x settings differs from gnome settings

[peter van zwol]

G'day,

Every time when I boot up my PC with Fedora 8 I get the warning that my 
settings for the display between de X settings and those by Gnome 
differs from each other. I can choose which one to use. But my choise is 
not stored so the question pops up the next time of starting my PC.
I think the cause of this has to do something with an update of my 
Fedora software recently.
But what to do to get rid of this conflict?

Kind regards,
Peter
