The laptop is a Thinkpad p50 with a quadro M1000M. To get this bug I am using the hybrid graphics mode. This problem occurs with 375.82 and also with the new 384 driver. When using gdm3 and options nvidia_375_drm modeset=1 the greeter only shows the laptop screen. My two external displays are not turned on. they do not appear in the listing of diplays in xrandr the problem does not occur if modeset=0 or if I use lightdm I suspect this is a known bug but I am not quite sure so I'm reporting it.
