desk and when I 
returned found out I had been logged out. Never had that happen before. Later 
I was pausing to think and was logged out again. Have noticed that the time 
to logout is not consistent, sometimes as few as 3-5 minutes sometime > 20 
minutes. Anyone else experienced this? Any solutions?
Thanks,
