[Fedora-livecd-list] Keyboard input no longer accepted in X Windows

Hello,   I booted a new Live CD I generated within the last couple of days, and on entering the graphical login screen the system will not accept any characters I type into the userid or password fields.  Has anyone else had this problem?  It does appear that various xorg rpms were updated recently.  Could this be part of the issue?   As always, any help is appreciated.   Todd
