Kubuntu does not shut down when external monitor attached through displayport

Binary package hint: xserver-xorg-video-intel

After connecting and configuring my lenovo thinkvision screen via the display port, the machine does not fully shut down, it exits the DE, drops to the plymouth shoutdown screen and flickers between the external and internal screens. (the machine is a HP probook 5320m laptop). I have left it this way for ~15-20 mins with out successfully shutting down. I have it configured to only display on the external screen when inside the DE.
