I wonder if this is related to a problem I had, 1 or 2 years ago, where system-config-display (?) said that it was updating xorg.conf, but, in fact, it did not update it. Sometimes the GUIs do not work as advertised. There was some command which ended in --rebuild (?) to generate a completely new xorg.conf file. Possibly that would help you, with part of this problem?
