There was a bug in X several months back that resulted in the same
symptoms.  As I recall, it appeared with first X version that defaulted
to using hal and dbus -- a work around was to tweak xorg.conf to
restore the old behaviour, by adding entries like this:

Section "ServerLayout"
	[...]
        Option         "AllowEmptyInput" "off"
EndSection

Check the archives for the full story -- there were more things to
twiddle than just that option.

The problem was fixed within a couple of weeks, and given that you
should have rebuilt everything as part of your 7.2 to 8.0 upgrade, it
really shouldn't be affecting you.  It might be the case that the same
sort of work arounds help in your case though.

	Cheers,
