You by any chance don't have dual-headed X configured? I had a similar problem and after removing my second ServerLayout section + RgbPath + 'AllowEmptyInput' in xorg.conf, everything seems to work again (even my dual display ???)

Section "ServerLayout"
        Identifier     "X.org Configured"
        Screen      0  "PANEL" 0 0
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"
        Option         "AllowEmptyInput" "off"
EndSection
