I'm still trying to figure out this problem.  Thanks to Bryan Halter,
I've been able to determine that I need to use the xset command, but I
can't figure out where to put that line so that it takes effect on the
login screen.

I think it's .xinitrc in the user's home directory, but that's only
AFTER a user has logged in.  What about before a user has logged in
(i.e. while it's on the graphical "Fedora Core" login screen)? 
rc.local is obviously too early in the process.

Help!
Thanks
