I have this problem with two HD monitors plugged into the DVI ports on the docking port.
I have a 3rd monitor in the VGA port and on login screen - all 4 displays are showing (including laptop) although moving mouse around does cause some issues. After logging in - I have two monitors (both HD, in DVI ports), and laptop/VGA is off. I fixed my issues simply by removing nvidia-settings (sudo apt-get --purge remove nvidia-settings) and doing the rest in Display Settings. When I had nvidia-settings installed, I often had issues: 1. nvidia-settings will only show two detected monitors (in DVI ports) 2. Display Settings will show 4 displayers (VGA and laptop included) however attempting to change any settings in this cause a lot of problems (ie - it'll freeze for a period of time, mess up the displays etc. After much pain I managed to disable laptop and VGA via this and it worked then) However after I removed nvidia-settings: Display Settings work just fine and show two monitors only (both DVI) and work perfectly. So it appears that nvidia-settings is somehow conflicting with Display Settings in this particular case. My solution was simply to just uninstall nvidia-settings and it works. I hope this works for others - if you could confirm the same thing?
