Thanks to all of you for your replies.  I have just deactivated the
screensaver and will see what happens.   I do have a long list of
screensavers and have Random as the selection The problem was not a
screensaver lock, it is a restart of X putting me back to the GDM
login window.

Mikkel: Thanks for the log message post.  /var/log/messages does have
a lot of lines like

Dec  8 07:36:04 f8 gdm-binary[10911]: WARNING:
gdm_slave_xioerror_handler: Fatal X error - Restarting :0

which I believe is X restarting.  I did find some kernel restart lines
also, but I believe those were all from times I rebooted manually.

I am back running Gnome/GDM, after running KDE.KDM for about a month.
This behavior is just since switching environments.  Please no flame
wars about Gnome/KDE.  They both have great features.
