I had similar issue on an old HP laptop, but not sure if it is the same 
cause as yours.

Please try to set Option "AllowEmptyInput" "false" in /etc/X11/xorg.conf 
(uncomment the line in Section Serverlayout)

Section "ServerLayout"
         Identifier     "X.org Configured"
         Screen      0  "Screen0" 0 0
         InputDevice    "Mouse0" "CorePointer"
         InputDevice    "Keyboard0" "CoreKeyboard"
         #Option "AllowEmptyInput" "false"
EndSection
